Mitochondrial H(2)S(n)-Mediated Anti-Inflammatory Theranostics.
Kim WY, Won M, Koo S, Zhang X, Kim JS. Kim WY, et al. Nanomicro Lett. 2021 Aug 5;13(1):168. doi: 10.1007/s40820-021-00689-1. Nanomicro Lett. 2021. PMID: 34355274 Free PMC article.
In vitro experiments showed that TA1 selectively reacts with H(2)S(n) to concomitantly release both Rhodol-TPP and indomethacin. Confocal-microscopy imaging of inflammation-induced live cells suggested that TA1 is localized in the mitochondria where the H(2)S …
