MedKoo CAT#: 333075

CAS#: 2407529-33-1 (tartrate)

Description: Giredestrant, also known as GDC-9545 and RG6171, is a SERD. GDC-9545 is an orally available selective estrogen receptor degrader/downregulator (SERD), with potential antineoplastic activity. Upon oral administration, SERD GDC-9545 specifically targets and binds to the estrogen receptor (ER) and induces a conformational change that promotes ER degradation.
