SC-19220
目录号 : KCM12290 CAS No. : 19395-87-0 纯度 : ≥96%
The prostaglandin E (PGE) receptor EP is involved in triggering PGE-mediated pain, neuronal survival and growth as well as the suppression of tumor metastasis. SC-19220 is a dibenzoxazepine that acts as a selective antagonist of PGE at the EP receptor. At doses between 0.3-300 µM, SC-19220 acts as a competitive antagonist of PGE-induced smooth muscle contractions of guinea pig ileum and stomach. SC-19220 also acts as a PGE antagonist in the EP receptor-mediated contraction of guinea pig trachea. SC-19220 displaces radiolabeled PGE from the cloned human EP receptor with an IC of 6.7 µM and exhibits no binding at the human EP receptor. It binds with apparent low affinity to the cloned mouse EP receptor expressed in CHO cells. In a model of bone resorption, 3-150 μM SC-19220 inhibited both 1,25 dihydroxy vitamin D- and PGE-stimulated osteoclastogenesis in mouse osteoclast precursors. Antagonism of EP with 1 μM SC-19220 has been shown to promote metastasis in a mouse model of metastatic breast cancer. In a rodent model of Parkinson’s disease, 1.5 μM SC-19220 prevented PGE-mediated loss of dopaminergic neurons from rat substantia nigra.

生物活性

SC-19220 is a prostaglandin E2 receptor EP1 antagonist. SC-19220 blocks functional EP1 receptor activation, and RANK/RANKL signaling pathway. SC-19220 inhibits osteoclast formation and bone resorption by pre-existing osteoclasts. SC-19220 can be used for the research of osteoporotic disorders, inflammatory bone resorption.

SC-19220 (3-150 µM; 8 days) dose-dependently inhibits osteoclast formation and bone resorption induced by 1,25(OH)2D3 and PGE2 in mouse bone marrow cell cultures, achieving complete inhibition at a concentration of 75 µM.
SC-19220 (75 µM; 4 days) inhibits 1,25(OH)2D3-induced osteoclast formation and bone resorption in mouse bone marrow cell cultures.
SC-19220 (75 µM; 1 day) directly inhibits the bone resorption activity of isolated Wistar rat osteoclasts without reducing their number after 1 day of incubation.
SC-19220 (30-150 µM; 7 days) does not inhibit granulocyte/macrophage colony formation induced by GM-CSF in mouse bone marrow cell cultures but instead mildly enhances colony formation.
SC-19220 (75 µM; 8 days) can inhibit the formation of osteoclasts and bone resorption induced by IL-11, IL-6, and PTH in a mouse osteoblast-marrow cell co-culture system.
SC-19220 (5-25 μg/mL; 6-7 days) dose-dependently inhibited PGE2- or 11-deoxy-PGE1- or RANKL/M-CSF-induced osteoclast formation in mouse bone marrow cell culture systems, with the 25 μg/mL concentration nearly completely eliminating the formation of TRACP+ cells.
SC-19220 (5-25 μg/mL; 24 hours) does not alter the expression of RANKL mRNA in PGE2-induced primary mouse calvarial osteoblasts.
SC-19220 (5-25 μg/mL; 1-2 days) dose-dependently reduced mRNA and protein expression of RANK and c-Fms in mouse bone marrow macrophages treated with M-CSF and RANKL, with the highest inhibitory effect observed at a concentration of 25 μg/mL.
SC-19220 (5-25 μg/mL; 2 days) dose-dependently reduced the expression of c-Src protein in mouse bone marrow macrophages treated with M-CSF and RANKL.
SC-19220 (5-25 μg/mL; 1 day) dose-dependently reduced NFAT2 mRNA and protein expression in mouse bone marrow macrophages treated with M-CSF and RANKL, with the strongest inhibitory effect observed at 25 μg/mL after 1 day of incubation .
