which guided the synthesis of a focused array of compounds. Subsequently, seven compounds were selected (1-7) on the basis of their optical and chemical (stability) properties and were submitted to a screen against a panel of dehydrogenase enzymes. Probe 5 was found to be highly selective for bacterial, rat, and human 3alpha-HSD enzymes. The kinetic parameters were obtained for human 3alpha-HSD enzyme
