Abstract

The (R)- and (S)-isomers of the male antifertility agent alpha-chlorohydrin have been synthesized. When administered to rats, the (R)-isomer induced a period of diuresis and glucosuria, whereas the (S)-isomer, which possesses the antifertility activity, had no detrimental action on the kidney. Neither of the isomers of alpha-chlorohydrin nor those of an active analogue, 3-amino-1-chloropropan-2-ol, had any inhibitory activity on the oxidative metabolism of glucose or lactate in isolated kidney tubules. However, beta-chlorolactate, a metabolite common to both compounds, inhibited the oxidation of glucose, lactate, pyruvate and glutamate to CO2. It is proposed that the antifertility action of the (S)-isomers of alpha-chlorohydrin and 3-amino-1-chloropropan-2-ol is unrelated to the renal toxicity of the (R)-isomers, a toxic action involving the inhibition of oxidative metabolism by (S)-beta-chlorolactate or a further product of this metabolite.
