By stereospecific microbial reduction with Rhodosporidium rubrum or Rhodotorula glutinis, 17 alpha-cyano-methyl-4-estren-17 beta-ol-3-one was metabolized to 17 alpha-cyanomethyl-5 alpha-estrane-3 beta,17 beta-diol (50%) and 17 alpha-cyanomethyl-5 alpha-estrane-3 alpha,17 beta-diol (30%). By Clostridium paraputrificum the same substrate was reduced… CONTINUE READING
