摘要:
17 alpha-Hydroxy-17 beta-methyl-5 beta-androstan-3-one,17 beta-methyl-5 alpha-androstane-3 alpha,17 alpha-diol,17 beta-methyl-5 alpha-androstane-3 beta,17 alpha-diol,17 alpha-methyl-5 beta-androstane-3 beta,17 beta-diol,17 beta-methyl-5 beta-androstane-3 alpha,17 alpha-diol and 17 beta-methyl-5 beta-androstane-3 beta,17 alpha-diol were synthesized for the first time. 1H NMR spectra of all four 17 xi-hydroxy/17 xi-methyl C-3 ketones and all eight C-3 alcohols were recorded in chloroform-d and pyridine-d5. Pyridine-induced chemical shifts are discussed. Thin-layer chromatographic data are given.

A simple and convenient method has been developed to prepare sulfates of anabolic 17-beta-hydroxy-17-alpha-methyl steroids. The sulfates of methandienone, 17-alpha-methyltestosterone, mestanolone, oxandrolone, and stanozolol were prepared. Different A-ring functions were not affected under the sulfation condition. The buffered hydrolyses of these sulfates provided the 17-epimers of the original steroids and 17, 17-dimethyl-18-nor-13(14)-ene steroids, presumably via the 17-carbocations.

the previously reported detection of long-term metabolites with a 17ξ-hydroxymethyl-17ξ-methyl-18-nor-5ξ-androst-13-en-3ξ-ol structure in the chlorinated metandienone analog dehydrochloromethyltestosterone (“oral turinabol”), in this study we investigated the formation of similar metabolites of metandienone and 17α-methyltestosterone with a rearranged D-ring and a fully reduced A-ring.

美二烯酮和甲基睾酮是口服活性合成代谢雄激素类固醇,具有 17α-甲基结构,在体育运动中被禁止,但在反兴奋剂分析中经常被检测到。继之前报道在氯化间二烯酮类似物脱氢氯甲基睾酮(“口服特力补”)中检测到具有 17ψ-羟甲基-17ψ-甲基-18-nor-5ψ-androst-13-en-3ψ-ol 结构的长期代谢物后,在这项研究中,我们研究了具有重新排列的 D 环和完全还原的 A 环的间二烯酮和 17α-甲基睾酮的类似代谢物的形成。使用半靶向方法,包括合成参考化合物、两种非对映异构体物质,即。 17α-羟甲基-17β-甲基-18-nor-5β-androst-13-en-3α-ol 及其 5α-类似物在施用甲基睾酮后被鉴定。在美二酮给药后的尿液中,仅检测到 5β-代谢物。此外,除了筛选程序中包含的经典代谢物外,在两次给药的尿液中还鉴定出了 3α,5β-四氢表甲基睾酮。除了适用于反兴奋剂分析之外,这些结果还为
