LG-120907 is a nonsteroidal antiandrogen (NSAA) of the quinoline group which was developed by Ligand Pharmaceuticals along with selective androgen receptor modulators (SARMs) like LG-121071 and was never marketed.[1][2] [3][4] The drug is a high-affinity antagonist of the androgen receptor (AR) with a Ki value of 26 nM and has been found to inhibit growth of the ventral prostate and seminal vesicles in male rats without increasing circulating levels of luteinizing hormone or testosterone.[1][2][3] However, this tissue selectivity has not been assessed in humans.[5] LG-120907 is orally active and shows greater oral potency than the arylpropionamide NSAA flutamide.[1][3][4]
The 7-fluoro derivative of LG-120907, LG-105, is also a potent NSAA, and appears to possess greater potency in comparison.[3] Conversely, the 6-ethyl, 8-didesmethyl analogue of LG-120907, LG-121071, is a SARM with potent androgenic activity equivalent to that of dihydrotestosterone (DHT).[1][3]
