In the present study the synthesis and antinociceptive activity of bis-vinyl selenides, prepared via FeCl(3) promoted reaction addition of diorganyl dichalcogenides to alkynes, is described. The pharmacological results demonstrated that bis-vinyl selenides 3a, 3d, 3h and 3t elicited antinociceptive effect in the mouse formalin test. The antinociceptive effects of bis-vinyl selenides are not sen...
Acute treatment with the chloroform fraction of Dioclea virgata (Rich.) Amshoff (CFDv) in mice produced decreased ambulation and sedation in the behavioral pharmacological screening. Doses of 125 and 250 mg/kg CFDv decreased latency of sleep onset in the test of sleeping time potentiation. In the open field, animals treated with CFDv reduced ambulation and rearing (250 mg/kg), as well as defeca...
This study aimed to assess the possible topical antinociceptive activity of Vanillosmopsis arborea Baker essential oil (EOVA) and to clarify the underlying mechanism, using the acute model of chemical (eye wiping) nociception in mice. EOVA (25 to 200 mg/kg; p.o. and topical) evidenced significant antinociception against chemogenic pain in the test model of formalin-induced neuroinflammatory pai...
The present work reports the anti-inflammatory and antinociceptive activities of the ethanol extract obtained from the stem bark of Sterculia striata A. St.-Hil. & Naudin (Ss-EtOH) in the experimental models of edema induced by carrageenan, dextran, or histamin and nociception induced by chemical stimuli, such as acetic acid, formalin, capsaicin, or glutamate. The Ss-EtOH (50 mg/kg) promoted a ...
Nociceptin/orphanin FQ (N/OFQ) modulates various biological functions, including nociception, via selective stimulation of the N/OFQ peptide receptor (NOP). Here we used the NOP selective antagonist UFP-101 to characterize the receptor involved in the spinal antinociceptive effects of N/OFQ evaluated in the mouse tail withdrawal assay and to investigate the mechanism underlying this action by a...
BACKGROUND Inhibition of xanthine oxidase by allopurinol increases hypoxanthine and xanthine, which are converted to purines, including the inhibitory neuromodulator adenosine. AIM We aimed to investigate the antinociceptive effects of allopurinol in thermal and chemical pain models in mice and to evaluate its possible antinociceptive mechanism by using selective adenosine receptors A1, A2A a...
Exposure of mice to the anesthetic gas N2O evokes a prominent antinociceptive effect that is sensitive to antagonism by nonselective nitric-oxide synthase (NOS) inhibitors. The present study was conducted to identify whether a specific NOS isoform is implicated in N2O antinociception in mice. In the abdominal constriction test, exposure of mice to 25, 50, and 70% N2O resulted in a concentration...
Sex-related differences in the perception and modulation of pain have been reported. The present study is the first to investigate systematically whether activation of opioid receptor-like 1 receptor (ORL1) by orphanin FQ (OFQ) produces sex-specific modulation of spinal nociception and whether estrogen or testosterone contributes to these differences using the rat as an experimental animal. Two...
Analgesic and Anti-Inflammatory Activities of Leaf Extract of Mallotus repandus (Willd.) Muell. Arg.
In folk medicine Mallotus repandus (Willd.) Muell. Arg. is used to treat muscle pain, itching, fever, rheumatic arthritis, snake bite, hepatitis, and liver cirrhosis. This study aimed to evaluate the antinociceptive as well as the anti-inflammatory activities of the methanol extract of leaf. The leaves were extracted with methanol following hot extraction and tested for the presence of phytoche...
The literature shows that the monoterpenes are great candidates for the development of new drugs for the treatment of various pathological processes, including painful conditions. The gamma terpinene (γ-TPN) is a monoterpene present in plant species that have multiple pharmacological properties and has structural similarity to antinociceptive monoterpenes, such as limonene and alpha-phellandren...
