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.

项目摘要： 该研究建议的目的是了解阻止苦味的分子基础 艾滋病毒/艾滋病药物，以便可以消除它们通常令人不愉快的苦味味道。有些药物有 浓烈的苦味，这使患者服用它们是一项具有挑战性的任务，尤其是 婴儿和幼儿。因为许多孩子无法吞下药丸，所以小儿药 通常以液体或糖浆形式出现，经常味道苦，很难掩盖， 即使在调味液配方中。据报道，当孩子们拒绝接受 苦味的艾滋病毒/艾滋病药物，并且没有适当的药物剂量，他们可以发展 对药物的抵抗力，对其健康造成了严重影响。因此，有一个 需要开发苦味的味道阻滞剂，以掩盖艾滋病毒/艾滋病药物的不愉快味道。 了解苦味药物诱导的Tas2r受体激活的机制可能是 导致发现苦味阻滞剂，可以用来掩盖不愉快的口味 艾滋病毒/艾滋病药物。在此提案中，我们开发了可检验的HIV/AIDS药物模型 通过计算方法的Tas2R受体，我们的计划是通过实验测试它们。 此外，使用基于结构的药物设计和有机合成，我们旨在发现新颖的 人类TAS2R特异性阻滞剂掩盖了不同艾滋病毒/艾滋病药物的不愉快的苦味。
