Two amides, heitziamide A and heitziamide B and two phenylethanoids, heitziethanoid A and heitziethanoid B together with thirteen known compounds were isolated from F. heitzii (Letouzey). The structures of all compounds were established by spectroscopic analysis. Nine compounds were evaluated for oxidative burst inhibitory activity in a chemoluminescence assay and for cytotoxicity against PC-3 prostate
从 F. heitzii (Letouzey) 中分离出两种酰胺、heitziamide A 和 heitziamide B 以及两种苯乙醇类 heitziethanoid A 和 heitziethanoid B 以及 13 种已知化合物。所有化合物的结构均通过光谱分析确定。在化学发光测定中评估了九种化合物的氧化爆发抑制活性和对 PC-3 前列腺癌细胞的细胞毒性。所有化合物在激活与血清调理酵母聚糖在 IC(50)=2.0-6.5 microM 范围内对吞噬反应有明显的抑制作用,但没有观察到细胞毒性作用 (IC(50)>100 microM)。
