Design and synthesis of efficient heavy-atom-free photosensitizers for photodynamic therapy of cancer

Chem Commun (Camb). 2020 Sep 29;56(77):11489-11492. doi: 10.1039/d0cc04644b.

Abstract

Novel thiocarbonyl derivatives (NIS and CRNS) with excellent ROS generation abilities are synthesized and studied as potential photosensitizers for one- and two-photon excited photodynamic therapy. In particular, NIS-Me and CRNS display outstanding phototoxicity toward HeLa cells under two-photon excitation (800 nm) with negligible dark toxicity.
