A novel endothelium-independent effect of insulin on basal vascular tone in cafeteria diet-induced hypertensive rats was written by Joo Turoni, Claudio M.;Maranon, Rodrigo O.;Alberstein, Ramon A.;Sanchez, Romel S.;Peral de Bruno, Maria. And the article was included in European Journal of Pharmacology in 2022.Product Details of 10238-21-8 This article mentions the following:

Insulin vasorelaxant effect in metabolic syndrome has been shown on precontracted vessels. However, the insulin effects on basal vascular tone and its interrelationship with nitric oxide (NO) and K-channels are unknown. To test the effect of insulin on the basal vascular tone in isolated aortic rings from the cafeteria diet-induced hypertensive rats and to determine the role of NO and K-channels on this insulin effect. Male Wistar rats were randomized into two groups: one group fed with a cafeteria diet (CafR) and another fed with a standard chow diet (control rats: CR). Then, in isolated aortic rings, the insulin effect on the basal tone and the role of K-channels were evaluated. Also, the endothelial function, NO levels, and resting membrane potential were measured. CafR increased blood pressure (138 ± 6.2 mmHg; n = 9 vs. CR: 109 ± 1.4 mmHg; n = 9; p < 0.001) and vascular basal tone. Insulin 400 mU/mL reduced basal tone in aortic rings (-284 ± 47 mg; n = 9). This effect was unaffected by endothelium removal or N^G-nitro-L-arginine Me ester (L-NAME) treatment. Likewise, CafR showed low NO levels and a hyperpolarized resting membrane potential. Insulin decreased the resting membrane potential and the K_Ca and Kv channels blockers abolished this effect. In CafR, endothelial dysfunction is accompanied by an increased basal tone. Insulin reduced it by Kv and KCa channels dependent mechanisms, using an endothelium-independent pathway. These results highlight a novel insulin effect on basal tone of aortic rings from animals with metabolic syndrome and endothelial dysfunction, pathophysiol. conditions associated with human hypertension. In the experiment, the researchers used many compounds, for example, 5-Chloro-N-(4-(N-(cyclohexylcarbamoyl)sulfamoyl)phenethyl)-2-methoxybenzamide (cas: 10238-21-8Product Details of 10238-21-8).

5-Chloro-N-(4-(N-(cyclohexylcarbamoyl)sulfamoyl)phenethyl)-2-methoxybenzamide (cas: 10238-21-8) belongs to amides. Because of the greater electronegativity of oxygen, the carbonyl (C=O) is a stronger dipole than the N–C dipole. The presence of a C=O dipole and, to a lesser extent a N–C dipole, allows amides to act as H-bond acceptors. As a result of interactions such as these, the water solubility of amides is greater than that of corresponding hydrocarbons. These hydrogen bonds are also have an important role in the secondary structure of proteins.Product Details of 10238-21-8

E4orf1-induced reduction in endogenous insulin level is independent of pancreas endocrine function was written by Akheruzzaman, Md;Hegde, Vijay;Siddik, Abu Bakkar Md;Feizy, Zahra;Shin, Andrew C.;Dhurandhar, Nikhil V.. And the article was included in International Journal of Obesity in 2022.SDS of cas: 10238-21-8 This article mentions the following:

