Abstract
It was found that irradiation of aqueous solution of aluminum sulphophthalocyanine (SnPcAl) by light with wavelength of 805 nm in the presence of sodium ascorbate results in photodynamic type I effect. S2PcAl in adsorbed state on proteins or polysaccharide structures was shown to possess rather intense long wavelength absorption band in the NIR spectral region. The comparative tests of SnPcAl with sodium ascorbate on mice with Ehrlich carcinoma and leucosis P-388 showed that photodynamic efficiency in the case of NIR irradiation (790 nm) is not lower than using visible irradiation (675 nm).
