The present invention relates to the field of medicine, particularly to oncology and provides a pharmaceutical composition intended for the photodynamic therapy of malignant tumors, comprising a therapeutically effective amount of at least one of derivatives of fullerene C
60
selected from the group consisting of a compound in which a fullerene C
60
molecule covalently binds to one molecule of an amino acid or a dipeptide, or its pharmaceutically acceptable derivative, or a complex of a compound with biocompatible synthetic polymers or biopolymers and tetrapyrroles, or a conjugate of a compound with an amino compound. Said compounds after accumulation in cells and photoirradiation transform molecular oxygen into singlet oxygen, generate free radicals, and also trigger biological processes inhibiting the vital activity of tumor cells. The present invention also relates to a method of photodynamic therapy of malignant tumors, in which the pharmaceutical composition of the present invention is used as the photosensitizer.
本发明涉及医学领域,尤其是肿瘤学,并提供了一种用于恶性肿瘤光动力疗法的药物组合物,包括治疗有效量的富勒烯C60衍生物之一,所述衍生物选自以下组中的化合物:一种富勒烯C60分子共价结合到一分子氨基酸或二肽的化合物,或其药学上可接受的衍生物,或一种与生物相容的合成聚合物或生物聚合物和四吡咯簇合物的化合物,或一种与氨基化合物簇合的化合物。在细胞中积累后,这些化合物经过光照作用会将分子氧转化为单线态氧,产生自由基,并触发抑制肿瘤细胞生命活动的生物过程。本发明还涉及一种用于恶性肿瘤光动力疗法的方法,其中使用本发明的药物组合物作为光敏剂。
