Armochaeglobines A (1) and B (2), two indole-based cytochalasan alkaloids with new carbon skeletons, were obtained from the fungus Chaetomium globosum TW1-1, which was first isolated from the arthropod Armadillidium vulgare. Their structures were elucidated by extensive spectroscopic analyses, ECD calculation, and single-crystal X-ray diffraction analysis. Interestingly, compound 1 featured a unique tetracyclic 5/6/7/5 fused ring system and 2 possessed a rare 12-membered carbon scaffold.
