Abstract: Photothermal therapy(PTT)is a promising avenue for precision cancer treatment. However, the metabolic clearance is a key issue for future clinical applications. In this paper, renal clearance of a cyclodextrin-modified quaterrylene bisimide derivative(QDI-CD)was studied. Importantly, QDI-CD administered to sprague-dawley(SD)rats by intraperitoneal injection was effectively cleared with renal clearance efficiency of(48.74 ± 11.80)% at 12 h after drug injection. In addition, the structure of QDI-CD in urines did not changed under the metabolism.

Key words: photothermal therapy, metabolic clearance, cyclodextrin, quaterrylene
