Electroencephalographic profile of Salvia amarissima Ortega and amarisolide A in the absence and presence of PTZ-induced seizures in mice. Biomed Pharmacother 2024; 173:116352. [PMID: 38417289 DOI: 10.1016/j.biopha.2024.116352] [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: 12/19/2023] [Revised: 02/19/2024] [Accepted: 02/24/2024] [Indexed: 03/01/2024] Open
Abstract
Salvia amarissima Ortega is a plant used in traditional medicine to treat CNS's affections. Despite its depressant properties in anxiety and fibromyalgia, there is no scientific evidence about its capability to control seizure activity. This study aimed to investigate the effects of the S. amarissima aqueous extract (SAAE) and its metabolite amarisolide A (AMA) on the electrocorticographic (ECoG) activity. The ECoG profiles were previously and concurrently analyzed to the pentylenetetrazole (85 mg/kg, i.p.)-induced seizure behavior after thirty min of the administration of several doses of the SAAE (1, 10, 30, and 100 mg/kg, i.p.) and two doses of AMA (0.5 and 1 mg/kg, i.p.). A dosage of AMA (1 mg/kg,i.p.) was selected to explore a possible mechanism of action by using antagonists of inhibitory receptors such as GABAA (picrotoxin, 1 mg/kg, i.p.) or 5-HT1A of serotonin (WAY100635, 1 mg/kg, i.p.). Significant changes in the frequency bands and the spectral power were observed after the treatment alone. Additionally, SAAE and AMA produced significant and dose-dependent anticonvulsant effects by reducing the incidence and severity of seizures and increasing latency or survival. Both antagonists prevented the effects of AMA in the severity score of seizures and survival during the tonic-clonic seizures. In conclusion, our preclinical data support that S. amarissima possesses anticonvulsant properties, in part due to the presence of amarisolide A, mediated by different inhibitory mechanisms of action. Our scientific evidence suggests that this Salvia species and amarisolide A are potential neuroprotective alternatives to control seizures in epilepsy therapy.

Antihyperalgesic and Antiallodynic Effects of Amarisolide A and Salvia amarissima Ortega in Experimental Fibromyalgia-Type Pain. Metabolites 2022; 13:metabo13010059. [PMID: 36676984 PMCID: PMC9863681 DOI: 10.3390/metabo13010059] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/26/2022] [Revised: 12/21/2022] [Accepted: 12/23/2022] [Indexed: 01/03/2023] Open
Abstract
Salvia amarissima Ortega is an endemic species of Mexico used in folk medicine to alleviate pain and as a nervous tranquilizer. The S. amarissima extract and one of its abundant metabolites, identified and isolated through chromatographic techniques, were investigated to obtain scientific evidence of its potential effects to relieve nociplastic pain such as fibromyalgia. Then, the extract and amarisolide A (3-300 mg/kg, i.p.) were pharmacologically evaluated in reserpine-induced fibromyalgia-type chronic pain and in depressive-like behavior (as a common comorbidity) by using the forced swimming test in rats. The 5-HT1A serotonin receptor (selective antagonist WAY100635, 1 mg/kg, i.p.) was explored after the prediction of a chemical interaction using in silico analysis to look for a possible mechanism of action of amarisolide A. Both the extract and amarisolide A produced significant and dose-dependent antihyperalgesic and antiallodynic effects in rats, as well as significant antidepressive behavior without sedative effects when the antinociceptive dosages were used. The 5-HT1A serotonin receptor participation was predicted by the in silico descriptors and was corroborated in the presence of WAY100635. In conclusion, S. amarissima possesses antihyperalgesic, antiallodynic, and anti-depressive activities, partially due to the presence of amarisolide A, which involves the 5-HT1A serotonin receptor. This pharmacological evidence suggests that S. amarissima and amarisolide A are both potential alternatives to relieve pain-like fibromyalgia.

