Three new thiodiketopiperazines, geospallins A⁻C (⁻), together with nine known analogues (⁻), were isolated from the culture of the deep-sea sediment-derived fungus FS140. Among them, geospallins A and B ( and ) represent rare examples of thiodiketopiperazines featuring an S-methyl group at C-10 and a tertiary hydroxyl group at C-11. Their structures were determined by high-resolution electrospray mass spectrometry (HRESIMS), spectroscopic analyses, and electronic circular dichroism (ECD) calculations. Their angiotensin-converting enzyme (ACE) inhibitory activity was reported, and geospallins A⁻C (⁻) showed inhibitory activity with IC values of 29⁻35 µM.
从深海沉积物来源的真菌 FS140 的培养物中分离得到三个新的硫代二酮哌嗪化合物，即 geospallins A⁻C（⁻），以及九个已知类似物（⁻）。其中，geospallins A 和 B（ 和 ）代表了具有 C-10 位 S-甲基和 C-11 位叔羟基的硫代二酮哌嗪的罕见实例。它们的结构通过高分辨电喷雾质谱（HRESIMS）、光谱分析和电子圆二色性（ECD）计算确定。报道了它们的血管紧张素转化酶（ACE）抑制活性，geospallins A⁻C（⁻）表现出抑制活性，IC 值为 29⁻35 µM。
