Four samples of Suberea ianthelliformis were investigated and furnished five new and 13 known brominated tyrosine-derived compounds. Two of the new compounds were identified as araplysillin N20-formamide and its N-oxide derivative. Three other new compounds, araplysillins IV, V, and VI, were isolated and identified as analogs of araplysillin II. Most of these compounds exhibit moderate inhibitory activities
调查了四个拟南芥(Suberea ianthelliformis)样品,并提供了五种新的和13种已知的溴化酪氨酸衍生化合物。两种新化合物被鉴定为rapysillin N20-甲酰胺及其N-氧化物衍生物。分离出了另外三种新化合物,即rapysillins IV,V和VI,并鉴定为rapysillin II的类似物。这些化合物中的大多数对恶性疟原虫的抗氯喹和敏感菌株表现出中等的抑制活性,并对其PFTase抑制特性进行了研究。被研究的海绵的化学含量与其分子系统发育相关。