A Review on the Ethnopharmacology and Phytochemistry of the Neotropical Sages ( Salvia Subgenus Calosphace; Lamiaceae) Emphasizing Mexican Species. Front Pharmacol 2022; 13:867892. [PMID: 35517814 PMCID: PMC9061990 DOI: 10.3389/fphar.2022.867892] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2022] [Accepted: 03/28/2022] [Indexed: 11/13/2022] Open
Abstract
Salvia is the most diverse genus within the mint family (Lamiaceae), many of its species are well-known due to their medicinal and culinary uses. Most of the ethnopharmacological and phytochemical studies on Salvia are centred on species from the European and Asian clades. However, studies about the most diverse clade, the Neotropical sages (Salvia subgenus Calosphace; 587 spp.), are relatively scarce. This review aims to compile the information on the traditional medicinal uses, pharmacological and phytochemistry properties of the Neotropical sages. To do so, we carried out a comprehensive review of the articles available in different online databases published from the past to 2022 (i.e., PubMed, Scopus, and Web of Science, among others) and summarized the information in tables. To uncover phylogenetic patterns in the distribution of four different groups of metabolites (mono-, sesqui-, di-, and triterpenes), we generated presence-absence matrices and plotted the tip states over a dated phylogeny of Salvia. We found several studies involving Mexican species of Salvia, but only a few about taxa from other diversity centres. The main traditional uses of the Mexican species of Calosphace are medicinal and ceremonial. In traditional medicine 56 species are used to treat diseases from 17 categories according to the WHO, plus cultural-bound syndromes. Pharmacological studies reveal a wide range of biological properties (e.g., antinociceptive, anti-inflammatory, anxiolytic, cytotoxic, and antidiabetic, etc.) found in extracts and isolated compounds of 38 Neotropical sages. From extracts of these species, at least 109 compounds have been isolated, identified and evaluated pharmacologically; 73 of these compounds are clerodanes, 21 abietanes, six flavonoids, five sesquiterpenoids, and four triterpenoids. The most characteristic metabolites found in the Neotropical sages are the diterpenes, particularly clerodanes (e.g., Amarisolide A, Tilifodiolide), that are found almost exclusively in this group. The Neotropical sages are a promising resource in the production of herbal medication, but studies that corroborate the properties that have been attributed to them in traditional medicine are scarce. Research of these metabolites guided by the phylogenies is recommended, since closely related species tend to share the presence of similar compounds and thus similar medicinal properties.

Abstract
Chemotherapy-induced neuropathic pain is a common side effect for cancer patients which has limited effective treatment options. Kappa opioid receptor (KOR) agonists are a promising alternative to currently available opioid drugs due to their low abuse potential. In the current study, we have investigated the effects of Salvinorin A (SalA) analogues, 16-Ethynyl SalA, 16-Bromo SalA and ethyoxymethyl ether (EOM) SalB, and in a preclinical model of paclitaxel-induced neuropathic pain in male and female C57BL/6J mice. Using an acute dose-response procedure, we showed that compared to morphine, 16-Ethynyl SalA was more potent at reducing mechanical allodynia; and SalA, 16-Ethynyl SalA, and EOM SalB were more potent at reducing cold allodynia. In the mechanical allodynia testing, U50,488 was more potent in males and SalA was more potent in females. There were no sex differences in the acute cold allodynia testing. In the chronic administration model, treatment with U50,488 (10 mg/kg) reduced the mechanical and cold allodynia responses to healthy levels over 23 days of treatment. Overall, we have shown that KOR agonists are effective in a model of chemotherapy-induced neuropathic pain, indicating that KOR agonists could be further developed to treat this debilitating condition.

