Abstract

Basic principles of a novel method of cancer treatment are explained. Method is based on the thermal activation of an inactive prodrug encapsulated in magnetoliposomes via Neél and Brown effects of inductive heating of subdomain superparamagnetic particles to sufficiently high temperatures. This principle may be combined with targeted drug delivery (using constant magnetic field) and controlled release (using high-frequency magnetic field) of an activated drug entrapped in magnetoliposomes. Using this method drug may be applied very selectively in the particular site of organism and this procedure may be repeated several times using e.g. stealth magnetoliposomes which are circulating in a blood-stream for several days. Moreover the magnetoliposomes concentrated by external constant magnetic field in tumor vasculature may lead to embolic lesions and necrosis of a tumor body and further the heat produced for thermal activation of a drug enhances the effect of chemotherapy by local hyperthermic treatment of neoplastic cells.
