In this study, the antileukemic effects of three isomeric pregnadienedione steroids [i.e., cis-guggulsterone, trans-guggulsterone, and 16-dehydroprogesterone] were investigated in HL60 and U937 cells as well as in primary leukemic blasts in culture. Our results show that all three compounds inhibited

Eubacterium sp. 144 biotransformed 16-dehydroprogesterone by initially hydrating approx 50% to 16 alpha-hydroxyprogesterone. The detection of this reaction was dependent, in part, on the solubility state of 16-dehydroprogesterone and was less extensive when the concentration of methanol was insufficient to

Suspensions of Eubacterium sp. strain 144, prepared from cells grown with 16-dehydroprogesterone, catalyzed the reduction of this steroid to 17-isoprogesterone at a very low rate. Modifications of the assay to optimize the pH (5.5) and increase the steroid solubility (10%
