A total of 29 novel compounds bearing N1-(2-aryl-1, 3-thiazolidin-4-one)-N3-aryl ureas were designed, synthesized and evaluated for their biological activities. The structure-activity relationships (SARs) and binding modes of this series of compounds were clarified together. Compound 29b was identified possessing high potency against multi-tyrosine kinases including Ron, c-Met, c-Kit, KDR, Src and IGF-1R, etc. In vitro antiproliferation and cytotoxicity of compound 29b against A549 cancer cell line were confirmed by IncuCyte live-cell imaging.
