Mechanism of action

Butylated hydroxyanisole (BHA) and butylated hydroxytoluene (BHT) act as antioxidants by inhibiting the oxidation of lipids. They scavenge free radicals and donate hydrogen atoms to reactive species, thus stabilizing and preventing oxidative damage to cellular components. This action helps to protect the integrity of cell membranes and prevent the formation of harmful peroxides.

Pharmacodynamics

The pharmacodynamic properties of butylated compounds are primarily related to their antioxidant activity. They exhibit a dose-dependent ability to inhibit lipid peroxidation, which is crucial in protecting cells from oxidative stress. Furthermore, they may modulate certain biochemical pathways involved in cell signaling and apoptosis, although these effects are less well-characterized.

Pharmacokinetics

Butylated compounds are absorbed from the gastrointestinal tract following oral ingestion. They undergo metabolic processing primarily in the liver, where they are conjugated and excreted in urine. The half-life of butylated compounds in humans is variable, influenced by factors such as dosage and individual metabolism. Accumulation in tissues is generally low, but prolonged exposure may lead to higher tissue concentrations.

Adults: For topical application, camphor is usually applied as needed to the affected area, following the instructions on the specific product used. Consult the product label or a healthcare professional for detailed dosing guidelines.

Mechanism of action

Camphor activates the transient receptor potential vanilloid 1 (TRPV1) and TRPV3 channels, which are involved in sensing pain and temperature. It requires higher concentrations to activate TRPV1 compared to capsaicin but notably desensitizes TRPV1 more rapidly and completely. This action is enhanced under inflamed conditions through phospholipase C-coupled receptor stimulation. The distinct activation pathways of camphor contribute to its analgesic effects, making it effective in reducing pain sensitivity.

Pharmacodynamics

The pharmacodynamic properties of camphor are primarily related to its interaction with TRPV1 and TRPV3 channels. By activating these receptors, camphor induces a sensation of warmth and can result in analgesia through sensory nerve excitation and subsequent desensitization. This mechanism is similar to that of other topical analgesics like capsaicin and menthol but is characterized by a faster desensitization of TRPV1. Additionally, camphor's effects may include local vasodilation and increased blood flow to the area of application, which can further alleviate pain and inflammation.

Pharmacokinetics

Camphor is absorbed through the skin when applied topically. Its pharmacokinetic profile involves distribution to various tissues, where it can exert local effects. The metabolism of camphor occurs primarily in the liver, and it is eliminated from the body mainly through urine.

Indications

• Uncomplicated malaria caused by Plasmodium falciparum

Dosage

Children: Refer to the BNF for Children for appropriate dosing in paediatric patients.

Adults: Refer to the BNF for specific dosing recommendations.

Mechanism of action

Piperaquine acts by interfering with the heme detoxification process in the malaria parasite. It accumulates within the food vacuole of the parasite and inhibits the conversion of toxic heme into non-toxic hemozoin. This accumulation of free heme leads to oxidative stress and cellular damage, ultimately resulting in the death of the parasite.

Pharmacodynamics

Piperaquine demonstrates a dose-dependent response in its antimalarial activity. It is effective against the asexual blood stages of Plasmodium species, with a prolonged half-life that allows for once-weekly dosing in some regimens. The drug's efficacy is influenced by the rate of parasite clearance and the patient's immune response.

Pharmacokinetics

Piperaquine is well-absorbed following oral administration, with peak plasma concentrations typically occurring within 4 to 6 hours. It has a long elimination half-life, which can range from 10 to 30 days, allowing for sustained plasma levels. The drug is metabolized in the liver and excreted primarily in the feces, with a smaller fraction eliminated in the urine. Its pharmacokinetics can be significantly affected by drug interactions, particularly those that alter hepatic metabolism.

Mechanism of action

Thymol modulates macrophage activity by enhancing phagocytosis and increasing the proliferation of splenocytes, acting as a mitogen. It improves macrophage uptake capacity through increased membrane fluidity and enhances lysosomal activity. Thymol also stimulates the respiratory burst in macrophages, leading to increased generation of superoxide anions. Additionally, it shows anti-inflammatory effects by decreasing the secretion of pro-inflammatory cytokines such as TNF-alpha, IL-1beta, and PGE(2).

