Environmentally Benign Deep Eutectic Solvent for Synthesis of 1,3-Thiazolidin-4-ones

This paper explores the versatility and effectiveness of Deep Eutectic Solvent (DES) as an efficient catalyst cum reaction media for the preparation of biologically important 1,3- thiazolidin-4-one derivatives. This methodology was objected to overcome the limitations of the previously reported methods such as the use of expensive and toxic solvents, long reaction time and low yield. This protocol is rapid, environmentally benign, with good to high yield of products. The DES media could be reused up to five times without any appreciable decrease in the yield.

New hydrazide-hydrazones and 1,3-thiazolidin-4-ones with 3-hydroxy-2-naphthoic moiety: Synthesis, in vitro and in vivo studies

In this research we synthesized, identified and evaluated new hydrazide-hydrazones (1-3) and 1,3-thiazolidin-4one derivatives (4-6) for in vitro and in vivo activity. New hydrazide-hydrazones (1-3) were obtained by the condensation reaction of 3-hydroxy-2-naphthoic acid hydrazide with appropriate aldehydes. Synthesized hydrazide-hydrazones (1-3) were subjected to cyclization reaction with mercaptoacetic acid which afforded with new 1,3-thiazolidin-4-one derivatives (4-6). Among 1,3-thiazolidin-4-one derivatives tested (4-6), compound 6 exhibited highest and most selective cytotoxicity towards human renal adenocarcinoma cells (769-P) and it did not affect the growth of normal cells (H9c2, GMK). Whereas its hydrazide-hydrazone (compound 3) showed significant antiproliferative activity against both tested human cancer cell lines: renal adenocarcinoma (769-P) and hepatocellular carcinoma (HepG2), however with less selectivity. The in vivo studies focused on the anti-nociceptive activity of newly synthesized 1,3-thiazolidin-4-one derivatives (4-6). The preliminary screening of novel compounds showed that 1,3-thiazolidin-4-one derivatives (4-6) are safe and not toxic against CNS of mice. Among tested derivatives one compound (6) displayed significant analgesic activity.

Synthesis and Biological Evaluation of New 4-Thiazolidinone Derivatives as Carbonic Anhydrase Inhibitors

Background: The catalytically active site of CA enzyme is Zn (II) bound hydroxide ion part which acts as a strong nucleophile (at neutral pH) on the CO2 molecule bound in a hydrophobic pocket nearby. We designed a series of thiazolidinone molecules which are able to approach the active side by way of hydrophobic part and may interact with the hydroxide and Zn (II) by ring opening of thiazolidinone. Methods: Thirteen novel aminoindane thiazolidinone derivatives, 2a-m were synthesized, characterized and their inhibitory effects on the activity of purified human carbonic anhydrase (hCA) I and II were evaluated. hCA I and II from human erythrocytes were purified by a simple one step procedure by using Sepharose 4B-L-tyrosine-sulphanilamide affinity column. Results: In vitro results showed that all compounds were inhibited by the CA izoenzymes activity. 2d was found to be most active compound IC50=6.75 mu M and 7.55 mu M for hCA I and hCA II, respectively. Conclusion: New aminoindane thiazolidinone derivatives have been designed, synthesized and evaluated as Carbonic Anhydrase Inhibitors. According to the results, these compounds can be conceivable as new candidates for the treatment of the illness that CAI and CAII enzyme inhibitors are used in the treatment.

Synthesis of pentacyclic iminosugars with constrained butterfly-like conformation and their HIV-RT inhibitory activity

Novel pentacyclic iminosugars 1 and 2 with the constrained butterfly-like conformation were first synthesized by the key intramolecular click reaction from the tricyclic iminosugars fused benzo[e][1,3] thiazin-4-one 3 and 4. The pentacyclic iminosugar was constructed by fusing both benzo[e][1,3] thiazin-4-one and triazolo[5,1-c][1,4] oxazepine scaffolds. Their structures were determined by their H-1, C-13 NMR, and HRMS (ESI) spectra and X-ray. The pentacyclic iminosugars 1(a-c), 2(a-b) and their corresponding protected precursors 13(a-c) and 14(a-b) were examined for their HIV reverse transcriptase (RT) inhibitory activities. The result showed that all compounds could effectively inhibit RT activity. Among them, compound 13c was the best one with the IC50 value of RT inhibitory activity of 0.69 mu M. Structure-activity relationship analysis suggested that the improvement of the hydrophilicity of the pentacycles was of benefit to their anti-HIV RT activity. (C) 2017 Elsevier Ltd.

A convenient and metal-free DMAP-catalyzed domino reaction of isatins, arylamines and hydroximoyl chlorides has been developed to achieve 1,3-dipolar cycloaddition of imines into aryl nitrile oxides at ambient temperature. In this one-pot transformation, a 1,2,4-oxadiazole skeleton was efficiently formed. This methodology needs no extra additives and features wide substrate scope, good functional group tolerance and mild reaction conditions. A plausible mechanism for this process was proposed. Moreover, the antibacterial activities of the products were evaluated towards Staphylococcus epidermidis, Staphylococcus aureus, Escherichia coli and Klebsiella pneumoniae using the Broth microdilution method.

Spectrophotometric Determination of Ru(IV) Using 5-Hydroxyimino-4-imino-1,3-thiazolidin-2-one as a Novel Analytical Reagent

The interaction of Ru(IV) ions with a novel analytical reagent – 5-hydroxyimino-4-imino-1,3-thiazolidin-2-one, by spectrophotometric method was investigated. The complex is formed at pH 5.0 in acetate buffer medium after heating in the boiling water bath (similar to 371 K) for 25 min. The complex has maximum absorption at 350 nm and is stable for 24 h. Beer’s law is valid over the concentration range of 0.5-6.1 mu g mL(-1) for Ru(IV). The molar absorptivity at lambda= 350 nm is 6.21 x 10(3) L mol(-1) cm(-1). The limit of detection of this method is 0.2 mu g mL(-1). The interfering effect of various cations and anions on the spectrophotometric determination of the Ru(IV) were investigated. The proposed method was successfully applied to the determination of Ru(IV) in alloys.
