Disease

PAFA_HUMAN Defects in PLA2G7 are the cause of platelet-activating factor acetylhydrolase deficiency (PAFAD) [MIM:614278. An enzymatic deficiency that results in exacerbated bodily response to inflammatory agents. Asthmatic individuals affected by this condition may manifest severe respiratory symptoms.^[1] ^[2] ^[3] ^[4] ^[5] Defects in PLA2G7 are a cause of susceptibility to asthma (ASTHMA) [MIM:600807. The most common chronic disease affecting children and young adults. It is a complex genetic disorder with a heterogeneous phenotype, largely attributed to the interactions among many genes and between these genes and the environment. It is characterized by recurrent attacks of paroxysmal dyspnea, with weezing due to spasmodic contraction of the bronchi. Note=PLA2G7 variants can be a risk factor for the development of asthma and PLA2G7 may act as a modifier gene that modulates the severity of this disease.^[6] Defects in PLA2G7 are a cause of susceptibility to atopic hypersensitivity (ATOPY) [MIM:147050. A condition characterized by predisposition to develop hypersensitivity reactions. Atopic individuals can develop eczema, allergic rhinitis and allergic asthma.^[7]

Function

PAFA_HUMAN Modulates the action of platelet-activating factor (PAF) by hydrolyzing the sn-2 ester bond to yield the biologically inactive lyso-PAF. Has a specificity for substrates with a short residue at the sn-2 position. It is inactive against long-chain phospholipids.

Publication Abstract from PubMed

Lp-PLA2 has been explored as a target for a number of inflammation associated diseases, including cardiovascular disease and dementia. This article describes the discovery of a new fragment derived chemotype that interacts with the active site of Lp-PLA2. The starting fragment hit was discovered through an X-ray fragment screen and showed no activity in the bioassay (IC50 > 1 mM). The fragment hit was optimized using a variety of structure-based drug design techniques, including virtual screening, fragment merging, and improvement of shape complementarity. A novel series of Lp-PLA2 inhibitors was generated with low lipophilicity and a promising pharmacokinetic profile.
