Lithocaldehydes A (1) and B (2), a pair of novel diastereoisomers possessing an unprecedented 6/6/5/5/6 highly-fused ring system forming an earring-like skeleton, were isolated from the deep sea-derived fungus Phomopsis lithocarpus FS508. The structures of 1 and 2 were fully characterized and established through extensive spectroscopic interpretations and ECD calculations. Moreover, compounds 1 and 2 were shown to be promising antibiotics, exhibiting potent antifungal activities that are comparable to those of the positive control nystatin.
石炭醛 A（1）和 B（2）是一对新型非对映异构体，具有前所未有的 6/6/5/5/6 高度稠合环系，形成耳环状骨架，从深海来源的真菌 Phomopsis lithocarpus FS508 中分离得到。通过广泛的光谱解释和 ECD 计算，充分表征和确定了 1 和 2 的结构。此外，化合物 1 和 2 表现出有前景的抗生素活性，显示出与阳性对照制霉菌素相当的抗真菌活性。
