Conjugated 5-fluorouracil with mitochondria-targeting lipophilic cation: design, synthesis and biological evaluation†‡
Abstract
5-Fluorouracil (5-FU) was linked with F16 by vulnerable bonds to selectively target cancer mitochondria which resulted in conjugated compounds, including F16–5-FU, F16–OOC-FU, F16–NHOC-FU and F16–SS-FU. F16–OOC-FU decreased the antiproliferative activity of 5-FU on the nontumor cell line, and the cytotoxicity of F16–SS-FU significantly increased when administered with dithiothreitol (DTT).
