3β,11α-Dihydroxy-5α-chloro-6,19-oxidoandrostan-17-one and method of preparation of 3β,11α-dihydroxy-5α-chloro-6,19-oxidoandrostan-17-one

摘要

Is this about a relationship called 3ss,11? dihydroxy-5? -chloro-6,19-oxidoandrostan-17-one with model 2 and its mode of production. This is because the enzyme system contained in the cells of Isaria farinosa KW1.1 strain results in acetyl group hydrolysis at C-3 and regional selective hydroxylation at 11? substrates. The product thus obtained is extracted from the aquatic culture of the micro-organism by extraction by an organic solvent that does not mix with water (chloroform).
