Abstract

A series of several diazenyl Schiff base derivatives were designed and synthesized through azo coupling of diazotised primary amines with the novel synthesized Schiff base ligand (E)-N-((2-chloroquinolin-3-yl) methylene)-4-phenylthiazol-2-amine. All the synthesized compounds have been analysed by different spectral techniques such as elemental analysis, 1H NMR, FT-IR, UV-Vis and LC-MS for their structural confirmation. The above conjugates have been studied for their solvent effects by treating them with different solvents. The results of in vitro cytotoxic study of the synthesized compounds against MCF 7 (human breast cancer cell line) and K562 (Chronic Myeloid Leukemia cell line) revealed that some of the compounds show cytotoxic effect. However, the compounds (NZ)-N-(((4-bromo-3-methylphenyl) diazenyl) (2-chloroquinolin-3-yl) methylene)-4-phenylthiazol-2-amine: (5d) and 4-(((Z)-(2-chloroquinolin-3- yl)(4-phenylthiazol-2-ylimino)methyl)diazenyl)phenol (5e) showed potent cytotoxic activity in comparison to other compounds against MCF 7. Corroborating the results of anticancer activity, it is found to be observed that the compound 4- (((Z)- (2-chloroquinolin-3-yl) (4-phenylthiazol-2-ylimino)methyl) diazenyl) phenol (5e) showed excellent anticancer activity against MCF 7, which is further justified by the apoptosis study through Annexin V-FITC/PI analysis.
