Novel furoxan-based nitricoxide (NO) releasing derivatives of oleanolic acid (OA) were synthesized for potential therapy of liver cancers. Six compounds produced high levels of NO in human hepatocellular carcinoma (HCC) cells and exhibited strong cytotoxicity selectively against HCC in vitro. Treatment with 8b or 16b significantly inhibited the growth of HCC tumors in vivo. These data provide a proof-in-principle
A series of nitric oxide (NO)-releasing glycosyl derivatives (2–14) of oleanolic acid were synthesized to improve the aqueous solubility and cytotoxicity of the parent compound 1. Derivative 3 exhibited better solubility and strong cytotoxicity against human hepatocellularcarcinoma (HCC) in vitro. Furthermore, 3 displayed low acute toxicity to mice and significantly inhibited the growth of HCC tumors
