辅酶 A (CoA) 生物合成酶已被用于生产各种 CoA 类似物,包括 CoA 依赖性酶的机械探针,例如参与脂肪酸生物合成的酶。这些酶对于激活泛酰胺类抗菌剂和最近报道的抗生素抗性抑制剂家族也很重要。在此我们报告了泛酸激酶选择性的研究,泛酸激酶是 CoA 生物合成的第一步和限速步骤。开发了一种强大的合成路线,以允许快速访问在 β-丙氨酸部分、羧酸盐或孪生二甲基基团上多样化的泛酸类似物的小型文库。所有衍生物均作为大肠杆菌泛酸激酶 ( Ec潘K)。四种衍生物,全是N-芳香族泛酰胺,被证明与作为Ec PanK底物的基准N-戊基泛酰胺 (N5-pan)等效,而另外两种也具有N-芳香族基团,是为此报道的一些最佳底物酶。这些数据为未来在生产有用的 CoA 类似物时设计 PanK 底物提供了见解。

development of bitopicligands aimed at targeting the orthosteric binding site (OBS) and a metastable binding site (MBS) within the same receptor unit. Previous molecular dynamics studies on ligand binding to the β2-adrenergic receptor (β2AR) suggested that ligands pause at transient, less-conserved MBSs. We envisioned that MBSs can be regarded as allosteric binding sites and targeted by homobivalent bitopic

This disclosure features chemical entities (e.g., a compound or a pharmaceutically acceptable salt and/or hydrate and/or prodrug of the compound) that modulate (e.g., agonize or partially agonize or antagonize) glucagon?like peptide?1 receptor ("GLP?1R") and/or the gastric inhibitory polypeptide receptor ("GIPR"). The chemical entities are useful, e.g., for treating a subject (e.g., a human) having a disease, disorder, or condition in which modulation (e.g., agonism, partial agonism or antagonism) of GLP?1R and/or GIPR activities is benficial for the treatment or prevention of the underlying pathology and/or symptoms and/or progression of the disease, disorder, or condition. In some embodiments, the modulation results in an enhancment of (e.g., an increase in) existing levels (e.g., normal or below normal levels) of GLP?1R and/or GIPR activity (e.g., signaling). In some embodiments, the chemical entities described herein further modulate (e.g., attenuate, uncouple) -arrestin signaling relative to what is observed with the native ligand. This disclosure also features compositions as well as other methods of using and making the said chemical entities.
