Five new phenolic compounds rynchopeterines A-E (-), in addition to thirteen known phenolics, were isolated from Fairmaire, a kind of medicinal insect utilized by the Yi Nationality in Yunnan Province of China. Their structures were established on the basis of extensive spectroscopic analyses (1D and 2D NMR, HR-MS, IR) along with calculated electronic circular dichroism method. Rynchopeterines A-E (-) exhibited significant antioxidant activities with IC values of 7.67-12.3 μg/mL measured by the 1,1-diphenyl-2-picrylhydrazyl (DPPH) assay. Besides, rynchopeterines B () and C () showed mild cytotoxicity against tumor cell Caco-2 and A549.
除了13种已知的酚类化合物外,还从中国云南省彝族使用的药用昆虫“蜚蠊”中分离出5种新的酚类化合物——隐翅虫素A - E(-)。它们的结构是基于广泛的光谱分析(一维和二维核磁共振、高分辨质谱、红外光谱)以及计算电子圆二色性方法确定的。通过1,1 - 二苯基 - 2 - 苦基肼(DPPH)法测定,隐翅虫素A - E(-)表现出显著的抗氧化活性,IC值为7.67 - 12.3μg/mL。此外,隐翅虫素B()和C()对肿瘤细胞Caco - 2和A549显示出轻微的细胞毒性。
