<title>First experience of photodithazine clinical application for photodynamic therapy of malignant tumors</title>

Abstract

In 1998 a new second-generation photosensitizer was introduced in Russia - a chlorine derivative named Photodithazine - water-soluble preparation with absorption peak at 668 nm. This novel preparation has passed pre- clinical in vitro and in vivo studies. In 1999 a limited series of clinical testing of photodynamic therapy with photodithazine has been performed in the State Research Center for Laser Medicine of Russian Ministry of Public Health.
