The chemical structure of prostaglandin X, the anti-aggregatory substance derived from prostaglandin endoperoxides, is 9-deoxy-6, 9α-epoxy-Δ5-PGF1α. The stable compound formed when prostaglandin X undergoes a chemical transformation in biological systems is 6-keto-PGF1α. Prostaglandin X is ...
The chemical structure of prostaglandin X (Prostacyclin) The chemical structure of prostaglandin X, the anti-aggregatory substance derived from prostaglandin endoperoxides, is 9-deoxy-6, 6alpha-epoxy-delta5-PGF1alpha. The stable compound formed when prostaglandin X undergoes a chemical transfo... ...
Bioactivation of carcinogens by peroxidases has received increasing attention since the discovery of the oxidation of carcinogens by prostaglandin hydroperoxidase. Benzidine and 3,5,3',5'-tetramethylbenzidine are oxidized by horseradish peroxidase and prostaglandin synthase to two-electron oxidation products ...
Prostaglandin endoperoxide synthase (PGH synthase; EC 1.14.99.1) is a protein of apparently 72 kDa with known primary structure and one heme as prosthetic group (1 ). Its three-dimensional structure...doi:10.1007/978-1-4615-3520-1_14H.-J. Scherer...

Here we report the cryo-electron microscopy structure of GPR101 constitutively coupled to Gs heterotrimer, which reveals unique features of GPR101, including the interaction of extracellular loop 2 within the 7TM bundle, a hydrophobic chain packing-mediated activation mechanism and the structural basis...
Using a zebrafish-based system of human tumour xenograft analysis [22], it was observed that colon carcinoma invasion and migration was inhibited by ENOblock treatment, without producing toxic side effects. Interestingly, the chemical structure for ENOblock was reported in an earlier study of ...
