Macrosphelide L has been isolated from a strain of Periconia byssoides originally separated from the sea hare Aplysia kurodai, and the absolute stereostructures of this material and macrosphelide H, previously undetermined, have been elucidated on the basis of spectroscopic analyses using 1D and 2D NMR techniques and some chemical transformation. (R)-Methyl 3-p-bromobenzoyloxy-5-oxohexanoate has been synthesized for configurational assignments of macrosphelide H. These macrosphelides inhibited the adhesion of human-leukemia HL-60 cells to HUVEC.
宏蛛苷L是从一种原本分离自海兔Aplysia kurodai的Periconia byssoides菌株中分离得到的,材料的绝对立体结构以及此前未确定的宏蛛苷H的立体结构已通过1D和2D NMR技术以及一些化学转化的光谱分析得到阐明。为了确定宏蛛苷H的构型,合成了(R)-甲基3-p-溴苯酰氧基-5-氧基己酸酯。这些宏蛛苷抑制了人类白血病HL-60细胞与人脐静脉内皮细胞(HUVEC)的粘附。
