A series of unsaturatedsteroids bearing a 3-carboxy substituent has been prepared and assayed in vitro as inhibitors of human and rat prostatic steroid 5 alpha-reductase (EC 1.3.1.30). It is proposed that the observed tight binding of the 3-androstene-3-carboxylic acids is due to mimicry of a putative, high-energy, enzyme-bound enolate intermediate formed during the NADPH-dependent conjugate reduction
