Fenchone Derivatives as a Novel Class of CB2 Selective Ligands: Design, Synthesis, X-ray Structure and Therapeutic Potential
Molecules 2022 Feb 18;27(4):1382.PMID:35209170DOI:10.3390/molecules27041382.
A series of novel cannabinoid-type derivatives were synthesized by the coupling of (1S,4R)-(+) and (1R,4S)-(-)-fenchones with various resorcinols/phenols. The fenchone-resorcinol derivatives were fluorinated using Selectfluor and demethylated using sodium ethanethiolate in dimethylformamide (DMF). The absolute configurations of four compounds were determined by X-ray single crystal diffraction. The fenchone-resorcinol analogs possessed high affinity and selectivity for the CB2 cannabinoid receptor. One of the analogues synthesized, 2-(2',6'-dimethoxy-4'-(2″-methyloctan-2″-yl)phenyl)-1,3,3-trimethylbicyclo[2.2.1]heptan-2-ol (1d), had a high affinity (Ki = 3.51 nM) and selectivity for the human CB2 receptor (hCB2). In the [35S]GTPγS binding assay, our lead compound was found to be a highly potent and efficacious hCB2 receptor agonist (EC50 = 2.59 nM, E(max) = 89.6%). Two of the fenchone derivatives were found to possess anti-inflammatory and analgesic properties. Molecular-modeling studies elucidated the binding interactions of 1d within the CB2 binding site.
Metabolism of (+)-Fenchone by CYP2A6 and CYP2B6 in human liver microsomes
Biol Pharm Bull 2006 Dec;29(12):2354-8.PMID:17142962DOI:10.1248/bpb.29.2354.
The in vitro metabolism of (+)-Fenchone was examined in human liver microsomes and recombinant enzymes. Biotransformation of (+)-Fenchone was investigated by gas chromatography-mass spectrometry. (+)-Fenchone was found to be oxidized to 6-exo-hydroxyfenchone, 6-endo-hydroxyfenchone and 10-hydroxyfenchone by human liver microsomal P450 enzymes. The formation of metabolite of (+)-Fenchone was determined by relative abundance of mass fragments and retention time with GC. CYP2A6 and CYP2B6 in human liver microsomes were major enzymes involved in the hydroxylation of (+)-Fenchone, based on the following lines of evidence. First, of eleven recombinant human P450 enzymes tested, CYP2A6 and CYP2B6 catalyzed oxidation of (+)-Fenchone. Second, oxidation of (+)-Fenchone was inhibited by thioTEPA, (+)-menthofuran anti-CYP2A6 and anti-CYP2B6 antibodies. Finally, there was a good correlation between CYP2A6, CYP2B6 contents and (+)-Fenchone hydroxylation activities in liver microsomes of 8 human samples.
Metabolism of (-)-Fenchone by CYP2A6 and CYP2B6 in human liver microsomes
Xenobiotica 2007 Feb;37(2):194-204.PMID:17484521DOI:10.1080/00498250600917256.
The in vitro metabolism of (-)-Fenchone was examined in human liver microsomes and recombinant enzymes. The biotransformation of (-)-Fenchone was investigated by gas chromatography-mass spectrometry. (-)-Fenchone was found to be oxidized to 6-exo-hydroxyfenchone, 6-endo-hydroxyfenchone and 10-hydroxyfenchone by human liver microsomal P450 enzymes. The formation of metabolites was determined by the relative abundance of mass fragments and retention times on gas chromatography (GC). CYP2A6 and CYP2B6 were major enzymes involved in the hydroxylation of (-)-Fenchone by human liver microsomes, based on the following lines of evidence. First, of 11 recombinant human P450 enzymes tested, CYP2A6 and CYP2B6 catalysed the oxidation of (-)-Fenchone. Second, oxidation of (-)-Fenchone was inhibited by thioTEPA and (+)-menthofuran. Finally, there was a good correlation between CYP2A6, CYP2B6 contents and (-)-Fenchone hydroxylation activities in liver microsomes of 11 human samples. CYP2A6 may be more important than CYP2B6 in human liver microsomes. Kinetic analysis showed that the Vmax/Km values for (-)-Fenchone 6-endo-, 6-exo- and 10-hydroxylation catalysed by liver microsomes of human sample HG-03 were 24.3, 44.0 and 1.3nM(-1)min(-1) , respectively. Human recombinant CYP2A6 and CYP2B6 catalysed (-)-Fenchone 6-exo-hydroxylation with Vmax values of 2.7 and 12.9 nmol min(-1) nmol(-1) P450 and apparent Km values of 0.18 and 0.15 mM and (-)-Fenchone 6-endo-hydroxylation with Vmax values of 1.26 and 5.33nmolmin(-l) nmol(-1) P450 with apparent Km values of 0.29 and 0.26mM. (-)-Fenchone 10-hydroxylation was catalysed by CYP2B6 with Km and Vmax values of 0.2 mM and 10.66 nmol min(-1) nmol(-1) P450, respectively.
