The design, synthesis, and: In vitro trypanocidal and leishmanicidal activities of 1,3-thiazole and 4-thiazolidinone ester derivatives

Chagas and leishmaniasis are both neglected tropical diseases, whose inefficient therapies have made them remain the cause for millions of deaths worldwide. Given this, we synthesized 27 novel 1,3-thiazoles and 4-thiazolidinones using bioisosteric and est

Assessment of Thiosemicarbazone-Containing Compounds as Potential Antileukemia Agents against P-gp Overexpressing Drug Resistant K562/A02 Cells

P-Glycoprotein (P-gp) overexpression is considered to be the leading cause of multidrug resistance (MDR) and failure of chemotherapy for leukemia. In this study, seventeen thiosemicarbazone-containing compounds were prepared and evaluated as potential ant

Facile synthesis of novel fluorescent thiazole coumarinyl compounds: Electrochemical, time resolve fluorescence, and solvatochromic study

In this study, Benzocoumarin-Thiazoles-Azomethine derivatives with bioactive scaffolds were synthesized and characterized. The present investigation is concerned with the multistep synthesis of thiazole coumarinyl derivatives (5a-k), which were accomplished from naphthaldehyde, ethyl acetoacetate, and thiosemicarbazide. The formation of newly synthesized derivatives was confirmed by 1H NMR and 13C NMR spectroscopic studies. Thiazole coumarinyl derivatives were subjected to UV-Visible studies in different solvents such as ethanol, ethyl acetate, and DMF for solvatochromic studies. The synthesized coumarinyl thiazole compounds showed absorption in the range of 332-390 nm. Electrochemical studies were performed in DMSO and redox behavior was offered by thiazoles. Fluorescence of coumarinyl thiazole compounds were examined in ethanol, ethyl acetate, and DMF to visualize the solvent effect on the emitting ability of compounds. Fluorescence spectra of coumarinyl thiazoles expressed a sharp emission in the range 436-550 nm.

Abstract—New 4,4'-(4,6-dimethoxy-1,3-phenylene)bis{2-[2-(substituted benzylidene)hydrazinyl]thiazole} derivatives (5a–5j) have been synthesized from the corresponding 1,1'-(4,6-dimethoxy-1,3-phenylene)bis(2,2- dibromoethanone) and substituted thiosemicarbazones by the conventional method and under microwave irradiation. Structures of the synthesized compounds were characterized by FT-IR, 1H, and 13C NMR and Mass spectra. The products were evaluated for their in vitro antibacterial activity against Gram-positive and Gramnegative stains. Some of the compounds 5b, 5f, 5h demonstrated high activity against B. subtilis (+ve), compound 5c exhibited high activity against E. coli (–ve) and P. aeruginosa (–ve) stains. Among the titled compounds also evaluated for their in vitro antimycobacterial activity, the product 5b demonstrated pronounced antimycobacterial activity against M. bovis stain.
