ABSTRACT

A new series of Hydrazone derivatives(IIIa-IIIm) were obtained by synthesizing 2-(benzamido) benzohydrazide with different aromatic and heterocyclic aldehydes. These derivatives are characterized by FTIR, 1H-NMR, 13C-NMR and Mass spectra. The synthesized derivatives were screened for their in vitro antibacterial activity against Klebsella Pneumoniae, Salmonella Paratyphi, Escherischia Coli, Basillus Substilis where IIIc, IIIe compounds showed significant activity against Klebsella Pneumoniae. IIIa-IIIj compounds were screened for their in vitroantifungal activity against fungal spores like Aspergillus Nigrum, Aspergillus Clavatus, Penicillium Notatum and Colleotrichem Coffeanum where IIIa, IIIe compounds showed significant activity against Aspergillus Nigrum. IIIa, IIIl, IIIm compounds were screened for analgesic activity among these IIIm compound showed significant activity. In vitrocytotoxic activity of IIIb compoundshowed significant cytotoxic activity against all the five cell lines tested in the region of 9, 23, 33, 26, 17μm for CEM, L1210, Molt 4/C8, HL60 & BEL 7402 respectively.

Keywords: Klebsella Pneumoniae, Salmonella Paratyphi, Escherischia Coli.
