The major drawbacks of P-glycoprotein (P-gp) inhibitors at the clin. stage make the development of new P-gp inhibitors challenging and desirable. In this study, we reported our structure-activity relationship studies of 4-indolyl quinazoline, which led to the discovery of a highly effective and orally active P-gp inhibitor, YS-370. YS-370 effectively reversed multidrug resistance (MDR) to paclitaxel and colchicine in SW620/AD300 and HEK293T-ABCB1 cells. YS-370 bound directly to P-gp, did not alter expression or subcellular localization of P-gp in SW620/AD300 cells, but increased the intracellular accumulation of paclitaxel. Furthermore, YS-370 stimulated the P-gp ATPase activity and had moderate inhibition against CYP3A4. Significantly, oral administration of YS-370 in combination with paclitaxel achieved much stronger antitumor activity in a xenograft model bearing SW620/Ad300 cells than either drug alone. Taken together, our data demonstrate that YS-370 is a promising P-gp inhibitor capable of overcoming MDR and represents a unique scaffold for the development of new P-gp inhibitors.

Ruhela, R.; Panja, S.; Singh, A. K.; Dhami, P. S.; Gandhi, P. M. published the artcile< BenzoDODA grafted polymeric resin-Plutonium selective solid sorbent>, Recommanded Product: 2-Chloro-N,N-diisobutylacetamide, the main research area is wastewater treatment sorption plutonium polymeric resin; BenzoDODA SDVB resin; Plutonium; Selective; Separation; Sorption.

A new ligand grafted polymeric resin (BenzoDODA SDVB) was synthesized by covalently attaching plutonium selective ligand (BenzoDODA) on to styrene divinyl benzene (SDVB) polymer matrix. BenzoDODA SDVB resin was evaluated for separation and recovery of plutonium(IV) from nitric acid medium. Sorption of Pu(IV) was found to decrease with the increase in nitric acid concentration, with very small sorption above 7.0 M HNO3. Sorption kinetics was fast enough to achieve the equilibrium within 60 min of contact where the kinetic data fitted well to pseudo-second-order model. Sorption isotherm data fitted well to Langmuir model suggesting chem. interaction between the BenzoDODA moiety and plutonium(IV) ions. Sorption studies with some of representative radionuclides of high level waste showed that BenzoDODA SDVB is selective and therefore could be a promising solid sorbent for separation and recovery of plutonium. Further, the theor. calculations done on BenzoDODA SDVB resin suggested Pu(NO3)4·BenzoDODA (1:1) sorbed complex conformed to generally observed square antiprism geometry of the plutonium complexes, with contributions from oxygen atoms of four nitrate ions as well as from four oxygen atoms present in BenzoDODA (two phenolic ether oxygen atoms and two carbonyl oxygen atoms of amidic moiety).

Chen, Wei; Li, Yuxin; Zhou, Yunyun; Ma, Yi; Li, Zhengming published the artcile< Design, synthesis and SAR study of novel sulfonylurea derivatives containing arylpyrimidine moieties as potential anti-phytopathogenic fungal agents>, HPLC of Formula: 6961-82-6, the main research area is sulfonyl urea pyrimidinyl preparation plant pathogen antifungal activity.

Herein, three series of novel sulfonylureas (SUs) containing aromatic-substituted pyrimidines I (Ar = 4-methylphenyl, 2-furyl, 2-thienyl; R1 = H, Cl, Br, I; R2 = NO2, COOMe, Cl; R3 = H, NO2) were designed and synthesized according to pharmacophore-combination and bioisosterism strategy. The in vitro fungicidal activities against ten phytopathogenic fungi indicated that most of the title compounds I exhibited broad-spectrum and excellent fungicidal activities. Based on the preliminary fungicidal activities, a CoMFA model was constructed and the 3D-QSAR anal. indicated that either a bulky group around the 5-position of the pyrimidine ring or electropos. group around the 2-position of the benzene ring would be favor to fungicidal activities. In order to study interaction mechanism, compound I (Ar = 2-furyl; R1 = Br; R2 = Cl; R3 = H) was automatically docked into yeast acetohydroxyacid synthase (AHAS) and it further indicated that bearing bulky groups-aryl at the pyrimidine ring was critical to enhance antifungal activities. It revealed that the antifungal activity of derivatives I probably results from the inhibition of fungal AHAS. Thus, the present results strongly showed that SUs should be considered as lead compounds or model mols. to develop novel anti-phytopathogenic fungal agents.

