Induction of murine erythroleukemia cell differentiation by proteinases is inhibited by aromatic poly-amidines.
The effects of the tetra benzamidine serine-proteinase inhibitor 1,3-di-(p-amidinophenoxy) -2,2- bis- (p-amidinophenoxymethyl)propane (TAPP-H) and related compounds, including halo-derivatives, were determined on the erythroid differentiation of murine erythroleukemic cells induced by trypsin and kallikrein. These aromatic poly-amidines and their halo derivatives were found to be strong inhibitors of both trypsin and kallikrein mediated induction of commitment of MEL cells to erythroid differentiation, hemoglobin synthesis and accumulation, globin mRNA production. No inhibitory effects were detected by treating proteinase-induced MEL cells with benzamidine. Only slight inhibitory activity was found after treatment of trypsin-induced MEL cells with other antiproteinase compounds widely used in the control of proteinase-dependent functions, including leupeptin, antipain and Bowman-Birk proteinase inhibitor. MEL cells induced to erythroid differentiation by proteinases could be proposed as an experimental system to test the biological activity of proteinase inhibitors.