Lamiaceae in Mexican Species, a Great but Scarcely Explored Source of Secondary Metabolites with Potential Pharmacological Effects in Pain Relief. Molecules 2021; 26:7632. [PMID: 34946714 PMCID: PMC8705283 DOI: 10.3390/molecules26247632] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/20/2021] [Revised: 12/05/2021] [Accepted: 12/09/2021] [Indexed: 02/07/2023] Open
Abstract
The search for molecules that contribute to the relief of pain is a field of research in constant development. Lamiaceae is one of the most recognized families world-wide for its use in traditional medicine to treat diseases that include pain and inflammation. Mexico can be considered one of the most important centers of diversification, and due to the high endemism of this family, it is crucial for the in situ conservation of this family. Information about the most common genera and species found in this country and their uses in folk medicine are scarcely reported in the literature. After an extensive inspection in bibliographic databases, mainly Sciencedirect, Pubmed and Springer, almost 1200 articles describing aspects of Lamiaceae were found; however, 217 articles were selected because they recognize the Mexican genera and species with antinociceptive and/or anti-inflammatory potential to relieve pain, such as Salvia and Agastache. The bioactive constituents of these genera were mainly terpenes (volatile and non-volatile) and phenolic compounds such as flavonoids (glycosides and aglycone). The aim of this review is to analyze important aspects of Mexican genera of Lamiaceae, scarcely explored as a potential source of secondary metabolites responsible for the analgesic and anti-inflammatory properties of these species. In addition, we point out the possible mechanisms of action involved and the modulatory pathways investigated in different experimental models. As a result of this review, it is important to mention that scarce information has been reported regarding species of this family from Mexican genera. In fact, despite Calosphace being one of the largest subgenera of Salvia in the world, found mainly in Mexico, it has been barely investigated regarding its potential biological activities and recognized bioactive constituents. The scientific evidence regarding the different bioactive constituents found in species of Lamiaceae demonstrates that several species require further investigation in preclinical studies, and of course also in controlled clinical trials evaluating the efficacy and safety of these natural products to support their therapeutic potential in pain relief and/or inflammation, among other health conditions. Since Mexico is one of the most important centers of diversification, and due to the high endemism of species of this family, it is crucial their rescue, in situ conservation, and investigation of their health benefits.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Salvia chudaei Batt. & Trab. from Algeria is traditionally used to relieve several dysfunctions, including inflammatory and pain-related situations. AIM OF THE STUDY This work aimed to confirm scientifically the referred properties. For that, the phenolic composition and antioxidant activity were evaluated as well as acute toxicity, anti-inflammatory and analgesic effects of different doses of the infusion of S. chudaei aerial parts. MATERIALS AND METHODS Infusion of aerial parts of S. chudaei was prepared and screened for phenolic composition by generalized methods TPC and TFC then by LC-DAD-ESI/MSn. DPPH and FRAP were used to evaluate antioxidant activity. Using mice, acute toxicity, anti-inflammatory by carrageenan-induced paw edema, and analgesic by acetic acid-induced writhing and formalin-induced pain activities were tested. RESULTS The infusion showed 2018 mg GAE/100g DW of phenolics and 1956 mg ECE/100g DW of flavonoids. Phenolic profile by LC-DAD-ESI/MSn revealed the presence of ten compounds: syringic acid hexoside derivative, kaempferol-O-diglucuronide, kaempferol-O-deoxyhexoside-hexoside, kaempferol-O-glucuronide, apigenin-O-diglucuronide, caffeic acid, 4-O-caffeoylquinic acid, eriodictyol-O-glucuronide, rosmarinic acid hexoside, and rosmarinic acid. This acid was the major compound representing 54% of the total content of the identified compounds and an absolute content of 18 mg/g of extract. Additionally, the infusion exhibited a good antioxidant activity (DPPH: 81 μmol TE/g DW, FRAP: 438 μmol FSE/g DW). By oral administration to mice, the infusion showed a significant (p<0.05) dose-dependent reduction of carrageenan-induced inflammation and inhibition of formalin-induced pain (late and early phase) and acetic acid-induced writhing compared with the control. On the other hand, infusion up to 8 g/kg b.w. showed no signs of toxicity or mortality. CONCLUSION This study reveals, for the first time, that the infusion of the aerial parts of S. chudaei is not toxic in a single dose and has remarkable antioxidant, anti-inflammatory, and analgesic activities, supporting the use of this species in folk medicine.

Abstract
Despite the availability of many anti-pain drugs, in the form of NSAIDs, steroids, gabapentinoids, opioids, and antidepressants, in this study we address the natural compounds belonging to the group of Mexican medicinal plants or "Mexican folk medicine", used for pain management in Mexico. Our interest in this subject is due to the growing idea that "natural is harmless" and to the large number of side effects exhibited in pharmacotherapy. The objective of this review was to document the scientific evidence about Mexican medicinal plants and their derivatives used for inflammatory and neuropathic pain treatment, as well as the mechanisms of action implicated in their antinociceptive effects, their possible adverse effects, and the main pharmacological aspects of each plant or compound. Our data review suggested that most studies on Mexican medicinal plants have used inflammatory experimental models for testing. The anti-pain properties exerted by medicinal plants lack adverse effects, and their toxicological assays report that they are safe to consume; therefore, more studies should be performed on preclinical neuropathic pain models. Moreover, there is no convincing evidence about the possible mechanisms of action involved in the anti-pain properties exerted by Mexican plants. Therefore, the isolation and pharmacological characterization of these plant derivatives' compounds will be important in the design of future preclinical studies.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Mexico is considered an ancestral center of diversity of Salvia species, however many of them lack scientific information. Salvia circinnata Cav. (syn. Salvia amarissima Ortega) is an endemic species used in traditional medicine to treat disorders attributed to a cold state like anxiety in the central nervous system, as well as gastrointestinal ailments and pain relief. AIM OF THE STUDY To give preclinical evidence about the pharmacological properties of this species by investigating its antinociceptive and anti-inflammatory effects, the chemical nature of at least one metabolite, and a possible mechanism of action and adverse effects, using different experimental models of pain. MATERIAL AND METHODS Different crude extracts of Salvia circinnata Cav. aerial parts were prepared using increasing polarity and evaluated in the formalin test in mice. This screening allowed to select and evaluate an ethyl acetate extract (EtOAc), as the most bioactive extract, and a metabolite. Antinociceptive and anti-inflammatory activities were confirmed using the plantar test and carrageenan-induced edema. The antinociceptive effects of the extracts were compared to that observed with morphine (1 mg/kg), tramadol (20 mg/kg) or indomethacin (20 mg/kg) as reference drugs. Participation of opioids and TRPV1 receptors was investigated, as well as acute toxicity and adverse effects of sedation and gastric damage. RESULTS EtOAc (0.1-10 mg/kg) of S. circinnata Cav. showed a dose-dependent and significant antinociceptive activity, associated in part with the presence of a neo-clerodane glycoside amarisolide A (0.01-1 mg/kg), in the neurogenic and inflammatory phases of the formalin test. Central action of both treatments was corroborated in the plantar test, whereas anti-inflammatory effects were confirmed with the extract (1 and 10 mg/kg) and amarisolide A (1 mg/kg) in the carrageenan-induced edema test. An opioid mechanism in both treatments, and the TRPV1 receptor modulation in the extract were involved. No acute toxicity and adverse effects were noticed with the extract and pure compound in comparison to the reference drugs. CONCLUSION These results provide preclinical evidence of the ethnopharmacological antinociceptive S. circinnata Cav. properties, in which the neo-clerodane diterpene glycoside amarisolide A was partially responsible involving the participation of the opioid receptors, while TRPV1 receptor modulation was implicated in the anti-inflammatory activity may be because of the presence of other constituents. This information supports the use of this species in folk medicine for pain therapy.

