3β,5α,6β-Trihydroxyandrostan-17-one
The title compound, C(19)H(30)O(4), is an androstan-17-one derivative synthesized from the dehydro-epiandrosterone through a sequential addition of an oxidant, followed by a trans-diaxial opening of the epoxide generated, with Bi(OTf)(3) (OTf is trifluoro-methane-sulfonate). The six-membered rings have a slightly flattened chair conformation, while the five-membered ring adopts a 14-α envelope ...
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 کاملA17 17..17
Early intervention by teams specialising in the treatment of early psychosis has been suggested to enhance outcome in the early phase of psychotic illness. Two papers in the Journal address this topic. The first examines the cost-effectiveness of these services, while the second examines the 5-year outcome of one such service. McCrone and colleagues (pp. 377–382) report that although their spec...
