ICI-85966 (former tentative brand name Stilbostat ), also known as diethylstilbestrol (DES) bis(di(2-chloroethyl)carbamate) , is a synthetic , nonsteroidal estrogen and cytostatic antineoplastic agent of the stilbestrol group and a nitrogen mustard ester of diethylstilbestrol (DES) which was developed for the treatment of breast cancer and prostate cancer but was never marketed (possibly due to the toxicity of DES).[ 1] [ 2] [ 3] [ 4] [ 5]
