  New series of isoniazid hydrazones linked with electron-withdrawing substituents

  摘要：

  A series of new isoniazid hydrazones was synthesized by two procedures. In the first isoniazid was activated with diethoxymethyl acetate and condensed with the appropriate anilines. Alternatively, substituted anilines were activated by diethoxymethyl acetate and subsequently condensed with isoniazid. NMR study confirmed that both synthetic approaches gave the same tautomer. All compounds were screened for in vitro antimycobacterial activity. Most of them exhibited the same activity against Mycobacterium tuberculosis (MIC 1 mu mol L-1) as isoniazid (INH), better activity against Mycobacterium kansasii 325/80 (MIC 0.125-0.250 mu mol L-1), high value of selectivity index (SI) and IC50 between 0.0218 and 0.326 mmol L-1. Compound 2o with the best SI was used as a model compound for the stability test and was found to be stable at neutral pH, but under acidic conditions it slowly hydrolysed.

  New series of [1,3,4]thiadiazoles and fused [1,3,4]thiadiazoles were synthesized. The newly synthesized compounds were screened for their antibacterial activity against Staphylococcus aureus, Bacillus cereus, and Escherichia coli. Compounds 3b and 10a displayed the highest activity against E. coli with MIC value of 78.125 μg/mL. In addition, compound 10a exhibited the highest activity against B. cereus
