[Stable analogues of coenzyme-substrate complex of spermidine/spermine-N1-acetyltransferase reaction. synthesis, interaction with the enzyme].

Convenient two-step synthesis of conjugates of HS-CoA and D-pantetheine with aminooxy analogues of Spm, Spd and Put was suggested. The use of acetone linker provided target conjugates with quantitative yields. The activity of CoA-derived "bisubstrate" inhibitors being active at microM concentrations was at least 100 times better than that of corresponding derivatives of D-pantetheine.
