Synthesis and bioactivity of N-tert-butyl-N′-acyl-5-methyl-1,2,3-thiadiazole-4-carbohydrazides
摘要:
A series of novel N-tert-butyl-N'-acyl-5-methyl-1,2,3-thiadiazole-4-carbohyclrazides were designed and synthesized. Their structures were characterized by melting points, H-1 NMR, IR, ESI-MS, and elemental analysis. The bioassay tests indicated that compound 7o exhibited excellent direct anti-TMV activity and induction activity in viva at 50 mu g/mL, which was better than that of Ninamycin and tiadinial. Our studies indicated that 1,2,3-thiadiazole was an active substructure for novel pesticide development. (C) 2012 Zhi Jin Fan. Published by Elsevier B.V. on behalf of Chinese Chemical Society.
