Abstract:
Three functional groups (2-propenyl, 2-propynyl, and 2,3-butadienyl) were introduced onto one of the terminal amino groups of spermidine. Of the six compounds synthesized, N-(3-aminopropyl)-N'-2,3-butadienyl-1,4-butanediamine (N(8)-butadienyl Spd) and N-[3-(2,3-butadienylamino)propyl]-1,4-butanediamine (N(1)-butadienyl Spd) irreversibly inactivated human spermine oxidase (SMO) and N(1)-acetylpolyamine oxidase (APAO). Interestingly, N(8)-butadienyl Spd inactivated SMO far more potently than N,N'-di-2,3-butadienyl-1,4-butanediamine (MDL 72527).

Reversible inhibitors like edrophonium bind to a specific part of the enzyme called the anionic catalytic site. They form noncovalent bonds, which means they are not strongly attached to the enzyme. This creates a temporary and less stable enzyme–inhibitor complex,...
