Trematosphones A (1) and B (2), two unique dimers with novel structural features, were isolated from the special bioenvironmental desert plant endophytic fungus Trematosphaeria terricola. Their structures were assigned on the basis of spectroscopic approaches including NMR, calculated electronic circular dichroism data, and X-ray diffraction analysis. Possible biosynthetic pathways of these two compounds were proposed. Trematosphone A (1) exhibited protective activities against the corticosterone-induced damages in PC12.
