All of them displayed enzyme-inhibiting activity, and 3-cyclohexyl derivative 2g and 3-cyclohexylmethyl derivative 1h both proved more potent (greater than 140-fold) than the clinically effective agent aminoglutethimide [3-(4-aminophenyl)-3-ethylpiperidine-2,6-dione, AG]. As with AG and its derivatives, the 1R-(+)-enantiomer of 1h was responsible for the enzyme inhibitory activity. These
