Quadrosilan (INN , BAN ) (trade name Cisobitan ; former developmental code name KABI-1774 ) is a synthetic , non-steroidal 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]
