Palustric Acid

Palustric acid is a diterpenoid that has been found in P. resinosa and has diverse biological activities. It increases secreted hydrogen peroxide levels in isolated mouse macrophages when used at a concentration of 2 mg/ml. Palustric acid is toxic to water fleas (D. magna) and rainbow trout (S. gairdneri, LC50s = 0.1 and 0.5 mg/L, respectively). Phloem levels of palustric acid are increased in mechanically injured, as well as mechanically injured and L. abietinum-infected, red pine and white spruce trees. It has been found as an environmental contaminant in pulp and paper mill effluent.Formal Name: (1R,4aS,10aR)-1,2,3,4,4a,5,6,9,10,10a-decahydro-1,4a-dimethyl-7-(1-methylethyl)-1-phenanthrenecarboxylic acid.
