阿拉瑞林可通过直接作用于大鼠壁细胞和抑制迷走神经功能来抑制胃酸分泌[2]。阿拉瑞林可显着提高大鼠 GSMC G1 期比例、降低 S 期比例[1]。

将细胞在 2.5 g/L 胰蛋白酶溶液中进行胰蛋白酶处理后接种到 96 孔板中。经过 24 小时的生长期，达到约 800 g/L 的亚汇合状态后，每孔补充 0.1 mL 含有 2.5% 小牛血清和不同浓度（0.001、0.1 和 10 μM）阿拉瑞林的培养基。然后将孔在 CO2 培养箱中培养一整天。至少使用十二个孔来测试每个浓度。总之，每孔加入 15 μL MTT 溶液，然后孵育 4 小时。取出培养基和 MTT 后，每孔加入 150 μL DMSO，加入并摇动 10 分钟以溶解晶体。 ELISA 读数器用于测量 490 nm 处的 OD [1]。

| 动物实验 |
Rats: There are two groups of male Sprague-Dawley rats. Group I: A chambered stomach is used to measure the amount of gastric acid secreted. In short, the abdomen is cut, the stomach and duodemun are exposed and tied, respectively, and 1.5 mL of 0.9% sodium chloride (containing 2 μg/kg of Alarelin) is infused into each of the stomach's chambers. The pH is measured in the ABL-500 after 15, 30, 45, and 60 minutes, respectively, and the gastric juice is extracted from the chambered stomach. Saline is infused in place of alarelin as the control. Group II: Following anesthesia, 2 mL of Alarelin (2 μg/kg) is injected into the vein of the tail. Saline is injected as the control rather than alarelin. After that, the duodenum and stomach are tied off and given an instant 1.5 mL saline infusion.

Solubility in Formulation 1: ≥ 2.08 mg/mL (1.62 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 20.8 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 2.08 mg/mL (1.62 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 20.8 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C，1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. View More

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) 。
