Microtubule is one of the important targets for cancer treatment. A novel class of diaryl substituted imidazo[4,5-c]pyridin-2-ones and imidazo[4,5-c]pyridines were designed based on combination principles by merging the structures of β-lactams and purine-type compounds known as tubulin polymerization inhibitor and katanin activity up-regulator, respectively. Their antitumor activities were evaluated in vitro and the mechanism was elucidated, leading to the identification of 1,6-diaryl-1H-imidazo[4,5-c]pyridin-2(3H)-one 20b as the first bifunctional agent that can target both tubulin and katanin simultaneously. The in vivo assays verified that compound 20b significantly inhibited xenograft tumor growth with good pharmacokinetic characteristics, demonstrating a promising potential for further development into anti-tumor drug candidates with a unique mechanism of dual-targeting microtubule.
