Five New Maleic and Succinic Acid Derivatives from the Mycelium of<i>Antrodia</i><i>c</i><i>amphorata</i>and Their Cytotoxic Effects on LLC Tumor Cell Line

Abstract

Five new maleic and succinic acid derivatives were isolated from the mycelium of Antrodia camphorata. Their structures were determined by various spectroscopic means. Maleimide derivatives 2 and 3 showed appreciable cytotoxic activity against LLC cells.