Pharmacokinetics and Pharmacodynamics of Salvinorin A and Salvia divinorum: Clinical and Forensic Aspects. Pharmaceuticals (Basel) 2021; 14:ph14020116. [PMID: 33546518 PMCID: PMC7913753 DOI: 10.3390/ph14020116] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/31/2020] [Revised: 01/26/2021] [Accepted: 01/29/2021] [Indexed: 01/13/2023] Open
Abstract
Salvia divinorum Epling and Játiva is a perennial mint from the Lamiaceae family, endemic to Mexico, predominantly from the state of Oaxaca. Due to its psychoactive properties, S. divinorum had been used for centuries by Mazatecans for divinatory, religious, and medicinal purposes. In recent years, its use for recreational purposes, especially among adolescents and young adults, has progressively increased. The main bioactive compound underlying the hallucinogenic effects, salvinorin A, is a non-nitrogenous diterpenoid with high affinity and selectivity for the κ-opioid receptor. The aim of this work is to comprehensively review and discuss the toxicokinetics and toxicodynamics of S. divinorum and salvinorin A, highlighting their psychological, physiological, and toxic effects. Potential therapeutic applications and forensic aspects are also covered in this review. The leaves of S. divinorum can be chewed, drunk as an infusion, smoked, or vaporised. Absorption of salvinorin A occurs through the oral mucosa or the respiratory tract, being rapidly broken down in the gastrointestinal system to its major inactive metabolite, salvinorin B, when swallowed. Salvinorin A is rapidly distributed, with accumulation in the brain, and quickly eliminated. Its pharmacokinetic parameters parallel well with the short-lived psychoactive and physiological effects. No reports on toxicity or serious adverse outcomes were found. A variety of therapeutic applications have been proposed for S. divinorum which includes the treatment of chronic pain, gastrointestinal and mood disorders, neurological diseases, and treatment of drug dependence. Notwithstanding, there is still limited knowledge regarding the pharmacology and toxicology features of S. divinorum and salvinorin A, and this is needed due to its widespread use. Additionally, the clinical acceptance of salvinorin A has been hampered, especially due to the psychotropic side effects and misuse, turning the scientific community to the development of analogues with better pharmacological profiles.

