Summary: | [Display omitted]
•The novel GSK-3β inhibitor AF3581 has remarkable stabilizing properties on mood cycling, in animal models of mood disorders.•AF3581 prevented experimentally induced anhedonia in mice(down phase) and reduced the established aberrant hostile behavior towards intruder following long lasting isolation (up phase).•The efficacy of AF3581 in each animal model was always comparable to that of fully effective doses of reference drugs used.•In view of the promising pharmacological properties, AF3581 could be the prototype of a novel class of therapeutics for Bipolar Disorders.
Glycogen synthase kinase 3β (GSK-3β) is a serine/threonine protein kinase mediating phosphorylation on serine and threonine amino acid residues of several target molecules. The enzyme is involved in the regulation of many cellular processes and aberrant activity of GSK-3β has been linked to several disease conditions. There is now large evidence on the role of GSK-3β in the pathophysiology of mood disturbances with special regard to bipolar disorders. In the present study we further investigated the role of GSK-3β in bipolar disorders by studying AF3581, the prototype of a novel class of ATP-competitive GSK-3β inhibitors having the common N-[(1- alkylpiperidin-4-yl) methyl]-1H-indazole-3-carboxamide scaffold. Based on previous studies, AF3581 inhibits GSK-3β in the nanomolar range on purified human enzyme and highly selective with respect to other kinases. Current study demonstrates that the compound has efficacy both in the chronic mild stress paradigm of depression (mimicking the down phase of bipolar disorder) and on mice aggressiveness in the resident intruder model (mimicking the up phase). These findings underline the importance of aberrant GSK-3β activity in the development/ maintenance of mood oscillation in this peculiar pathological condition. Moreover, the present work also suggests a therapeutic potential for selective GSK-3 β inhibitors in the management of bipolar disorders patients.
