Effects of stable PGH2 analogues and various prostaglandins on PGE synthase activity [1]
Several PGs and close analogues of the PGH2 substrate were also assayed for their effects on PGE synthase activity. U-44069 and U-46619 are essentially identical to PGH2 except that each oxygen of the endoperoxide is sequentially replaced by a methylene group. These stable analogues caused only low levels of inhibition of PGE synthase (<30%) at 10 μM (Fig. 3) and thus were considerably less potent inhibitors than PUFAs. U-51605, where the endoperoxide of PGH2 is replaced by a diazo group, showed superior inhibitory activity when compared with either U-44069 or U-46619 with 70% inhibition at 10 μM. Interestingly, U-51605 also lacks the highly conserved hydroxy group at C15 found among most PGs. PGE2, 15(R)-PGE2, PGE3, PGF2α, thromboxane B2 (TXB2), PGJ2, and Δ12-PGJ2 had little effect (<30%) when tested at a concentration of 10 μM. The lack of inhibition by PGE2 suggests that the reaction is not sensitive to product inhibition under the current assay conditions. |

| Additional Infomation |
Prostaglandin E2 synthase (PGE synthase) is one of the membrane-associated proteins in the eicosanoid and glutathione metabolism (MAPEG) family of microsomal enzymes and constitutes a novel inducible enzyme involved in inflammation and pyretic responses. We report, using a reversed-phase HPLC assay for the production of tritiated prostaglandin E2 (PGE2) by membranes from cells overexpressing human microsomal PGE synthase, that PGE synthase activity is inhibited effectively by 15-deoxy-Δ12,14-prostaglandin J2 and arachidonic acid. The anti-inflammatory compound 15-deoxy-PGJ2 was considerably more potent at inhibiting PGE synthase (
μM) than the closely related PGJ2 or Δ12-PGJ2, or the reaction product PGE2. Arachidonic acid, docosahexaenoic acid, and eicosapentaenoic acid inhibited PGE synthase with a similar potency (
μM) and were more potent inhibitors than various fatty acid analogues. The present results on the inducible PGE synthase extend observations on the ability to bind arachidonic acid to another member of the MAPEG family, and also suggest a novel mechanism of action for the anti-inflammatory effects of DHA, EPA, and 15-deoxy-PGJ2.
