Abstract
Three 22-(p-chloroaryl) analogues of cholesterol (6a-c) were synthesized and evaluated as potential inhibitors of the adrenal cholesterol side-chain cleavage enzyme, in comparison with the known 20-aryl analogue, 20-(p-chlorophenyl)-5-prenen-3 beta,20-diol (2b). All were potent inhibitors. An oxygen at C-22 (analogues 6a and 6b) enhanced the strong binding to the enzyme. Two compounds (6b and 6c) are potential substrates of the enzyme. Possible pharmaceutical uses for these compounds and their derivatives are discussed.
