Abstact

Chk1 inhibitors have emerged as a novel class of neoplastic agents for abrogating the G2 DNA damage checkpoint arrest. Analogs of the Chk1 inhibitor, 3-ethylidene-1,3-dihydro-indol-2-one, were synthesized and tested in vitro for their inhibitory activities. The most promising compound identified from this series is analog 28, which possesses potent enzymatic and cellular activities.
