Due to its unique ability to bind with CB2 receptors, Beta-caryophyllene has potent anti-inflammatory, antimicrobial, antibacterial, and antioxidant properties. It is known to help relieve anxiety and pain, reduce cholesterol, prevent Osteoporosis, and treat seizures BCP was found to elicit a full agonist action on cannabinoid type 2 (CB2) receptors, a G-protein coupled receptor representing important therapeutic target in several diseases. Activation of CB2 receptors notably appeared devoid of psychotropic adverse effect of cannabinoids contrary to the CB1 receptors. In addition, it activates peroxisome proliferated activator receptors (PPARs) isoforms; PPAR-α &-γ and inhibits pathways triggered by the activation of toll like receptor complex; CD14/TLR4/MD2, reduce immuneinflammatory processes and exhibit synergy with µ-opioid receptor dependent pathways. Additionally, it found as potent antagonist of homomeric nicotinic acetylcholine receptors (α7-nAChRs) and devoid of effects mediated by serotonergic and GABAergic receptors. It also modulates numerous molecular targets by altering their gene expression, signaling pathways or through direct interaction. Various pharmacological activities such as cardioprotective, hepatoprotective, gastroprotective, neuroprotective, nephroprotective, antioxidant, anti-inflammatory, antimicrobial and immune-modulator have been reported in experimental studies. It has shown potent therapeutic promise in neuropathic pain, neurodegenerative and metabolic diseases.

Can be a novel candidate for various pathologies considering the polypharmacological and multifaceted therapeutic properties potential along with favorable oral bioavailability, lipophilicity and physicochemical properties.

Iinvestigate in vitro wound healing effects and the anti-inflammatory and antioxidant activities of terpinolene and α-phellandrene. The in vitro stimulatory effects on the proliferation and migration of fibroblasts were assessed using the scratch assay. The anti-inflammatory activity was evaluated using cell-based assays by investigating their influence on nitric oxide (NO), superoxide anion (O2•-), tumour necrosis factor-alpha (TNF-α) and interleukin 6 (IL-6) production and using the TNF-α-induced nuclear factor kappa (NF-κB) assay. Antioxidant activity was determined by the ABTS cation radical scavenging capacity, ferric reducing/antioxidant potential (FRAP), and NO free radical scavenging assays. Terpinolene and α-phellandrene significantly increased the migration and proliferation of fibroblasts and suppressed the pro-inflammatory cytokines IL-6 and TNF-α in a dose-dependent manner. Terpinolene and α-phellandrene at a concentration of 100 μM significantly inhibited NO production (41.3 and 63.8%, respectively) in a macrophage cell-culture-based assay, and resulted in reductions in O2•- production of 82.1 ± 3.5% and 70.6 ± 4.3%, respectively. Moreover, these monoterpenes were verified to suppress NF-κB activity. In summary, terpinolene and α-phellandrene may contribute to broadening clinical options in the treatment of wounds by attenuating inflammation and oxidative stress in vitro.

A few studies also mention the sedative properties of terpinolene, making it a candidate for a natural remedy against insomnia. Its mild yet effective depressant action on the central nervous system could also be applied to the reduction of psychological excitement and anxiety.

α-Humulene, given either orally or by aerosol, exhibited marked anti-inflammatory properties in a murine model of airways allergic inflammation, an effect that seemed to be mediated via reduction of inflammatory mediators, adhesion molecule expression and transcription factors activation.

Humulene Inhibits Acute Gastric Mucosal Injury by Enhancing Mucosal Integrity. Humulene significantly inhibited gastric lesions in HCl/ethanol-induced acute gastritis and decreased gastric acid secretion pyloric ligation-induced gastric ulcers in vivo. In addition, α-humulene reduced the amount of reactive oxygen species and malondialdehyde through upregulation of prostaglandin E2 (PGE2) and superoxide dismutase (SOD). In HMC-1 cells, α-humulene decreased intracellular calcium and increased intracellular cyclic adenosine monophosphate (cAMP) levels, resulting in low histamine levels. α-Humulene also reduced the expression levels of cytokine genes such as interleukin (IL)-1β, IL-6, tumor necrosis factor (TNF) by downregulating nuclear factor-κB (NF-κB) nuclear translocation. Finally, α-humulene upregulated the expression levels of mucin 5AC (Muc5ac), Muc6, trefoil factor 1 (Tff1), trefoil factor 2 (Tff2), and polymeric immunoglobulin receptor (pigr). α-Humulene may attenuate HCl/ethanol-induced gastritis by inhibiting histamine release and NF-κB activation and stimulating antioxidants and mucosal protective factors, particularly Muc5ac and Muc6. Therefore, these data suggest that α-humulene is a potential drug candidate for the treatment of stress-induced or alcoholic gastritis.
