Abstract
Berberine is an isoquinoline alkaloid naturally produced by several types of plants. Berberine has extensive pharmacological effects, such as anti-diabetic, anti-inflammatory, and antioxidant effects. In the current study, we assess the antinociceptive effects of berberine and its association with the l -arginine ( l -Arg)/NO/cGMP/K ATP channel pathway via intraplantar administration in rats. To examine the antinociceptive properties of berberine, the formalin test was conducted. The number of rat paw flinches was counted for an h. l -Arg (precursor of nitric oxide, 3-30 μ g/paw), l -NAME (NO synthase inhibitor, 10 and 100 μ g/paw), methylene blue (guanylyl cyclase inhibitor, 100 and 200 μ g/paw), and glibenclamide (ATP-sensitive potassium channel blocker, 10 and 30 μ g/paw) were locally injected, respectively, into the right hind paws of rats as a pre-treatment before berberine injection to understand how the l -Arg/NO/cGMP/K ATP pathway plays a role in the antinociceptive effect of berberine. The ipsilateral injection of berberine into the right paw (0.1-10 0 μ g/paw) showed a dose-dependent antinociceptive effect in both the first and second phases of the formalin test, almost similar to morphine (25 μ g/paw). Intraplantar injection of l -Arg (30 µg/paw) increased the antinociceptive effect of berberine in the second phase. In addition, injection of l -NAME, methylene blue, and glibenclamide caused a reduction in the antinociceptive effect of berberine throughout the second phase in a dose-dependent manner. However, the antinociceptive effects of berberine in the first phase of the rat formalin test were not affected by this pathway. As a novel local antinociceptive agent, berberine can exert a peripheral antinociceptive effect via the l -Arg/NO/cGMP/K ATP channel pathway.

Bedair AF, Wahid A, El-Mezayen NS, El-Yazbi AF, Khalil HA, Hassan NW, Afify EA. Nicorandil/ morphine crosstalk accounts for antinociception and hepatoprotection in hepatic fibrosis in rats: Distinct roles of opioid/cGMP and NO/KATP pathways. Biomed Pharmacother 2023; 165:115068. [PMID: 37392650 DOI: 10.1016/j.biopha.2023.115068] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/11/2023] [Revised: 06/20/2023] [Accepted: 06/23/2023] [Indexed: 07/03/2023] Open
Abstract
Previous report indicated that nicorandil potentiated morphine antinociception and attenuated hepatic injury in liver fibrotic rats. Herein, the underlying mechanisms of nicorandil/morphine interaction were investigated using pharmacological, biochemical, histopathological, and molecular docking studies. Male Wistar rats were injected intraperitoneally (i.p.) with carbon tetrachloride (CCl4, 40%, 2 ml/kg) twice weekly for 5 weeks to induce hepatic fibrosis. Nicorandil (15 mg/kg/day) was administered per os (p.o.) for 14 days in presence of the blockers; glibenclamide (KATP channel blocker, 5 mg/kg, p.o.), L-NG-nitro-arginine methyl ester (L-NAME, nitric oxide synthase inhibitor, 15 mg/kg, p.o.), methylene blue (MB, guanylyl cyclase inhibitor, 2 mg/kg, i.p.) and naltrexone (opioid antagonist, 20 mg/kg, i.p.). At the end of the 5th week, analgesia was evaluated using tail flick and formalin tests along with biochemical determinations of liver function tests, oxidative stress markers and histopathological examination of liver tissues. Naltrexone and MB inhibited the antinociceptive activity of the combination. Furthermore, combined nicorandil/morphine regimen attenuated the release of endogenous peptides. Docking studies revealed a possible interaction of nicorandil on µ, κ and δ opioid receptors. Nicorandil/morphine combination protected against liver damage as evident by decreased liver enzymes, liver index, hyaluronic acid, lipid peroxidation, fibrotic insults, and increased superoxide dismutase activity. Nicorandil/morphine hepatoprotection and antioxidant activity were inhibited by glibenclamide and L-NAME but not by naltrexone or MB. These findings implicate opioid activation/cGMP versus NO/KATP channels in the augmented antinociception, and hepatoprotection, respectively, of the combined therapy and implicate provoked cross talk by nicorandil and morphine on opioid receptors and cGMP signaling pathway. That said, nicorandil/morphine combination provides a potential multitargeted therapy to alleviate pain and preserve liver function.

