Eight new diarylheptanoidglucosides 1-8 have been isolated from the leaves of Pyrostriamajor (A. Rich & DC.) Cavaco [syn. Canthium major (A. Rich & DC.)] Cavaco. Their structures were determined by 1D and 2D NMR spectroscopic and HRMS analyses. The absolute configurations of the diarylheptanoids 1-4 were determined to be 3S and 5S by the application of the CD exciton chirality method to the corresponding
从 Pyrostria major (A. Rich & DC.) Cavaco [syn. Canthium Major (A. Rich & DC.)] Cavaco。它们的结构由一维和二维核磁共振光谱和 HRMS 分析确定。通过将 CD 激子手性方法应用于相应的 3,5-双(对溴苯甲酰基)(1-3)和 3,5-双(对二甲氨基苯甲酰基) (4) 衍生物。报道了它们对恶性疟原虫、杜氏利什曼原虫(无鞭毛体形式)和布氏锥虫(锥体鞭毛体血流形式)的抗寄生虫活性以及对天然存在的二芳基庚烷类糖苷及其衍生物的 HL-60、KB 和 MRC5 细胞系的细胞毒活性.
