3- and 4-Pyridylalkyl Adamantanecarboxylates: Inhibitors of Human Cytochrome P45017α(17α-Hydroxylase/C17,20-Lyase). Potential Nonsteroidal Agents for the Treatment of Prostatic Cancer
摘要:
Various 3- and 4-pyridylalkyl 1-adamantanecarboxylates have been synthesized and tested for inhibitory activity toward the 17 alpha-hydroxylase and C-17,C-20-lyase activities of human testicular cytochrome P450(17 alpha). The 4-pyridylalkyl esters were much more inhibitory than their 3-pyridylalkyl counterparts. The most potent was (S)-1-(4-pyridyl)ethyl 1-adamantanecarboxylate (3b; IC50 for lyase, 1.8 nM), whereas the (R)-enantiomer 3a was much less inhibitory (IC50 74 nM). Nearly as potent as 3b was the dimethylated counterpart, the 2-(4-pyridylpropan-2-yl) ester 5 (IC50 2.7 nM), which was also more resistant to degradation by esterases. In contrast to their 4-pyridyl analogs, the enantiomers of the 1-(3-pyridyl)ethyl ester were similarly inhibitory (IC50 for lyase; (R)-isomer 8a 150 nM, (S)-isomer 8b 230 nM). Amides corresponding to the 4-pyridylmethyl ester 1 and the (S)-1-(4-pyridyl)ethyl ester 3b, respectively 11 and 15b, were much less inhibitory than their ester counterparts. On the basis of a combination of inhibitory potency and resistance to esterases, the ester 5 was the best candidate for further development as a potential nonsteroidal inhibitor of cytochrome P450(17 alpha), for the treatment of prostate cancer.

stereoselective amination of (hetero)aromatic ketones using transaminases have been studied, such as temperature, pH, substrate concentration, cosolvent, and source and percentage of amino donor, to further optimize the production of enantiopure amines using both (S)- and (R)-selective biocatalysts from commercial suppliers. Interesting enantiopure amino buildingblocks have been obtained, overcoming some limitations
