Higher homologs of lysine derivatives consisting of l-lysine and dicarboxylic acids were synthesized. The acids ranged from carbon atoms C11 to C17 and C20 and were coupled with ∊-benzyloxycarbonyl-lysine ethyl ester (Lys (Z)-OEt) by conventional methods of peptide synthesis. The removal of the Z-group from the protected compounds by hydrogenation gave the final products as bifunctional agents: undecanedioyl-Lys-OEt, dodecanedioyl-Lys-OEt, tridecanedioyl-Lys-OEt, tetradecanedioyl-Lys-OEt, pentadecanedioyl-Lys-OEt, hexadecanedioyl-Lys-OEt, heptadecanedioyl-Lys-OEt and eicosanedioyl-Lys-OEt. All the products showed a greater inactivating effect on several phages than azelaoyl-Lys-OEt, which showed the highest phage-inactivating effect among the compounds reported in our previous paper.
