Theophylline derivatives have long been recognized as potent bronchodilators for the relief of acute asthma. Recently, it was found that bacterial infection has a role in asthma pathogenesis. The present work involves the design and synthesis of 8-substituted theophylline derivatives as bronchodilators and antibacterial agents. The chemical structures of these compounds were elucidated by IR, 1H-NMR
长期以来,茶碱衍生物被认为是缓解急性哮喘的有效支气管扩张剂。最近,发现细菌感染在哮喘发病机制中起作用。目前的工作涉及作为支气管扩张剂和抗菌剂的 8-取代茶碱衍生物的设计和合成。这些化合物的化学结构通过IR、1H-NMR、质谱和元素分析阐明。使用乙酰胆碱诱导的豚鼠支气管痉挛评估支气管扩张剂活性,与标准氨茶碱相比,大多数化合物显示出显着的抗支气管收缩活性。此外,使用氨苄青霉素作为参考药物,在体外研究了所有目标化合物对革兰氏阳性菌和革兰氏阴性菌的抗菌活性。结果表明,一些测试化合物具有显着的抗菌活性。计算药效团模型以获得对支气管扩张剂活性的基本结构特征的有用洞察。还讨论了构效关系。
