Current molecular design of intelligent drugs and imaging probes targeting tumor-specific microenvironments

Abstract

To address the specific challenges of cancer therapy and diagnosis, a number of approaches have been advocated for the development of tumor-targeting antitumor drugs/prodrugs and non-invasive tumor molecular imaging probes. These intelligent drugs and probes are constructed from multi-functional molecular systems. This review focuses on the molecular design of drugs and imaging probes that target tumor-specific microenvironments such as angiogenesis and hypoxia.
