摘要

In order to search for novel potential agents for the treatment of chronic kidney diseases (CKD), nitric oxide (NO)-releasing derivatives (5a-c) of ferulic acid were synthesized and characterized by MS, 1H NMR, and elementary analysis. They showed different NO-releasing rate in the absence or presence of L-cysteine in vitro. In the adenine induced CKD rats, these compounds revealed reno-protective effect via lowering blood urea nitrogen (BUN), creatinine (Cr) in serum and malondialdehyde (MDA) in kidney, increasing NO and superoxide dismutase (SOD) level in kidney. Among them, 3-methoxy-4-(nitrooxy)ethoxy cinnamic acid (5a) was confirmed to have a higher NO-releasing rate in vitro and better effect in ameliorating adenine-induced kidney damage in rats.
