Overview - CP-x Synthetic Cannabinoids

Description of CP-x Synthetic Cannabinoids

The CP- class of synthetic cannabinoids are named after the company Carl Pfizer where they were first synthesized. CP-55,940 was discovered in 1974 and is one of the most studied member of this class. It binds to the same classical endocannabinoid receptor sites i.e., CB1 and CB2 as THC albeit with stronger efficacies (see receptor binding).

Here we focus on CP-55,940

Other members of the CP-x class include: • CP-47,497 • CP-50,556-1 (aka Levonantradol) • CP-55,244 • CP-945,598 (aka Otenabant) • Plus others

Other Names:

CP Family of Synthetic Cannabinoids

CP-55,940 syn.: CP55,940; CP-55940 plus numerous supplier-based synonyms.

IUPAC Name: 2-[(1R,2R,5R)-5-hydroxy-2-(3-hydroxypropyl)cyclohexyl]-5-(2-methyloctan-2-yl)phenol

Molecular Formula: C24H40O3


CP-x Synthetic Cannabinoids Properties and Effects

CP-55,940 may induce: 

  • Apoptosis in human embryonic rhabdomyosarcoma cell line (Ken-Ichi Tomiyama et al., 2020)

  • Enhancement of cell viability and stimulation of mitochondrial membrane potential (Z. Elmazoglu et. al., 2020)

  • Apoptotic mechanisms in gastric cancer cell lines (A. Ortega et al., 2016)

  • Reduce CB1 protein levels and cell viability in Huntington's disease cell line (R. Laprairie et al., 2016)

  • Reversal of urinary frequency in overactive bladder syndrome (E. Bakali 2016)

  • Apoptosis in glioblastoma cell lines i.e., C6 and U373 (A. Ortega et al., 2015)

  • Analgesic in sickle cell disease (Divyanshoo R. Kohli et al., 2010; David Cain et al., 2013)

  • Reduction of SKF (dopamine D1 receptor agonist)-induced oral dyskinesia (Morten V Madsen et al., 2011)

  • Antagonistic modulation of GPR55 with potential relevance to obesity (A. Kapur et al., 2009)

  • Potent anti-inflammatory effect via a non-CB1/CB2 with potential relevance to rheumatoid arthritis (E. Selvi et al., 2008)

  • Restoration of the integrity of human brain microvascular endothelial cells and the BBB following insults by HIV-1 Gp120 (Tzong-Shi Lu et al., 2008

  • Reduction of radiation-induced emesis (N. Darmani et al., 2007)

  • Co-administration of delta-9-THC with CP 55,940 prevented MDMA-induced hyperthermia instead causing a powerful hypothermia (K. Morley et al., 2004).

CP-x Synthetic Cannabinoids Receptor Binding

Endocannabinoid System (ECS) and CP-55,940: 

  • Agonist at CB1 with a mean Ki at ~0.6nM, which is ~40 times more potent than THC at the same receptor site (Gurney et al., 2014)

  • Agonist at CB2 with a mean Ki at ~0.7nM, which is ~50 times more potent than THC at the same receptor site (Gurney et al., 2014)

Endocannabinoidome (eCBome) and CP-55,940: 

  • PPAR-Gamma with anti-inflammatory responses (S. O'Sullivan 2010)

  • GPR55 antagonist/partial agonist (A. Kapur et al., 2009)

  • 5-HT2A serotonin receptor sites (J. Franklin et al., 2013) 

Ki legend:

  • Full/strong agonist Ki ~1-9nM

  • Moderate agonist Ki ~10-99nM

  • Weak agonist Ki ~100-999nM

  • Very weak agonist Ki ~1,000-up nM

(The reader is reminded that a smaller Ki is associated with the strongest effects.)
