  Probing the binding pocket of the active site of aromatase with 6-ether or 6-ester substituted androst-4-ene-3,17-diones and their diene and triene analogs

  摘要：

  A series of 6-ester- (3 and 4) and 6-ether- (7 and 8) substituted androst-4-ene-3,17-diones (androstenediones) and their 1,4-diene analogs (5 and 6, and 9 and 10) as well as CB-substituted 4,6-diene and 1,4,6-triene steroids 11 and 12 were synthesized as aromatase inhibitors to gain insight into the structure-activity relationship between various substituents and inhibitory activity. All of the inhibitors synthesized blocked aromatase in a competitive manner. The inhibitory activities of all of the steroids, except for the 6 beta -benzoates 4g and 6h and the 6 beta -acetate 6a, were fairly effective to very powerful (K-i: 7.0 -320 nM). The 6 alpha -n-hexanoyloxy- and 6 alpha -benzyloxyandrostenediones (3e and 7e) were the most potent inhibitors (K-i: 7.0 nM each). In the series of 4-ene and 1,4-diene steroids, the 6 alpha -substituted steroids had higher affinity for the enzyme than the corresponding 6 beta -isomers. In the 1,4-diene steroid series, 6 beta -substituted steroids 6a, e, g, and 10a, b, e caused a time-dependent inactivation of aromatase, whereas their 6 alpha -isomers 5 and 9 essentially did not. The ether-substituted 1,4,6-trienes 12 inactivated the enzyme in a time-dependent manner; in contrast, their 4,6-diene analogs 11 did not. The substrate androstenedione blocked the inactivation, but no significant effect of L-cysteine was observed. Based on molecular modeling with the PM3 method, along with the present inhibition and inactivation results, it is thought that both the steric effects of the 6-substituents as well as the electronic effects of the C-6 oxygen functions play a critical role in the binding of inhibitors to the active site of aromatase.

• Convenient method for the functionalization of the 4- and 6-positions of the androgen skeleton

  日期：——

  The preparation and reactivity of steroidal vinyldiazo compounds is reported, providing a convenient, substituent tolerant, chemo- and stereoselective entry into 4- and 6-substituted androgen analogues from a common precursor. Under dirhodium catalysis, O–H insertion occurs at the carbenoid site, leading to 4-substituted steroids, but under silver catalysis, O–H insertion occurs at the vinylogous position, leading to 6-substituted steroids.
