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.

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.

Synthesis and antimicrobial evaluation of new halogenated 1,3-Thiazolidin-4-ones

The ongoing prevalence of multidrug-resistant bacterial pathogens requires the development of new effective antibacterial agents. In this study, two series of halogenated 1,3-thiazolidin-4-ones were synthesized and characterized. All the synthesized thiazolidinone derivatives were evaluated for their antimicrobial activity. Biological screening of the tested compounds revealed the antibacterial activity of the chlorinated thiazolidinones 4a, 4b and 4c against Escherichia coli TolC-mutant, with MIC values of 16 mu g/mL. A combination of a sub-inhibitory concentration of colistin (0.25 x MIC) with compounds 4a, 4b or 4c showed antibacterial activity against different Gram-negative bacteria (MICs = 4-16 mu g/mL). Interestingly, compounds 4a, 4b and 4c were not cytotoxic to murine fibroblasts and Caco-2 cells. The chlorinated thiazolidinone derivative 16d demonstrated a bacteriostatic activity against a panel of pathogenic Gram-positive bacteria, including clinical isolates of methicillin and vancomycin-resistant Staphylococcus aureus, Listeria monocytogenes and multidrug-resistant Staphylococcus epidermidis (MICs = 8 – 64 mu g/mL), with no cytotoxicity against both Caco-2 and L929 cells. Compound 16d was superior to vancomycin in disruption of the pre-formed MRSA biofilm. Furthermore, the three fluorinated thiazolidinone derivatives 26c, 30c and 33c showed a hindrance to hemolysin activity, without cytotoxicity against L929 cells.

Anti-Candida activity and cytotoxicity of a large library of new N-substituted-1,3-thiazolidin-4-one derivatives

On the basis of the recent findings about the biological properties of thiazolidinones and taking into account the encouraging results about the antifungal activity of some (thiazol-2-yl)hydrazines, new N-substituted heterocyclic derivatives were designed combining the thiazolidinone nucleus with the hydrazonic portion. In details, 1,3-thiazolidin-4-ones bearing (cyclo)aliphatic or (hetero)aromatic moieties linked to the N1-hydrazine at C2 were synthesized and classified into three series according to the aromatic or bicyclic rings connected to the lactam nitrogen of the thiazolidinone. These molecules were assayed for their anti-Candida effects in reference to the biological activity of the conventional topic (clotrimazole, miconazole, tioconazole) and systemic drugs (fluconazole, ketoconazole, amphotericin B). Finally, we investigated the selectivity against fungal cells by testing the compounds endowed with the best MICs on Hep2 cells in order to assess their cell toxicity (CC50) and we noticed that two derivatives were less cytotoxic than the reference drug clotrimazole. Moreover, a preliminary molecular modelling approach has been performed against lanosterol 14-alpha demethylase (CYP51A1) to rationalize the activity of the tested compounds and to specify the target protein or enzyme.

Design, Synthesis, Molecular Docking of Novel Substituted Pyrimidinone Derivatives as Anticancer Agents

Novel derivatives of pyrimidinone ring carrying some five-membered heterocycles had been designed and prepared. 1,3-Thiazolidin-4-one derivative 7 was prepared by the reaction of 1,2,3,4-tetrahydro-4-(4-hydroxyphenyl)-6-methyl-N ‘-((naphthalen-4-yl)methylene)-2-oxopyrimidine-5-carbohydrazide 6 with thioglycolic acid. Reacting the hydrazide 5 with benzoyl chloride gave compound 8 which cyclized to 1,3,4-oxadiazole 9 by the use of phosphorus pentoxide. Moreover, the pyrazole derivative 10 was obtained from reacting compound 5 with ethyl acetoacetate. Furthermore, the reaction of the hydrazide 5 with phenyl isothiocyanates produced the carbothioamide 11 which refluxed with hydrazonoyl chloride to yield 1,3,4-thiadiazole derivative 14. In addition, 1, 2,4-triazole derivative 16 was prepared via reacting the carbothioamide 11 with sodium hydroxide followed by methylation with methyl iodide. The structures of the newly prepared heterocyclic compounds were determined by spectral and elemental analysis. The cytotoxic activity of the target compounds (7, 9, 10, 14, and 16) were estimated in vitro against PC-3 (prostate adenocarcinoma), human HepG-2 (liver carcinoma), and HCT116 (colorectal carcinoma) cell lines using MTT assay. All the tested compounds appeared high level of inhibition against PC-3 and HCT116 cell lines, while appeared weak inhibitory action against HepG-2 cell lines, especially, the thiadiazole derivative 14. Furthermore, docking study had been carried out on the targets 7, 9, 10, 14, and 16 within EGFR as a prediction for the anticancer activity. All the docked compounds showed good fitting with EGFR recording docking scores range (-27.99 to -19.01).
