体外研究 (In Vitro) |
曲前列环素对 DP1、EP2 和 IP 受体具有高亲和力(Ki 分别为 4.4、3.6 和 32 nM),对 EP1 和 EP4 受体亲和力低,对 EP3、FP 和 TP 受体亲和力更低。与曲前列环素一样,IP、DP1 和 EP2 受体的激活均可导致人肺动脉血管舒张[1]。曲前列环素抑制培养的内皮集落形成细胞的活力。来自曲前列环素预处理的间充质干细胞的条件培养基刺激内皮集落形成细胞增殖[5]。

体内研究 (In Vivo) |
吸入曲前列环素钠是一种前列环素类似物,是最新获得 FDA 批准用于治疗致命孤儿疾病:肺动脉高压 (PAH) 的药物[2]。与安慰剂相比,曲前列环素可保留窦内皮细胞内层并减少移植后早期血小板沉积。安慰剂组肝组织血流明显受损,而曲前列环素则维持与正常水平相似的血流[3]。曲前列环素治疗显着增加裸鼠基质胶中内皮集落形成细胞联合间充质干细胞的血管形成能力。沉默间充质干细胞中的 VEGF-A 基因也会阻断曲前列环素的促血管生成作用[4]。曲前列环素在提高小鼠和人类造血干细胞和祖细胞的细胞内 cAMP 水平方面最有效[5]。与常氧小鼠相比,曲前列环素治疗显着减少了细胞的募集。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[6]。

细胞实验 |
将来自人类或小鼠的造血干细胞和祖细胞在 37°C 下在载体存在下或与 10 μM 曲前列环素和 30 μM 毛喉素联合培养一小时和二十四小时。细胞凋亡试剂盒用于在 4°C 下用磷酸盐缓冲盐水洗涤细胞后对细胞进行外化磷脂酰丝氨酸染色 [5]。

动物实验 |
Rats: For the study, male Lewis rats weighing between 200 and 300 g are employed. 24 hours prior to hepatectomy, donor animals are given treprostinil or a placebo, and the corresponding recipient animal receives the same care until the moment of sacrifice. Treatment is invisible to the surgeon. To study what happens right after IRI, recipients are sacrificed 1, 3, 6, 24 and 48 hours after transplantation. Using an Alzet implantable osmotic pump, subcutaneous administration of treprostinil (100 ng/kg/min) or placebo is performed. This dosage is chosen to produce a plasma concentration that is steady-state and falls between 5 and 20 ng/mL[3].
Mice: Mice that have had bone marrow transplantation (BMT) are split up into five groups, each with six to ten mice. In a normobaric chamber, one group of mice is exposed to hypoxia (10% inspired oxygen fraction), while the other group of mice (control BMT) spends 28 days in a normoxic chamber with a normal oxygen environment (21% inspired O2 fraction). While the two other groups of mice receive four weeks of hypoxic exposure and receive Treprostinil infusions at varying dose levels (14 ng/kg and 70 ng/kg per minute), the sham group mice receive saline treatment. Comparatively, infusion rates for humans in PAH therapy range from 10 to 60 ng/kg per minute[6]. |

1、根据实验需要选择合适的溶剂配制储备液 (母液):对于大多数产品,InvivoChem推荐用DMSO配置母液 (比如:5、10、20mM或者10、20、50 mg/mL浓度),个别水溶性高的产品可直接溶于水。产品在DMSO 、水或其他溶剂中的具体溶解度详见上”溶解度 (体外)”部分;
2、如果您找不到您想要的溶解度信息,或者很难将产品溶解在溶液中,请联系我们;
3、建议使用下列计算器进行相关计算(摩尔浓度计算器、稀释计算器、分子量计算器、重组计算器等);
4、母液配好之后,将其分装到常规用量,并储存在-20°C或-80°C,尽量减少反复冻融循环。
计算结果:
工作液浓度: mg/mL;
DMSO母液配制方法: mg 药物溶于 μL DMSO溶液(母液浓度 mg/mL)。如该浓度超过该批次药物DMSO溶解度,请首先与我们联系。
体内配方配制方法:取 μL DMSO母液,加入 μL PEG300,混匀澄清后加入μL Tween 80,混匀澄清后加入 μL ddH2O,混匀澄清。
(1) 请确保溶液澄清之后,再加入下一种溶剂 (助溶剂) 。可利用涡旋、超声或水浴加热等方法助溶;
(2) 一定要按顺序加入溶剂 (助溶剂) 。
