A Neutral Flavin-Triphenylamine Probe for Mitochondrial Bioimaging under Different Microenvironments

ACS Med Chem Lett. 2023 Nov 22;14(12):1857-1862. doi: 10.1021/acsmedchemlett.3c00446. eCollection 2023 Dec 14.

Abstract

A bioinspired design built around a neutral flavin-triphenylamine core has been investigated for selective mitochondrial bioimaging capabilities in different microenvironments. Significant advantages with respect to long-term tracking, faster internalization, penetrability within the spheroid structures, and strong emission signal under induced hypoxia conditions have been observed, which could offer an alternative to the existing mitotrackers for hypoxia-related biological events.
