Bioactive primary and secondary amines, when acylated with the Z-Gly-Phe group, are transported into pinocytic cells, such as macrophages, P-815 mastocytoma, SV-40 3T3, and leukemia 1210, much faster than the parent compounds.Amines, such as lysosomotropic detergents and nitrogen mustard, which are deactivated by acylation, are unmasked by enzymic action intracellularly, probably in lysosomes because an acidic pH maximum in activity exists which acts only on the L isomer.The added polarity and molecular weight brought about by acylation prevents the amines' normally facile entry into cells by simple diffusion, restricting it to an active-transport mechanism.
