The first chemical study of the Indo-Pacific dorid nudibranch Aldisa andersoni resulted in the isolation of five chlorinated phenyl-pyrrolyloxazoles belonging to the phorbazole series. Two new molecules, 9-chloro-phorbazole D and N1-methyl-phorbazole A, co-occurring with known phorbazoles A, B and D, have been characterized. Phorbazoles were found to be present mainly in the external part of the mollusc. The structures of the new compounds were determined by interpretation of spectroscopic data, mainly NMR and mass spectrometry and by comparison with the literature data. Evaluation of feeding-deterrence activity as well as in vitro growth inhibitory properties in human cancer cells was also carried out.
通过对印度-太平洋多鳃裸鳃亚纲 Aldisa andersoni 进行首次化学研究,分离出属于酞咔唑系列的五种氯化苯基吡咯并唑。 两种新分子,即 9-氯-酞咔唑 D 和 N1-甲基-酞咔唑 A,与已知的酞咔唑 A、B 和 D 共同存在,其特征已经确定。 研究发现,磷苯唑主要存在于软体动物的外部。 通过对光谱数据(主要是核磁共振和质谱)的解释以及与文献数据的比较,确定了新化合物的结构。 此外,还对人类癌细胞的摄食阻遏活性和体外生长抑制特性进行了评估。
