Abstract:
Disclosed is a tumor-targeting photosensitizer-drug conjugate, more particularly to one which exhibits superior specific activity for a tumor tissue, is effectively accumulated in the tumor tissue and exhibits the medicinal effect of an anticancer agent with little systemic toxicity as a DEVD peptide is cleaved by caspase-3 and released topically from a prodrug form.

Claim (Index 11):
The method for preparing a photosensitizer-drug conjugate according to  claim 9 , wherein, in a) of preparing the substituted peptide, the carboxyl hydrogen of the side chain of the peptide comprising SEQ ID NO 1 that can be cleaved by caspase is substituted with the allyl group, the amino hydrogen of the side chain is substituted with the allyloxycarbonyl group, and the N-terminal amine group is protected with an acetyl group.
