✦ Synopsis

A radioimmunoassay for a new anticancer drug, bruceantin, has been developed using [3H]acetylbruceantin and antibody induced by immunizing rabbits with succinylbruceantinbovine serum albumin conjugates. [3H]Acetylbruceantin was synthesized by reacting bruceantin with [3H]acetyl anhydride. The assay is simple and reproducible. The standard curve was linear on a logit-log plot, and the lower limit of sensitivity of the assay was 1 rig/ml. Using this assay, drug levels were easily determined in tissues of experimental animals following bruceantin administration. The assay procedure does not require sample extraction for plasma, urine, and bile. Bruceantin in other tissues can be extracted quantitatively with ethanol before being measured by the radioimmunoassay.
