leukotriene b-5

Leukotriene B5 (LTB5) is a leukotriene with diverse biological activities. It is a metabolite of eicosapentaenoic acid formed through the 5-lipoxygenase (5-LO) pathway. LTB5 increases contraction of bullfrog lung strips ex vivo in a concentration-dependent manner. In vivo, LTB5 (100 nM) reduces tumor volume in mice injected with Tm1 murine melanoma cells. LTB5 also elicits chemokinesis and lysosomal enzyme release from polymorphonuclear leukocytes (PMNLs) 20- to 30-fold less, and induces platelet aggregation 8-fold less, potently than LTB4 .

Leukotriene B4 (LTB4) 是一种通过 5-脂氧合酶途径从花生四烯酸衍生而来的化合物，可介导某些炎症和免疫反应。Leukotriene B4 诱导中性粒细胞胞外陷阱阻碍肺孢子菌的清除。

11-Keto-beta-boswellic acid 是来自乳香的一种五环三萜酸，具有抗炎活性和剂量依赖性心脏保护作用，主要是由于抑制5-脂氧合酶、白三烯、NF-κB 的激活和肿瘤坏死因子 α 的产生。

Hinokiol exhibits anti-inflammatory activity by significantly inhibiting 5-hydroxy-eicosa-tetra-enoic acid (5-HETE) and leukotriene B(4) (LTB4) formations. Additionally, it demonstrates potent activity against clinical isolates of methicillin-resistant Staphylococcus aureus (MRSA).