Obesity is often associated with hyperinsulinemia due to insulin resistance. In mice models of hyperinsulinemia, adenovirus-derived E4orf1 protein promotes glucose disposal via insulin-independent pathway, and reduces insulin response to glucose load, described as its “Insulin Sparing Action”. This is likely because less insulin is needed for disposing glucose in presence of E4orf1, however, there are other potential possibilities. This study determined if E4orf1 reduces insulin response to glucose load because it (a) suppresses the ability of pancreatic β-cells to secret insulin, or (b) upregulates glucagon production by the pancreas. C57BL/6J wild type (control) and transgenic C57BL/6J (E4orf1) mice that express E4orf1 protein in adipose tissue upon doxycycline feeding, were used. Post-doxycycline feeding, insulin and glucagon secretion in response to glibenclamide or phenylephrine were compared between the two groups. The pancreases were examined for histol. changes. In response to glibenclamide, E4orf1 mice secreted more insulin and exhibited lower blood glucose compared to control (47.4 ± 4.4 vs 27.4 ± 3.7 mg/dL, p < 0.003), but showed no difference in glucagon secretion. Post-phenylephrine injection, no differences were observed between the two groups for glucagon or insulin, except E4orf1 mice had a lower blood glucose rise after 10-min of injection compared to the control (39.7 ± 4.7 vs. 58.3 ± 7.5 mg/dL, p < 0.05). E4orf1 mice had significantly larger pancreatic islets and higher number of islets per mm2 tissue area. Neither the size nor the number of islets met the criteria of hypertrophy or hyperplasia. E4orf1 retains and may enhance the ability of the pancreases to secret insulin in response to insulin secretagogue. Glucagon does not seem to play a role in the Insulin Sparing Action of E4orf1. Overall, the histol. studies support better pancreatic islet health in presence of E4orf1, compared to that in control mice. The “insulin-independent” role of E4orf1 has potential therapeutic implications in addressing hyperinsulinemia in obesity. In the experiment, the researchers used many compounds, for example, 5-Chloro-N-(4-(N-(cyclohexylcarbamoyl)sulfamoyl)phenethyl)-2-methoxybenzamide (cas: 10238-21-8SDS of cas: 10238-21-8).

5-Chloro-N-(4-(N-(cyclohexylcarbamoyl)sulfamoyl)phenethyl)-2-methoxybenzamide (cas: 10238-21-8) belongs to amides. Amides are pervasive in nature and technology. Proteins and important plastics like Nylons, Aramid, Twaron, and Kevlar are polymers whose units are connected by amide groups (polyamides); these linkages are easily formed, confer structural rigidity, and resist hydrolysis. In simple aromatic amides, fragmentation occurs on both sides of the carbonyl group. If a hydrogen is available in N-substituted aromatic amides, it tends to migrate and form an aromatic amine and the loss of a ketene.SDS of cas: 10238-21-8

Brain Targeting, Antioxidant Polymeric Nanoparticles for Stroke Drug Delivery and Therapy was written by Wu, Haoan;Peng, Bin;Mohammed, Farrah S.;Gao, Xingchun;Qin, Zhenpeng;Sheth, Kevin N.;Zhou, Jiangbing;Jiang, Zhaozhong. And the article was included in Small in 2022.Name: 5-Chloro-N-(4-(N-(cyclohexylcarbamoyl)sulfamoyl)phenethyl)-2-methoxybenzamide This article mentions the following:

Ischemic stroke is a leading cause of death and disability and remains without effective treatment options. Improved treatment of stroke requires efficient delivery of multimodal therapy to ischemic brain tissue with high specificity. Here, this article reports the development of multifunctional polymeric nanoparticles (NPs) for both stroke treatment and drug delivery. The NPs are synthesized using an reactive oxygen species (ROS)-reactive poly (2,2′-thiodiethylene 3,3′-thiodipropionate) (PTT) polymer and engineered for brain penetration through both thrombin-triggered shrinkability and AMD3100-mediated targeted delivery. It is found that the resulting AMD3100-conjugated, shrinkable PTT NPs, or ASPTT NPs, efficiently accumulate in the ischemic brain tissue after i.v. administration and function as antioxidant agents for effective stroke treatment. This work shows ASPTT NPs are capable of efficient encapsulation and delivery of glyburide to achieve anti-edema and antioxidant combination therapy, resulting in therapeutic benefits significantly greater than those by either the NPs or glyburide alone. Due to their high efficiency in brain penetration and excellent antioxidant bioactivity, ASPTT NPs have the potential to be utilized to deliver various therapeutic agents to the brain for effective stroke treatment. In the experiment, the researchers used many compounds, for example, 5-Chloro-N-(4-(N-(cyclohexylcarbamoyl)sulfamoyl)phenethyl)-2-methoxybenzamide (cas: 10238-21-8Name: 5-Chloro-N-(4-(N-(cyclohexylcarbamoyl)sulfamoyl)phenethyl)-2-methoxybenzamide).