Abstract
The objective of the present study was to scrutinize the effect of nitric oxide (NO), cGMP, potassium channel blockers and metformin on the citral-produced peripheral antinociception. The rat paw 1% formalin test was used to assess nociception and antinociception. Rats were treated with local peripheral administration of citral (10-100 µg/paw). The antinociception of citral (100 µg/paw) was evaluated with and without the local pretreatment of naloxone, NG-L-nitro-arginine methyl ester (L-NAME, a NO synthesis inhibitor), 1H-(1,2,4)-oxadiazolo(4,2-a)quinoxalin-1-one (ODQ, a soluble guanylyl cyclase inhibitor), metformin, opioid receptors antagonists, and K+ channel blockers. Injection of citral in the rat paw significantly decreased the nociceptive effect of formalin administration during the two phases of the test. Local pretreatment of the paws with L-NAME and ODQ did not reduced the citral-induced antinociception. Glipizide or glibenclamide (Kir6.1-2; ATP-sensitive K+ channel blockers), tetraethylammonium or 4-aminopyridine (KV; voltage-gated K+ channel blockers) or charybdotoxin (KCa1.1; big conductance calcium-activated K+ channel blocker) or apamin (KCa2.1-3; small conductance Ca2+-activated K+ channel antagonist), or metformin, but not the opioid antagonists, reduced the antinociception of citral. Citral produced peripheral antinociception during both phases of the formalin test. These effects were due to the activation of K+ channels and a biguanide-dependent mechanism.

Abstract
As a promising flavonoid, naringenin has shown potential anti-inflammatory and antioxidant properties mainly in inflammatory pain models by oral administration. Therefore, we investigated the antinociceptive activity of this compound by intraperitoneally (i.p.) administration, as well as, associated mechanism of action considering the involvement of L-arginine/nitric oxide (NO)/cyclic GMP (cGMP)/potassium channel (KATP) pathway and opioid receptors. The antinociceptive effect of naringenin was evaluated in male NMRI mice using formalin test at early and late phases. To assess the involvement of L-arginine/NO/cGMP/KATP pathway and opioid receptors, mice were pretreated i.p. with L-arginine (NO precursor), S-nitroso-N-acetylpenicillamine (SNAP, NO donor), N(gamma)-nitro-L-arginine methyl ester (L-NAME, inhibitor of nitric oxide synthase), sildenafil (inhibitor of phosphodiesterase enzyme), glibenclamide (KATP channel blocker) and naloxone (an opioid receptor antagonist), respectively 20 min before administration of the most effective dose of naringenin. Naringenin showed a dose-dependent antinociceptive effect at both early and late phases of the formalin test. The dose of 100 mg/kg of naringenin was identified as the most effective dose and selected for further experiments. Our mechanistic evaluations showed that L-arginine, SNAP and sildenafil could enhance the antinociceptive effects of naringenin, revealing the critical role of NO and cGMP during its antinociceptive effect. On the other hand, glibenclamide and naloxone could mitigate the antinociceptive potential of naringenin at both phases of formalin test, which confirmed the associated role of KATP channels and opioid receptors. In conclusion, naringenin could be a promising antinociceptive agent acting through opioid receptors and L-arginine/NO/cGMP/KATP channel pathway.

