Stereospecific irreversible inhibition of mammalian (S)-ornithine decarboxylase by (R)-(–)-hex-5-yne-1,4-diamine
Abstract
The synthesis of enantiomers of hex-5-yne-1,4-diamine, a potent irreversible inhibitor of (S)-ornithine decarboxylase (ODC, E,C. 4.1.1.17), is described; the stereospecificity of the inhibition by the (R)-isomer is consistent with a mechanism based on the microscope reversibility principle of enzyme catalysis.
