The concept of "therapeutic in vivo synthetic chemistry" refers to chemical synthesis in living systems using new-to-nature reactions for the treatment or diagnosis of diseases. This review summarizes our development of therapeutic in vivo synthetic chemistry using glycan-modified human serum albumin (glycoHSA) and utilizing the selective glycan-targeting and metal protective effects of metal catalysts. The four artificial metalloenzymes with glycoHSA provided good cancer treatment results based on on-site drug synthesis and selective cell-tagging strategies. Thus, we propose that therapeutic in vivo synthetic chemistry using glycoHSA as a new modality of therapy or diagnosis is applicable to a wide range of diseases.
