Photodynamic activity of dibiotinylated aluminum sulfophthalocyanine in vitro and in vivo

J Photochem Photobiol B. 2005 Jul 1;80(1):57-64. doi: 10.1016/j.jphotobiol.2004.12.008. Epub 2005 Apr 18.

Abstract

The photodynamic activity of dibiotinylated aluminum sulfophthalocyanine was studied in vitro and in vivo. Dibiotinylated aluminum sulfophthalocyanine provided enhanced phototoxic action on OAT-75 cell monolayers as compared with the parent drug. Photodynamic therapy of mice with Ehrlich carcinoma using dibiotinylated aluminum sulfophthalocyanine (0.25 mg/kg) resulted in enhanced inhibition of tumor growth, pronounced vascular damage (thrombosis and destruction of vascular walls) and eventual tumor necrosis.
