15-keto-Prostaglandin E2
Based on 1 Customer Validation
15-keto-Prostaglandin E2 (15-keto-PGE2) is an endogenous PGE2 metabolite. 15-keto-Prostaglandin E2 inhibits STAT3 activation by binding to the Cys259 residue of STAT3. 15-keto-Prostaglandin E2 binds to and stabilizes EP2 and EP4 receptors. 15-keto-Prostaglandin E2 inhibits the growth and progression of breast cancer cells. 15-keto-Prostaglandin E2 activates PPAR-γ and promotes fungal growth. 15-keto-Prostaglandin E2 disrupts glomerular vascularization during zebrafish development and reduces the surface area of the glomerular filtration barrier.

15-keto-PGE2 (1 μM; 20 min) binds to and stabilizes HiBiT-tagged hEP2 receptors on the cytoplasmic membrane of MMY28 yeast[1].
15-keto-PGE2 (10-20 μM; 24 h) dose-dependently inhibits the clonogenic capacity of MDA-MB-231 cells[3].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
15-keto-Prostaglandin E2 (10 μM; immersion) significantly increases the fungal load of Cryptococcus neoformans Δplb1-GFP in zebrafish larvae, reaching 1.56 times that of the control group[2].
15-keto-Prostaglandin E2 (70-140 μg/kg; subcutaneous injection; administered daily for 4 consecutive weeks) dose-dependently inhibits the growth of MDA-MB-231 breast cancer xenografts in BALB/c nude mice[3].

Animal Model:Tg[wt1b:eGFP] (embryos; early treatment: 6-48 hpf; late treatment: 72-96 hpf)[1]
-
Dosage:500 μM
-
Administration:immersion; continuous
-
Result:Caused mild yolk edema, with 80% of embryos showing affected pronephros structure plus yolk edema.
Resulted in 20% of glomeruli exhibiting impaired podocyte intercalation and failed glomerular cleft formation at 48 hpf (early treatment).
Induced podocyte clustering at the embryo midline and impaired podocyte intercalation around glomerular capillaries, affecting ~83% of glomeruli (late treatment).
Reduced glomerular surface area significantly in treated embryos compared to controls, while glomerular volume showed a non-significant numerical decrease (late treatment).
Reversed all morphological defects, restoring glomerular surface area to control levels when combined with EP2/EP4 receptor antagonists.
-
Animal Model:BALB/c (nu/nu) athymic nude mice (female, 7 weeks old)[3]
-
Dosage:70 μg/kg; 140 μg/kg
-
Administration:s.c.; daily; 4 weeks
-
Result:Retarded tumor growth significantly in both treatment groups, with average tumor volume reduced in a dose-dependent manner.
Markedly decreased STAT3 phosphorylation (P-STAT3Y705) in tumor tissue at 140 μg/kg, as measured by Western blot and immunohistochemical analysis.
Caused no body weight loss or signs of toxicity.
Showed decreased tumor density in treated mice compared to controls via H&E staining.
