Novel 1,3-thiazolidin-4-one derivatives as promising anti-Candida agents endowed with anti-oxidant and chelating properties

Pursuing our recent outcomes regarding the antifungal activity of N-substituted 1,3-thiazolidin-4-ones, we synthesized thirty-six new derivatives introducing aliphatic, cycloaliphatic and heteroaromatic moieties at N1-hydrazine connected with C2 position of the thiazolidinone nucleus and functionalizing the lactam nitrogen with differently substituted (NO2, NH2, Cl and F) benzyl groups. These compounds were tested to evaluate their minimum inhibitory concentration (MIC) against several clinical Candida spp. with respect to topical and systemic reference drugs (clotrimazole, fluconazole, ketoconazole, miconazole, tioconazole, amphotericin B). Moreover, anti-oxidant properties were also evaluated by using different protocols including free radical scavenging (DPPH and ABTS), reducing power (CUPRAC and FRAP), metal chelating and phosphomolybdenum assays. Moreover, for the most active derivatives we assessed the toxicity (CC50) against Hep2 human cells in order to characterize them as multi-target agents for fungal infections.

Acid-Catalyzed Synthesis of Thiazolidin-4-ones

A two-steps synthesis of thiazolidin-4-ones, from -tetralone 6 or thiochroman-4-one 7, catalyzed by acids is described. The reactions of -tetralone 6 or thiochroman-4-one 7, with substituted thiosemicarbazides, under AcOH or heteropolyacid (HPAs) catalysis afford thiosemicarbazones 8 and 9 in excellent yields. Condensations of the previous compounds 8 and 9 with -bromoester, under sulfuric acid or heteropolyacid catalysis, yield the corresponding thiazolidin-4-ones 10 and 11.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.

Synthesis of thiazolidin-4-ones and thiazinan-4-ones from 1-(2-aminoethyl)pyrrolidine as acetylcholinesterase inhibitors

The present study describes the synthesis of a novel series of thiazolidin-4-one and thiazinan-4-one using 1-(2-aminoethyl)pyrrolidine as amine precursor. All compounds were synthesised by one-pot three component cyclocondensation reaction from the amine, a substituted benzaldehyde and a mercaptocarboxylic acid. The compounds were obtained in moderate to good yields and were identified and characterised by H-1, C-13?, 2?D NMR and GC/MS techniques. The compounds also were screened for their in vitro acetylcholinesterase (AChE) activity in hippocampus and cerebral cortex on Wistar rats. The six most potent compounds have been investigated for their cytotoxicity by cell viability assay of astrocyte primary culture, an important cell of central nervous system. We highlighted two compounds (6a and 6k) that had the lowest IC50 in hippocampus (5.20 and 4.46??M) and cerebral cortex (7.40 and 6.83??M). These preliminary and important results could be considered a starting point for the development of new AChE inhibitory agents.

Design, graph theoretical analysis, density functionality theories, Insilico modeling, synthesis, characterization and biological activities of novel thiazole fused quinazolinone derivatives

A series of 2-(2-substituted benzylidenehydrazinyl-2-oxopropyl)-3-(4-[4-oxo-2-phenylthiazolo din-3-yl]phenyl)quinazolin-4(3H)-one 7a-7l were synthesized and characterized by IR, H-1-NMR, C-13-NMR, mass spectroscopy and elemental analyses. In this present study, the density functionality theory was performed to identify drug stability. Further we introduced graph theoretical analysis by utilised Kyoto Encyclopedia of Genes and Genomes (KEGG) database and Cytoscape software to identify drug target. Based on the observed drug target insilico modeling was executed to know effective drug. The antiepileptic effects of title compounds were evaluated by using MES and subcutaneous pentylenetetrazole (scPTZ) test. Acute neurological toxicity of title compounds was studied by using standardized rotorod test. After 0.5 hr of period many of the compounds showed anticonvulsant activity at MES or scPTZ test. Comparison of the biological activity of test compounds with its chemical structures indicates that, compounds possessing electron donating group exhibited superior activity than the analogs having electron withdrawing moieties. Among the electron donating group tested, amino derivative exhibited good activity than rest of derivatives. From the study it was concluded that, the compound 7j was established as very potent compared with rest of the compounds and standard drugs subjected to biological studies. Thus the compound 2-(2-[4-aminobenzylidene]hydrazinyl-2-oxopropyl)-3-(4-[4-oxo-2-phenylthiazolidin-3-yl]phenyl) quinazolin-4(3H)-one (7j) came out as pilot derivative without any neurotoxicity with a wide spectrum of antiepileptic activity.

