Abstract: This Letter describes the on-going SAR efforts based on ML297, a potent, efficacious and selective GIRK1/2 activator (∼ 10-fold vs GIRK1/4 and inactive on GIRK2/3) via an iterative parallel synthesis approach. The chemical optimization at the 3-position of pyrazole within ML297 indicated that various functionalized 3-cyclopropyl moieties modulated GIRK pharmacology between inhibitor/activator within a series of 1-(3-cyclopropyl-1-phenyl-1H-pyrazol-5-yl)ureas. Importantly, novel 'molecular switches' that modulated the mode of pharmacology from inhibitor to activator was discovered on both the 3-cyclopropyl and N-phenyl moiety of the pyrazole core, providing the first highly selective GIRK1/2 activator.
