  Reaction of androst-5-en-17-one with hypobromous acid and its use for synthesis of 19-oxygenated 5-ene and 4-en-6-one steroids

  摘要：

  Reaction of androst-5-en-17-one (1) with hypobromous acid using a short reaction rime (30 min) along with a careful isolation procedure gave, for the first time, the addition 5 alpha-bromo-6 beta-hydroxyandrostan-17-one (3), in 43% yield. This bromohydrin was much more reactive than 5 alpha-brormo-3 beta-acetoxy-6 beta-hydroxyandrostan-17-one (4) towards KHCO3 and HClO4. The high reactivity of compound 3 was found ro be a principal reason for the difficulty in isolating this compound the addition reaction so far. 19-Hydroxyandrost-5-en-17-one (16) and androst-5-ene-17,19-dione (18), ns well ns 19-hydroxyandrost-4-ene-6,17-dione (28) and androst-4-ene-6,17,19-trione (29), were synthesised through hypoiodite reaction of the bromohydrin 3 as a key reaction.

• Synthesis of Androst-5-en-7-ones and Androsta-3,5-dien-7-ones and Their Related 7-Deoxy Analogs as Conformational and Catalytic Probes for the Active Site of Aromatase

  A series of androst-5-en-7-ones and androsta-3,5-dien-7-ones and their 7-deoxy derivatives, respectively, were synthesized and tested for their abilities to inhibit aromatase in human placental microsomes. All the steroids inhibited the enzyme in a competitive manner with K-i's ranging from 0.058 to 45 mu M. The inhibitory activities of 17-oxo compounds were much more potent than those of the corresponding 17 beta-alcohols in each series. Steroids having an oxygen function (hydroxy or carbonyl) at C-19 were less potent inhibitors than the corresponding parent compounds having a 19-methyl group. 3,5-Dien-7-one 24 and its 19-hydroxy and 19-oxo derivatives (12 and 13) as well as 19-oxo-5-en-7-one 3 caused a time-dependent inactivation of aromatase only in the presence of NADPH in which the k(inact) values of 19-als 3 and 13 (0.143 and 0.189 min(-1), respectively) were larger than those of the corresponding 19-methyl (23 and 24) and 19-hydroxy (1 and 12) steroids, respectively. 19-Nor-5-en-7-one 4 but not its 3,5-diene derivative 14 also inactivated the enzyme in a time-dependent manner. In contrast, 7-deoxy steroids 21 and 27, having a 19-methyl group, did not cause it. The inactivations were prevented by the substrate androstenedione, and no significant effects of L-cysteine on the inactivations were observed in each case. The results suggest that oxygenation at C-19 would be at least in part involved in the inactivations caused by the inhibitors 23 and 24. The conjugated enone structures should play a critical role in the inactivation sequences.
