Quadrosilan (INN, BAN) (brand name Cisobitan; former developmental code name KABI-1774) is a synthetic nonsteroidal estrogen that was developed in the 1970s and that is or has been used as an antigonadotropic agent in the treatment of prostate cancer.[1][2][3][4] It is an organosilicon compound, and is also known as 2,6-cisdiphenylhexamethylcyclotetrasiloxane.[3][5] Quadrosilan has estrogenic activity equivalent to that of estradiol,[6] and can produce feminization and gynecomastia as side effects in male patients.[7][8]