Abstract
OBJECTIVE The leukotrienes are inflammatory mediators. In the present study, the analgesic role of local montelukast, a cysteinyl leukotriene receptor antagonist, and the possible involvement of L-arginine/NO/cGMP/KATP channel pathway and PPARγ receptors was assessed in the formalin test in rats. METHODS AND RESULTS The local administration of montelukast into the hind paw produced dose-related analgesia during both phases of the formalin test. Furthermore, pre-treatment with L-NAME, methylene blue, and glibenclamide prevented montelukast (10 μg/paw)-induced antinociception in both early and late phases of the test. Moreover, the local L-arginine and diazoxide before the sub-effective dose of montelukast (3 μg/paw) produced an analgesic effect. Also, local GW-9662 blocked antinociception induced by montelukast plus pioglitazone (10 μg/paw). CONCLUSION In conclusion, montelukast produced peripheral analgesia through PPARγ receptors and activation of the L-arginine/NO/cGMP/KATP channel pathway, with potential for a new topical analgesic drug.

Abstract
Pain is one of the most common medical challenges, reducing life quality. Despite the progression in pain management, it has remained a clinical challenge, which raises the need for investigating novel antinociceptive drugs with correspondence signaling pathways. Besides, the precise antinociceptive mechanisms of melatonin are not revealed. Accordingly, owing to the critical role of L-arginine/nitric oxide (NO)/cyclic GMP (cGMP)/KATP in the antinociceptive responses of various analgesics, the role of this signaling pathway is evaluated in the antinociceptive effects of melatonin. Male NMRI mice were intraperitoneally pretreated with the injection of L-arginine (NO precursor, 100 mg/kg), N(gamma)-nitro-L-arginine methyl ester [L-NAME, NO synthase (NOS) inhibitor, 30 mg/kg], S-nitroso-N-acetylpenicillamine (SNAP, NO donor, 1 mg/kg), sildenafil (phosphodiesterase inhibitor, 0.5 mg/kg), and glibenclamide (KATP channel blocker, 10 mg/kg) alone and before the administration of the most effective dose of melatonin amongst the intraperitoneal doses of 50, 100, and 150 mg/kg. The formalin test (2%, 25 µL, intra-plantarly) was done following the melatonin administration, then the nociceptive responses of mice were evaluated during the early phase for 5 min and the late phase for 15 min. The results showed that 100 mg/kg dose of melatonin carried out the most antinociceptive effects. While the antinociceptive effect of melatonin was increased by L-arginine, SNAP, and sildenafil, it was significantly reduced by L-NAME and glibenclamide in both phases of the formalin test, with no relation to the sedative effects of melatonin evaluated by the inclined plane test. In conclusion, the antinociceptive effect of melatonin is mediated through the L-arginine/NO/cGMP/KATP pathway.

Abstract
The aim of this study was to examine if the peripheral antinociception of α-bisabolol involves the participation of nitric oxide (NO) and cyclic guanosine monophosphate (cGMP) synthesis followed by K+ channel opening in the formalin test. Wistar rats were injected in the dorsal surface of the right hind paw with formalin (1%). Rats received a subcutaneous injection into the dorsal surface of the paw of vehicles or increasing doses of α-bisabolol (100-300 µg/paw). To determine whether the peripheral antinociception induced by α-bisabolol was mediated by either the opioid receptors or the NO-cGMP-K+ channels pathway, the effect of pretreatment (10 min before formalin injection) with the appropriate vehicles, naloxone, naltrexone, NG-nitro-l-arginine methyl ester (L-NAME), 1H-[1,2,4]-oxadiazolo[4,2-a]quinoxalin-1-one (ODQ), glibenclamide, glipizide, apamin, charybdotoxin, tetraethylammonium, or 4-aminopyridine on the antinociceptive effects induced by local peripheral α-bisabolol (300 µg/paw) were assessed. α-Bisabolol produced antinociception during both phases of the formalin test. α-Bisabolol antinociception was blocked by L-NAME, ODQ, and all the K+ channels blockers. The peripheral antinociceptive effect produced by α-bisabolol was not blocked by the opioid receptor inhibitors. α-Bisabolol was able to active the NO-cGMP-K+ channels pathway to produce its antinoceptive effect. The participation of opioid receptors in the peripheral local antinociception induced by α-bisabolol is excluded.

