A series of sixteen novel thiazolidinone derivatives were synthesized from the efficient one-pot reaction of 2-(piperidin-1-yl)ethylamine, arenealdehydes and mercaptoacetic acid in good yields. Identification and characterization of products were achieved by NMR and GC MS techniques. The in vitro antifungal activities of all synthesized compounds were evaluated against seven fungi: Candida albicans, Candida parapsilosis, Candida guilliermondii, Cryptococcus laurentii, Geotrichum sp, Trichosporon asahii and Rhodotorula sp. The results are expressed as the Minimum Inhibitory Concentration (MIC) and Minimum Fungicidal Concentration (MFC) and the best results were found against the Rhodotorula sp yeast. Two thiazolidinones (4h and 4l), MIC and MFC (16.5 mu g/mL) proved to be 1.6 times more active than fluconazole and four of them (4b, 4e, 4g and 4k (MIC and MFC 25 mu g/mL)) showed similar activity of standard drug to Rhodotorula sp. In addition, the cytotoxicity of thiazolidinones 4a-p was evaluated on cultured Vero cells and most of them displayed low toxicity (above 98 mu g/mL). These preliminary and important results could be considered a starting point for the development of new antifungal agents. (C)2013 Elsevier Masson SAS. All rights reserved.
