  Synthesis and SAR study of novel pseudo-steroids as potent and selective progesterone receptor antagonists

  摘要：

  Synthesis of novel 7-pseudo-steroids 1c has been achieved from trenbolone 3 via an efficient 14 step sequence with overall yields of 10-15%. Various substitutions were incorporated at both the aromatic side chain as well as the D ring. The orientation of aromatic side chain at C10 plays a crucial role for progesterone receptor (PR) activity. Compound 2a (T47D = 1 nM) with -NMe2 para to the aromatic group along with spirofurane groups in the D ring was the optimal substitution. All compounds were also evaluated for glucocorticoid receptor (GR) antagonist activities in vivo in a rat and found efficacious in uterine complement C3 assay via the oral route of administrations.

• Degradation of Synthetic Androgens 17α- and 17β-Trenbolone and Trendione in Agricultural Soils
  作者：Bushra Khan、Linda S. Lee、Stephen A. Sassman

  DOI：10.1021/es702690p

  日期：2008.5

  17 beta-trenbolone acetate (TBA) is a synthetic androgenic steroid hormone administered as a subcutaneous implant for growth promotion in beef cattle. TBA is converted metabolically to primarily 17 alpha-trenbolone and trendione, and excreted in manure from implanted cattle. To predict the persistence of synthetic androgens once land-applied, aerobic degradation rates in two contrasting agricultural soil types (clay loam and a sandy soil) of both trenbolone isomers (17 alpha and 17 beta) and their primary metabolite trendione were measured and isomer interconversion was assessed. The impact of manure application was also evaluated in the clay loam soil. A pseudo first-order exponential decay model was derived assuming irreversible transformation and no impact of sorption on availability for degradation. The model generally resulted in good fits to the data. Both isomers degraded to trendione in a similar manner with half-lives (t(1/2)) on the order of a few hours to 0.5 days at applied concentrations of <= 1 mg/kg. Similar degradation rates were observed in the presence and absence of manure applied at rates typical for land-application of cattle manure. Trenbolone degradation was concentration-dependent with degradation rates decreasing with increasing applied concentrations. Trendione, whether applied directly or produced from trenbolone, persisted longer than trenbolone with t(1/2) values of I to 4 days. A small amount (1.5%) of conversion of trendione back to 17 beta-trenbolone was observed during aerobic incubation regardless of the applied concentration. A small amount of 17 alpha-isomer also converted back to 17 beta-trenbolone, presumably through trendione. In automated soils, no degradation of 17 alpha- or 17 beta-trenbolone was observed during the first 3 days, and trendione degradation was relatively small compared to a microbially active soil.