Abstract
Carbamazepine, an anticonvulsant drug, has shown antidepressant effects in clinical and experimental models. Nitric oxide (NO) is a neurotransmitter in the central nervous system and has been involved in a variety of diseases including depression. In the present study, the involvement of NO/cyclic GMP/KATP channels pathway in the antidepressant action of carbamazepine was investigated in mice. The antidepressant-like activity was assessed in the forced swim test (FST) behavioral paradigm. Carbamazepine reduced (40 mg/kg, intraperitoneal) immobility period. The antidepressant-like effect of carbamazepine (40 mg/kg, intraperitoneal) was prevented by pretreatment with L-arginine [substrate for NO synthase (NOS), 750 mg/kg, intraperitoneal], sildenafil (a PDE-5 inhibitor, 5 mg/kg, intraperitoneal) and diazoxide (K+ channels opener, 10 mg/kg). Pretreatment of mice with L-NAME (a non-selective NOS inhibitor, 10 mg/kg, intraperitoneal), methylene blue (direct inhibitor of both NOS and soluble guanylate cyclase, 10 mg/kg, intraperitoneal) and glibenclamide (an ATP-sensitive K+ channel blocker, 1 mg/kg, intraperitoneal) produced potentiation of the action of a sub-effective dose of carbamazepine (30 mg/kg, intraperitoneal). Also, carbamazepine (30 mg/kg) potentiated the antidepressant-like effect of fluoxetine through NO modulation. The various modulators used in the study did not produce any changes in locomotor activity per se. The results demonstrated that the antidepressant-like effect of carbamazepine in the FST involved an interaction with the NO/cGMP/KATP channels pathway.

Abstract
Pain is the most common sensation installed in us naturally which plays a vital role in defending us against severe harm. This neurological mechanism pathway has been one of the most complex and comprehensive topics but there has never been an elaborate justification of the types of analgesics that used to reduce the pain sensation through which specific pathways. Of course, there have been some answers to curbing of pain which is a lifesaver in numerous situations-chronic and acute pain conditions alike. This has been explored by scientists using pain-like behavioral study methodologies in non-anesthetized animals since decades ago to characterize the analgesic profile such as centrally or peripherally acting drugs and allowing for the development of analgesics. However, widely the methodology is being practiced such as the tail flick/Hargreaves test and Von Frey/Randall-Selitto tests which are stimulus-evoked nociception studies, and there has rarely been a complete review of all these methodologies, their benefits and its downside coupled with the mechanism of the action that is involved. Thus, this review solely focused on the complete protocol that is being adapted in each behavioral study methods induced by different phlogogenic agents, the different assessment methods used for phasic, tonic and inflammatory pain studies and the proposed mechanism of action underlying each behavioral study methodology for analgesic drug profiling. It is our belief that this review could significantly provide a concise idea and improve our scientists' understanding towards pain management in future research.

Abstract
Simvastatin, one of the lipophilic statins, has been shown to be effective in reducing depression in rodents. The present study aimed to investigate the potential antidepressant-like activity of simvastatin and the possible involvement of NO-cGMP-KATP channels pathway and PPARγ using forced swimming test (FST) in mice. In addition, the interaction between simvastatin and fluoxetine as a reference drug was examined. After assessment of locomotor behavior in the open-field test (OFT), FST was applied for evaluation of depressive behavior in mice. Simvastatin at doses (20, 30, and 40 mg/kg, i.p.) was administrated 30 min before the OFT or FST. To evaluate the involvement of NO-cGMP-KATP channels pathway, mice were pre-treated intraperitoneally with l-arginine (a nitric oxide precursor, 750 mg/kg), L-NAME (a NOS inhibitor, 10 mg/kg), methylene blue (guanylyl cyclase inhibitor, 20 mg/kg), sildenafil (a PDE-5 inhibitor, 5 mg/kg), glibenclamide (ATP-sensitive K+ channel blocker, 1 mg/kg), and diazoxide (K+ channels opener, 10 mg/kg). Moreover, to clarify the probable involvement of PPARγ receptors, pioglitazone, a PPARγ agonist (5 mg/kg, i.p.), and GW9662, a PPARγ antagonist (2 mg/kg, i.p.), were pre-treated with simvastatin. Immobility time was significantly decreased after simvastatin injection. Administration of L-NAME, methylene blue, glibenclamide and pioglitazone in combination with the sub-effective dose of simvastatin (20 mg/kg, i.p.) reduced the immobility time in the FST compared to drugs alone, while co-administration of effective doses of simvastatin (30 mg/kg, i.p.) with l-arginine, sildenafil, diazoxide, and GW9662 prevented the antidepressant-like effect of simvastatin. In addition, simvastatin (20 mg/kg) potentiated the antidepressant-like effect of fluoxetine through the NO pathway. None of the drugs produced any significant alterations in locomotor activity using OFT. These results demonstrated that NO-cGMP-KATP channels pathway and PPARγ receptors may be involved in the antidepressant-like effect of simvastatin.