Singh, Awadhesh Kumar; Singh, Ritu published the artcile< Pharmacotherapy in obesity: a systematic review and meta-analysis of randomized controlled trials of anti-obesity drugs>, Application In Synthesis of 96829-58-2, the main research area is meta analysis obesity orlistat phentermine lorcaserin topiramate naltrexone pharmacotherapy; Obesity; anti-obesity drugs; liraglutide 3.0 mg; lorcaserin; naltrexone plus bupropion; orlistat; phentermine plus topiramate.

Meta-anal. of obesity poses a significant increase in morbidity and mortality and thus five anti-obesity drugs have been approved currently by US FDA. Several phase 3 trials have shown a significant improvement in cardio-metabolic profile including significant weight reduction with these agents compared to placebo. We systematically searched the database of PubMed, Embase, The Cochrane Library and The ClinicalTrials.gov up to 30 Sept. 2019 and retrieved all the randomized controlled trials (RCTs) that were conducted with these five drugs for ≥1 yr and explicitly reported their efficacy vs. placebo. Subsequently, we have conducted the meta-anal. to primarily study the effect of these anti-obesity drugs on weight reduction We addnl. reviewed the effect of these drugs on other cardio-metabolic parameters including key adverse events. This meta-anal. finds a significant reduction in body weight with orlistat (N = 10,435; Δ -3.07 Kg, 95% CI, -3.76 to -2.37), phentermine plus topiramate (N = 2985; Δ -9.77 Kg; 95% CI, -11.73 to -7.81), lorcaserin (N = 16,856; Δ -3.08 Kg; 95% CI, -3.49 to -2.66), naltrexone plus bupropion (N = 3239; Δ -4.39 Kg; 95% CI, -5.05 to -3.72) and liraglutide (N = 4978; Δ -5.25 Kg; 95% CI, -6.17 to -4.32), compared to placebo (all p < 0.00001).

Baruah, Prayasee; Das, Abhinandan; Paul, Debojit; Chakrabarty, Suman; Aguan, Kripamoy; Mitra, Sivaprasad published the artcile< Sulfonylurea Class of Antidiabetic Drugs Inhibit Acetylcholinesterase Activity: Unexplored Auxiliary Pharmacological Benefit toward Alzheimer's Disease>, SDS of cas: 94-20-2, the main research area is antidiabetic sulfonylurea drugrepurposing AChE inhibitor Alzheimer’s.

Contemporary literature documents extensive research on common causative mechanisms, pathogenic pathways and dual effective remedies for Alzheimer’s disease (AD) and Type 2 diabetes mellitus (T2DM). Tolbutamide (TBM), chlorpropamide (CPM), and glyburide (GLY) are three sulfonylurea antidiabetic drugs of different generations. All these drugs were found to exhibit moderate to strong inhibitory efficiency on the neurotransmitter degrading enzyme acetylcholinesterase (AChE) with GLY (IC50 = 0.74 ± 0.02μM) being the most potent, followed by CPM (IC50 = 5.72 ± 0.24μM) and TBM (IC50 = 28.9 ± 1.60μM). Notably, the inhibition efficiency of GLY is even comparable with the FDA approved AD drug, donepezil (DON). The larger size of GLY spans almost the full gorge of AChE ranging from catalytic active site (CAS) to the peripheral active site (PAS) with relatively strong binding affinity (6.0 x 105 M-1) and acts as a competitive inhibitor for AChE. On the other hand, while they show relatively weak binding ((2-6) x 104 M-1), both CPM and TBM act as noncompetitive binders. While these two drugs can bind to PAS, MD simulation results predict an alternative noncompetitive inhibition mechanism for CPM. These results open the possibility of repurposing the antidiabetic drugs, particularly GLY, in the treatment of AD. The consequential side effect of excess acetylcholine production, due to the administration of these drugs to AD-unaffected patients, can be rectified by using colloidal gold and silver nanofluids as potential AChE activity boosters.

Dysregulation of translation initiation factor 4E (eIF4E) activity occurs in various cancers. Mitogen-activated protein kinase (MAPK) interacting kinases 1 and 2 (MNK1 and MNK2) play a fundamental role in activation of eIF4E. Structure-activity relationship-driven expansion of a fragment hit led to discovery of dual MNK1 and MNK2 inhibitors based on a novel pyridine-benzamide scaffold. The compounds possess promising in vitro and in vivo pharmacokinetic profiles and show potent on target inhibition of eIF4E phosphorylation in cells.
