ARN19702 is a selective, orally active, reversible, and brain-penetrant N-acylethanolamine acid amidase (NAAA) inhibitor with an IC50 of 230 nM for human NAAA. ARN19702 has pain relief effects[1][2].
ARN19702 (3-10 mg/kg; po; daily; for 7 consecutive days) reduces nociception associated with Paclitaxel-induced neuropathy without development of subacute antinociceptive tolerance in male rats[1]. In male mice, ARN19702 (0.1-30 mg/kg; po) attenuates in a dose-dependent manner the spontaneous nocifensive response elicited by intraplantar formalin injection and the hypersensitivity caused by intraplantar carrageenan injection, paw incision, or sciatic nerve ligation[1].. ARN19702 (3-10 mg/kg; po) produces remarkable protective effects against multiple sclerosis in mice[2].Pharmacokinetic properties of ARN19702 in mice 3 mg/kg,i.v 3 mg/kg, p.o.
