Mentha arvensis essential oil (MaEO) shows repellent efficacy and reduces oxidative stress markers in Nauphoeta cinerea. Its main compounds, menthol and menthone, may offer new analgesic targets.

Area Of Science

  • Pharmacology
  • Entomology
  • Natural Products Chemistry

Background

  • Mentha arvensis, or Japanese mint, is a plant with potential medicinal properties.
  • Essential oils from plants are explored for their biological activities.
  • Oxidative stress plays a role in various physiological and pathological processes.

Purpose Of The Study

  • To evaluate the toxic potential and repellent efficacy of Mentha arvensis essential oil (MaEO) on Nauphoeta cinerea.
  • To investigate the impact of MaEO on biochemical parameters, specifically oxidative stress markers.
  • To explore the potential of MaEO's major compounds as analgesic targets using molecular docking.

Main Methods

  • Gas Chromatography-Mass Spectrometry (GC-MS) for essential oil analysis.
  • Toxicological and repellent assays using varying concentrations of MaEO.
  • Biochemical analysis of lipid peroxidation (LPO), non-protein thiols, and iron(II) levels.
  • Molecular docking simulations for major compound-target protein interactions.

Main Results

  • GC-MS identified menthol (71.31%), menthone (13.34%), and isomentone (5.35%) as major components of MaEO.
  • MaEO demonstrated significant reduction in lipid peroxidation (LPO), non-protein thiols, and iron(II) at 125 mg/mL.
  • L-(-)-Menthol and menthone exhibited high gastrointestinal absorption and target protein affinity in molecular docking.

Conclusions

  • Mentha arvensis essential oil possesses significant toxic and repellent properties against Nauphoeta cinerea.
  • MaEO effectively mitigates oxidative stress by reducing LPO and related markers.
  • The primary components, menthol and menthone, show promise as potential analgesic agents due to their pharmacokinetic and binding properties.

Amines with low molecular weight are usually gaseous at room temperature, while those with high molecular weight are liquid or solids in nature. Usually, low molecular weight amines have a rotten fish-like smell. Diamines typically have a pungent smell. For instance, cadaverine and putrescine, depicted in Figure 1, are two molecules responsible for decaying tissue.

Amines are polar. Accordingly, primary and secondary amines with...

Anticholinesterase Agents: Poisoning and Treatment 01:26

Anticholinesterases, also known as cholinesterase inhibitors, work by blocking the breakdown of acetylcholine, leading to its accumulation in the synaptic cleft. This accumulation indirectly enhances both muscarinic and nicotinic actions. These agents are classified as reversible or irreversible based on their mechanism of action.     
Irreversible agents form a strong bond with the cholinesterase enzyme, making it inactive. The breakdown of the phosphorylated enzyme is...

All meta-directing substituents are deactivating groups. These substituents withdraw electrons from the aromatic ring, making the ring less reactive toward electrophilic substitution. For example, the nitration of nitrobenzene is 100,000 times slower than that of benzene because of the deactivating effect of the nitro group. The first step in an electrophilic aromatic substitution is the addition of an electrophile to form a resonance-stabilized carbocation. The energy diagrams for...

Antimuscarinic drugs block muscarinic receptors in multiple systems, including the gut, eye, smooth muscles, respiratory tract, cardiovascular, and central nervous systems. They produce similar effects with varying selectivity depending on the specific agent and tissue. Here are the key pharmacological actions of antimuscarinics:
Gastrointestinal Effects: Antimuscarinics reduce gut contractions, increase gastric emptying, and slow intestinal transit. They partly inhibit gastric acid secretion...

Cholinergic agonists or cholinomimetics mimic the action of acetylcholine to stimulate the parasympathetic nervous system. They are categorized into direct-acting and indirect-acting agents. The direct-acting cholinergic drugs induce the parasympathetic response by directly binding to the muscarinic or nicotine receptors. In comparison, the indirect-acting cholinergic drugs prevent acetylcholine hydrolysis, indirectly contributing to the extended parasympathetic response.
The direct-acting...
