Application

7-Chloro-4-hydrazinoquinoline was used in the preparation of new Schiff base hydrazone ligand via reaction with o-hydroxybenzaldehyde. It was also used in the preparation of N′-(E)-heteroaromatic-isonicotinohydrazide derivatives and the heteroaromatic 7-chloro-4-quinolinylhydrazone derivatives.

A new hydrazone ligand, HL, was prepared by the reaction of 7-chloro-4-hydrazinoquinoline with o-hydroxybenzaldehyde. The ligand behaves as monoprotic bidentate. This was accounted for as the ligand contains a phenolic group and its hydrogen atom is reluctant to be replaced

Two series of N'-(E)-heteroaromatic-isonicotinohydrazide derivatives (3a-f and 4a-b) and 1-(7-chloroquinolin-4-yl)-2-[(heteroaromatic)methylene]hydrazone derivatives (5a-f and 6a-b) have been synthesized and evaluated for their in vitro antibacterial activity against Mycobacterium tuberculosis H37Rv. Several compounds were noncytotoxic and exhibited significant minimum inhibitory concentration (MIC)
