2-(4-氯苯基)-噻唑-4-羧酸乙酯 | ethyl 2-(4-chlorophenyl)thiazole-4-carboxylate | 61786-00-3 | C12H10ClNO2S | 267.736 |
A series of isatin-3-ylidene (6a-i) and arylthiazolyl-1,3,4-oxadiazole-2-thione derivatives 7a-i derived from arylthiazolyl carbohydrazide analogs 4a-i were synthesized. Analogously, coupling of 4f with various amino acid methyl esters in the presence of HOBt/DCC reagents afforded the carboxamide derivatives 9a-d. The newly synthesized compounds were assayed against HIV-1 and HIV-2 in MT-4 cells. All compounds are inactive, except compounds 9b and 9c which showed inhibition of HIV-1 with EC50 = 2:34 μg mL-1, and 1.12 μg mL-1 with therapeutic indexes (SI) of 9 and <1, respectively.
