摘要

"PHOTOSENSITIZING AGENT OR PHARMACEUTICALLY ACCEPTABLE SALT OF THE SAME, PROCESS FOR THE PREPARATION OF THE SAME, PHARMACEUTICAL COMPOSITION, USE OF THE AGENT OR PHARMACEUTICALLY ACCEPTED OF THE SAME METHOD FOR THE INTRODUCTION OF CELLULAR INTRODUCTION PHOTOCHEMIOTEAPEUTIC TREATMENT OF EXTERNAL OR INTERNAL SURFACE DIFFERENCE, OR ANALMALITIES OF THE BODY; PATIENT BODY OR FABRIC FLUID ". The present invention provides photosensitizing agents obtained by reducing a single double bond in the porphyrin macrocycle of a sulfonated porphyrin meso-tetrafenyl, preferably a disulfonated porphyrin mesotetrafenyl as TPPS-2a-. The resulting sulfonated meso-tetrafenyl chlorines include compounds of formula (I)). (where X is -SO-3-H; n, p and q are each independently 0 or 1; and the sum of n, p and q is an integer from 1 to 4, preferably at least 2, as 2 or 4) isomers and mixtures of isomers thereof. The compounds of the invention and their pharmaceutically acceptable salts find special use as photosensitizing agents in photochemical internalization of molecules and photodynamic therapy.
