FIELD OF THE INVENTION The present invention relates to tumor recognition photosensitive agent-drug conjugates, and more particularly to having a specific specific activity for tumor tissues, which not only accumulate efficiently in tumor tissues, but also result in cleavage of DEVD peptides by caspase-3 to progenitors. In the form of drug, the drug is locally released, which has the advantage of effectively exerting the efficacy of anticancer drugs with little systemic toxicity. |