Pharmacodynamics

Thymol exhibits various pharmacodynamic effects including antimicrobial, antifungal, and immunomodulatory activities. Its ability to enhance macrophage function suggests a role in boosting the immune response, potentially benefiting conditions characterized by immune dysfunction. The compound also demonstrates antioxidant properties, contributing to its anti-inflammatory effects.

Pharmacokinetics

The pharmacokinetic profile of thymol is not fully characterized; however, it is known to be readily absorbed and distributed in the body due to its lipophilic nature. Metabolism occurs in the liver, with excretion primarily through the urine. The exact half-life and elimination pathways require further investigation to provide a comprehensive overview.

Mechanism of action

Counter-irritation is thought to be effective at alleviating musculoskeletal pain as the irritation of the sensory nerve endings alters or offsets pain in the underlying muscle or joints served by the same nerves. When applied topically, methyl salicylate penetrates the skin and underlying tissues, where it reversibly inhibits cyclooxygenase enzyme and prevents the production of inflammatory mediators such as prostaglandin and thromboxane A2.

Pharmacodynamics

Methyl salicylate relieves musculoskeletal pain in muscles, joints, and tendons by causing irritation and reddening of the skin due to dilated capillaries and increased blood flow. It acts as a rubefacient and skin irritant, providing a soothing sensation of warmth. Its pharmacological profile is similar to that of aspirin and other NSAIDs.

Mechanism of action

Camphor is a naturally occurring compound that is used as a major active ingredient of balms and liniments supplied as topical analgesics. ... Capsaicin and menthol, two other topically applied agents widely used for similar purposes, are known to excite and desensitize sensory nerves by acting on two members of transient receptor potential (TRP) channel superfamily: heat-sensitive TRP vanilloid subtype 1 (TRPV1) and cold-sensitive TRP channel M8, respectively. Camphor has recently been shown to activate TRPV3, and here /investigators/ show that camphor also activates heterologously expressed TRPV1, requiring higher concentrations than capsaicin. Activation was enhanced by phospholipase C-coupled receptor stimulation mimicking inflamed conditions. Similar camphor-activated TRPV1-like currents were observed in isolated rat DRG neurons and were strongly potentiated after activation of protein kinase C with phorbol-12-myristate-13-acetate. Camphor activation of rat TRPV1 was mediated by distinct channel regions from capsaicin, as indicated by camphor activation in the presence of the competitive inhibitor capsazepine and in a capsaicin-insensitive point mutant. Camphor did not activate the capsaicin-insensitive chicken TRPV1. TRPV1 desensitization is believed to contribute to the analgesic actions of capsaicin. /The authors/ found that, although camphor activates TRPV1 less effectively, camphor application desensitized TRPV1 more rapidly and completely than capsaicin. Conversely, TRPV3 current sensitized after repeated camphor applications, which is inconsistent with the analgesic role of camphor. /Investigators/ also found that camphor inhibited several other related TRP channels, including ankyrin-repeat TRP 1 (TRPA1). The camphor-induced desensitization of TRPV1 and block of TRPA1 may underlie the analgesic effects of camphor.

