A synthesis of a rationally designed inhibitor of cytochrome P450 8B1, a therapeutic target to treat obesity.

ABSTRACT: Mice that lack the gene for expression of cytochrome P450 8B1 (P450 8B1) resist weight gain and improve glucose tolerance when fed a high-fat diet. Thus, the inhibition of P450 8B1 is a target to treat obesity-associated metabolic disorders. P450 8B1 is the enzyme that hydroxylates its substrate, 7α-hydroxy-cholest-4-en-3-one to 7α-,12α-dihydroxycholest-4-en-3-one, which ultimately results in the formation of cholic acid. Cholic acid is the 12α-hydroxylated bile acid implicated in enhanced absorption of cholesterol. The synthesis of a rationally designed inhibitor for P450 8B1 was achieved through the incorporation of a C12-pyridine in the C-ring of a steroid molecule. Seven days of new inhibitor treatment showed attenuation of glucose intolerance in mice that were fed a high fat and a hig
