The cordycepin derivative IMM-H007 improves endothelial dysfunction by suppressing vascular inflammation and promoting AMPK-dependent eNOS activation in high-fat diet-fed ApoE knockout mice. Eur J Pharmacol. 2019 Feb 28;: Authors: Wang MJ, Peng XY, Lian ZQ, Zhu HB Abstract 2',3',5'-Tri-O-acetyl-N6-(3-hydroxyphenyl) adenosine, a cordycepin derivative that is also known as IMM-H007, is a new adenosine analogue and anti-hyperlipidaemic drug that was developed in our laboratory. It has been previously reported to alleviate atherosclerosis by regulating blood lipid levels. The purpose of the current study was to determine the protective effects of IMM-H007 on endothelial function and vascular inflammation independent of its lipid-lowering effect. Vascular reactivity was determined using a pressure myography system-120CP. Vascular inflammation was assessed to quantify leukocyte-endothelial adhesion in the mesenteric microcirculation. Relative levels of endothelial nitric oxide synthase(eNOS)activity were detected using a fluorescent nitric oxide(NO)probe, and NO production was detected using Griess reagent. Atherosclerotic plaques were evaluated with en face and cross section analyses. Here, IMM-H007 improved endothelial dysfunction through a mechanism independent of its lipid-lowering effect. IMM-H007 suppressed vascular inflammation both in the initial stage and during the progression of atherosclerosis. The in vitro study using ...
