Desulfurization-oxygenation of chiral 1,3-thiazolidine-2-thiones and 1,3-oxazolidine-2-thiones using propylene oxide and microwave irradiation

An efficient method for the desulfurization-oxygenation of 1,3-thiazolidine-2-thiones and 1,3-oxazolidine-2-thiones using propylene oxide and employing microwave irradiation is described. This strategy of oxygenation of the thiocarbonyl group provides an attractive methodology to prepare chiral 1,3-thiazolidin-2-ones and 1,3-oxazolidin-2-ones from the corresponding precursors in good yields.

SLC26A3 inhibitor identified in small molecule screen blocks colonic fluid absorption and reduces constipation

SLC26A3 (downregulated in adenoma; DRA) is a Cl-/anion exchanger expressed in the luminal membrane of intestinal epithelial cells, where it facilitates electroneutral NaCl absorption. SLC26A3 loss of function in humans or mice causes chloride-losing diarrhea. Here, we identified slc26a3 inhibitors in a screen of 50,000 synthetic small molecules done in Fischer rat thyroid (FRT) cells coexpressing slc26a3 and a genetically encoded halide sensor. Structure-Activity relationship studies were done on the most potent inhibitor classes identified in the screen: 4,8-dimethylcoumarins and acetamide-Thioimidazoles. The dimethylcoumarin DRAinh-A250 fully and reversibly inhibited slc26a3-mediated Cl- exchange with HCO3 -, I-, and thiocyanate (SCN-), with an IC50 of ?0.2 muM. DRAinh-A250 did not inhibit the homologous anion exchangers slc26a4 (pendrin) or slc26a6 (PAT-1), nor did it alter activity of other related proteins or intestinal ion channels. In mice, intraluminal DRAinh-A250 blocked fluid absorption in closed colonic loops but not in jejunal loops, while the NHE3 (SLC9A3) inhibitor tenapanor blocked absorption only in the jejunum. Oral DRAinh-A250 and tenapanor comparably reduced signs of constipation in loperamide-Treated mice, with additive effects found on coadministration. DRAinh-A250 was also effective in loperamidetreated cystic fibrosis mice. These studies support a major role of slc26a3 in colonic fluid absorption and suggest the therapeutic utility of SLC26A3 inhibition in constipation.

Synthesis and biological evaluation of some new benzofuran derivatives

5-Chloro-3-methyl-2-benzofuran carbohydrazide (4) upon treatment with potassium isothiocynate in presence of hydrochloric acid in water gave 5-chloro-3-methylbenzofuran-2-carbo-N-thiosemicarbazide (5). The cyclisation of 5-chloro-3-methylbenzofuran-2-carbo-N-thiosemicarbazide (5) under different reaction conditions offered 1,3,4-oxadiazole, 1,3,4-thiadiazole, 1,2,4-triazole, thiazolidinone and thiopyrimidinone. The structures of these compounds were established on the basis of spectral data. Some of these compounds exhibited good antimicrobial activity.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.category: thiazolidine, you can also check out more blogs about2682-49-7

Catalytic, enantioselective N-acylation of lactams and thiolactams using amidine-based catalysts

In contrast to alcohols and amines, racemic lactams and thiolactams cannot be resolved directly via enzymatic acylation or classical resolution. Asymmetric N-acylation promoted by amidine-based catalysts, particularly Cl-PIQ 2 and BTM 3, provides a convenient method for the kinetic resolution of these valuable compounds and often achieves excellent levels of enantioselectivity in this process. Density functional theory calculations indicate that the reaction occurs via N-acylation of the lactim tautomer and that cation-pi interactions play a key role in the chiral recognition of lactam substrates.

Diastereoselective additions of titanium enolates from N-glycolyl thiazolidinethiones to acetals

The stereochemical outcome of the Lewis acid-mediated glycolate addition of the titanium enolates from protected N-hydroxyacetyl-4-isopropyl-1,3- thiazolidine-2-thiones to dimethyl and dibenzyl acetals depends on the hydroxyl protecting group. Particularly, the pivaloyl protected glycolate derivative provides the reluctant anti adducts in high yields and diastereomeric ratios, which can be isolated and further converted in enantiomerically pure form to beta-methoxy or beta-benzyloxy alpha-pivaloyloxy carbonyl fragments in a straightforward manner.

