ANTITUMOR COMPOSITION COMPRISING ASCORBIC ACID AND METAL COMPLEXES OF (NA)PHTHALOCYANINES

摘要

The invention pertains to biology and medicine, specifically, to the suppression of malignant tumour growth. The problem addressed by the invention is that of finding more effective and less toxic agents for suppressing tumour growth. The invention in essence proposes the use of a substance consisting of a cobalt or iron complex with substituted phthalocyanines (I) or naphthalocyanines (II) and of a biogenic reducing agent. In the formulae shown, R = COONa, SO3Na, CH2C5H4N(+)Cl(-), CH2(NH2)2S(+)CH2Cl(-). Use of the proposed agent facilitates effective suppression of a wide range of malignant neoplasms, specifically, suppression of malignant cell proliferation (in vitro), slowing of tumour growth in mice (in vivo), and a significant increase in the life expectancy of the mice by comparison with inter alia the use of a prototype.