Abstract
Here, we aimed to investigate the effects of fluoxetine on morphine-induced analgesia, as well as preventive effects of it on morphine induced tolerance and dependence in mice. We also elucidate the involvement of L-type Ca2+ channels in these phenomena. To induce morphine tolerance, mice were treated with morphine (50 mg/kg) for 3 consecutive days. To evaluate the involvement of the calcium channel in the effects of fluoxetine (5, 20 mg/kg), combination ineffective doses of the two L-type calcium channel blockers, nimodipine (5 mg/kg) or diltiazem (20 mg/kg) with flouxetine were used with each morphine dose. Nociceptive behavior was evaluated using hot-plate test, while physical dependence assessed by naloxone-precipitated withdrawal on the fourth day of experiment. The expression of Cav1.2 and Cav1.3 subunits of the L-type calcium channels in cortex and mesolimbic tissues were measured using western immunoassay. Results showed that co-administration of fluoxetine (20 mg/kg) with morphine increased its acute analgesia effect and prevented the induction of morphine antinociceptive tolerance and physical dependence in mice. Moreover, these effects was potentiated by pre-treatment with diltiazem or nimodipine. Results also showed up-regulation of the Cav1.3 and Cav1.2 expression in the cerebral cortex and mesolimbic regions through the development of morphine dependence. Moreover, chronic administration of fluoxetine with morphine reduced the observed up-regulation of Cav1.3 and Cav1.2 expression in cortex and mesolimbic tissues. Our data indicated that co-administering of fluoxetine with morphine could potentiate the antinociceptive effect of morphine, prevent morphine analgesia tolerance and attenuated the morphine withdrawal signs during induction phases. Moreover, we also pointed out for the first time the role of L-type Ca2+ channel channels in the modulatory effects of fluoxetine on the morphine-related effects.

Abstract
Appropriate treatment of pain requires analgesics and anti-inflammatory drugs generally associated with undesirable side effects and not fully effective in a significant proportion of patients. Organoselenium compounds elicit a plenty of pharmacological effects in different animal models. Among these compounds, the 2,2`-dipyridyl diselenide (DPD) has a potent antioxidant effect and low toxicity. In this way, the aim of this study was to investigate the possible DPD antinociceptive effect and its mechanism of action, as well as the safety of the compound. Female Swiss mice were treated with vehicle or DPD (0.01-50 mg/kg) intragastrically. Dose-response curve and time-course of the antinociceptive effect of DPD were performed on formalin and tail immersion tests. Morphine (2.5 mg/kg, subcutaneous, 15 min earlier) was used as a positive control in behavioral tests. The results showed that DPD presents a rapid antinociceptive effect in low doses, without changing the spontaneous locomotor activity and parameters of toxicity in mice. The DPD antinociceptive effect was also confirmed in male Swiss mice in both formalin and tail immersion tests. In addition, DPD reduced the paw edema induced by 2.5% formalin and ear edema induced by 2.5% croton oil. l-arginine (600 mg/kg, intraperitoneally) reduced the DPD antinociceptive effect in the first phase of the formalin test. Moreover, DPD attenuated the increase in iNOS, NF-κB and JNK phosphorylation in the spinal cord of mice injected with formalin. These results showed that DPD exerts peripheral and central nociceptive actions associated with anti-inflammatory effect and this organoselenium compound could be an interesting alternative therapy for pain treatment.
