Sodium taurocholate 是一种具有显著生物活性的化合物，可通过上调VEGF-A的表达抑制肝动脉结扎所致的胆道损伤，同时具有一定的免疫调节作用，可用于诱导胰腺炎模型。

Taurocholic acid（N-Choloyltaurine）是一种参与脂肪乳化的胆汁酸，具有显著的生物活性和免疫调节作用，可通过上调VEGF-A表达抑制肝动脉结扎诱导的胆道损伤，并通过PI3K介导的途径防止肿瘤坏死因子-α诱导的胆管细胞损伤，常用于诱导胰腺炎模型。

(±)14(15)-EET is a metabolite of arachidonic acid that is formed via epoxidation of arachidonic acid by cytochrome P450.[1],[2] It prevents increases in leukotriene B4, ICAM-1, and chemokine (C-C motif) ligand 1 (CCL2) induced by oxidized LDL in primary rat pulmonary artery endothelial cells (RPAECs) when used at a concentration of 1 μM.[3] (±)14(15)-EET induces dilation of preconstricted isolated canine coronary arterioles (EC50 = 0.2 pM).[4] It reduces myocardial infarct size as a percentage of the area at risk in a canine model of ischemia-reperfusion injury induced by left anterior descending coronary artery (LAD) occlusion when administered at a dose of 0.128 mg kg prior to occlusion or reperfusion.[5] Reference：[1].

Tat-Gap 19是一种针对连接蛋白43 (Cx43) 半通道的肽抑制剂，由HIV-1 Tat蛋白传导域与对应于Cx43第128-136残基的九氨基酸肽连接而成。Tat-Gap 19 (10 µM) 能够抑制初级大鼠肝细胞中由谷氨酸引发的ATP释放，这是Cx43半通道活性的标志。在通过中脑动脉堵塞(MCAO)诱导的小鼠脑缺血再灌注损伤模型中，以25 mg/kg的剂量进行给药，可减少梗死体积。腹腔内注射Tat-Gap 19 (1 mg/kg 每天) 能够减少硫代乙酰胺引起的小鼠肝损伤模型中的纤维化病灶面积及表达α-平滑肌肌动蛋白 (α-SMA) 的肝星状细胞（成纤维细胞的前体）面积，并提高同种小鼠分离的肝细胞中超氧化物歧化酶 (SOD) 活性。
