-
17-phenyl trinor Prostaglandin F2a diethyl amide
Cayman ChemicalAn F-series PG analog in which the C-1 carboxyl group has been modified to an N-diethyl amide; dialkyl amides such as a 17-p-PGF2α-NEt2 are inert to corneal amidase activity, and are not converted in any detectable amount to the corresponding free acids.
-
Prostaglandin F2a 1,11-lactone
Cayman ChemicalPGF2α 1,11-lactone is a lipid-soluble internal ester of PGF2α. Hydrolysis of the lactone by plasma esterases readily produces free PGF2α in rats and monkeys, but not in humans. PGF2α 1,11-lactone is active as an antifertility agent with greatly reduced vasoactivity compared…
-
11ß-Prostaglandin E2
Cayman Chemical11β-PGE2 is the C-11 epimer of PGE2. It is a moderate inhibitor of PGE2 binding to rat hypothalamic membranes with a Ki value of 53 nM. 11β-PGE2 also stimulates bone resorption in rats at concentrations of 10-8 to 10-6 M which is similar to PGE2. 11β-PGE2 inhibits PGE2 binding to the…
-
13,14-dihydro-15-keto Prostaglandin E2
Cayman ChemicalThe primary metabolite of PGE2 in plasma which is formed through the 15-hydroxy PGDH pathway.
-
ONO-8711
Cayman ChemicalA potent and selective competitive antagonist of the EP1 receptor (Ki = 0.6 and 1.7 nM for human and mouse EP1, respectively); effectively reduces tumor incidence and multiplicity in mouse models of colon, breast, and oral cancer; suppresses pain and acid-induced HCO3- secretion in the stomach.
-
Prostaglandin B2
Cayman ChemicalPGB2 is a non-enzymatic dehydration product resulting from the treatment of PGE2 or PGA2 with strong base. It has weak agonist activity on TP receptors and can increase pulmonary blood pressure in the rabbit at relatively high doses (5 µg/kg).
-
Prostaglandin J2
Cayman ChemicalA dehydration product of PGD2 formed by the elimination of the C-9 hydroxyl group; inhibits platelet aggregation (IC50 ~ 5-10 nM); has antimitotic and antiproliferative effects on a variety of cultured normal cells and tumor cell lines.
