PGE synthase

Prostaglandin E synthase

PGE synthase (Prostaglandin E synthase), which converts cyclooxygenase (COX)-derived prostaglandin H2 (PGH2) to PGE2, is known to comprise a group of at least three structurally and biologically distinct enzymes. There are membrane-associated PGES (mPGES)-1, mPGES-2, and cytosolic PGES (cPGES).

mPGES-1 is a perinuclear protein that is markedly induced by proinflammatory stimuli and downregulated by anti-inflammatory glucocorticoids as in the case of COX-2. It is functionally coupled with COX-2 in marked preference to COX-1. mPGES-2 is synthesized as a Golgi membrane-associated protein, and the proteolytic removal of the N-terminal hydrophobic domain leads to the formation of a mature cytosolic enzyme. This enzyme is rather constitutively expressed in various cells and tissues and is functionally coupled with both COX-1 and COX-2. cPGES is constitutively expressed in a wide variety of cells and is functionally linked to COX-1 to promote immediate PGE2 production.

    Zaloglanstat
    Inhibitor 98.50%
    Zaloglanstat (ISC-27864; GRC-27864) is a selective, orally active microsomal mPGES-1 inhibitor. Zaloglanstat has an IC50 of 5 nM for human mPGES-1 without significant inhibitory effect on COX-1/2 (IC50 >10 μM).

Zaloglanstat inhibits IL-1β-induced PGE2 release in A549 cells and human synovial fibroblasts in vitro. Zaloglanstat inhibits PGE2 release in pig and dog whole blood with IC50s ??of 161 nM and 154 nM, respectively. Zaloglanstat can be used in the study of asthma, osteoarthritis, and neurodegenerative diseases.

Pheophytin a also scavenges free radicals, reduces ferric ions, and exhibits cytotoxic activity against breast cancer cells. Pheophytin a effectively inhibits LPS-induced production of nitric oxide, prostaglandin E2, NOS2 and COX-2, as well as various pro-inflammatory cytokines, by downregulating the transcription levels of inflammatory mediators and blocking the ERK1/2 and STAT-1 pathways. In a low nerve growth factor environment, Pheophytin a also enhances ERK1/2 phosphorylation and synergistically promotes neurite outgrowth through MAPK pathway.
