USING OF C60 FULLERENE COMPLEXES WITH ANTITUMOR DRUGS IN CHEMOTHERAPY

The literature data and own research results concerning antitumor effect in vitro and in vivo of C60 fullerene and its derivatives, cytostatics, and conjugated systems on their basis, which enable the practical application of C60 in combined chemotherapy for treatment efficacy improving of malignant tumors are generalized. The mechanism of antitumor action of C60 fullerene in combined treatment with cytostatics is based on antioxidant properties of its molecule, thereby reducing toxic side effects of traditional drugs in a body and ability to their transport purposefully into the target cells. The unique structure of C60 enables to modify its surface with chemotherapeutic drugs. Under combined action of the "fullerene C60-chemotherapy drug" conjugate the anti-tumor effects enhancement is observed both in vitro and in vivo, namely quantity reduction of viable tumor cells, tumor reduction etc. Furthermore, protective effects of fullerene C60 and derivatives relatively toxic effects of chemotherapeutic agents in a body were observed. Conjugate auxesis empowers it to be kept longer in a cell and prolong the duration of drug action. Ability of fullerene C60 to selective accumulation provides its using for target drug delivery.
