Upper rim phosphonic acid functionalized calix[4]arene affects selective transport of multiple molecular payloads through a liquid membrane. The secret is in the attachment of a receptor-complementary handle to the payload. We find that the trimethylammonium ethylene group present in choline is one of several general handles for the transport of drug and drug-like species. Herein we compare the effect
上缘膦酸官能化的杯[4]芳烃影响多个分子有效负载通过液膜的选择性运输。秘密在于将受体互补手柄连接到有效负载上。我们发现胆碱中存在的三甲基铵亚乙基是药物和类药物物质运输的几个通用手柄之一。在这里,我们比较了手柄变化对血清素和多巴胺运输的影响。我们发现几个可电离的胺末端手柄足以进行运输并确定了两个理想的候选者。它们的性能在 HEPES 缓冲解决方案中得到显着增强。本次调查完成了一系列旨在优化该策略的 3 项研究。最终,出现了一种合成受体介导的选择性小分子转运的新方法;未来在囊泡和细胞系统方面的工作将随之而来。
