A series of secondary amines (4–19) containing 2-chloroquinoline as lipophilic domain have been synthesized based on the structural requirements essential for allylamine/benzylamine antimycotics by nucleophilic substitution reaction of 3-chloromethyl-2-chloroquinoline 3 with various aliphatic and aromatic amines in absolute ethanol in the presence of triethylamine. Some N-methyl derivatives (20–25)
一系列仲胺的(4 - 19)含有2-氯喹啉作为亲脂性结构域基于由3-氯-2-氯喹啉的亲核取代反应所必需的结构要求对烯丙胺/苄胺抗真菌剂已经合成了3与各种脂族和芳族胺在三乙胺存在下在无水乙醇中。还使用(CH 3)2 SO 4 / NaH通过N-甲基化合成了一些N-甲基衍生物(20 – 25)。结合使用IR,1 H-NMR建立新合成化合物的结构,13 C-NMR和质谱。化合物4 – 25在体外以浓稠度进行了筛选。通过特比萘芬作为参照药物通过杯板法测定了200 g / ml的抗黑曲霉MTCC 281,黄曲霉MTCC 277,紫曲霉MTCC 369和柠檬青霉NCIM 768的抗真菌活性。之间的仲胺,化合物4,5,8,10,14,和16显示出潜在的抗真菌活性,它们相应ñ -甲基(20 - 25)衍生物还显示出对真菌菌株黑曲霉MTCC 281,黄曲霉MTCC 277的抗真菌活性进一步提高。化合物3-氯-N