Antinociceptive effects of Salvia divinorum and bioactive salvinorins in experimental pain models in mice. JOURNAL OF ETHNOPHARMACOLOGY 2020; 248:112276. [PMID: 31593812 DOI: 10.1016/j.jep.2019.112276] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/12/2019] [Revised: 09/23/2019] [Accepted: 10/03/2019] [Indexed: 05/29/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Salvia divinorum Epling & Játiva is a Mexican plant used not only in rituals but also in traditional medicine for pain relief. One of the most known bioactive compounds is salvinorin A, which acts centrally in kappa-type opioid receptors. AIM OF THE STUDY Despite its traditional use as a medicinal plant, there is not enough scientific investigation to reinforce its potential as analgesic. In this study, Salvia divinorum antinociceptive activity was evaluated in experimental models of nociceptive pain; the writhing test and formalin-induced licking behavior in mice. MATERIAL AND METHODS Different Salvia divinorum extracts were prepared by maceration at room temperature in increased polarity (hexane, ethyl acetate and methanol). The ethyl acetate extract (EAEx) was chosen in order to be fractioned and to obtain a mixture of salvinorins. The antinociceptive effect of EAEx (3, 10, 30, and 100 mg/kg, i.p.) was compared with that of tramadol (a partial opioid agonist analgesic drug, 30 mg/kg, i.p.) and the mixture of salvinorins (30 mg/kg, i.p.). In addition, a participation of opioids (naloxone, NX 1 and/or 3 mg/kg, i.p.) and serotonin 5-HT1A receptors (WAY100635, 0.32 mg/kg, i.p.) was investigated as possible inhibitory neurotransmission involved. RESULTS As a result, the EAEx produced significant and dose-dependent antinociceptive effect concerning salvinorins constituents. This effect was blocked in the presence of NX and WAY100635 in the abdominal test, but only by NX in the formalin-induced licking behavior. Whereas, the effect of salvinorins mixture involved opioids and serotonin 5-HT1A receptors. CONCLUSION Data provide evidence of the potential of this species, where salvinorin A is in part responsible bioactive constituent involving participation of the opioids and/or 5-HT1A serotonin receptors depending on the kind of pain model explored.

Abstract
Neuropathic pain (NP) is an enormous burden for patients, caregivers and society. NP is a pain state that may develop after injury of the peripheral or central nervous system because of a wide range of diseases and traumas. A NP symptom component can be found also in several types of chronic pain. Many NP patients are substantially disabled for years. Due to its chronicity, severity and unpredictability, NP is difficult to treat. Tapentadol is a central-acting oral analgesic with combined opioid and noradrenergic properties, which make it potentially suitable for a wide range of pain conditions, particularly whenever a NP component is present or cannot be excluded. In randomized controlled trials, tapentadol has proved to be effective in relieving NP in diabetic peripheral neuropathy and in chronic low back pain. In observational studies, tapentadol reduced NP in chemotherapy-induced peripheral neuropathies, blood and solid cancers, and the NP component in neck pain and Parkinson's disease. This narrative review aims to provide clinicians with a broad overview of tapentadol effects on NP.

Abstract
Salvia divinorum is a herbal plant native to the southwest region of Mexico. Traditional preparations of this plant have been used in illness treatments that converge with inflammatory conditions and pain. Currently, S. divinorum extracts have become popular in several countries as a recreational drug due to its hallucinogenic effects. Its main active component is a diterpene named salvinorin A (SA), a potent naturally occurring hallucinogen with a great affinity to the κ opioid receptors and with allosteric modulation of cannabinoid type 1 receptors. Recent biochemical research has revealed the mechanism of action of the anti-inflammatory and analgesic effect of SA at the cellular and molecular level. Nevertheless, because of their short-lasting and hallucinogenic effect, the research has focused on discovering a new analogue of SA that is able to induce analgesia and reduce inflammation with a long-lasting effect but without the hallucinatory component. In this review, we explore the role of S. divinorum, SA and its analogues. We focus mainly on their analgesic and anti-inflammatory roles but also mention their psychoactive properties.

Abstract
BACKGROUND Neuropathic pain is one of the most important challenges in public health. The search for novel treatments is important for an adequate relief without adverse effects. In this sense salvinorin A (SA), the main diterpene of the medicinal plant Salvia divinorum is an important antinociceptive compound, which acts as a potent agonist of kappa opioid receptor (KOR) and cannabinoid CB1 receptors. METHODS We evaluated nociceptive responses in a neuropathic pain model induced by the sciatic nerve ligature (SNL) in the right hind paw, after the microinjection of SA, Salvinorin B (SB), KOR and CB1 antagonists directly in the insular cortex (IC) in male wistar rats. RESULTS We found a potent antinociceptive effect with the administration of SA. Moreover, this effect was blocked by the administration of a KOR antagonist as well as the administration of a CB1 antagonist. CONCLUSION Salvinorin A has a potent antinociceptive effect when is administered centrally in the IC by the interaction with KOR and CB1 receptors. SIGNIFICANCE We show evidence on the effectiveness of the administration of salvinorin A in the IC in a rodent model of neuropathic pain. These results support the use of novel compounds like SA as a therapeutic alternative for neuropathic pain relief.