Phytochemical Analysis and hypoglycemic potential of Filago hurdwarica (Wall. ex DC.) Wagenitz in alloxan induced diabetic mice. was written by Rahman, S;Jan, Gul;Jan, F Gul;Rahim, H Ur. And the article was included in Brazilian journal of biology = Revista brasleira de biologia in 2022.Formula: C23H28ClN3O5S This article mentions the following:

Plants have profound therapeutic benefits, more economical treatments, fewer side effects, and a relatively cheap cost, making them a source of drugs for protective, preventative, curative, or conducive purposes and creating novel phytomedicines. Plant derived medicines are relatively safe compared to synthetic medicines. Many plants have proved to successfully aid in the treatment of diabetes including Filago hurdwarica (Wall. ex DC.) Wagenitz. The current investigations were therefore designed to assess the phytochemical, antioxidant, antidiabetic, and antihyperlipidemic activities of F. hurdwarica. The phytochemical investigations and antioxidant activities of different extracts were carried out using standard chemical tests, DPPH, and H2O2 scavenging assays. F. hurdwarica plant extract in Hydromethanolic solution were prepared by Soxhletation method and stored in refrigerator at 4°C for two days before use. Swiss Albino mice were made diabetic by a single dose of alloxan (150 mg/kg). Hydromethanolic plant extract and fractions of F. hurdwarica were screened for antidiabetic activity and given to the alloxan-induced diabetic mice at a concentration of 150-250 mg/kg of body weight in different groups of 6 diabetic mice each orally once a day for 15 days. Glibenclamide is also given to another group to as a standard drug to support the result at a dose of 10 mg/kg of body weight orally once a day for 15 days. Blood glucose levels and body weights of mice were measured on 0, 4, 7, 11 and 15th days. The study found that the extract was safe up to the dose level of 2000 mg/kg and the dose response effect of chloroform extract (150-250 mg/kg) of F. hurdwarica showed expressive antihyperglycemic effects and also improved other altered biochemical parameters associated with diabetes. The FTIR and XRD spectra demonstrated the occurrence of phenols, alcohols, alkenes, alkyl halides, ketones, and aromatic compounds and confirmed the amorphous nature of the extract. GC-MS spectral analysis showed the tentative presence of 31 phytochemical constituents in the chloroform extract of F. hurdwarica with different retention time. To conclude, the chloroform extract (250 mg/kg) of F. hurdwarica revealed considerable antioxidant, antihyperglycemic, and antihyperlipidemic potential and is safe for treating diabetes and related complications. In the experiment, the researchers used many compounds, for example, 5-Chloro-N-(4-(N-(cyclohexylcarbamoyl)sulfamoyl)phenethyl)-2-methoxybenzamide (cas: 10238-21-8Formula: C23H28ClN3O5S).

Purineless death as a link between growth rate and cytotoxicity by methotrexate was written by Hryniuk, William M.. And the article was included in Cancer Research in 1972.Product Details of 7413-34-5 This article mentions the following:

In murine S-phase lymphoblasts, Na methotrexate (Na I) [7413-34-5] produces a purineless state, the degree of which depends upon the growth rate of the population. The purineless state probably contributes to the lethal effect of I, and may explain in part the relation between growth rate and cytotoxicity of antifolates. I decreased cloning efficiency and inhibited DNA, RNA, and protein synthesis in L5178Y murine lymphoblasts from cultures proliferating at different rates. The effects of I increased with the proliferative rate. Hypoxanthine [68-94-0] completely prevented the biochem. effects of I and partially protected the cells against lethal effects of I. In the experiment, the researchers used many compounds, for example, Sodium (S)-2-(4-(((2,4-diaminopteridin-6-yl)methyl)(methyl)amino)benzamido)pentanedioate (cas: 7413-34-5Product Details of 7413-34-5).

