Primary TargetβARK1 (β-Adrenergic Receptor Kinase 1)

General description

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.

A selective inhibitor of βARK1 (β-Adrenergic Receptor Kinase 1) (IC₅₀ = 126 µM). Has no inhibitory activity against protein kinase A (PKA).
