Dienogest (STS-557) 一种口服有效的和具有选择性的孕酮受体激动剂,能有效减少COX-2、mPGES-1和芳香化酶的基因表达。Dienogest 还能抑制PGE2合成酶的 mRNA 和蛋白表达,以及NF-κB的激活。Dienogest 可用于子宫内膜异位症,更年期和月经过多的研究。
生物活性 | Dienogest (STS-557) is an orally active and selectiveprogesterone receptor agonistthat effectively reduces the gene expression ofCOX-2,mPGES-1andaromatase. Dienogest also inhibits the mRNA and protein expression ofPGE2synthase and the activation ofNF-κB. Dienogest can be used in studies of endometriosis, menopause and menorrhagia[1][2]. |
体外研究 (In Vitro) | Dienogest (0.01-1 μM; 24 h) inhibits PGE2production via inhibition of PGE2synthase gene expressions with the concomitant inhibition of NF-κB activity in a spheroid culture[1]. Dienogest (0.1 μM; 24 h) inhibits aromatase expression gene along with COUP-TFII mRNA expression in a PGE2-independent manner[1].
Cell Viability Assay[1] Cell Line: | EM-PR cells | Concentration: | 0.01-1 μM | Incubation Time: | 24 h | Result: | Inhibited PGE2production and suppressed NF-κB binding activity in the spheroid culture. |
Cell Viability Assay[1] Cell Line: | EM-PR cells | Concentration: | 0.1 μM | Incubation Time: | 24 h | Result: | Decreased the mRNA expression of the PGE2synthases COX-2 and mPGES-1 compared with the respective control. Inhibited aromatase mRNA expression and increased the expression of COUP-TFII mRNA level. |

体内研究 (In Vivo) | Dienogest (1 mg/kg; p.o.; once daily for 14 days) regulates angiogenesis in ectopic endometrial lesions in rat endometrial autograft model[2].
Animal Model: | Female Wistar rats (8 to 10-week-old; 180-220 g; rat endometrial autograft model)[2]. | Dosage: | 1 mg/kg | Administration: | Oral administration; once daily for 14 days. | Result: | Showed significant suppression of angiogenesis of endometrial autografts, as indicated by the reduced size of the microvascular network and decreased microvessel density. Significantly reduced the level of perivascular α-smooth muscle actin within endometrial grafts. |