Mechanism of action

Curcumin acts as a scavenger of oxygen species, such as hydroxyl radical, superoxide anion, and singlet oxygen and inhibit lipid peroxidation as well as peroxide-induced DNA damage. Curcumin mediates potent anti-inflammatory agent and anti-carcinogenic actions via modulating various signalling molecules. It suppresses a number of key elements in cellular signal transduction pathways pertinent to growth, differentiation, and malignant transformation; it was demonstrated _in vitro_ that curcumin inhibits protein kinases, c-Jun/AP-1 activation, prostaglandin biosynthesis, and the activity and expression of the enzyme cyclooxygenase (COX)-2. Curcumin, a polyphenolic natural product, exhibits therapeutic activity against a number of diseases, attributed mainly to its chemical structure and unique physical, chemical, and biological properties. It is a diferuloyl methane molecule [1,7-bis (4-hydroxy-3- methoxyphenyl)-1,6-heptadiene-3,5-dione)] containing two ferulic acid residues joined by a methylene bridge. It has three important functionalities: an aromatic o-methoxy phenolic group, alpha, beta-unsaturated beta-diketo moiety and a seven carbon linker. Extensive research in the last two decades has provided evidence for the role of these different functional groups in its crucial biological activities. A few highlights of chemical structural features associated with the biological activity of curcumin are: The o-methoxyphenol group and methylenic hydrogen are responsible for the antioxidant activity of curcumin, and curcumin donates an electron/ hydrogen atom to reactive oxygen species. Curcumin interacts with a number of biomolecules through non-covalent and covalent binding. The hydrogen bonding and hydrophobicity of curcumin, arising from the aromatic and tautomeric structures along with the flexibility of the linker group are responsible for the non-covalent interactions. The alpha, beta-unsaturated beta-diketone moiety covalently interacts with protein thiols, through Michael reaction. The beta-diketo group forms chelates with transition metals, thereby reducing the metal induced toxicity and some of the metal complexes exhibit improved antioxidant activity as enzyme mimics. New analogues with improved activity are being developed with modifications on specific functional groups of curcumin... The present study demonstrates that curcumin acts as pro-oxidant and sensitizes human lung adenocarcinoma epithelial cells (A549) to apoptosis via intracellular redox status mediated pathway. Results indicated that curcumin induced cell toxicity (light microscopy and MTT assay) and apoptosis (AnnexinV-FITC/PI labeling and caspase-3 activity) in these cells. These events seem to be mediated through generation of reactive oxygen species (ROS) and superoxide radicals (SOR) and enhanced levels of lipid peroxidation. These changes were accompanied by increase in oxidized glutathione (GSSG), reduced glutathione (GSH) and gamma-glutamylcysteine synthetase (gamma-GCS) activity, but decrease in GSH/GSSG ratio. The induction of apoptosis and decrease in GSH/GSSG ratio was also accompanied by sustained phosphorylation and activation of p38 mitogen activated protein kinase (MAPK). On the other hand, addition of N-acetyl cysteine (NAC), an antioxidant, blocked the curcumin-induced ROS production and rescued malignant cells from curcumin-induced apoptosis through caspase-3 deactivation. However, L-buthionine sulfoximine (BSO), a GSH synthesis blocking agent, further enhanced curcumin-induced ROS production and apoptosis in A549 cells. Decreased GSH/GSSG ratio seems to be a crucial factor for the activation of MAPK signaling cascade by curcumin. The study therefore, provides an insight into the molecular mechanism involved in sensitization of lung adenocarcinoma cells to apoptosis by curcumin. Curcumin has many pharmaceutical applications, many of which arise from its potent antioxidant properties. The present research examined the antioxidant activiti

Pharmacodynamics

Intravenous application of 25 mg/kg bw curcumin to rats resulted in an increase in bile flow by 80 and 120%. In the rat model of inflammation, curcumin was shown to inhibit edema formation. In nude mouse that had been injected subcutaneously with prostate cancer cells, administration of curcumin caused a marked decrease in the extent of cell proliferation, a significant increase of apoptosis and micro-vessel density. Curcumin may exert choleretic effects by increasing biliary excretion of bile salts, cholesterol, and bilirubin, as well as increasing bile solubility. Curcumin inhibited arachidonic acid-induced platelet aggregation _in vitro_.

Mechanism of action

Benzyl alcohol inhibits lice from closing their respiratory spiracles, allowing the vehicle to obstruct the spiracles and causing the lice to asphyxiate.

