Chemical investigation on the solid rice culture of Chaetomium globosum D38, an endophytic fungus derived from Salvia miltiorrhiza, has afforded two new 19,20-seco-chaetoglobosins, salchaetoglobosins A (1) and B (2), along with three known analogues, chaetoglobosins E (3), Fex (4), and V (5). Their structures and absolute configurations were elucidated by a set of spectroscopy and single-crystal X-ray crystallography. Compounds 1-5 were evaluated for their cytotoxic activities against HCT-116 (colorectal carcinoma) and PC3 (prostate cancer) cells, as well as the NO production inhibitory effects in LPS-stimulated RAW264.7 cells.
从丹参内生真菌Chaetomium globosum D38 的固体大米培养物中进行的化学研究，得到了两种新的 19,20-裂殖环二萜，即 salchaetoglobosins A（1）和 B（2），以及三种已知的类似物，chaetoglobosins E（3）、Fex（4）和 V（5）。通过一系列光谱和单晶 X 射线晶体学解析了它们的结构和绝对构型。评估了化合物 1-5 对 HCT-116（结直肠癌）和 PC3（前列腺癌）细胞的细胞毒性活性，以及对 LPS 刺激的 RAW264.7 细胞中 NO 产生的抑制作用。
