✦ Synopsis


The cytotoxic marine alkaloid ascididemin has been shown to be a thiol-dependent DNA cleaving agent. Previous mechanisms of action studies have concluded that DNA and/or the DNA processing enzyme topoisomerase II were the cellular targets for the alkaloid -this is the first direct evidence that a pyridoacridone alkaloid can cause DNA cleavage under physiological conditions.
