Colorectal cancer is the third common malignancy in man, with a significant morbidity and mortality rate. Three Schiff bases were synthesized by aminocondensation of 4-methyl-2-amino pyridine and three aromatic aldehydes and characterized by CHN analysis and advanced spectral techniques. They were screened for their cytotoxic properties using Sulphorhodamine-B (SRB) assay, and their antimigratory properties using wound healing assay against HCT116 (human colon cancer) cell lines. (E)-1-(2,3-dimethoxyphenyl)-N-(4-methylpyridin-2-yl)methanimine (DMPM) exhibited very low IC50 in SRB assay with good antimigratory activity as witnessed by wound healing assay. The protein processing enzyme MetAP2 has been identified as a molecular target for endothelial cell proliferation and angiogenesis and hence plays a key role in cancer therapy. The docking studies of DMPM with the active site of MetAP2 suggest it to be a potent chemotherapeutic agent in the treatment of colorectal cancer.
