Abstract:
A series of new N-pyrazolylbenzamides (5a-x) were synthesized by aroylation of 5-amino-1-phenyl-3-tbutylpyrazole. The structures of synthesized compounds were established based on spectral (FTIR, (1)H NMR, ESI Mass) analysis and purity was ascertained by HPLC. The antibacterial screening revealed that seven molecules exhibited an excellent antibacterial activity and eight compounds demonstrated considerable antifungal activity. Three molecules of the series 5e, 5s and 5w were found to be highly effective against Klebsilla pneumoneia with MIC of 3.12 µg/ml. Compounds 5b, 5f, 5g and 5o exhibited significant antitubercular activity with MIC of 12.5 µg/ml.
