result was sub‐micromolar activity against cultured erythrocytic‐stageparasites of hybrid molecules containing one or two 8‐aminoquinoline moieties. These compounds were not clearly toxic to human cells. The most effective blood‐schizontocidal s‐triazine derivatives were then screened for activity against the liverstage of malariaparasites. The s‐triazine hybrid containing two 8‐aminoquinoline moieties
筛选了基于s-三嗪的杂种的面向多样性的文库,以研究其对氯喹抗性恶性疟原虫W2菌株的活性。最惊人的结果是对含有一个或两个8-氨基喹啉部分的杂合分子的培养的红细胞阶段寄生虫具有亚微摩尔活性。这些化合物对人体细胞没有明显的毒性。然后筛选出最有效的血液杀schizontosdal s -triazine衍生物对抗疟原虫肝阶段的活性。所述š含有两个8-氨基喹啉结构部分和一个氯原子成为最有力的抵抗嗪混合伯氏疟原虫肝阶段感染,在低纳摩尔区域活跃,并在大鼠肝微粒体中具有良好的代谢稳定性。这些结果表明,基于s-三嗪-8-氨基喹啉的杂种作为双阶段抗疟药是铅优化的极佳起点。

Several specific synthetic protocols were developed for the preparation from cyanuric chloride of a range of symmetric and non-symmetric di- and tri-substituted 1,3,5-triazines containing alkyl, aromatic, hindered, chiral and achiral hydroxyalkyl, ester and imidazole groups via sequential nucleophilic substitution of the C-Cl bond by C-O, C-N and C-S bonds.
