Abstract: The present invention relates to a novel anti-miRNA single-stranded nucleic acid maleimide derivative, which comprises an anti-miRNA single-stranded nucleic acid having a nucleic acid sequence complementary to a nucleic acid sequence of an miRNA. Further, the present invention provides an anti-miRNA single-stranded nucleic acid-serum albumin conjugate in which serum albumin is covalently bonded to the anti-miRNA single-stranded nucleic acid maleimide derivative via the maleimide group.

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.
