Product Description

 

Fulvestrant CAS No.129453-61-8 Anti-Cancer Drug Substance

Fulvestrant is a steroidal anti that is used in the treatment of hormone-receptor positive metastatic breast cancer.

 

Fulvestrant, sold under the brand name Faslodex among others, is a medication used to treat hormone receptor (HR)-positive metastatic breast cancer in postmenopausal women with disease progression as well as HR-positive, HER2-negative advanced breast cancer in combination with palbociclib in women with disease progression after endocrine therapy. It is given by injection into a muscle.

Fulvestrant is a selective receptor degrader (SERD) and was first-in-class to be approved. It works by binding to the receptor and destabilizing it, causing the cell's normal protein degradation processes to destroy it.