The role of treatment with high-dose corticosteroids in severe leptospirosis with pulmonary complications

Objective: To investigate the effectiveness of high-dose corticosteroids in patients with severe leptospirosis, especially in reducing morbidity and mortality rates. Methods: Literature searches were conducted using PubMed and SCOPUS. One systematic review and one systematic review with meta-analysis were selected from three chosen studies. Results: The systematic review from Rodrigo et al. only included qualitative synthesis from four interventional studies. Early administration of methylprednisolone can be beneficial; however, low number and poor methodological quality of the studies question the validity of this review. Duggal et al. stated that there was no significant difference in the therapeutic effects of early high-dose corticosteroids (P ? 0.05; 95% CI: 0.81?1.37), early low-dose corticosteroids (P ? 0.05; 95% CI: 0.3?1.03), and late low-dose corticosteroids (P ? 0.05; 95% CI: 0.11?2.52). Limited number of studies and high statistical heterogeneity, however, are major drawbacks for this review. Conclusion: Evidence about the role of high-dose corticosteroids in severe leptospirosis patients with pulmonary complications, especially their benefits, is still limited. Additional randomized, controlled trials with adequate statistical power still need to be conducted.

1, 3-thiazolidin-4-one derivatives bearing pyrimidine moieties: Design, computational studies, synthesis, characterization, antimicrobial, MTT assessment and molecular docking assessment

1, 3-thiazolidin-4-one derivatives bearing 5,6-dihydrothieno[2,3-d]pyrimidine moiety (1-10) were designed and assessed for the level of bioactivity, computationally. Computational findings revealed that compounds 1-8 were exhibiting very good bioactivity score as GPCR ligand, and lying in the zone for active drug molecule, while compounds 9-10, were lying under the zone of moderately active drug molecule. The bioactive compounds (1-10) were then synthesized, characterized and assessed for antimicrobial potential and percent viability of cells. All the compounds (1-10) were found to have very good antimicrobial potential, although some of the members of the series possessed better antimicrobial potential than the reference drug ?Ciprofloxacin?. In Addition, molecular docking assessment was carried out for all the synthesized compounds against the protein GlcN-6-P-synthase to embed both in-silico and in vitro results. The findings revealed that most of the compounds were found to exhibit significant hydrogen bonding to the residues of GlcN-6-P-synthase with a binding affinity -6.9 to -5.3 Kcal/mole. The compounds were also tested for percent viability of cells by MTT assay, and the results revealed that ? 90 % viability of the cells was found @ 3.12 muM and ? 70 @ 100 muM.

Design, synthesis, anticancer screening, docking studies and in silico ADME prediction of some beta-carboline derivatives

Background: Medicinal interest has focused on beta-carbolines as anticancer agents. Methodology/Results: Several beta-carbolines were designed, synthesized and evaluated for their cytotoxic activity against MCF-7 and A-549 cancer cell lines using MTT assay. Compounds 13a, 13c, 13d and 20a were the most promising showing high selectivity indices. Compounds 13c and 20a showed potent inhibition of topoisomerase (topo-I) and kinesin spindle protein (KSP/Eg5 ATPase) which was confirmed by their docking results into the active site of both enzymes. In silico physicochemical calculations predicted that compounds 13a, 13d and 20a obeyed Lipinski’s rule of five. Conclusion: Compounds 13c and 20a are multitarget anticancer leads that act as potent inhibitors for both topo-I and/or KSP ATPase.

First catalytic enantioselective synthesis of P-stereogenic phosphoramides via kinetic resolution promoted by a chiral bicyclic imidazole nucleophilic catalyst

A novel method toward the synthesis of P-stereogenic organophosphorus compounds via kinetic resolution by a catalytic asymmetric phosphorylation through P-N bond formation has been developed. Using a chiral bicyclic imidazole nucleophilic catalyst, chiral phosphoramide compounds were prepared in high conversions and with moderate enantioselectivity. This is also the first example of the catalytic asymmetric synthesis of chiral phosphoramide compounds.