Mechanism of action

Exposure to low temperatures often causes allergic responses or urticaria. Similarly, menthol, a common food additive is also known to cause urticaria, asthma, and rhinitis. However, despite the obvious clinical implications, the molecular mechanisms responsible for inducing allergic responses to low temperatures and menthol have not been determined. Because a non-selective cation channel, transient receptor potential subtype M8 (TRPM8) is activated by cold and menthol, we hypothesized that this channel mediates cold- and menthol-induced histamine release in mast cells. Here, we report that TRPM8 is expressed in the basophilic leukemia mast cell line, RBL-2H3, and that exposure to menthol or low temperatures induced Ca(2+) influx in RBL-2H3 cells, which was reversed by a TRPM8 blocker. Furthermore, menthol, a TRPM8 agonist, induced the dose-dependent release of histamine from RBL-2H3 cells. When TRPM8 transcripts were reduced by siRNA (small interfering RNA), menthol- and cold-induced Ca(2+) influx and histamine release were significantly reduced. In addition, subcutaneous injection of menthol evoked scratching, a typical histamine-induced response which was reversed by a TRPM8 blocker. Thus, our findings indicate that TRPM8 mediates the menthol- and cold-induced allergic responses of mast cells, and suggest that TRPM8 antagonists be viewed as potential treatments for cold- and menthol-induced allergies. /DL-Menthol/ Menthol's characteristic cooling sensation is due, in part, to the activation of sensory neurons generally termed transient receptor potential (TRP) channels, in particular transient receptor potential melastatin family member 8 (TRPM8) and transient receptor potential subfamily A, member 1 (TRPA1). Menthol acts upon TRPM8 receptors by rapidly increasing intracellular calcium and mobilizing calcium flux through the channels to induce cold response signals at the application site. Aside from its cold-inducing sensation capabilities, menthol exhibits cytotoxic effects in cancer cells, induces reduction in malignant cell growth, and engages in synergistic excitation of GABA receptors and sodium ion channels resulting in analgesia. /DL-Menthol/ In recent years, the transient receptor potential melastatin member 8 (TRPM8) channel has emerged as a promising prognostic marker and putative therapeutic target in prostate cancer. We have found that forced overexpression of TRPM8 in PC-3 cells can inhibit the cell proliferation and motility probably through the TRPM8 activation. In this study, we aimed to investigate whether activating the TRPM8 channel by its selective agonist menthol can inhibit the proliferation and motility of androgen-independent prostate cancer (AIPC) with remarkable expression of TRPM8. Menthol is a naturally occurring compound, which has been widely used in cosmetics and pharmaceutical products, and also as flavoring in food. DU145 cells are androgen-independent but have a remarkable expression of TRPM8. The demonstration of the existence of TRPM8 and the absence of TRPA1 in DU145 cells provided the foundation for the following experiments, because both TRPM8 and TRPA1 are molecular targets of menthol. The outcome of MTT assay indicated that menthol inhibited the cell growth (p < 0.01). Cell cycle distribution and scratch assay analysis revealed that menthol induced cell cycle arrest at the G(0)/G(1) phase (p < 0.01). Furthermore, menthol inhibited the migration of DU145 cells by downregulating the focal-adhesion kinase. So it suggests that the activation of the existing TRPM8 channels may serve as a potential and pragmatic treatment for those AIPC with remarkable expression of TRPM8, and menthol is a useful compound for future development as an anticancer agent. /DL-Menthol/

Mechanism of action

The potent role of thymol, a natural compound, in modulation of macrophage activity was evaluated by determining all the sequential steps involved during phagocytosis. We found a significant increase in the proliferation of splenocytes in the presence of thymol and it proved to be a good mitogen. Uptake capacity of macrophages was enhanced due to increased membrane fluidity after treatment with thymol and it also increases lysosomal activity of macrophages. Data of superoxide anion generation revealed the involvement of thymol in the generation of respiratory burst as it potentiated this property of macrophages at a concentration of 150 uM. In the case of TNF-a, IL-1beta and PGE(2) a decreased level of secretion was observed 154 pg/mL, 736.1 pg/mL, and 151 pg/mL respectively when compared with lipopolysaccharide treated cells, where the level of these cytokines was significantly high. We also determined the anti-complementary activity of thymol which showed to be more effective than rosmarinic acid. Thus, the results obtained from the study suggest the potential role of thymol as a natural immunostimulatory drug which can be used in the treatment of various immunological disorders.

Mechanism of action

Counter-irritation is thought to be effective at alleviating musculoskeletal pain as the irritation of the sensory nerve endings is thought to alter or offset pain in the underlying muscle or joints that are served by the same nerves. This is thought to mask the underlying musculoskeletal pain and discomfort. When applied topically, methyl salicylate is thought to penetrate the skin and underlying tissues where it reversibly inhibits cyclooxygenase enzyme and locally and peripherally prevents the production of inflammatory mediators such as prostaglandin and thromboxane A2.

Pharmacodynamics

Methyl salicylate relieve musculoskeletal pain in the muscles, joints, and tendons by causing irritation and reddening of the skin due to dilated capillaries and increased blood flow. It is pharmacologically similar to aspirin and other NSAIDs but as a topical agent it primarily acts as a rubefacient and skin irritant. Counter-irritation is believed to cause a soothing sensation of warmth.