Sodium (S)-2-(4-(((2,4-diaminopteridin-6-yl)methyl)(methyl)amino)benzamido)pentanedioate (cas: 7413-34-5) belongs to amides. Compared to amines, amides are very weak bases and do not have clearly defined acid–base properties in water. On the other hand, amides are much stronger bases than esters, aldehydes, and ketones. In simple aromatic amides, fragmentation occurs on both sides of the carbonyl group. If a hydrogen is available in N-substituted aromatic amides, it tends to migrate and form an aromatic amine and the loss of a ketene.Product Details of 7413-34-5

Polymeric micelles loaded with glyburide and vanillic acid: I. Formulation development, in-vitro characterization and bioavailability studies was written by Kaur, Jaskiran;Gulati, Monica;Famta, Paras;Corrie, Leander;Awasthi, Ankit;Saini, Sumant;Khatik, Gopal L.;Bettada, Vidya G.;Madhunapantula, SubbaRao V.;Paudel, Keshav Raj;Gupta, Gaurav;Chellappan, Dinesh Kumar;Arshad, Mohammed F.;Adams, Jon;Gowthamarajan, Kuppusamy;Dua, Kamal;Hansbro, Philip M.;Singh, Sachin Kumar. And the article was included in International Journal of Pharmaceutics (Amsterdam, Netherlands) in 2022.Name: 5-Chloro-N-(4-(N-(cyclohexylcarbamoyl)sulfamoyl)phenethyl)-2-methoxybenzamide This article mentions the following:

The co-formulation of glyburide (Gly) and vanillic acid (VA) as such in the form of nanomedicine has never been explored to treat metabolic diseases including type 2 diabetes mellitus. Both the drugs possess dissolution rate-limited oral bioavailability leading to poor therapeutic efficacy. Hence, co-loading these drugs into a nanocarrier could overcome their poor oral bioavailability related challenges. Owing to this objective, both drugs were co-loaded in amphiphilic polymeric micelles (APMs) and evaluated for their biopharmaceutical outcomes. The APMs were prepared using mPEG-b-PCL/CTAB as a copolymer-surfactant system via the liquid antisolvent precipitation (LAP) method. The design of these APMs were optimized using Box Behnken Design by taking various process/formulation based variables to achieve the desired micellar traits. The release of both the drugs from the optimized co-loaded APMs was compared in different media and displayed a remarkable sustained release profile owing to their hydrophobic interactions with the PCL core. The in vitro cytotoxicity study of co-loaded APMs on Caco-2 cells revealed 70 % cell viability in a concentration-dependent manner. The preventive effects of Gly and VA co-loaded in APMs on glucose uptake was studied in insulin-responsive human HepG2 cells treated with high glucose. The co-loading of both the drugs in optimized APMs exhibited synergistic glucose-lowering activity (p < 0.001) than raw drugs with low cytotoxicity on HepG2 cells within the test concentration This could be attributed to an increase in the relative oral bioavailability of both the drugs in APMs i.e., 868 % for Gly and 87 % for VA resp. In the experiment, the researchers used many compounds, for example, 5-Chloro-N-(4-(N-(cyclohexylcarbamoyl)sulfamoyl)phenethyl)-2-methoxybenzamide (cas: 10238-21-8Name: 5-Chloro-N-(4-(N-(cyclohexylcarbamoyl)sulfamoyl)phenethyl)-2-methoxybenzamide).

5-Chloro-N-(4-(N-(cyclohexylcarbamoyl)sulfamoyl)phenethyl)-2-methoxybenzamide (cas: 10238-21-8) belongs to amides. The solubilities of amides and esters are roughly comparable. Typically amides are less soluble than comparable amines and carboxylic acids since these compounds can both donate and accept hydrogen bonds. Tertiary amides, with the important exception of N,N-dimethylformamide, exhibit low solubility in water. Amides are stable compounds. The lower-melting members (such as acetamide) can be readily purified by fractional distillation. Most amides are solids which have low solubilities in water.Name: 5-Chloro-N-(4-(N-(cyclohexylcarbamoyl)sulfamoyl)phenethyl)-2-methoxybenzamide

Functional characterization and comparison of human and mouse organic anion transporter 1 as drugs and pesticides uptake carrier was written by Floerl, Saskia;Kuehne, Annett;Hagos, Yohannes. And the article was included in European Journal of Pharmaceutical Sciences in 2022.COA of Formula: C23H28ClN3O5S This article mentions the following:

