Chemistry:Palazestrant

Palazestrant is an investigational new drug which is being evaluated for the treatment of estrogen receptor-positive (ER+) breast cancer, with a dual mechanism of action as both a complete estrogen receptor antagonist (CERAN) and a selective estrogen receptor degrader (SERD). This orally bioavailable small molecule has demonstrated potent activity against both wild-type and mutant forms of the estrogen receptor.
