the synthesis and evaluation of a series of cholesterol side-chain analogs as mechanistic probes of three important Mycobacterium tuberculosis cytochromeP450 enzymes that selectively oxidize the ω-position of the methyl-branched cholesterol side-chain. To probe the structural requirements for the thermodynamically disfavored ω-regiospecificity we compared the binding of these substrateanalogs to each