The organic anion transporter 1 (OAT1) is mainly expressed in proximal tubule cells, where it mediates the renal uptake of endogenous and exogenous compounds Thereby, it has enormous clin. relevance particularly in drug-drug interactions. The aim of the present in vitro study was to elucidate potential species dependent disparity of human and mouse OAT1 in handling of structural diverse drugs and pesticides. A basic functional comparison of the two transporters showed a similar time-dependent uptake of the substrate para-aminohippuric acid (PAH), the affinity (Km) was 94μM for hOAT1 and 32μM for mOat1. Inhibition experiments for hOAT1 and mOat1 provided IC50 values for glibenclamide of 5.1 and 6.4μM and for probenecid of 31 and 11μM. Than the interaction of hOAT1 and mOat1 with 23 drugs and 13 pesticides was examined Three pesticides and thirteen drugs showed high inhibitory potency of 50% or more to both transporters. Furthermore, we identified rosiglitazone as a differential active inhibitor, with stronger inhibitory properties (IC50) to mOat1 (7.7μM) than to hOAT1 (31μM), and olmesartan with the most pronounced difference: The IC50 of hOAT1 (0.40μM) was 48-fold lower than of mOat1 (19μM). In conclusion, we found a strong correlation for the inhibitory effects of most drugs and pesticides on human and mouse OAT1. But the example of olmesartan shows that species differences have to be considered when extrapolating data from mouse to human. In the experiment, the researchers used many compounds, for example, 5-Chloro-N-(4-(N-(cyclohexylcarbamoyl)sulfamoyl)phenethyl)-2-methoxybenzamide (cas: 10238-21-8COA of Formula: C23H28ClN3O5S).

Thymus persicus (Ronniger ex Rech. f.) Jalas alleviates nociceptive and neuropathic pain behavior in mice: Multiple mechanisms of action was written by Abed, Donya Ziafatdoost;Sadeghian, Reyhaneh;Mohammadi, Saeed;Akram, Muhammad. And the article was included in Journal of Ethnopharmacology in 2022.Related Products of 10238-21-8 This article mentions the following:

Thymus persicus (Roniger ex Reach F.) is an Iranian endemic medicinal plant of which essential oil and various products have numerous food and pharmaceutical applications (headache and fever treatments). This modern research included Swiss mice to investigate the anti-nociceptive and anti-neuropathic effects of Thymus persicus aerial parts essential oil (TPEO). To determine TPEO′s anti-nociceptive function in the formalin-induced paw licking (FML), researchers looked at the L-arginine/NO/cGMP/KATP channel signaling pathway as well as multiple receptors as with serotonin, morphine, dopamine, and peroxisome proliferator-activated receptors. The CVC or cervical spinal cord contusion exemplar has also been used to induce neuropathic pain. TPEO (50, 100, and 150 mg/kg) relative to control mice in the phase-II of FML provided strong antinociception (p < 0.05, p < 0.01, p < 0.001, resp.). Furthermore, methylene blue, glibenclamide, Nω-nitro-L-arginine Me ester, naloxonazine, nor-binaltorphimine, prazosin, yohimbine, and ondansetron pre-treating restored the TPEO anti-nociceptive activity in the FML (phase-II) exemplar (p < 0.05). In phase-II of the FML exemplar, carvacrol (one of the active components of TPEO) also greatly reduced pain (p < 0.001). Likewise, in CVC mice, TPEO altered mech. allodynia and hyperalgesia. It was attained magnificently that TPEO could exerts antinociceptive effects through the involvement of L-arginine/NO/cGMP/KATP signaling pathway, adrenergic, opioid, and serotonin receptors. Moreover, it is demonstrate that anti-neuropathic activity of TPEO may be mediated by inflammatory function. In the experiment, the researchers used many compounds, for example, 5-Chloro-N-(4-(N-(cyclohexylcarbamoyl)sulfamoyl)phenethyl)-2-methoxybenzamide (cas: 10238-21-8Related Products of 10238-21-8).

