THIQ 40
THIQ-40 is a tetrahydroisoquinoline-based, orally active, and selective estrogen receptor ERα degrader (SERD) (IC50=17 nM), with antitumor efficacy. THIQ-40 possesses functional ERα antagonistic activity, promotes ERα degradation and forms stable ERαLBD complexes. THIQ-40 shows the characteristic of rapid racemization in multi-species plasma. THIQ-40 can be widely applied to studies on the relevant mechanisms and drug development of ERα-positive breast cancer.
