relationship that governs cooperativity in the assembly of complexmolecularrecognitioninterfaces. Specifically, variations in the chemical structures of the complexes have allowed us to change the supramolecular architecture, conformational flexibility, geometric complementarity, the number and nature of the H-bond interactions, and the overall stability of the complex. The free energy contributions
配备有外围 H 键功能的锌卟啉和吡啶配体家族的合成提供了获得各种密切相关的超分子复合物的途径,这些复合物具有 0 到 4 个分子内 H 键。自动紫外/可见滴定系统用于表征 120 种不同的复合物,这些数据用于构建大量不同的化学双突变循环,以量化分子内 H 键相互作用。结果探讨了在复杂分子识别界面组装中控制协同性的定量构效关系。具体来说,复合物化学结构的变化使我们能够改变超分子结构、构象灵活性、几何互补性、氢键相互作用的数量和性质,以及复合物的整体稳定性。来自单个氢键的自由能贡献是可加的,并且在形成分子内相互作用的有效摩尔浓度中,结构几乎没有变化。在几何上不可能的复合物中没有观察到分子内 H 键,但没有出现极好的几何互补性导致非常高的亲和力的情况。同样,构象灵活性的变化似乎对有效摩尔浓度 (EM) 的影响有限。使用双突变循环检查的所有 48 种分子内相互作用中发现的主要变化是,分子内羧酸酯-苯酚
Design, synthesis and biological evaluation of novel FFA1/GPR40 agonists: New breakthrough in an old scaffold
on an old phenoxyacetic acid scaffold, CPU014 (compound 14) has been identified as a superior agonist by comprehensive exploration of structure-activity relationship. In vitro toxicity study suggested that CPU014 has lower risk of hepatotoxicity than TAK-875. During acute toxicity study (5–500 mg/kg), a favorable therapeutic window of CPU014 was observed by evaluation of plasma profiles and liver slices

The rapidly prepared 1,3‐diaminobenzene‐derived aminophosphine pincer complex C6H3[NHP(piperidinyl)2]2Pd(Cl)} (1) is an effective Suzuki catalyst with excellentfunctionalgrouptolerance. Side‐product formations, such as homocoupling, debromation or protodeboration have only rarely been detected and if so, were in all cases below the 5% level. The presented reaction protocol is universally applicable
快速制备的1,3-二氨基苯衍生的氨基膦钳形配合物C 6 H 3 [NHP(哌啶基)2 ] 2 Pd(Cl)}(1)是一种有效的Suzuki催化剂,具有出色的官能团耐受性。仅很少检测到副产物形成,例如均偶联,去溴化或原去硼,如果这样,在所有情况下均低于5%的水平。提出的反应方案是普遍适用的。实验观察表明,钯纳米颗粒的催化活性形式1。
5-HT 7 receptor modulators: Amino groups attached to biphenyl scaffold determine functional activity
5-HT7 receptor (5-HT7R) agonists and antagonists have been reported to be used for treatment of neuropathic pain and depression, respectively. In this study, as a novel scaffold for 5-HT7R modulators, we designed and prepared a series of biphenyl-3-yl-methanamine derivatives with various amino groups. Evaluation of functional activities as well as binding affinities of the title compounds identified
