Alterbrassinoids A-D (-), the first examples of fusicoccane-derived diterpenoid dimers furnished by forming an undescribed C-12-C-18' linkage, were isolated from modified cultures of . Compounds and represent unprecedented heterodimers, whereas and represent unprecedented homodimers, and also features an undescribed anhydride motif. Their structures were assigned via spectroscopic methods, electronic circular dichroism calculations, and single-crystal X-ray diffraction. Putative biosynthetic pathways and a bioactivity evaluation for - were discussed.
