常见问题列表
吸入曲前列素钠(一种前列环素类似物)是最近获得FDA批准用于治疗致命性孤儿疾病的药物:肺动脉高压(PAH)。与安慰剂相比,曲前列环素可保留窦状内皮细胞衬里并减少移植后早期的血小板沉积。安慰剂组的肝组织血流明显受损,而曲前列环素维持血流量与正常水平相似。前列腺素治疗显着增加内皮细胞集落形成细胞与间充质干细胞在裸鼠移植的基质胶中的血管形成能力。在间充质干细胞中沉默VEGF-A基因也会阻断曲前列环素的促血管生成作用。曲前列环素在提高小鼠和人类造血干细胞和祖细胞中的细胞内cAMP水平方面最有效。与常氧小鼠相比,用曲前列环素治疗显着减少细胞募集。曲前列环素还可降低右心室收缩压并略微减少血管重塑,但无法逆转右心室肥厚。
Target | Value |

(Cell-free assay) | 3.6 nM(Ki) |
DP1
(Cell-free assay) | 4.4 nM(Ki) |
IP
(Cell-free assay) | 32 nM(Ki) |
Treprostinil has high affinity for the DP1, EP2 and IP receptors (K i =4.4, 3.6 and 32 nM, respectively), low affinity for EP1 and EP4 receptors and even lower affinity for EP3, FP and TP receptors. Activation of IP, DP1 and EP2 receptors, as with treprostinil, can all result in vasodilatation of human pulmonary arteries.Treprostinil inhibits viability of cultured endothelial colony forming cells. Endothelial colony forming cells proliferation is stimulated by conditioned media from Treprostinil pretreated mesenchymal stem cells.
Inhaled treprostinil sodium, a prostacyclin analog, is the most recent agent to receive FDA approval for the treatment of a fatal orphan disease: pulmonary arterial hypertension (PAH). Treprostinil preserves the sinusoidal endothelial cell lining and reduces platelet deposition early post-transplantation compared to placebo. Hepatic tissue blood flow is significantly compromised in the placebo group, whereas treprostinil maintains blood flow similar to normal levels.Treprostinil treatment significantly increases the vessel-forming ability of endothelial colony forming cells combined with mesenchymal stem cells in Matrigel implanted in nude mice. Silencing VEGF-A gene in mesenchymal stem cells also blocks the pro-angiogenic effect of Treprostinil. Treprostinil is most efficacious in raising intracellular cAMP levels in murine and human hematopoietic stem and progenitor cells. Treatment with Treprostinil significantly reduces the recruitment of cells compared to normoxic mice. Treprostinil also reduces right ventricular systolic pressure and slightly reduces the vascular remodelling but fails to reverse the right ventricular hypertrophy.
