-
Paragraph 0391; 0392; 0393; 0394, (2016/08/07)
A compound exerts a strong analgesic effect against pain, in particular, neuropathic pain and/or fibromyalgia syndrome. The cyclic amine derivative is represented by formula, a prodrug thereof or a pharmacologically acceptable salt thereof: wherein A represents a group represented by Formula (IIa), (IIb) or (IIc): wherein R3 represents a hydrogen atom or an alkyl group having 1 to 6 carbon atoms, R4 represents a hydrogen atom or an alkylcarbonyl group having 2 to 6 carbon atoms or an alkyl group having 1 to 6 carbon atoms and optionally substituted with an alkylcarbonylamino group having 2 to 6 carbon atoms and n represents 1 or 2, in which when R3 and R4 each independently represent an alkyl group having 1 to 6 carbon atoms, R1 represents an alkyl group having 1 to 6 carbon atoms and substituted with a hydroxyl group, an amino group or a carboxyl group.

LRRK2IN1 is a highly potent inhibitor of leucine-rich repeat kinase 2 (LRRK2, IC50 = 7.9 nM), an established target for treatment of Parkinson's disease. Two LRRK2IN1 analogues 1 and 2 were synthesised which retained LRRK2 inhibitory activity (1: IC50 = 72 nM; 2: IC50 = 51 nM), were predicted to have improved bioavailability and were efficacious in cell-based models of neuroinflammation. Analogue 1 inhibited IL-6 secretion from LPS-stimulated primary human microglia with EC50 = 4.26 μM. In order to further optimize the molecular properties of LRRK2IN1, a library of truncated analogues was designed based on docking studies. Despite lacking LRRK2 inhibitory activity, these compounds show antineuroinflammatory efficacy at micromolar concentration. The compounds developed were valuable tools in establishing a cell-based assay for assessing anti-neuroinflammatory efficacy of LRRK2 inhibitors. Herein, we present data that IL-1β stimulated U87 glioma cell line is a reliable model for neuroinflammation, as data obtained in this model were consistent with results obtained using primary human microglia and astrocytes.

α7 nicotinic acetylcholine receptor agonists are promising therapeutic candidates for the treatment of cognitive impairment. As a follow up of our internal medicinal chemistry program we investigated a novel series of α7 nAChR agonists. Starting from molecular docking studies on two series of molecules recently developed in our laboratories, an alternative scaffold was designed attempting to combine the optimal features of these previously identified urea and pyrazole compounds. Based on our previous SAR knowledge and on predicted drug-like properties, a small library was synthesized in parallel manner, affording compounds with excellent α7 nAChR activity, selectivity and preliminary ADME profile.
