What is 20-CARBOXY-LEUKOTRIENE B4?

Description

20-carboxy LTB₄ is a metabolite of LTB₄ in human neutrophils. In human leukocytes, LTB₄ is inactivated by the enzyme LTB₄ 20-hydroxylase. The resulting 20-hydroxy LTB₄ is further oxidized to 20-carboxy LTB₄. LTB₄ metabolism in isolated rat hepatocytes also results in production of 20-carboxy LTB₄ along with other ω-oxidation products. The biological activity of 20-carboxy LTB₄ is only about 2.6% compared to that of LTB₄ in causing PMNL degranulation.

The Uses of 20-CARBOXY-LEUKOTRIENE B4
