The present invention provides salts of (E)-N-methyl-4-((2-(4-((E)-4,4,4-trifluoro-1-(3-fluoro-1H-indazol-5-yl)-2-phenylbut-1-en-1-yl)phenoxy)ethyl)amino)but-2-enamide represented by the formula I and acids, and crystals thereof, possessing a potential to be used as drug substance in pharmaceuticals. [Chem. 1]
novel 6-OH-benzothiophene (BT) derivatives targeting ERα and deriving from Raloxifene were designed, synthesized, and biologically evaluated as covalent antagonists. Driven by the antiproliferative efficacy in ER+ breast cancer cells, our chemical optimization finally led to compound 19d that with potent antagonisticactivity in ER+ tumor cells while without agonistic activity in endometrial cells. Moreover
X-ray crystallography study and optimization of novel benzothiophene analogs as potent selective estrogen receptor covalent antagonists (SERCAs) with improved potency and safety profiles
Disclosed herein are compounds, or pharmaceutically acceptable salts thereof, and methods of using the compounds for treating breast cancer by administration to a subject in need thereof a therapeutically effective amount of the compounds or pharmaceutically acceptable salts thereof. The breast cancer may be an ER-positive breast cancer and/or the subject in need of treatment may express a mutant ER-α protein.
