Summary
Human secretory phospholipases A2 have been associated with inflammatory diseases for many years, yet very few truly potent inhibitors of the human enzymes sPLA2 (isoforms IIa, V or X) are known due to a range of problems relating to the lipid nature of substrates, unavailability of enzymes, enzyme assays that do not correlate with in vivo data. Although there remains controversy about which enzyme is responsible in vivo for degrading membrane phospholipids to inflammatory mediators like arachid ....Human secretory phospholipases A2 have been associated with inflammatory diseases for many years, yet very few truly potent inhibitors of the human enzymes sPLA2 (isoforms IIa, V or X) are known due to a range of problems relating to the lipid nature of substrates, unavailability of enzymes, enzyme assays that do not correlate with in vivo data. Although there remains controversy about which enzyme is responsible in vivo for degrading membrane phospholipids to inflammatory mediators like arachidonate, PAF, prostaglandins, leukotrienes, etc. there is a consensus that blockade of phospholipid metabolism would represent a major advance on NSAIDs as antiinflammatory agents. No sPLA2-IIa inhibitor is available yet in man. We aim to create an attractive data package showing proof of concept for a potent new type of antiinflammatory drug. This data will give us an improved negotiating position in our commercialisation of a new drug with potential multi-billion dollar markets as diverse as arthritis, asthma, reperfusion injury, organ transplantation and many other currently intractable human ailmentsRead moreRead less
