After incubation with 3mm-alpha-chlorohydrin, glyceraldehyde 3-phosphate dehydrogenase and triose phosphate isomerase activities were decreased by approx. 90% and 80% respectively, and in some experiments aldolase was also inhibited.

The dose-dependent inhibition in vitro of the glycolytic enzymes glyceraldehyde-3-phosphate dehydrogenase (GAPDH) and triosephosphate isomerase (TPI) of distal cauda epididymal rat spermatozoa by (R)-, (S)- and (R,S)-ornidazole (ORN), (R,S)-alpha-chlorohydrin (ACH) and 1-chloro-3-hydroxypropanone (CHOP) was compared.

The high phosphatase activity hydrolyses the ester to alpha-chlorohydrin which undergoes oxidation to (S)-3-chlorolactaldehyde, a specific inhibitor of sperm glyceraldehyde-3-phosphate dehydrogenase and triosephosphate isomerase, thereby exhibiting an anti-glycolytic action.

A difference in metabolic rate or route of the isomers may account for their differing physiological activities. 4. (+)- and (-)-aminochloropropanol exhibited identical in vitro inhibitory activities on the glycolytic enzymes glyceraldehyde-3-phosphate dehydrogenase and triosephosphate isomerase, and were substrates for monoamine oxidase to equivalent extents.
