Abstract:
Based on the anti-mycobacterial activity of various acid hydrazides, a series of substituted 3-hydrazinyl-3-oxo-propanamides has been designed. The target compounds have been synthesized from diethylmalonate using substituted amines and hydrazine hydrate in ethanol. Computational studies and anti-tubercular activity screenings were undertaken to test their inhibitory effect on protein kinase PknB from Mycobacterium tuberculosis. Binding poses of the compounds were energetically favorable and showed good interactions with active site residues. Designed molecules obey the Lipinski’s rule of 5 and gave moderate to good drug likeness score. Among the sixteen compounds (1-16) taken for in silico and in-vitro studies, 3 compounds (11, 12 and 15) have shown good binding energies along with exhibiting good anti-tubercular activity and thus may be considered as a good inhibitors of PknB
