摘要:
Prostan-1-ol esters and intermediates for their preparation are described; the former compounds exhibit improved organ specificity and a longer duration of activity at lower dosages than the corresponding non-esterified prostaglandins and are useful, inter alia, in triggering abortion, inducing labor and regulating the menstrual cycle.
摘要:
