Mechanism of action

The exact mechanism of action of eugenol is unknown. However, eugenol has been shown to interrupt action potentials, which may be involved in its anti-pain activity. Research has also shown eugenol to have anti-inflammatory, neuroprotective, antipyretic, antioxidant, antifungal and analgesic properties. ... Thymocyte suspension was irradiated by gamma-rays, and the malondialdehyde (MDA) formation was measured with the thiobarbituric acid reactive species (TBARS) method. The results showed an increase in MDA in irradiated (2 Gy) thymocytes, which was inhibited in samples treated with increasing concentrations of eugenol (10-200 uM) prior to irradiation. The concentration of eugenol required to inhibit half of the MDA formation (IC(50)) in irradiated thymocytes was 100 uM. A dose-dependent increase in the generation of ROS was observed in irradiated thymocytes (0.5-200 cGy) as measured by 2,7-dichlorodihydro fluorescein diacetate (DCH-FDA), which was inhibited by eugenol administered before irradiation. Respiratory inhibition of isolated rat liver mitochondria by eugenol was dose related and uncoupled oxidative phosphorylation from electron transfer. Polymorphonuclear leukocytes (PMNL) play an important role in the modulation of inflammatory conditions in humans. PMNL cells recruited at the site of inflammation, release inflammatory mediators such as leukotrienes, proteolytic enzymes and reactive oxygen species. Among these, leukotrienes are implicated in pathophysiology of allergic and inflammatory disorders like asthma, allergic rhinitis, arthritis, inflammatory bowel disease and psoriasis. 5-lipoxygenase (5-LO) is the key enzyme in biosynthetic pathway of leukotrienes. Our earlier studies showed that spice phenolic active principles significantly inhibit 5-LO enzyme in human PMNLs. In this study we have further characterized the inhibitory mechanism of eugenol, the active principle of spice-clove on 5-LO enzyme and also its effect on leukotriene C((4)) (LTC(4)). Substrate dependent enzyme kinetics showed that the inhibitory effect of eugenol on 5-LO was of a non-competitive nature. Further, eugenol was found to significantly inhibit the formation of LTC(4) in calcium ionophore A23187 and arachidonic acid (AA) stimulated PMNL cells. These data clearly suggest that eugenol inhibits 5-LO by non-competitive mechanism and also inhibits formation of LTC(4) in human PMNL cells and thus may have beneficial role in modulating 5-LO pathway in human PMNL cells. The Ca(2+)-activated Cl(-) channel TMEM16A is involved in epithelial fluid secretion, smooth muscle contraction and neurosensory signaling. We identified a Thai herbal antidiarrheal formulation that inhibited TMEM16A Cl(-) conductance. C18-reversed-phase HPLC fractionation of the herbal formulation revealed >98% of TMEM16A inhibition activity in one out of approximately 20 distinct peaks. The purified, active compound was identified as eugenol (4-allyl-2-methoxyphenol), the major component of clove oil. Eugenol fully inhibited TMEM16A Cl(-) conductance with single-site IC(50)~150 uM. Eugenol inhibition of TMEM16A in interstitial cells of Cajal produced strong inhibition of intestinal contraction in mouse ileal segments. TMEM16A Cl(-) channel inhibition adds to the list of eugenol molecular targets and may account for some of its biological activities.
