---

Section 7 - HANDLING and STORAGE
Handling:
Wash thoroughly after handling. Use with adequate ventilation. Avoid contact with eyes, skin, and clothing. Keep container tightly closed.
Avoid ingestion and inhalation.
Storage:
Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances.

  摘要：

  合成了一系列6-（二甲基氨基）-2-（三氟甲基）-9-（取代的苄基）嘌呤，并测试了其抗鼻病毒的活性。大多数化合物是通过6-氯-2-（三氟甲基）-9H-嘌呤与适当的苄基卤化物烷基化，然后用二甲胺取代氯基而合成的。或者，用适当的苄基卤将6-（二甲基氨基）-2-（三氟甲基）嘌呤烷基化。尽管几种不同的芳基取代基提供了针对鼻病毒1B血清型的IC50 = 0.03 microM的化合物，但同系物没有比母体2活性高得多。测试了23种化合物针对其他18种血清型的化合物，但均未显示出均匀的活性分布。
