MECHANOMAGNETIC REACTOR FOR ACTIVATION OF ANTICANCER DRUGS
Mechanomagnetochemical activation can increase the concentration of paramagnetic centers (free radicals) in the anticancer drug, for example, doxorubicin that enables to influence its magnetic properties under external electromagnetic field and improve its magnetic sensitivity and antitumor activity. The principles of design and operation of mechanomagnetic reactor for implementation of this technology which includes mechanomagnetochemical activation and electromagnetic radiation of the drug are described in the paper. The methods of vibration magnetometry, electron paramagnetic resonance spectroscopy and high-performance liquid chromatography were used for studying of doxorubicin mechanomagnetic activation effects. The studies have shown that a generator of sinusoidal electromagnetic wave, working chambers from caprolactam, fluoroplastic or organic materials with metal inserts and working bodies made from steel or agate depending on the required doxorubicin magnetic properties are expedient to use in the designed mechanomagnic reactor. Under influence of mechanomagnetochemical activation doxoru bi cin, which is diamagnetic, acquires the properties of paramagnetic without changing g-factors in the spectra of electron paramagnetic resonance. Mechanomagnetochemical activation of doxorubicin satisfies pharmacopoeia con-di tions according to the results of liquid chromatography that points on perspective of this method using in technology of tumor therapy with nanosized structures and external electromagnetic radiation.
