Design, synthesis and biological activity evaluation of novel scopoletin-NO donor derivatives against MCF-7 human breast cancer in vitro and in vivo

In this study, eleven new 3- and 7-positions modified scopoletin derivatives (18a-k) were designed, synthesized, and biologically evaluated against human breast cancer cell lines. Most compounds showed improved antiproliferative activity against MCF-7 and MDA-MB-231 cells and weaker cytotoxicity on human breast epithelial cell line MCF-10A than lead compound 5. Among them, compound 18e exhibited the most potent antiproliferative activity against...
