Subsequently, small molecule anti-cancer drugs are directed to the mitochondria for improved therapeutic efficacy. However, simultaneous imaging and impairing mitochondria by a single probe remained a major challenge. To address this, herein Chimeric Small Molecules (CSMs) encompassing drugs, fluorophore and mitochondria homing moiety were designed and synthesized through a concise strategy. Screening of the CSMs in a panel of cancer cell lines (HeLa, MCF7, A549, and HCT-116) revealed that one of the CSMs comprising Indomethacin V exhibited remarkable cervical cancer cell (HeLa) killing (IC<inf>50</inf>=0.97 μM). This lead CSM homed into the mitochondria of HeLa cells within 1 h followed by mitochondrial damage and reactive oxygen species (ROS) generation. This novel Indomethacin V-based CSM-mediated mitochondrial damage induced programmed cell death (apoptosis). We anticipate these CSMs can be used as tools to understand the drug effects in organelle chemical biology in diseased states.falsecancer | drug conjugate | mitochondria | non-steroidal anti-inflammatory drugsArticle1439763315 January 20241e202300603arJournal1WOS:001104363900001
