HU 211 is a novel and non-competitive antagonist of NMDA [1].
N-Methyl-D-aspartate (NMDA) is an amino acid derivative that acts as a specific agonist at the NMDA receptor and only binds to and regulates the NMDA receptor.
HU 211 is a novel and non-competitive NMDA antagonist. In culture neurones, HU 211 inhibited NMDA-mediated neurotoxicity in a dose dependent way with EC50 value of 3.8 µM. Also, HU 211 inhibited [3H]MK-801 binding to rat forebrain membranes in a competitive way with Ki value of 11.0 µM [1]. In rat alveolar macrophage cell line and murine peritoneal macrophages, HU 211 inhibited nitric oxide and TNFα production induced by lipopolysaccharide (LPS) [4].
In a global ischemia gerbil model, HU-211 (4 mg/kg) significantly induced neuroprotection in the CA1 subfield of the hippocampus [2]. In the rat with closed head injury (CHI), HU-211 (5 mg/kg) significantly improved neurological severity score (NSS) and slightly reduced edema. In the Morris water maze, HU-211 significantly improved the abilities impaired by CHI [3]. In BALB/c mice injected with 10 mg/kg LPS, HU-211 reduced lethality to 9 and 67%. In Sprague-Dawley rats, HU-211 abolished the hypotensive response induced by LPS [4].
