crystallographic analysis. Each of these compounds is a powerful competitive inhibitor of human placental microsomal aromatase, and stereoselectivity of inhibition was observed (Ki values for 2 and 3 were 7 and 75 nanomolar, respectively). Spectroscopic studies with purified aromatase indicate that the inhibition process involves reversible binding of oxirane oxygen to the heme iron of the enzyme. The (19R)- and (19S)-10

The novel 10β-thiiranyl-4-estrene-3,17-diones (5) and (6) have been synthesized by the action of triphenylphosphine sulphide–picric acid on oxirane precursors and show potent inhibition of placental aromatase; the (19R)-isomer (5) is 75 times more effective than the (19S)-isomer (6).
