  Synthesis of Some 2-(3-Alkyl/aryl-5-trifluoromethylpyrazol-1-yl)-4-(coumarin-3-yl)thiazoles as Novel Antibacterial Agents

  摘要：

  Herein, we describe a one-pot synthesis of some novel 2-(3-alkyl/aryl-5-trifluoromethylpyrazol-1-yl)-4-(coumarin-3-yl)thiazoles (6) involving the reaction of 3-alkyl/aryl-5-hydroxy-5-trifluoromethyl-4,5-dihydropyrazole-1-thiocarboxamides (3) with 3-bromoacetylcoumarins (5) in the presence of sodium carbonate in ethanol. Reaction of 3 with 5 in the absence of sodium carbonate, however, resulted in the formation of 2-(3-alkyl/aryl-5-hydroxy-5-trifluoromethyl-4,5-dihydropyrazol-1-yl)-4-(coumarin-3-yl)thiazoles, which were subsequently dehydrated to 6 by refluxing in ethanol in the presence of sodium carbonate. The structure of the synthesized compounds (6) was confirmed by infrared (IR), mass, H-1 NMR, and C-13 NMR spectra and elemental analysis data. Newly synthesized compounds (6) showed moderate to good activity against Gram-positive bacteria.

  Abstract: Our primary research objective is to create and formulate small ring heterocycles with enhanced biological efficacy. Amide functionalized trifluoromethyl thieno[2,3-b]pyridine derivatives as a series were prepared starting from reaction between 1,3 di-ketone and thiocyanoacetamide and obtained pyridine 3. Compound 3 reacts with bromoethyl acetate and obtained compound 4, further compound 4 on reaction with diverse substituted aromatic and aliphatic amines to get amide derivatives 5a-d, 6a-d and 7a-h. All the final compounds evaluated for anti cancer activity against four human cancer cell lines such as ‘HeLa - Cervical cancer (CCL-2); COLO 205- Colon cancer (CCL- 222); HepG2 - Liver cancer (HB-8065); MCF7 - Breast cancer (HTB-22)’ and promising compounds 7d, 7e and 7f have been identified. For compounds 7d, 7e and 7f molecular docking interactions have been identified.
