“The concentration that inhibited 50% of prostaglandin biosynthesis (IC50) in the rabbit iris-ciliary body was 9.3 microM. Ebselen also inhibited the formation of 12-hydroxyeicosatetraenoic acid (12-HETE) in rabbit and rat ocular tissues and rabbit platelets.”
“The formation of cyclooxygenase products in rabbit and rat ocular and non-ocular tissues in vitro, detected by radio-thin-layer chromatography, was inhibited in a concentration-dependent manner by ebselen (PZ 51), an anti-inflammatory seleno-organic compound which has glutathione peroxidase and anti-oxidant activities.”
