ZCZ011 is a brain-penetrant, cannabinoid receptor CB1-selective positive allosteric modulator (PAM) that enhances orthosteric agonist CP55,940, while reduces orthosteric inverse agonist SR141716A, CB1 binding. ZCZ011 potentiates AEA-stimulated GTPγS binding (Emax = 46.5% without vs. 115.2% with 100 nM ZCZ011; mouse brain membranes) and cellular signaling (β-arrestin Emax = 100% without vs.157% with 100 nM ZCZ011, pERK pIC50 = 6.5 without vs. 8.3 with 10 nM ZCZ011; hCB1 cells). ZCZ011 exhibits antinociceptive efficay in murine chronic constriction injury (CCI) model of neuropathic pain & carrageenan model of inflammatory pain (40 mg/kg i.p.) without cannabimimetic side-effects.

The cannabinoid signaling system is found throughout the CNS and its involvement in several pathological processes makes it an attractive therapeutic target. Because orthosteric CB1 cannabinoid receptor ligands have undesirable adverse effects there has been great interest in the development...

The cannabinoid CB1 receptor (CB1R) is an abundant metabotropic G-protein-coupled receptor that has been difficult to address therapeutically because of CNS side effects exerted by orthosteric drug candidates. Recent efforts have focused on developing allosteric modulators that target CB1R. Compounds...

Recently, multiple compounds have been synthesized that target the allosteric binding site(s) of CB1. These CB1 positive allosteric modulators may capture the benefits of cannabinoid receptor activation without unwanted psychoactive effects, such as sedation. For example, ZCZ011 blocks neuropathic pain...

The first generation of CB1 positive allosteric modulators (e.g., ZCZ011) featured a 3-nitroalkyl-2-phenyl-indole structure. Although a small number of drugs include the nitro group, it is generally not regarded as being "drug-like", and this is particularly true for aliphatic nitro...

Cannabis elicits its mood-enhancing and analgesic effects through the cannabinoid receptor 1 (CB1), a G protein-coupled receptor (GPCR) that signals primarily through the adenylyl cyclase-inhibiting heterotrimeric G protein Gi. Activation of CB1-Gi signaling pathways holds potential for treating a number of...
