Gomaa, Adel A.; El-Sers, Dalia A.; Al-Zokeim, Nahla I.; Gomaa, Mohamed A. published the artcile< Amelioration of experimental metabolic syndrome induced in rats by orlistat and Corchorus olitorius leaf extract; role of adipo/cytokines>, Recommanded Product: (S)-(S)-1-((2S,3S)-3-Hexyl-4-oxooxetan-2-yl)tridecan-2-yl 2-formamido-4-methylpentanoate, the main research area is orlistat Corchorus olitorius leaf extract metabolic syndrome amelioration cytokines; Corchorus olitorius ; cytokines; histopathology; lipid profile; obesity.

To determine the efficacy of Corchorus olitorius (C. olitorius) leaf extract in the prevention of metabolic syndrome induced in rats by high-fat diet (HFD) and compare it with that of orlistat. Phytochem. anal. was performed. Effect of orlistat and C. olitorius extract on lipase activity and acute food intake were investigated. Body weight, biochem. parameters and histopathol. examination were demonstrated. Corchorus olitorius extract inhibited the pancreatic lipase activity, but orlistat was more potent. Cumulative food intake has not changed by the tested agents. In obese rats, C. olitorius or orlistat significantly decreased weight gain and visceral white adipose tissue. They exhibited a significant reduction in serum glucose, total cholesterol, triglycerides, low d. lipoprotein cholesterol, free fatty acids, IL-1β, tumor necrosis factor-α (TNF-α), insulin and leptin levels of obese rat groups while high d. lipoprotein cholesterol and adiponectin levels were significantly increased by them. Histopathol. examination of the liver revealed that C. olitorius was more effective than orlistat in the alleviating of steatosis and adipocyte hypertrophy shown in obese control rats. Corchorus olitorius is effective as orlistat in preventing obesity, hyperlipidemia, steatosis and insulin resistance. These actions may be mediated by inhibiting of lipase activity, TNF-α, IL-1β and leptin resistance along with increasing of adiponectin.

Sharma, Shikha; Ghosh, Sunil K.; Sharma, Joti N. published the artcile< Dialkylmethyl-2-(N,N-diisobutyl)acetamidoammonium iodide as a ruthenium selective ligand from nitric acid medium>, Formula: C10H20ClNO, the main research area is dialkylmethyldiisobutylacetamidoammonium iodide ruthenium ligand nitrate; Alkylammonium acetamides; Iodide ion; Ruthenium; Separation; Solvent extraction.

A new class of quaternary ammonium iodide based ligands with 2-(N,N-diisobutyl)acetamide as an alkyl appendage were designed, synthesized and tested for their ability to extract ruthenium selectively from nitric acid medium. The 2-(N,N-diisobutyl)acetamido ammonium iodide with two Pr and a Me substituents showed best results for the recovery of ruthenium. The optimized concentration of the solvent was 0.2 M in 30% isodecyl alc./n-dodecane. The stoichiometry of the complex was ascertained by slope anal. method and was 1:1 with respect to ligand L+I- and Ru(NO)(NO3)3. Ruthenium formed an adduct of structure LRu(NO)(NO3)3I in the extraction medium. Iodide ion played an important role in the formation of the stable and extractable complex of ruthenium. No extraction was observed when iodide was replaced by nitrate anion in the ligand. The ligand also showed good selectivity for ruthenium in the presence of other metal ions commonly found in nitric acid solutions of nuclear waste.

Vu, Huu-Manh; Yong, Jia-Yuan; Chen, Fei-Wu; Li, Xu-Qin; Shi, Guo-Qing published the artcile< Rhodium-Catalyzed C(sp2)-H Amidation of Azine with Sulfonamides>, Synthetic Route of 1524-40-9, the main research area is regioselective rhodium catalyzed amidation azine sulfonamide.

Direct C-H amidation of azine with sulfonamide was developed for the first time. The reactions proceeded smoothly under benign conditions and gave the corresponding products with high selectivity. This approach shows high regioselectivity, wide substrate scope, and functional group tolerance. Addnl., this transformation can also be scaled up to the gram level. This strategy allows for the direct preparation of ortho-sulfonamide-substituted ketone products, thus providing a good complement to previous C-H amidation.

