Three new caffeic acid esters (1−3), four new lignans (4−7), and the known compounds (7′S)-parabenzlactone (8), dihydrocubebin (9), and justiflorinol (10) have been isolated from leaves of Piper sanguineispicum. Their structures were determined by spectroscopic methods, including 1D and 2D NMR, HRCIMS, CD experiments, and chemical methods. Compounds 1−10 were assessed for their antileishmanial potential
三个新的咖啡酸的酯(1 - 3),四个新木脂素(4 - 7)和已知化合物(7'小号)-parabenzlactone(8),dihydrocubebin(9),和justiflorinol(10)已经从叶中分离的派珀sanguineispicum。它们的结构通过光谱方法确定,包括1D和2D NMR,HRCIMS,CD实验和化学方法。化合物1 - 10评估其针对的无菌无鞭毛体形式antileishmanial潜在的利什曼原虫亚马孙。咖啡酸酯1和3在鼠巨噬细胞上表现出最佳的抗真菌活性(分别为IC 50 2.0和1.8μM),且具有中等的细胞毒性。
