GtoPdb Ligand ID: 11292

Synonyms: AP-1189 | example 19 [WO2007141343A1]
Compound class: Synthetic organic
Comment: AP1189 is a biased agonist of melanocortin (MC) receptors. It was designed to elicit the proresolving properties of the MC1 and MC3 receptors in inflammation, whilst sparing their melanogenic effects [2]. This is achieved by bias towards ERK1/2 phosphorylation and and Ca2+ mobilisation rather than inducing canonical cAMP production. The chemical structure is claimed in Action Pharma's patent WO2007141343A1 (compound 2/example 19) [1].

SARS-CoV-2 and COVID-19: The proresolving activity of AP1189 is being investigated as a mechanism to combat the dysfunctional immune response in COVID-19 patients.
