A new furanone derivative, butanolide A (1), and a new sesquiterpene, guignarderemophilane F (2), together with six known compounds, were isolated from the fungus Penicillium sp. S-1-18 derived from Antarctic marine. The new structures were determined by spectroscopic studies such as 1D- and 2D-NMR and MS analyses. The absolute configuration of 1 was determined by the modified Mosher's method, while the absolute configuration of 2 was determined by calculated ECD spectroscopy. The isolated secondary metabolites were evaluated for their protein tyrosine phosphatase 1B (PTP1B) inhibitory activity. Compound 1 showed moderate inhibitory activity against PTP1B with IC value of 27.4 μM.
从源自南极海洋的青霉菌 Penicillium sp. S-1-18 中分离出一种新的呋喃酮衍生物丁醇内酯 A（1）、一种新的倍半萜吉纳德瑞莫菲兰 F（2）以及六种已知化合物。通过 1D 和 2D-NMR 以及 MS 分析等光谱研究确定了新结构。1 的绝对构型通过改良的莫舍尔方法确定，而 2 的绝对构型通过计算电子圆二色光谱确定。对分离得到的次生代谢产物进行了蛋白酪氨酸磷酸酶 1B（PTP1B）抑制活性评估。化合物 1 对 PTP1B 表现出中等抑制活性，IC 值为 27.4 μM。
