Шаблон:Short description Шаблон:Drugbox

Dimethyltrienolone (developmental code name RU-2420) is a synthetic, orally active, and extremely potent anabolic–androgenic steroid (AAS) and 17α-alkylated 19-nortestosterone (nandrolone) derivative which was never marketed for medical use.[1] It has among the highest known affinity of any AAS for the androgen (and progesterone) receptors,[2][3] and has been said to be perhaps the most potent AAS to have ever been developed.[1]

Pharmacology

Pharmacodynamics

Dimethyltrienolone is an extremely potent agonist of the androgen and progesterone receptors and hence AAS and progestogen.[1] In animal bioassays, it was shown to possess more than 100 times the anabolic and androgenic potency of the reference AAS methyltestosterone.[1] The drug is not a substrate for 5α-reductase and so is not potentiated or inactivated in so-called "androgenic" tissues like the prostate gland or skin.[1] It is also not a substrate for aromatase and so has no estrogenic activity.[1] Due to its lack of estrogenicity, dimethyltrienolone has no propensity for causing estrogenic side effects like gynecomastia.[1] Because of its C17α methyl group and very high resistance to hepatic metabolism, dimethyltrienolone is said to be exceedingly hepatotoxic.[1]

Dimethyltrienolone, also known as 7α,17α-dimethyl-δ9,11-19-nortestosterone or as 7α,17α-dimethylestra-4,9,11-trien-17β-ol-3-one, as well as 7α,17α-dimethyltrenbolone, is a synthetic estrane steroid and a 17α-alkylated derivative of nandrolone (19-nortestosterone).[1] It is the 7α,17α-dimethyl derivative of trenbolone and the 7α-methyl derivative of metribolone,[6] as well as the δ9,11 analogue of metribolone and the δ9,11, 17α-methylated derivative of trestolone.[1]

History

Dimethyltrienolone was first described in 1967.[1][7] It was never marketed for medical use.[1]
