ABSTRACT:
Carriers for pharmacologic agents comprise nanoerythrosomes, which are vesicles prepared by the extrusion of red blood cell ghosts, the average diameter of these vesicles is 0.1 .mu.m; the daunorubicin was covalently linked to nanoerythrosomes and the cytotoxicity of daunorubicin conjugated to nanoerythrosomes was assessed on P388D.sub.1 cell line; the results indicated that the cytotoxicity of conjugated daunorubicin was higher than the free daunorubicin, similar results were observed on CDF.sub.1 mice bearing grafted P388D.sub.1 leukemia tumors; daunorubicin-nanoerythrosome conjugates had a higher antineoplastic activity than the free bioactive agent.
