Researchers report the synthesis of terminally fluorinated HU-210 and HU-211 analogues (HU-210F and HU-211F, respectively) and their biological evaluation as ligands of cannabinoid receptors (CB1 and CB2) and N-methyl d-aspartate receptor (NMDAR). [18F]-labelled HU-210F was radiosynthesised from the bromo-substituted precursor. In vitro assays showed that both HU-210F and HU-211F retain the potent pharmacological profile of HU-210 and HU-211, suggesting that [18F]-radiolabelled HU-210F and HU-211F could have potential as PET tracers for in vivo imaging.[1]
CB receptor agonist HU-210 exhibits an infarction-limiting effect during in vitro reperfusion of the heart after focal ischemia. This effect is paralleled by a decrease in left-ventricular developed pressure and double product. In addition, HU-210 reduces end-diastolic pressure during the reperfusion period, which indirectly attests to reduced Ca2+ overload of cardiomyocytes[3]. |
| ln Vivo |
Upon DSS challenge, mice suffered from bloody stool, colon shortening, intestinal mucosa edema, pro-inflammatory cytokine increase and intestinal barrier destruction with goblet cell depletion, increased intestinal microflora accompanied with elevated plasma lipopolysaccharide, reduced mRNA expression of the intestinal tight junction proteins, and abnormal ratio of CD4+/CD8+ T cells in the intestinal Peyer's patches. Pro-inflammatory cytokines in the plasma and the lung, as well as pulmonary myeloperoxidase activity, indicators of extraintestinal inflammation were increased. Protein expression of p38α and pp38 was up-regulated in the colon of WT mice. Tlr4 -/- mice showed milder colitis. HU210 reversed the intestinal barrier changes in both strains of mice, but alleviated inflammation only in WT mice.
Conclusions: Our study indicates that in experimental colitis, HU210 displays a protective effect on the intestinal barrier function independently of the TLR4 signaling pathway; however, in the extraintestinal tissues, the anti-inflammatory action seems through affecting TLR4-mediated p38 mitogen-activated protein kinase pathway [2].

| Animal Protocol |
Background: Ulcerative colitis (UC) is strongly associated with inflammation and intestinal barrier disorder. The nonselective cannabinoid receptor agonist HU210 has been shown to ameliorate inflamed colon in colitis, but its effects on intestinal barrier function and extraintestinal inflammation are unclear. [2]
Aims: To investigate the effects and the underlying mechanism of HU210 action on the UC in relation to a role of TLR4 and MAP kinase signaling. [2] Methods: Wild-type (WT) and TLR4 knockout (Tlr4 -/-) mice were exposed to 4% dextran sulfate sodium (DSS) for 7 days. The effects of HU210 on inflammation and intestinal barrier were explored.

| Additional Infomation |
Dexanabinol is a 1-benzopyran.
Dexanabinol is a synthetic, terpene-based cannabinoid derivative devoid of cannabinoid receptors 1 and 2 agonist activity and with potential neuroprotective, antiinflammatory and antineoplastic activities. Functioning as an N-Methyl-D-aspartate (NMDA) receptor antagonist, dexanabinol protects neuronal cells against NMDA and glutamate neurotoxicity. This agent also scavenges peroxy radicals and protects neurons from the damages of reactive oxygen species. Furthermore, dexanabinol inhibits the activity of nuclear factor kappa B (NF-kB), thereby preventing the expression of NF-kB target genes, such as tumor necrosis factor alpha, cytokines and inducible nitric oxide synthase. As a result, this agent may restore apoptotic processes in cancerous cells. NF-kB is activated in a variety of cancer cells and plays a key role in the regulation of apoptosis and cellular proliferation. Drug Indication Investigated for use/treatment in traumatic brain injuries and neurologic disorders. |
