Convolutamydine A has been shown to develop a significant antinociceptive effect. Here we demonstrated that new analogues (5-iodo-3-(2-oxopropyl)-3-hydroxy-2-oxindole (5-Iisa), 5-fluoro-3-(2-oxopropyl)-3-hydroxy-2-oxindole (5-Fisa), 5-chloro-3-(2-oxopropyl)-3-hydroxy-2-oxindole (5-Clisa) and 5-methyl-3-(2-oxopropyl)-3-hydroxy-2-oxindole (5-Meisa)), at 0.1-10mg/kg doses, have significant periphe...
The antinociceptive effects of morusin (1), the main prenylflavonoid present in the Morus nigra root barks have been investigated in classical models of pain in mice. The results showed that 1 exhibits a promising antinociceptive or analgesic profile by the intraperitoneal route, being more potent than some standard drugs used as reference. The mechanism by which the morusin exerts antinocicept...
conclusions the experimental data verified that hebd leaves displayed remarkable antinociceptive activity. furthermore, the nonselective opioid receptor antagonist, naloxone blocked the antinociceptive effect of the extract in all tests, suggesting that hebd may act both at peripheral and central levels. results using writhing, tail-flick, and formalin tests, dramatic antinociceptive effects wer...
Prostatic acid phosphatase (PAP) is expressed in nociceptive neurons and functions as an ectonucleotidase. When injected intraspinally, the secretory isoforms of human and bovine PAP protein have potent and long-lasting antinociceptive effects that are dependent on A(1)-adenosine receptor (A(1)R) activation. In this study, we purified the secretory isoform of mouse (m)PAP using the baculovirus ...
Pistacia vera L., a member of Anacardiaceae family, has been used for sedation and analgesia in traditional medicine. In this study, the antinociceptive and anti-inflammatory effects as well as acute toxicity of the aqueous and ethanolic extracts of P. vera leaves were investigated in mice. The antinociceptive activity was studied using hot plate and writhing tests. The effect of the extracts a...
The antinociceptive effects of ABT-594, a novel nicotinic acetylcholine receptor (nAChR) ligand, were examined in rats in models of acute thermal (hot box) and persistent chemical (formalin test) pain. Also, the effects of ABT-594 treatment on motor function and electroencephalogram (EEG) were determined. In the hot box and formalin test (i.e., phase 1 and 2), acute treatment with ABT-594 (0.03...
Herbal medicine has an old history with a broad application all over the world. Many researches have focused on the curative as well as antinociceptive effects of herbal extract. The aim of this study was to investigate the analgesic effects of Berberis vulgaris hydroethanolic extract (BVE) in male mice. 30 male mice were divided into 5 groups: control, treated by morphine, treated by ...
Our previous study showed that Coriandrum sativum (CS) has antinociceptive effects, but the mechanisms that mediate this effect are not clear. The present study was designed to test the role of opiate system in the antinociceptive effects of CS on acute and chronic pain in mice using Hot Plate (HP), Tail Flick (TF) and Formalin (FT) tests and also to compare its effect with dexamethasone (DE...
PURPOSE The phosphodiesterase 5 inhibitor sildenafil has antinociceptive effects, mediated by an increase in cGMP. This study examined the role of spinal adenosine and serotonin receptors played in the antinociceptive effects of intrathecal sildenafil. MATERIALS AND METHODS Intrathecal catheters were inserted into the subarachnoid space of Sprague-Dawley male rats as a drug delivery device. P...
BACKGROUND Tramadol is an analgesic drug, and its mechanism of action is believed to be mediated by the mu-opioid receptor. A further action of tramadol has been identified as blocking the reuptake of serotonin (5-HT). One of the most recently identified subtypes of 5-HT receptor is the 5-HT7 receptor. Thus, the authors aimed to examine the potential role of serotonergic descending bulbospinal ...
