17β-Hydroxy-17α-(hydroxymethyl)estr-4-en-3-one
The title compound, C(19)H(28)O(3), the fungal-transformed metabolite of the steroid methyl-oestrenol contains four fused rings A, B, C and D. Ring A adopts a half-chair and the trans-fused rings B and C adopt chair confirmations; the five-membered D ring is folded like an envelope. In the crystal, adjacent mol-ecules are linked by O-H⋯O(carbon-yl) and O-H⋯O(hy-droxy) hydrogen bonds into a laye...

In the title compound, C(22)H(28)N(2)O(2)·H(2)O, rings B and C adopt chair conformations. Ring A adopts an envelope conformation, with the non-fused C atom adjacent to the fused C atom bearing a methyl group as the flap atom. Ring D also adopts an envelope conformation, with the fused C atom not bearing a methyl group as the flap atom. The water mol-ecule links the mol-ecules via O-H⋯O and O-H⋯...
متن کامل17α-Hydroxy-4-pregenen-3-one (17 αP) assay, using acetylcholinesterase enzyme as tracer
17a-hydroxy-4-pregnen-3-one (17aP) hormone is a precursor of other steroid hormones and radioimmunoassay has already been used to measure it, but a simple and rapid "Enzyme Linked Immunosorbant Assay" (ELISA) is described and validated here. A general procedure for prepara-tion of the acetylcholinesterase labelled steroid is described, which is applicable to any steroid. Use of acetyl...

متن کامل17β-Hydroxy-17α-methylandrosta-1,4-dien-3-one
The title compound, C20H28O2, is a steroid with strong anabolic properties. The present solvent-free form crystallizes with two mol-ecules per asymmetric unit. In the crystal, both mol-ecules are involved in the formation of O-H⋯O hydrogen-bonded chains which extend along the b-axis direction.
