Использование комплексов фуллерена с 6 0 с противоопухолевыми препаратами в химиотерапии

Abstract

Обобщены данные литературы и результаты собственных исследований противоопухолевого действия in vitro и in vivo фуллерена С 60 и его производных, цитостатиков, а также конъюгированных комплексов на их основе, которые дают возможность применять его в комбинированной химиотерапии для повышения эффективности лечения злокачественных новообразований. Механизм противоопухолевого действия фуллерена С 60 в комбинированном применении с цитостатиками базируется на антиоксидантных свойствах его молекулы, что способствует снижению побочного токсического действия традиционных препаратов в организме, и способности целенаправленно транспортировать их в клетки-мишени. Уникальная структура фуллерена С 60 позволяет модифицировать его поверхность химиотерапевтическими препаратами. При комбинированном действии конъюгата «фуллерен С 60-химиопрепарат» наблюдается усиление противоопухолевых эффектов как в условиях in vitro , так и in vivo , в частности снижение количества жизнеспособных опухолевых клеток, уменьшение размера опухоли и т. д. Кроме того, обнаружены защитные эффекты фуллерена С 60 и его производных относительно токсического действия химиопрепаратов в организме. Увеличение размера конъюгата дает ему возможность дольше удерживаться в клетке и увеличивать длительность действия препарата. Способность молекул фуллерена С 60 к избирательному накоплению позволяет использовать его для таргентной доставки лекарств.

The literature data and own research results concerning antitumor effect in vitro and in vivo of C 60 fullerene and its derivatives, cytostatics, and conjugated systems on their basis, which enable the practical application of C 60 in combined chemotherapy for treatment efficacy improving of malignant tumors are generalized. The mechanism of antitumor action of C 60 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 C 60 enables to modify its surface with chemotherapeutic drugs. Under combined action of the «fullerene C 60chemotherapy 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 C 60 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 C 60 to selective accumulation provides its using for target drug delivery.
