Molecular mechanism of the bitter taste of HIV/AIDS drugs and its inhibition

项目总结： 这项研究计划的目标是了解阻断苦味的分子基础 艾滋病毒/艾滋病药物，以便消除其通常令人不快的苦味。有些药物有一种 强烈的苦味，这使得患者服用它们是一个具有挑战性的任务，特别是对 婴幼儿。因为许多儿童不能吞下药片，儿科药物 通常以液体或糖浆的形式出现，它们经常尝起来很苦，很难掩盖， 即使在调味液体配方中也是如此。据报道，当孩子们拒绝服用 苦味的艾滋病毒/艾滋病药物，如果得不到适当剂量的药物，它们就会发展 对药物的抗药性，这对他们的健康造成了严重的后果。因此，有一个 需要开发苦味阻滞剂来掩盖艾滋病毒/艾滋病药物令人不快的味道。 了解苦味药物诱导TAS2R受体激活的机制是可能的 导致发现苦味阻滞剂，它可以用来掩盖不愉快的味道 艾滋病毒/艾滋病药物。在这项提案中，我们开发了艾滋病毒/艾滋病药物的可测试模型- TAS2R受体的计算方法，我们的计划是对它们进行实验测试。 此外，利用基于结构的药物设计和有机合成，我们的目标是发现新的 人类TAS2R特异性阻滞剂，以掩盖不同艾滋病毒/艾滋病药物令人不快的苦味。

Project Summary: The goal of this research proposal is to understand the molecular basis of blocking bitter taste for HIV/AIDS drugs so that their often unpleasant bitter taste can be eliminated. Some drugs have a strong bitter taste, which makes it a challenging task for patients to take them, especially for infants and young children. Because many children cannot swallow pills, pediatric medicines usually come in liquid or syrup form, which frequently taste bitter and is very difficult to mask, even in flavored liquid formulations. It has been reported that when children refuse to take the bitter-tasting HIV/AIDS drugs, and do not get the proper dosage of their drugs, they can develop resistance to the drugs, which has serious consequences for their health. Therefore, there is a need to develop bitter taste blockers to mask the unpleasant taste of HIV/AIDS drugs. Understanding the mechanism of bitter-tasting drug-induced TAS2R receptor activation is likely to lead to discovering bitter taste blockers, which could be used to mask the unpleasant taste of HIV/AIDS drugs. In this proposal, we have developed testable models of the HIV/AIDS drug- TAS2R receptors by computational approaches and our plan is to test them experimentally. Moreover, using structure-based drug design and organic synthesis we aim to discover novel human TAS2R specific blockers to mask the unpleasant bitter taste of different HIV/AIDS drugs.
