Chemical examination of the bright yellow sponge Leucetta chagosensis resulted in the isolation of three new imidazole‐based alkaloid complexes namely chagosendines A – C (1 – 3), together with known analogues pyronaamidine, naamidine J, and naamine C. Their structures were determined on the basis of extensive spectroscopic (IR, MS, NMR, and single‐crystal X‐ray diffraction) analysis in association
亮黄色海绵 Leucetta chagosensis 的化学检查导致分离出三种新的咪唑类生物碱复合物,即 chagosendines A – C (1 – 3),以及已知的类似物吡喃脒、萘脒 J 和萘胺 C。它们的结构是在广泛的光谱(IR、MS、NMR 和单晶 X 射线衍射)分析与化学转化相关的基础。评估了分离的生物碱和三个合成的新同型二聚体复合物对一组肿瘤细胞系的细胞毒性活性。首次从自然界中发现的咪唑生物碱 2 和 3 的铜配合物对肿瘤细胞系 K562、HepG2 和 HeLa 具有选择性和显着的活性。
