Product Description
CAS No.129453-61-8 Anti-Cancer Drug Substance
Pharmacodynamics
Fulvestrant is an antiestrogen which acts as an antagonist of the estrogen receptor (ER) and additionally as a selective estrogen receptor degrader (SERD). It works by binding to the estrogen receptor and making it more hydrophobic, which makes the receptor unstable and misfold, which in turn leads normal processes inside the cell to degrade it.
In addition to its antiestrogenic activity, fulvestrant is an agonist of the G protein-coupled estrogen receptor (GPER), albeit with relatively low affinity (10–100 nM, relative to 3–6 nM for estradiol).
Fulvestrant is a steroidal antiestrogen that is used in the treatment of hormone-receptor positive metastatic breast cancer.
Xi'an Libang Pharmaceutical Co..Ltd developed Fulvestrant API since 2007 and filed the DMF in US FDA in 2009.
