One new racemic mixture, penicilliode A (1) and four pairs of enantiomeric polyketides, penicilliode B and C (2 and 3) and coniochaetone B and C (4 and 5), were obtained from the starfish-derived symbiotic fungus Penicillium sp. GGF16-1-2. Interestingly, the strain GGF16-1-2 can produce enantiomers. The absolute configuration of 1 was determined by X-ray diffraction (XRD) analysis, and the absolute
从海星衍生的共生真菌青霉菌(Penicillium sp。)中获得了一种新的外消旋混合物,青霉菌A(1)和四对对映体聚酮化合物,青霉菌B和C(2和3)以及对苯二甲酮B和C(4和5)。GGF16-1-2。有趣的是,菌株GGF16-1-2可产生对映体。通过X射线衍射(XRD)分析确定1的绝对构型,通过旋光度(OR)值和电子圆二色性(ECD)计算确定2-4的绝对构型。首先从海洋真菌青霉属中分离出化合物1-5为外消旋物,并通过HPLC与手性固定相分离化合物2-5。评价所有化合物对PDE4D2的抗菌,细胞毒性和抑制活性。
