A selective inhibitor of β-adrenergic receptor kinase 1 (βARK1) (IC₅₀ = 126 µM). Displays no inhibitory activity against protein kinase A (PKA). Identified from a group of existing compounds (not previously demonstrated to inhibit βARK1) using a two-step rational drug design protocol that included molecular modeling and comparative docking studies. Represents the first inhibitor that distinguishes between βARK1 and PKA, an enzyme with a similar adenine binding pocket. May be useful in the study of mechanisms involved in congestive heart failure where elevated levels of βARK1 desensitize agonist-bound β2-adrenergic receptors.，官网链接：https://www.sigmaaldrich.cn/product/mm/182200 默克 科研、开发、生产。 作为生命科学行业的全球领先供应商，我们致力于为科研、生物技术开发和生产，以及制药药物疗法开发和生产提供各类解决方案和服务。
