Alpha-amylase and urease enzyme over expression endorses various complications like rheumatoid arthritis, urinary tract infection, colon cancer, metabolic disorder, cardiovascular risk, and chronic kidney disease. To overcome these complications, we have synthesized new arylhydrazide bearing Schiff bases/thiazolidinone analogues as alpha-amylase and urease inhibitors. The analogues 1a-r were evaluated for alpha-amylase inhibitory potential. All analogues were found active and show IC50 value ranging between 0.8 ± 0.05 and 12.50 ± 0.5 muM as compare to standard acarbose (IC50 = 1.70 ± 0.10 muM). Among the synthesized analogs, compound 1j, 1r, 1k, 1e, 1b and 1f having IC50 values 0.8 ± 0.05, 0.9 ± 0.05, 1.00 ± 0.05, 1.10 ± 0.10, 1.20 ± 0.10 and 1.30 ± 0.10 muM respectively showed an excellent inhibitory potential. Analogs 2a-o were evaluated against urease activity. All analogues were found active and show IC50 value ranging between 4.10 ± 0.02 and 38.20 ± 1.10 muM as compare to standard thiourea (IC50 = 21.40 ± 0.21 muM). Among the synthesized analogs, compound 2k, 2a, 2h, 2j, 2f, 2e, 2g, 2b and 2l having IC50 values 4.10 ± 0.02, 4.60 ± 0.02, 4.70 ± 0.03, 5.40 ± 0.02, 6.70 ± 0.05, 8.30 ± 0.3, 11.20 ± 0.04, 16.90 ± 0.8 and 19.80 ± 0.60 muM respectively showed an excellent inhibitory potential. All compounds were characterized through 1H, 13C NMR and HR-EIMS analysis. Structure activity relationship of the synthesized analogs were recognized and confirmed through molecular docking studies.

The development of new antimalarial compounds remains a pivotal part of the strategy for malaria elimination. Recent large-scale phenotypic screens have provided a wealth of potential starting points for hit-to-lead campaigns. One such public set is explored, employing an open source research mechanism in which all data and ideas were shared in real time, anyone was able to participate, and patents were not sought. One chemical subseries was found to exhibit oral activity but contained a labile ester that could not be replaced without loss of activity, and the original hit exhibited remarkable sensitivity to minor structural change. A second subseries displayed high potency, including activity within gametocyte and liver stage assays, but at the cost of low solubility. As an open source research project, unexplored avenues are clearly identified and may be explored further by the community; new findings may be cumulatively added to the present work.

New heterocyclic compounds are of major importance because of growing problem of bacteria and fungi resistance and antimicrobial thiazolidinone have been gaining a lot of interest. A series of Thiazolidine-4-ones derivatives as antimicrobial agent were synthesized and screened for antibacterial activity against S. aureus, E. coli and P. vulgaris and antifungal activity against A. fumigatus, C. albicans and C. albicans ATCC. The structure of the newly synthesised compounds have been confirmed from elemental analysis, IR and 1HNMR data.

The biggest and most multifaceted class of organic compounds includes heterocyclic compounds. Currently, several heterocyclic compounds are iden-tified, and persistently gratefulness to tremendous synthetic work and synthetic usefulness, the number is increasing exponentially. In most fields of science, including medicinal, pharmaceutical, and agro-chemistry, heterocyclic compounds have a function, and biochemistry is also another area. In this research article, the green approach is administered for achieving the nitrogen, oxygen and sulphur centered five-membered heterocyclic derivatives. By taking the whole thing in to account of hetero-chemistry, the moderately effective analog for gram-positive and gram-negative bacterial strains was shown for the five-membered heterocyclic compound series of N-substituted iminothiazodine-4-one and N-(benzylideneamino)thiazol-4(5H). Throughout the synthesized series of the compound 6c revealed very much active potent against the gram-negative Escherichia coli bacterial strain and the compound 6b point out moderately active against the gram-positive Bacillus subtilis bacteria strains in accordance with the standard drug. The 5a and 6a compounds showed very strong activity against the fungal strain of Candida albicans and 6b as well as 6c were more active and highly potent than the standard drugs against Aspergillus niger species. In the view of this research drive states that all the synthesized compounds might be used for the development for further heterocyclic entities.

A major challenge in the treatment of cancer is multidrug resistance (MDR) that develops during chemotherapy. Here we demonstrate that tiopronin (1), a thiol-substituted N-propanoylglycine derivative, was selectively toxic to a series of cell lines expressing the drug efflux pump P-glycoprotein (P-gp, ABCB1) and MRP1 (ABCC1). Treatment of MDR cells with 1 led to instability of the ABCB1 mRNA and consequently a reduction in P-gp protein, despite functional assays demonstrating that tiopronin does not interact with P-gp. Long-term exposure of P-gp-expressing cells to 1 sensitized them to doxorubicin and paclitaxel, both P-gp substrates. Treatment of MRP1-overexpressing cells with tiopronin led to a significant reduction in MRP1 protein. Synthesis and screening of analogues of tiopronin demonstrated that the thiol functional group was essential for collateral sensitivity while substitution of the amino acid backbone altered but did not destroy specificity, pointing to future development of targeted analogues.

The effective action of endothelium-derived nitric oxide (EDNO) is impaired in patients with atherosclerosis. This impairment has been attributed in part to increased vascular oxidative stress. EDNO action is improved by administration of ascorbic acid, a water-soluble antioxidant. Ascorbic acid is a potent free-radical scavenger in plasma, and also regulates intracellular redox state in part by sparing cellular glutathione. We specifically investigated the role of intracellular redox state in EDNO action by examining the effect of L-2-oxo-4-thiazolidine carboxylate (OTC) on EDNO-dependent, flow-mediated dilation in a randomized double-blind placebo- controlled study of patients with angiographically proven coronary artery disease. OTC augments intracellular glutathione by providing substrate cysteine for glutathione synthesis. Brachial artery flow-mediated dilation was examined with high-resolution ultrasound before and after oral administration of 4.5 g of OTC or placebo in 48 subjects with angiographically documented coronary artery disease. Placebo treatment produced no change in flow-mediated dilation (7.0 ± 3.9% vs. 7.2 ± 3.7%), whereas OTC treatment was associated with a significant improvement in flow- mediated dilation (6.6 ± 4.4% vs. 11.0 ± 6.3%; P = 0.005). OTC had no effect on arterial dilation to nitroglycerin, systemic blood pressure, heart rate, or reactive hyperemia. These data suggest that augmenting cellular glutathione levels improves EDNO action in human atherosclerosis. Cellular redox state may be an important regulator of EDNO action, and is a potential target for therapy in patients with coronary artery disease.
