Abstract
A new synthetic derivative, N-alpha-5 (1,6-dihydro-6-oxo-9-purinyl) pentyloxy-carbonyl-L-arginine (PCF-39) has been evaluated in vitro and in vivo in order to clarify its immunopharmacologic profile. In vitro, PCF-39 did not modify spleen cell functions, whereas parenteral administration in mice of 2.5 and 25 mg/kg (50 and 500 micrograms/mouse) induced an increase in spleen and lymph node cellularity that resulted in a significant resistance to the growth of two distinct syngeneic transplanted tumors. These in vivo findings show that PCF-39 is a potent immunotherapeutic agent with an antitumor effect.
