Synthesis and antimicrobial activity of benzimidazolyl oxazolyl thiazolidin-4-ones and azetidin-2-ones

A new series of 3-[4-(1H-benzo[d] imidazol-2-yl) oxazol-2-yl]-2-thiazolidin-4-ones 4 and 1-[4-(1H-benzo[d] imidazol-2-yl) oxazol-2-yl)-3-azetidin-2-ones 5 have been prepared from 2-acetyl benzimidazole 1. Compound 1 on treatment with urea in presence of 12 furnishes 4-(1H-benzo[d] imidazol-2-yl) oxazol-2-amine 2, which on condensation with aromatic aldehydes affords the corresponding Schiff bases 3. Cyclocondensation of 3 with thioglycollic acid produces the benzimidazolyl oxazolyl thiazolidin-4-ones 4, whereas, reaction of 3 with chloroacetyl chloride in presence of triethyl amine furnishes benzimidazolyl oxazolyl azetidin-2-ones 5. The structures of the newly synthesized compounds 3-5 have been elucidated on the basis of spectral (IR, H-1 and C-13 NMR and MS) and analytical data. The title compounds 4 and 5 have been screened for their antimicrobial activity. Some of the compounds exhibit promising antimicrobial activity.

Catalyst-, solvent- and desiccant-free three-component synthesis of novel C-2, N-3 disubstituted thiazolidin-4-ones

Herein it is provided an efficient, environmentally friendly and one-pot procedure for the synthesis of a library of new and diversely substituted 1,3-thiazolidin-4-ones in short reaction times and good yields through a solvent-, catalyst- and desiccant-free three-component process. Reactions proceeded by treatment of primary benzyl(aryl)amines with aromatic aldehydes (and ketones) and 2-mercaptoacetic acid acting as both reagent and self-catalyst. All reactions were performed in sand bath instead of the commonly used oil bath avoiding the generation of undesired volatile materials proceeding of the thermal decomposition of the oils. IR, Mass and NMR experiments as well as X-ray diffraction confirmed structures of the obtained products. (C) 2016 The Authors.

Genetic and small molecule inhibition of arylamine N-acetyltransferase 1 reduces anchorage-independent growth in human breast cancer cell line MDA-MB-231

Arylamine N-acetyltransferase 1 (NAT1) expression is reported to affect proliferation, invasiveness, and growth of cancer cells. MDA-MB-231 breast cancer cells were engineered such that NAT1 expression was elevated or suppressed, or treated with a small molecule inhibitor of NAT1. The MDA-MB-231 human breast cancer cell lines were engineered with a scrambled shRNA, a NAT1 specific shRNA or a NAT1 overexpression cassette stably integrated into a single flippase recognition target (FRT) site facilitating incorporation of these different genetic elements into the same genomic location. NAT1-specific shRNA reduced NAT1 activity in vitro by 39%, increased endogenous acetyl coenzyme A levels by 35%, and reduced anchorage-independent growth (sevenfold) without significant effects on cell morphology, growth rates, anchorage-dependent colony formation, or invasiveness compared to the scrambled shRNA cell line. Despite 12-fold overexpression of NAT1 activity in the NAT1 overexpression cassette transfected MDA-MB-231 cell line, doubling time, anchorage-dependent cell growth, anchorage-independent cell growth, and relative invasiveness were not changed significantly when compared to the scrambled shRNA cell line. A small molecule (5E)-[5-(4-hydroxy-3,5-diiodobenzylidene)-2-thioxo-1,3-thiazolidin-4-one (5-HDST) was 25-fold more selective towards the inhibition of recombinant human NAT1 than N-acetyltransferase 2. Incubation of MDA-MB-231 cell line with 5-HDST resulted in 60% reduction in NAT1 activity and significant decreases in cell growth, anchorage-dependent growth, and anchorage-independent growth. In summary, inhibition of NAT1 activity by either shRNA or 5-HDST reduced anchorage-independent growth in the MDA-MB-231 human breast cancer cell line. These findings suggest that human NAT1 could serve as a target for the prevention and/or treatment of breast cancer.