The prognosis for cervical cancer (CC) patients with lymph node metastasis (LNM) is extremely poor. Lipid droplets (LDs) have a pivotal role in promoting tumor metastasis. The crosstalk mechanism between LDs and LNM modulated in CC remains largely unknown. This study aimed to construct a miRNA-dependent progonostic model for CC patients and investigate whether miR-532-5p has a biol. impact on LNM by regualting LDs accumulation. LASSO-Cox regression was applied to establish a prognostic prediction model. miR-532-5p had the lowest P-value in RNA expression (P < 0.001) and prognostic prediction (P < 0.0001) and was selected for further study. The functional role of the prognostic miR-532-5p-correlated competing endogenous RNA (ceRNA) network was investigated to clarify the crosstalk between LDs and LNM. The underlying mechanism was determined using site-directed mutagenesis, dual luciferase reporter assays, RNA immunoprecipitation assays, and rescue experiments A xenograft LNM model was established to evaluate the effect of miR-532-5p and orlistat combination therapy on tumor growth and LNM. A novel 5-miRNAs prognostic signature was constructed to better predict the prognosis of CC patient. Further study demonstrated that miR-532-5p inhibited epithelial-mesenchymal transition and lymphangiogenesis by regulating LDs accumulation. Interestingly, we also found that LDs accumulation promoted cell metastasis in vitro. Mechanistically, we demonstrated a miR-532-5p-correlated ceRNA network in which LINC01410 was bound directly to miR-532-5p and effectively functioned as miR-532-5p sponge to disinhibit its target gene-fatty acid synthase (FASN). Combined therapy with miR-532-5p and FASN inhibitor-orlistat further inhibited tumor growth and LNM in vivo. Our findings highlight a LD accumulation-dependent mechanism of miR-532-5p-modulated LNM and support treatment with miR-532-5p/orlistat as novel strategy for treating patients with LNM in CC.

Gorgojo-Martinez, Juan J.; Basagoiti-Carreno, Belen; Sanz-Velasco, Alberto; Serrano-Moreno, Clara; Almodovar-Ruiz, Francisca published the artcile< Effectiveness and tolerability of orlistat and liraglutide in patients with obesity in a real-world setting: The XENSOR Study>, Category: amides-buliding-blocks, the main research area is obesity cardiovascular risk factor orlistat liraglutide.

To evaluate in a real-world setting the effectiveness of two drugs, orlistat and liraglutide, in patients with overweight or obesity and insufficient weight loss (WL) after a lifestyle modification program. Retrospective, observational cohort study comparing clin. outcomes of orlistat 120 mg three times a day and liraglutide (up to 3 mg daily) in adult patients with BMI =30 kg/m2 or =27 kg/m2 with at least a weight-related comorbidity who had failed to lose at least 5% of their weight after 6 mo of lifestyle modification. The co-primary end-points, assessed at 3-6 mo and at the end of the follow-up, were weight change from baseline, proportion of patients who lost at least 5% of their baseline weight and adjusted differences in WL between both drugs. Five hundred patients, 400 in the group of orlistat (age 47.0, weight 107.8 kg) and 100 in the group of liraglutide (age 51.9 years, weight 105.1 kg), were included. WL with liraglutide (-7.7 kg) was significantly greater than that observed with orlistat (-3.3 kg), and more individuals lost at least 5% of their baseline weight with liraglutide (64.7%) than with orlistat (27.4%). In this real-world study, liraglutide showed a greater effectiveness in WL compared with orlistat and improved several obesity-associated metabolic and cardiovascular risk factors.

Suleiman, Joseph Bagi; Nna, Victor Udo; Zakaria, Zaida; Othman, Zaidatul Akmal; Bakar, Ainul Bahiyah Abu; Mohamed, Mahaneem published the artcile< Obesity-induced testicular oxidative stress, inflammation and apoptosis: Protective and therapeutic effects of orlistat>, HPLC of Formula: 96829-58-2, the main research area is orlistat antiobesity agent testicular oxidative stress inflammation apoptosis obesity; Apoptosis; High-fat diet; Inflammation; Obesity; Orlistat; Oxidative stress.

