chaetoglobosin a

Chaetoglobosin A, the active compound extracted of Penicillium aquamarinium, is a member of the cytochalasan family. It preferentially induces apoptosis.

Chaetoglobosin E 是一种诱导铁死亡 (Ferroptosis) 的化合物，对人类肿瘤细胞系 MDA-MB231 和 A549 展示出显著的细胞毒性，其 IC50 分别为 9.14 μM 和 7.47 μM。Chaetoglobosin E 通过下调 A549 细胞中的 GPX4 表达，显著增加细胞内 Fe2+ 和脂质过氧化产物丙二醛 (MDA) 的水平，导致线粒体皱缩以及嵴减少或消失进而引发铁死亡。Chaetoglobosin E 可应用于癌症研究领域。

chaetoglobosin Vb 是一种从内生球藻中分离出来的新型细胞松弛素生物碱。

Chaetoglobosin C (Compound 4)，源自真菌Chaetomium globosum KMITL-N0802，为一种蒽醌-色酮类化合物，具备抗结核分枝杆菌的活性。
