DOTAderivatives are phenoxy derivatives of cyclic Tosamide;Direct nitrification;It is more convenient to add nitro group after removing the protection of lithium aluminium hydride.
DOTA tert-butyl ester is a phenyl derivative of cycloteramide; it can be directly nitrated; it is more convenient to add nitro after deprotection of lithium aluminum hydride.
PSMA617-TCMC is a derivative of PSMA-617 with structure modification, in which the caroboxy groups in DOTA ring is replaced by TCMC macrocycle. PSMA-617 is a ligand used to make 177Lu-PSMA-617, which is a radioactive molecule to fight cancer.
