ACP-105 is an orally available, selective amd potent androgen receptor modulator (SARM), with pEC50s of 9.0 and 9.3 for AR wild type and T877A mutant, respectively. The half-lives of ACP-105 (compound 1) in human hepatocytes is measured and found to be 5.0 h[1].

| In Vivo |
ACP-105 enhances freezing in both sham-irradiated and irradiated mice (effect of ACP-105: F=5.44; p=0.028). For MAP-2 immunoreactivity in the cortex of sham-irradiated mice, there is a brain area×ACP-105 interaction (F=6.655; p=0.0027). While ACP-105 reduces MAP-2 immunoreactivity in the sensorymotor cortex, there is a trend towards increased MAP-2 immunoreactivity in the enthorhinal cortex[2].

Mice[2] Two-month-old C56Bl/6J female mice are kept on a 12:12 hr light-dark schedule (lights on at 6 AM) with lab chow and water given ad libitum. Following i.p. anesthesia (ketamine, 80 mg/kg and xylazine, 20 mg/kg), mice are sham-irradiated (n=7 sham vehicle-treated mice and n=7 ACP-105-treated mice) or irradiated (n=8 vehicle-treated mice and n=7 ACP-105-treated mice) using a dose of 10 Gy in a Mark 1 Cesium Irradiator. Twenty-four hours following irradiation, the mice are implanted with Alzet minipumps filled with ACP-105 at 1 mg/kg/day or 1.09 mg/200 μL in 10% Tween in saline or vehicle. Behavioral testing starts two weeks after irradiation. Mice receives three trials per day for three subsequent days. Mice are tested for fear conditioning in week 2. During contextual fear conditioning, mice learn to associate the environmental context with a mild foot shock. Contextual conditioned fear is assessed during the first 3 minutes of the contextual test trial when freezing behavior is most robust. Cued conditioned fear is assessed during the presentation of the tone (the last 3 minutes of the trial)[2].
