The purpose of this review is to call attention in the use of chlorophyll-a and bacteriochlorophyll-a to develop more than 600 photosensitizers (lambda (max) 660 nm-800 nm) during the last 15 years (1990-2005) at the Photodynamic Therapy Center, Roswell Park Cancer Institute, Buffalo. This article mainly includes the chemistry, preclinical results, and brief clinical data of some of the most effective photosensitizers. The utility of the tumor-avid photosensitizers in developing multimodality agents (imaging and therapy) is also presented.
