Abstract:
PURPOSE: Provided is a porphyrin derivative of the formula(1) which is useful as a photosensitizer in photodynamic therapy(PDT) applied to incurable diseases, such as cancer and the like. CONSTITUTION: The porphyrin derivative is represented by the formula(1), wherein R1, R2, R3, R4, R5, R6, R7 and R8 are identical or different each other, and represent hydrogen, an alkyl group or a heteroalkyl group containing a hetero atom; A1, A2, A3 and A4 are identical or different each other, and represent hydrogen, an alkyl group, a heteroalkyl group containing a hetero atom, an alkenyl group, a substituted or unsubstituted aryl group(wherein, a substituent is selected from a hydroxy group and a C1-C6 alkyl group) or a heteroaryl group; the alkyl group and alkenyl group represent a C1-C6 linear or branched hydrocarbon cycle; and the porphyrin derivative can be metalloporphyrin binding to a transition metal containing nickel.
