    摘要： This invention describes a first report on the synthesis of certain 124I-labelled photosensitizers related to chlorines and bacteriochlorins with long wavelength absorption in the range of 660-800 nm. In preliminary studies, these compounds show a great potential for tumor detection by positron emission tomography (PET) and treatment by photodynamic therapy (PDT). The development of tumor imaging or improved photodynamic therapy agent(s) itself represent an important step, but a dual function agent (PET imaging and PDT) provides the potential for diagnostic body scan followed by targeted therapy.

Preferably the photosensitizer is a tumor avid tetrapyrollic photosensitizer, e.g. a porphyrin, chlorin or bacteriochlorin, e.g. pheophorbides and pyropheophorbides. Such conjugates have extreme tumor avidity and can be used to inhibit or completely destroy the tumor by light absoption. The integrin is usually αvβ3, α5β1, αvβ5, α4β1, or α2β1. Preferably, the antagonist is an RGD peptide or another antagonist that may be synthetic such as a 4-{2-(3,4,5,6-tetra-hydropyrimidin-2-ylamino)ethyloxy}-benzoyl]amino-2-(S)-amino-ethyl-sulfonylamino group. Such compounds provide tumor avidity and imaging ability thus permitting selective and clear tumor imaging.
