title: Endotoxic activity of complexes of myristic acid and proteins.
abstract: Complexes of myristic acid and bovine serum albumin, myristic acid and concanavalin A, beta-hydroxymyristic acid and concanavalin A, or dimethyl myristamide and concanavalin A are lethal for male BALB/c mice treated with mithramycin. Prior treatment of mice with myristic acid-protein complexes renders the animals resistant to a dose of bacterial endotoxin that is lethal for untreated animals. Prior treatment of mice with bacterial endotoxin renders them resistant to a combination of mithramycin and a complex of myristic acid and bovine serum albumin or dimethyl myristamide and concanvalin A that is lethal for untreated animals. These data indicate that a fatty acid is an important functional component of the endotoxin toxophore.