Anticancer potential of new steroidal thiazolidin-4-one derivatives. Mechanisms of cytotoxic action and effects on angiogenesis in vitro

The synthesis and cytotoxic activities determination of new steroidal mono- and bis(thiazolidin-4-ones) 4a-f and 5a-f have been performed. Their anticancer action was also evaluated in comparison to previously synthesized and reported corresponding steroidal thiosemicarbazones. All compounds were obtained as stereoisomeric mixtures with different configuration (E or Z) in the hydrazone moiety at the C-3 position. After several consecutive crystallizations diastereomerically pure major (5)-isomers of mono-thiazolidin-4-ones were isolated. The structure and stereochemistry of 2,4-thiazolidinedione,2-[(17-oxoandrost-4-en-3-ylidene)hydrazone] were confirmed by X-ray analysis. A pathway for the formation of thiazolidin-4-one ring was proposed. The steroid thiazolidinone derivatives examined in this study exerted selective concentration-dependent cytotoxic activities on six tested malignant cell lines. Ten out of twelve examined compounds exhibited strong cytotoxic effects on K562 cells (IC50 values from 8.5 mu M to 14.9 mu M), eight on HeLa cells (IC50 values ranging from 8.9 mu M to 15.1 mu M) while against MDA-MB-361 cells six compouds exerted similar or even higher cytotoxic action (IC50 values from 12.7 mu M to 25.6 mu M) than cisplatin (21.5 mu M) which served as a positive control. Eight of these ten compounds showed high selectivity in the cytotoxic action against HeLa and K562 cancer cell lines when compared with normal human fibroblasts MRC-5 and normal human PBMC. The study of mechanisms of the anticancer activity of the two selected compounds, mono- and bis(thiazolidin-4-one) derivatives of 19-norandrost-4-ene-3,17-dione 4a and 5a, revealed that both of these compounds induced apoptosis in HeLa cells through extrinsic and intrinsic signalling pathways. Treatment of EA.hy926 cells with sub-toxic concentrations of these compounds led to the inhibition of cell connecting and sprouting, and tube formation. The synthesized compounds exhibited poor antioxidant activity.

Thiol-Yne Coupling of Propargylamine under Solvent-Free Conditions by Bond Anion Relay Chemistry: An Efficient Synthesis of Thiazolidin-2-ylideneamine

Thiol-yne coupling of propargylamine with isothiocyanate has been developed under metal- and solvent-free conditions. The addition of propargylamine to isothiocyanate gives propargylthiourea. This intermediate in situ undergoes intramolecular 5-exo-dig cyclization to give thiazolidin-2-ylideneamine. A through-bond anion relay reaction occurs by attack of the sulfur (not the nitrogen) atom on the alkyne in a highly regioselective manner at ambient temperature. Wide varieties of thiazolidin-2-ylideneamine derivatives were formed in excellent yields.

Related Products of 85-42-7, Consequently, the presence of a catalyst will permit a system to reach equilibrium more quickly, but it has no effect on the position of the equilibrium as reflected in the value of its equilibrium constant.I hope my blog about 85-42-7 is helpful to your research.

Synthesis, characterization, biological, and molecular docking assessment of bioactive 1,3-thiazolidin-4-ones fused with 1-(pyrimidin-2-yl)-1H-imidazol-4-yl) moieties

A series of fifteen computationally bioactive 1,3-thiazolidin-4-ones fused with 1-(pyrimidin-2-yl)-1H-imidazol-4-yl moieties (1-15) were synthetically prepared and assessed for antimicrobial potential against the four strains (two gram-positive and two gram-negative). The structures were supported by spectroscopic methods like FT-IR, NMR (H-1 & C-13), mass spectroscopy, etc. The antimicrobial efficacy of the prepared compounds was achieved by the method of disk diffusion, and the effects were recorded in terms of zone of inhibition and minimum inhibitory concentration. Dimethyl sulfoxide and ciprofloxacin were used as negative and positive controls. The results stated that two compounds (7 and 10) were reported to exhibit better antimicrobial activity than the standard drug ciprofloxacin, while the other members represented considerable potential. Molecular docking was also performed to support the in vitro antimicrobial results, to understand the extent of H-bonding and the binding affinities of the compounds (1-15), with the amino acid residues of the receptor GlcN-6P and, represented significant H-bonding. An MTT assay was also carried out to see the toxic effects of the prepared compounds and posed that the compounds were less toxic toward the HepG2 cells. [GRAPHICS] .
