Discovery of (2S,4R)-1-(2-Aminoacetyl)-4-benzamidopyrrolidine-2-carboxylic Acid Hydrochloride (GAP-134)13, an Orally Active Small Molecule Gap-Junction Modifier for the Treatment of Atrial Fibrillation
摘要:
Rotigaptide (3) is an antiarrhythmic peptide that improve cardiac conduction by modifying gap-junction communication. Small molecule gap-junction modifiers with improved physical properties were identified from a Zealand Pharma peptide library using pharmaceutical profiling, established SAR around 3, and a putative pharmacophore model for rotigaptide. Activity of the compounds was confirmed in a mouse cardiac conduction block model of arrhythmia. Dipeptide 9f (GAP-134) was identified as a potent, orally active gap-junction modifer for clinical development.
Lysine mimetic compounds having useful pharmacological activity such as antiarrhythmic activity and desirable bioavailability properties are disclosed.
Lysine mimetic compounds having useful pharmacological activity such as antiarrhythmic activity and desirable bioavailability properties are disclosed.
Provided are methods for the preparation of certain substituted pyrrolidine compounds, forms of (2S,4R)-1-(2-aminoacetyl)-4-benzamidopyrrolidine-2-carboxylic acid hydrochloride, and methods for preparing and using these forms.
