Background: Amidrazones have been reported to have significant anti-tumor properties
against several cancer cell lines.
Objectives: The current project aims to profile the structure-anticancer activity relationship of
Methods: Fifteen phenyl-amidrazone-piperazine derivatives were prepared and tested against four
cancer cell lines (leukemia, prostate, breast and colon cancers).
Results: Six compounds illustrated low micromolar anticancer IC50 values, while the remaining
compounds were either inactive or of moderate potencies. All compounds were virtually nontoxic
against normal fibroblast cells.
Conclusion: Docking into the oncogenic kinase bcr/abl illustrated the critical importance of (i) phalogen
substituent on the ligand's phenyl ring and (ii) the presence of positive ionizable moiety at
the ligand's piperazine fragment for anticancer activity.
