Abstract

We report the preliminary results of the synthesis and biochemical evaluation of a number of 4-hydroxyphenyl ketones as inhibitors of the isozyme of the enzyme 17beta-hydroxysteroid dehydrogenase (17beta-HSD) responsible for the conversion of androstenedione (AD) to testosterone (T), more specifically type 3 (17beta-HSD3). The results of our study suggest that we have synthesised compounds which are, in general, potent inhibitors of 17beta-HSD3, in particular, we discovered that 1-(4-hydroxy-phenyl)-nonan-1-one (8) was the most potent (IC(50) = 2.86 +/- 0.03 microM). We have therefore provided good lead compounds in the synthesis of novel non-steroidal inhibitors of 17beta-HSD3.
