Product Introduction
Bioactivity
| 名称 | LY255283 |
| 描述 | LY255283 is a specific antagonit of leukotriene B4 (LTB4) receptor. It inhibits the production of LTB(4) in human peripheral blood polymorphonuclear leukocytes (PMNL) and in monocytes activated by calcium ionophore A23187. |
| 体内活性 | All seven rats given only the vehicle died within 2 h of reperfusion, whereas rats treated with LY-255283 (3 or 10 mg/kg iv), a leukotriene B4 (LTB4) receptor antagonist given 10 min before reperfusion, exhibited significantly higher survival rates of 57% (4 out of 7) and 75% (6 out of 8), respectively, 2 h after reperfusion.?Rats given 1 mg/kg of LY-255283 showed no significant improvement in survival.?Splanchnic artery occlusion (SAO)-shock rats treated with LY-255283 (3 or 10 mg/kg) exhibited significantly attenuated accumulation of plasma free amino-nitrogenous compounds and of a myocardial depressant factor.?Treatment with LY-255283 (10 mg/kg) markedly (P less than 0.01) ameliorated the deficits of endothelium-dependent relaxation of isolated superior mesenteric artery (SMA) rings in untreated SAO-shock rats.?LY-255283 at 10 mg/kg significantly attenuated the increased myeloperoxidase activity in the intestinal tissue of SAO-shock rats[1]. |
| 存储条件 | Powder: -20°C for 3 years | In solvent: -80°C for 1 year Shipping with blue ice/Shipping at ambient temperature. |
| 溶解度 | DMSO : 25 mg/mL (69.36 mM), Sonication is recommended. |

文献和实验使用它的拮抗剂或抑制剂去反复证明,LY就是其中之一,而这些保护药的拮抗剂或抑制剂当然是不会用于人身上的,要不然细胞实验和动物实验还有什么意义呢? shaaou tom88339 wrote: 很奇怪很多人总是用DMSO来作溶剂来做药理的实验。 不溶的化合物要用乳化剂、助悬剂或增溶剂来分散或溶解。乳化剂可用泊洛沙姆、助悬剂常用CMCNa,增溶剂可选用吐温80或CO40。
