gdc 9545

Giredestrant (GDC-9545) potently competes with estradiol for binding and induces a conformational change within the ER ligand binding domain. Giredestrant has anti-tumor activity. Giredestrant, a non-steroidal ER ligand, is an orally active and selective estrogen receptor (ER) antagonist.

Giredestrant tartrate (Estrogen receptor antagonist 1) is a novel, orally active, selective and effective non-steroidal estrogen receptor antagonist. Giredestrant tartrate strongly binds to ER, resulting in the failure of ER to activate the transcription of targeted genes and promoting the degradation of ER protein. Giredestrant tartrate can be used to treat tumor diseases.
