RU-58841 化学特性,用途語,生産方法

• 説明

  RU-58841 is a non-steroidal antiandrogen that binds to the androgen receptor (Kd = 1.8, 1.1, 5.6, 1.3, and 1.4 nM for human, rat, mouse, hamster prostate, and hamster flank organ receptors, respectively). In vivo, topical administration of RU-58841 (1-100 μg per animal) reduces size of the flank organ without affecting sex organs in a dose-dependent manner in hamsters. It has no effect on sex organ weight in intact rats when administered percutaneously, subcutaneously, or orally at doses up to 1 mg per animal. RU-58841 (5% v/v) also induces hair regrowth in the bald frontal scalps of postpubertal stumptailed macaques, a model for male pattern baldness.

• 使用

  RU 58841, is a specific androgen receptor antagonist or anti-androgen, that has shown to have effect on hair growth.

• 製造方法

  RU58841 is active against baldness and is commercially available. The previously reported synthesis uses phosgene, three discrete inert atmosphere steps and three steps that require flash chromatography. Our synthesis uses no phosgene, only one inert atmosphere step and does not require flash chromatography.
  Alternative synthesis of the anti-baldness compound RU58841

• Synthesis Reference(s)

  A bromine–nitro substitution at tertiary carbon and using 2-nitropropane as leaving group enable a short phosgene-free synthesis of RU58841.

• 生物活性

  Androgens are mainly produced in the adrenal glands and testes. They are male hormones responsible for sex-related development. The well-known androgen is testosterone. Dihydrotestosterone (DHT) is also an androgen, which is a byproduct of testosterone. Although DHT is important for male development and physical health, it can cause hair loss. RU58841 is a topical anti-androgen drug that counteracts the effects of dihydrotestosterone (DHT) by binding to the androgen receptors of the hair follicles, preventing DHT from interacting with the androgen receptors of the hair follicles. Therefore, the hair shrinkage process does not begin, ensuring that the hair undergoes a normal growth cycle.