5-Chloro-N-(4-(N-(cyclohexylcarbamoyl)sulfamoyl)phenethyl)-2-methoxybenzamide (cas: 10238-21-8) belongs to amides. In primary and secondary amides, the presence of N–H dipoles allows amides to function as H-bond donors as well. Thus amides can participate in hydrogen bonding with water and other protic solvents; the oxygen atom can accept hydrogen bonds from water and the N–H hydrogen atoms can donate H-bonds. Ionic, or saltlike, amides are strongly alkaline compounds ordinarily made by treating ammonia, an amine, or a covalent amide with a reactive metal such as sodium.Related Products of 10238-21-8

Incretins as a Potential Treatment Option for Gestational Diabetes Mellitus was written by Pilszyk, Aleksandra;Niebrzydowska, Magdalena;Pilszyk, Zuzanna;Wierzchowska-Opoka, Magdalena;Kimber-Trojnar, Zaneta. And the article was included in International Journal of Molecular Sciences in 2022.Category: amides-buliding-blocks This article mentions the following:

Gestational diabetes mellitus (GDM) is a metabolic disease affecting an increasing number of pregnant women around the world. It is not only associated with numerous perinatal complications but also has long-term consequences impacting maternal health and fetal development. To prevent them, it is important to keep glucose levels under control. As much as 15-30% of GDM patients will require treatment with insulin, metformin, or glyburide. With that in mind, it is crucial to keep searching for novel and improved pharmacotherapies. Nowadays, there are ongoing studies investigating the use of other groups of drugs that have proven successful in the treatment of T2DM. Glucagon-like peptide-1 (GLP-1) receptor agonist and dipeptidyl peptidase-4 (DPP-4) inhibitor are among the drugs targeting the incretin system and are currently receiving significant attention. The aim of our review is to demonstrate the potential of these medications in treating GDM and preventing its later complications. It seems that both groups may be successful in the GDM management used alone or as an addition to better-known drugs, including metformin and glyburide. However, more clin. trials are needed to confirm their importance in GDM treatment and to demonstrate effective therapeutic strategies. In the experiment, the researchers used many compounds, for example, 5-Chloro-N-(4-(N-(cyclohexylcarbamoyl)sulfamoyl)phenethyl)-2-methoxybenzamide (cas: 10238-21-8Category: amides-buliding-blocks).

The effect of buffer species on biorelevant dissolution and precipitation assays – Comparison of phosphate and bicarbonate buffer was written by Krollik, Katharina;Lehmann, Andreas;Wagner, Christian;Kaidas, Jonathan;Kubas, Holger;Weitschies, Werner. And the article was included in European Journal of Pharmaceutics and Biopharmaceutics in 2022.Application In Synthesis of 5-Chloro-N-(4-(N-(cyclohexylcarbamoyl)sulfamoyl)phenethyl)-2-methoxybenzamide This article mentions the following:

Biorelevant solubility and dissolution testing is an important tool during pharmaceutical development, however, solubility experiments performed using biorelevant media often do not properly match the solubility data observed in human intestinal fluids. Even though the bicarbonate buffer is the predominant buffer system in the small intestine, in vitro assays are commonly performed using non-volatile buffer systems like phosphate and maleate. In the current study, bicarbonate- and phosphate-buffered biorelevant media were applied to solubility, dissolution, and precipitation testing for a broad range of model compounds It was found that the medium affects primarily the dissolution kinetics. However, with the knowledge of the unique buffering properties of bicarbonate buffer in the diffusion layer, it was not always possible to predict the effect of buffer species on solubility and dissolution when changing from phosphate to bicarbonate buffer. This once again highlights the special role of bicarbonate buffer for simulating the conditions in the human intestinal fluids. Moreover, it is necessary to further investigate the factors which may cause the differences in solubility and dissolution behavior when using phosphate- vs. bicarbonate-buffered biorelevant media. In the experiment, the researchers used many compounds, for example, 5-Chloro-N-(4-(N-(cyclohexylcarbamoyl)sulfamoyl)phenethyl)-2-methoxybenzamide (cas: 10238-21-8Application In Synthesis of 5-Chloro-N-(4-(N-(cyclohexylcarbamoyl)sulfamoyl)phenethyl)-2-methoxybenzamide).
