Surinamensin, a neolignan isolated from Virola surinamensis, 3,4,5-trimethoxy-8-[2',6'-dimethoxy-4'-(E)-propenylphenoxy]-phenylpropane, a neolignan isolated from Virola pavonis, and 25 of its synthetic analogues or correlated substances with ether linkages and their corresponding C-8 sulphur and nitrogen analogues, were tested for activity against Leishmania donovani amastigotes and promastigotes in
Surinamensin,一种从 Virola surinamensis 中分离的新木脂素,3,4,5-trimethoxy-8-[2',6'-dimethoxy-4'-(E)-propenylphenoxy]-phenylpropane,一种从 Virola pavonis 中分离的新木脂素,以及 25在体外测试了其合成类似物或具有醚键的相关物质及其相应的 C-8 硫和氮类似物对多诺瓦利什曼原虫无鞭毛体和前鞭毛体的活性。有些在 30 microM 时对 L. donovani 前鞭毛体有活性,但对细胞内无鞭毛体无活性。来自 V.pavonis 的天然新木脂素对 100 microM 的前鞭毛体有活性。在具有硫桥的那些化合物中发现了最高的选择性活性。β-酮硫化物 (3,4-二甲氧基)-8-(4'-甲基噻吩氧基)-苯丙酮对 L. 产生了 42% 的抑制作用。
