INTRODUCTION Cell-free plasma hemoglobin is associated with poor outcome in patients with sepsis. Extracellular hemoglobin and secondarily released heme amplify inflammation in the presence of microbial TLR ligands and/or endogenous mediators. Hemopexin, a plasma protein that binds heme with extraordinary affinity, blocks these effects and has been proposed(More)
Malaria is associated with haemolysis and the release of plasma haem. Plasma haem can cause endothelial injury and organ dysfunction, and is normally scavenged by haemopexin to limit toxicity. It was hypothesized that dysregulation of the haem-haemopexin pathway contributes to severe and fatal malaria infections. Plasma levels of haemin (oxidized haem),(More)
It has been hypothesized that peripherally restricted NMDA receptor antagonists may be effective analgesics for osteoarthritis pain. A class of novel quinoxalinedione atropisomers, first discovered for an NMDA receptor antagonist program for the treatment of stroke, was evaluated and further optimized with the goal of finding peripherally restricted NMDA(More)