Utility of chloroacetonitrile in construction of some hitherto novel pyrazole and thiazole derivatives

2-(-Piperidin-1-yl) acetamide (2) was easily prepared by reacting chloroacetonitrile with piperidine. Furthermore, (2) was allowed to react with different aromatic aldehydes to afford novel arylidene derivatives (3a,b). Unexpectedly, 2-oxo-4-hydroxy-thiazole (5) was obtained instead of 2-(piperidin-1-yl-methylene) thiazolidin-4-one (4) when (2) was treated with mercaptoacetic acid under fusion conditions. Subsequent treatment of (5) with aromatic aldehydes and either malononitrile or cyanoacetamide (1:1:1 molar ratios) produced the hitherto unknown pyrano[2,3-d] thiazole derivatives (6a,b) and (7). Novel pyrazole derivatives (8a, b) and (9) were synthesized upon cyclocondensation of (2) with aromatic aldehydes and hydrazine hydrate. Unfortunately, attempts to prepare novel isoxazole derivatives by utilizing hydroxylamine instead of hydrazine hydrate following the previous procedure were failed. Surprisingly, the uncyclized products (10a,b) were obtained rather than 3-hydroxy-4-piperidinyl-isoxazole (11a,b). Upon refluxing thiosemicarbazide with (2) and aromatic aldehydes under the same conditions, pyrazolinone carbothioamides (12), (13) and (14a-c) were obtained.

The structures of the synthesized compounds (6a-g) and (7a-i) were elucidated by 1H-NMR spectroscopy. The molecular docking studies were performed for all the synthesized compounds against GlcN-6P using AutoDock-tools-1.5.6 and recorded the extent of H-bonding and binding affinities. The preselected compounds via molecular docking were further tested for in vitro antimicrobial activity against five bacterial strains (Escherichia coli, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa, Staphylococcus aureus) and two fungal strains (Candida albicans and Cryptococcus neoformans). The antimicrobial findings exhibited that the compounds possessed significant antimicrobial potential.

One-pot four-component synthesis of thiazolidin-2-imines using Cu-I/Zn-II dual catalysis: A new class of acetylcholinesterase inhibitors

An efficient one-pot four-component strategy involving aldehydes, amines, alkynes and isothiocyanates has been developed to access a novel series of thiazolidine-2-imines (5a-x). This process operates under the action of a cooperative catalysis composed of Cu(I) and Zn(II) delivering the desired five-membered heterocyclic compounds in good to excellent yields. Notably, this transformation avoids the use of pre-formed imines or propargylamines and proceeds via an intramolecular 5-exo-dig hydrothiolation reaction of the in situ formed propargyl thiourea. Furthermore, the biological application of these motifs was demonstrated in terms of their strong acetylcholinesterase (AChE) inhibitory activity where compound 5s was identified as the lead AChE inhibitor with an IC50, value of 0.0023 +/- 0.0002 mu M, 88-folds stronger inhibition than standard drug (neostigmine methyl sulphate; IC50, = 0.203 +/- 0.004 mu M). Molecular docking analysis reinforced the in vitro biological activity results revealing the formation of several useful interactions of the potent lead with amino acid residues in the active site of the enzyme.
