Two previously unreported citrinin dimer derivatives, penicitol D () and 1--citrinin H1 (), were isolated from the culture of a deep sea-derived fungus NLG-S01-P1, together with 11 biogenetic related compounds (⁻). A plausible biogenetic pathway for compounds ⁻ was proposed. Their structures, including absolute configurations, were established through analysis of extensive spectroscopic data and time-dependent density functional theory (TD-DFT) ECD calculations. Compounds and showed antibacterial activities against methicillin-resistant (MRSA). Compounds and displayed relatively stronger activities than the other compounds against and . Compound showed the most potent cytotoxic activity towards the HeLa cell.
从深海来源真菌 NLG-S01-P1 的培养物中分离得到两个以前未报道的桔青霉素二聚体衍生物，penicitol D () 和 1--桔青霉素 H1 ()，以及 11 个生物合成相关化合物 (⁻)。提出了化合物 ⁻ 的可能生物合成途径。通过分析广泛的光谱数据和时间依赖的密度泛函理论 (TD-DFT) ECD 计算，确定了它们的结构，包括绝对构型。化合物 和 对耐甲氧西林金黄色葡萄球菌 (MRSA) 具有抗菌活性。化合物 和 对 和 的活性均强于其他化合物。化合物 对 HeLa 细胞表现出最强的细胞毒性活性。
