用于心力衰竭的一类新型治疗药物,高效和选择性的GRK2抑制剂,在体外研究中表现出增强的β-肾上腺素信号传导能力。HTS将衍生物5和1,2,4-三唑衍生物24a鉴定为命中化合物。新一代的脚手架和所有部分的SAR研究都产生了带有N-苄基羧酰胺部分的4-甲基-1,2,4-三唑衍生物,对GRK2的活性很高,对其他激酶的选择性更高。在亚型选择性方面,这些化合物对GRK1、5、6和7表现出足够的选择性,并且对GRK3具有几乎相同的抑制作用。我们的药物化学努力导致发现了115h(GRK2 IC 50= 18 nM),获得了与人GRK2和GRK2抑制剂的共晶体结构,该抑制剂增强了β-肾上腺素能受体(βAR)介导的cAMP积累,并防止了用异丙肾上腺素处理过的表达β2AR的HEK293细胞中βAR的内在化。因此,115h似乎是心力衰竭治疗的一种新型疗法。

Direct oxidative amidation of aldehydes with amines catalyzed by heteropolyanion-based ionic liquids under solvent-free conditions via a dual-catalysis process
A simple and efficient procedure for the synthesis of amides directly from aldehydes and amines catalyzed by heteropolyanion-based ionic liquids undersolvent-freeconditions has been reported. The practical protocol was found to tolerate a wide range of substrates with different functional groups. Moderate to excellent yields, solvent-free media, and operational simplicity are the main highlights

Any synthetic transformation using contact-explosivesprimaryamines and hypervalent iodine(III) (phenyliodine diacetate) in constrained media (extreme conditions) is practically impossible. Herein, we report a method of controlling the explosion into a successfulchemicalreaction using the acid-salt NaHSO4. As a proof-of-concept, we considered mechanochemical (ball-milling) cross dehydrogenative