The objective of this study was to determine effects of the anti-obesity drug orlistat, on testicular oxidative stress, inflammation and apoptosis in high-fat diet (HFD)-fed rats. Twenty-four adult male Sprague Dawley rats weighing 250-300 g were randomized into four groups (n = 6/group), namely; normal control (NC), high-fat diet (HFD), HFD plus orlistat (10 mg/kg body weight/day administered concurrently for 12 wk) (HFD + Opr) and HFD plus orlistat (10 mg/kg body weight/day administered 6 wk after induction of obesity) (HFD + Ot) groups. Antioxidant enzymes activities were significantly decreased, while mRNA levels of pro-apoptotic markers (p53, Bax/BCl-2, caspase-9, caspase-8 and caspase-3) were significantly increased in the testis of HFD group relative to NC group. Furthermore, mRNA levels of pro-inflammatory markers (nuclear factor kappa B, inducible nitric oxide synthase, tumor necrosis factor alpha and interleukin (IL)-1beta increased significantly, while anti-inflammatory marker (IL-10) decreased significantly in testis of the HFD group relative to NC group. However, in both models of orlistat intervention (protective and treatment models) up-regulated antioxidant enzymes, down-regulated inflammation and apoptosis were observed in the testis of HFD-fed rats. Orlistat ameliorated testicular dysfunction by attenuating oxidative stress, inflammation and apoptosis in HFD-fed rats, suggesting its potential protective and therapeutic effects in the testis compromised by obesity.

Sivey, John D.; Roberts, A. Lynn published the artcile< Abiotic Reduction Reactions of Dichloroacetamide Safeners: Transformations of ""Inert"" Agrochemical Constituents>, Safety of 2-Chloro-N,N-diisobutylacetamide, the main research area is abiotic reduction reaction modeling dichloroacetamide safener transformation.

Safeners are so-called “”inert”” constituents of herbicide formulations added to protect crops from the toxic effects of herbicides. We examined the reactivity of three dichloroacetamide safeners and 12 structural analogs [all neutral compounds of the form Cl2CXC(=O)NRR’; X = H, Cl; R-groups include alkyl, branched alkyl, n-allyl, and cyclic moieties] in one homogeneous and two heterogeneous reductant systems: solutions of Cr(H2O)62+, suspensions of FeII-amended goethite, and suspensions of FeII-amended hematite. Analyses of reaction products indicate each safener can undergo stepwise hydrogenolysis (replacement of chlorine by hydrogen) in each system at near-neutral pH. The first hydrogenolysis step generates compounds similar (in one case, identical) to herbicide active ingredients. Rates of product formation and (when reactions were sufficiently fast) parent loss were quantified; reaction rates in heterogeneous systems spanned 2 orders of magnitude and were strongly influenced by R-group structure. The length of n-alkyl R-groups exerted opposite effects on hydrogenolysis rates in homogeneous vs. heterogeneous systems: as R-group size increased, reduction rates in heterogeneous systems increased, whereas reduction rates in the homogeneous system decreased. Branched alkyl R-groups decreased hydrogenolysis rates relative to their straight-chain homologs in both homogeneous and heterogeneous systems. Reaction rates in heterogeneous systems can be described via polyparameter linear free energy relationships employing mol. parameters likely to influence dichloroacetamide adsorption. The propensity of dichloroacetamide safeners to undergo reductive transformations into herbicide-like products challenges their classification as “”inert”” agrochem. ingredients.

Owing to alarming increase of diabetes mellitus around the world, there is a need to discover new mols. to tackle with the problem. In this work, sulfonamides and sulfonylurea-sulfonamide hybrids were synthesized from simple mol. of 4-aminobenzenesulfonamide by its reaction with aryl sulfonyl chlorides. Anti-diabetic activities of these pharmacophores were studied by oral glucose tolerance test (OGTT) percentage anal. on Sprague Dawley (SD) rats at the dose of 20mg/kg using glibenclamide (GC). Among these synthesized pharmacophores, six compounds exhibited percentage reduction (20.47 ± 2.54 to 44.97 ± 2.16%) and (20.79 ± 1.55 to 37 ± 2.94%) in blood glucose level at 20mg/kg dose compared to glibenclamide (74 ± 3.10% reduction) 50mg/kg dose of glibenclamide after 2 and 5 h of oral administration resp. Present results showed that these compounds might be excellent addition in the drugs used to suppress the higher level of blood glucose level in diabetes mellitus.
