    Abstract:
    A series of pyrrolo[2,3-b]pyridine derivatives bearing the 1,8-naphthyridin-2-one moiety were synthesized, and evaluated for their antiproliferative activity against four cancer cell lines (HT-29, A549, H460, and U87MG) and six tyrosine kinases (c-Met, Flt-3, PDGFR-β, VEGFR-2, EGFR, and c-Kit) inhibitory activities in vitro. Most compounds showed moderate to excellent potency, with the most promising analogue 32 showing Flt-3/c-Met IC50 value of 1.16/1.92 nM. Structure-activity relationship studies indicated that the hydrogen atom served as R1 group was benefited to the potency, and mono-electron-withdrawing groups (mono-EWGs) on the phenyl ring (such as R3 = 4-F) showed a higher preference for antiproliferative activity.
