13,14-dihydro-15(R)-Prostaglandin E1 (13,14-dihydro-15(R)-PGE1)为13,14-二氢-PGE1的同分异构体，特点在于其C-15位的羟基呈R构型，非自然形态。

Prostaglandin E1 (PGE1), though not predominantly found in nature, plays a significant role in clinical treatments, addressing conditions such as peripheral occlusive vascular disease, erectile dysfunction, and neonatal cardiology issues. The metabolism of PGE1 primarily begins with the oxidation at C-15, producing 13,14-dihydro-15-keto PGE1 as its major metabolite. Alternatively, inhibiting this pathway or overwhelming it with too much PGE1 could potentially enhance the production of 2,3-dinor metabolites, like 2,3-dinor PGE1, though their biological activities remain unreported. Cayman Chemical stands out as a prominent provider of prostaglandins and their metabolites, uniquely manufacturing 2,3-dinor PGE1.

AS1940477 is p38 MAPK inhibitor. AS1940477 inhibited the enzymatic activity of recombinant p38α and β isoforms but showed no effect against other 100 protein kinases including p38γ and δ isoforms. In human peripheral blood mononuclear cells, AS1940477 inhibited lipopolysaccharide (LPS)- or phytohemagglutinin A (PHA)-induced production of proinflammatory cytokines, including TNFα, IL-1β, and IL-6 at low concentrations (LPS TNFα, IC(50)=0.45n M; PHA TNFα, IC(50)=0.40 nM). In addition, equivalent concentrations of AS1940477 that inhibited cytokine production also inhibited TNFα- and IL-1 β-induced production of IL-6, PGE(2), and MMP-3 in human synovial stromal cells. AS1940477 was also found to potently inhibit TNF production in whole blood (IC(50)=12 nM) and effectively inhibited TNFα production induced by systemically administered LPS in rats at less than 0.1mg kg (ED(50)=0.053 mg kg) with an anti-inflammatory effect lasting for 20h after oral administration. Overall, this stu......

AF3442 is a potent and selective mPGES-1 inhibitor (microsomal prostaglandin (PG) E synthase-1). AF3442 caused a concentration-dependent inhibition of PGE(2) in human recombinant mPGES-1 with an IC(50) of 0.06microM. AF3442 is a selective mPGES-1 inhibitor which reduced monocyte PGE(2) generation also in the presence of plasma proteins. Pharmacological inhibition of mPGES-1 did not translate into redirection of PGH(2) metabolism towards other terminal PG synthases in monocytes. The functional relevance of this observation deserves to be investigated in vivo.

19(R)-Hydroxylated prostaglandins (PGs) are present at µg ml concentrations in the semen of some mammalian species, notably primates, with the majority being from the PGE series and featuring a 15(S),19(R) hydroxyl stereochemistry. These compounds are also observed in marsupials' seminal plasma, where F-type 1 and 2-series compounds are predominant. The 15(R)-hydroxy epimer represents the inverse or unnatural isomer at C-15 for these 19-hydroxylated PGs. Although the biological function of 19(R)-hydroxylated PGs remains unclear, 19(R)-hydroxylation in the F-series leads to a notable reduction in receptor-mediated biological activity in certain assays.