Antifungal activity and antidiarrheal activity via antimotility mechanisms of (-)-Fenchone in experimental models
World J Gastroenterol 2020 Nov 21;26(43):6795-6809.PMID:33268962DOI:10.3748/wjg.v26.i43.6795.
Background: (-)-Fenchone is a bicyclic monoterpene present in essential oils of plant species, such as Foeniculum vulgare and Peumus boldus, used to treatment of gastrointestinal diseases. Pharmacological studies report its anti-inflammatory, antioxidant, and antinociceptive activity. Aim: To investigate antidiarrheal activity related to gastrointestinal motility, intestinal secretion and antimicrobial activity. Methods: A castor oil-induced diarrhea model was used to evaluate antidiarrheal activity. Intestinal transit and gastric emptying protocols were used to assess a possible antimotility effect. Muscarinic receptors, presynaptic α2-adrenergic and tissue adrenergic receptors, KATP channels, nitric oxide were investigated to uncover antimotility mechanisms of action and castor oil-induced enteropooling to elucidate antisecretory mechanisms. The antimicrobial activity was evaluated in the minimum inhibitory concentration model, the fractional inhibitory concentration index using the (-)-Fenchone association method with standard antifungal agents. Results: (-)-Fenchone (75, 150 and 300 mg/kg) showed antidiarrheal activity, with a significant decrease in the evacuation index. This activity is possibly related to a percentage of reduced intestinal transit (75, 150 and 300 mg/kg). The antimotility effect of (-)-Fenchone decreased in the presence of pilocarpine, yohimbine, propranolol, L-NG-nitroarginine methyl ester or glibenclamide. In the enteropooling model, no reduction in intestinal fluid weight was observed. (-)- Fenchone did not show antibacterial activity; on the other hand, inhibits the growth of strains of fungi with a minimum fungicide concentration of 32 μg/mL. However, when it was associated with amphotericin B, no synergism was observed. Conclusion: The antidiarrheal effect of (-)-Fenchone in this study involves antimotility effect and not involve antisecretory mechanisms. (-)-Fenchone presents antifungal activity; however, it did not show antibacterial activity.
Design, Synthesis, and Biological Evaluation of (+)-Camphor- and (-)-Fenchone-Based Derivatives as Potent Orthopoxvirus Inhibitors
ChemMedChem 2022 Jun 20;17(12):e202100771.PMID:35388614DOI:10.1002/cmdc.202100771.
In this work, a library of (+)-camphor and (-)-Fenchone based N-acylhydrazones, amides, and esters, including para-substituted aromatic/hetaromatic/cyclohexane ring was synthesized, with potent orthopoxvirus inhibitors identified among them. Investigations of the structure-activity relationship revealed the significance of the substituent at the para-position of the aromatic ring. Also, the nature of the linker between a hydrophobic moiety and aromatic ring was clarified. Derivatives with p-Cl, p-Br, p-CF3, and p-NO2 substituted aromatic ring and derivatives with cyclohexane ring showed the highest antiviral activity against vaccinia virus, cowpox, and ectromelia virus. The hydrazone and the amide group were more favourable as a linker for antiviral activity than the ester group. Compounds 3 b and 7 e with high antiviral activity were examined using the time-of-addition assay and molecular docking study. The results revealed the tested compounds to inhibit the late processes of the orthopoxvirus replication cycle and the p37 viral protein to be a possible biological target.
