Abstract
Effects of biscoclaurine alkaloids on the various stimulus-responses of PMN, especially on the O2-. generation of PMN, were investigated. Results obtained were: cepharanthine inhibited various metabolic responses of PMN, its biological action probably being due to its membrane modifying action. Inhibition of O2-. generation by cepharanthine was stronger than any other inhibition of metabolic responses of PMN. The inhibitory effect of various biscoclaurine alkaloids on the O2-. generation of PMN was the descending order of tri-, di- and mono-ether type; the coclaurine type showed only a weak effect.
