  • Publication number: 20090318376
    Abstract: The present invention relates to a high throughput screening method of a binding inhibitor between caspase3 and xIAP and chromomycin screened using the same, and more specifically, the present invention provides a method for screening anticancer substance, the method comprising the steps of reacting caspase3 or xIAP and candidate inhibitors of the binding between caspase3 and xIAP on a biochip for detecting caspase3:xIAP interaction, and selecting a candidate substance inhibiting the binding of caspase3 to xIAP as an anticancer substance, and an anticancer agent inhibiting caspase3:xIAP binding, which is screened by the above method. According to present invention, it is possible to develop a target-oriented anticancer agent focused on xIAP and caspase3, apoptosis-related proteins and thus it can be applied to tailored medication and combination therapy.
