A novel batch of thiazole-containing mitochondrial targeting agents were designed and synthesized, with D1 exhibiting strong antiproliferative activity and significant mitochondrial inhibition on HeLa cancer cells.
In this study, a novel batch of thiazole-containing mitochondrial targeting agents were designed and synthesized. Four kinds of mitochondrial targeting moieties and six kinds of linkers were designed. Their structures were confirmed by NMR and HR-MS. The screening of antiproliferative activity revealed that most compounds displayed cytotoxicity on HeLa cancer cell. In particular, D1 has an IC50 value of 35.32 mu mol.L-1 against HeLa cell. In addition, cellular respiratory activities were also tested on HeLa cancer cells. D1 had a basal oxygen consumption rate of 8.84 pmol.s(-1).mL(-1). Also, D1 inhibited the mitochondrial respiration of HeLa cell significantly at 5 mu mol.L-1, as well as a complete inhibitory of oxygen consumption for cellular ATP coupling. Furthermore, the pKa, logP, and logD under different pH conditions of all the compounds were calculated by the ACD/ Percepta-PhysChem Suite, and the results manifested the correlation between physicochemical properties and chemical activity of compounds. The results identify D1 as a promising mitochondria inhibitor and anticancer agent with appropriate physicochemical properties.
