JZL 195

JZL 195 is a highly selective and irreversible dual inhibitor of fatty acid amide hydrolase (FAAH) and monoacylglycerol lipase (MAGL), with IC₅₀ values of 2nM and 4nM, respectively^[1]. In vivo, JZL 195 elevates the levels of endogenous cannabinoids anandamide (AEA) and 2-arachidonoylglycerol (2-AG)^[2]. JZL 195 is commonly used to alleviate neuropathic and inflammatory pain, manage chemotherapy-induced peripheral neuropathy, and investigate potential antihypertensive effects, among other applications^[3,4].

In vitro, pretreatment of immortalized human renal proximal tubular HK-2 cells with 250nM JZL 195 for 24h indirectly activated CB₁R and significantly increased the mRNA and protein expression levels of erythropoietin (EPO)^[5].

In vivo, oral administration of JZL 195 (20mg/kg) for 15 days in a streptozotocin-induced sporadic Alzheimer's disease mouse model significantly reversed the elevated levels of Aβ_1-42 in hippocampal tissue^[6]. Intraperitoneal injection of JZL 195 (3mg/kg) 2h after nitroglycerin (NTG) administration in Sprague-Dawley rats, with tissue sampling following behavioral tests, significantly reduced the NTG-induced increase in calcitonin gene-related peptide (CGRP) levels^[7]. Intraperitoneal administration of JZL 195 (10mg/kg) 45min before bilateral carotid artery occlusion surgery in C3H mice significantly ameliorated ischemia-induced neurological deficits^[8].
