Abstract
A novel series of diaryl ureas containing different linker groups were designed and synthesized. Their in vitro antitumor activity against MX-1, A375, HepG2, Ketr3 and HT-29 was evaluated using the standard MTT assay. Compounds having a rigid linker group such as vinyl, ethynyl and phenyl showed significant inhibitory activity against a variety of cancer cell lines. Specifically, compound 23 with a phenyl linker group demonstrated broad-spectrum antitumor activity with IC50 values of 5.17-6.46 μM against five tested tumor cell lines. Compound 23 is more potent than reference drug sorafenib (8.27-15.2 μM), representing a promising lead for further optimization.
