Abstract
This work involves the synthesis and subsequent development of a number of novel organocatalysts generated from β-amino acids bearing diendo and diexo norbornene skeletons to improve their catalytic characteristics. The aldol reaction between isatin and acetone selected as the model reaction, was used to test and study enantioselectivities. The potential impact on enantioselectivity control regarding enantiomeric excess (ee%) was probed by varying the reaction parameters, such as additive, solvent, catalyst loading, temperature and substrate range. The corresponding 3-hydroxy-3-alkyl-2-oxindole derivetives were produced by organocatalyst 7 with good enantioselectivity up to 57% ee in the presence of LiOH. Substrate screening was used to investigate a number of substituted isatins with excellent findings up to 99% ee. Another aspect of this effort involved employing high-speed ball mill apparatus to conduct a mechanochemical study to make this model reaction more environmentally benign and sustainable.

Abstract
The present study was intended to explore the valuable effects of triptonide on inflammation, asthmatic, and nociceptive. Triptonide possesses numerous beneficial effects extensively managed in the treatment of inflammation disease condition. Initially, triptonide showed anti-inflammation properties over lipopolysaccharide-induced RAW 264.7 cells. Hence, the present study was directed to explore the protecting efficacy of triptonide in ovalbumin (OVA)-induced asthma in mice. Asthma was induced intraperitoneally administration (200μL) in female BALB/c mice with suspension which has ovalbumin (100 μg/mL) and aluminum hydroxide (10 mg/mL). Triptonide (30 mg/kg) over OVA-induced experimental animals altered lung mass, nitric oxide, myeloperoxidase, immunoglobulin E status, interleukins (4, 5, and 13) inflammatory cytokines status, and histological modifications. Animals were also managed with the standard drug dexamethasone (50 mg/kg) followed by the asthma induction, which is also efficient over OVA-induced experimental animals. The nociception was provoked in male Swiss mice by various chemicals (acetic acid, capsaicin, and glutamate). The animals were administered with triptonide (5, 10, and 15 mg/kg) and separate standard drugs like diclofenac sodium (10 mg/kg) and morphine (5 mg/kg) over chemical-induced nociceptive animals. The present outcome evidently established that the triptonide considerably reduced the various chemical-induced nociception in mice (Fig. 7A, B, and C). Ultimately, the present work explored the evident powerful anti-inflammation, antinociceptive, and anti-asthma properties of a diterpenoid, triptonide experimental animal models. And it is recommended that triptonide is an excellent compound in the management of asthma and its related diseases.

Abstract
A highly efficient catalytic asymmetric Rubottom-type oxidation is described. Using meta-chloroperbenzoic acid (m-CPBA) as the oxidant and chiral calcium phosphate as the catalyst, the facile transformation enables direct hydroxylation of N-Boc oxindoles and β-ketoesters in high yields (up to 99 %) and in a highly enantioenriched fashion (up to >99 % ee). The application of the established method was demonstrated by the synthesis of a pharmaceutically important 3-hydroxyoxindole with excellent enantiocontrol.

Abstract
BACKGROUND Despite the existence of a wide variety of anti-inflammatory drugs, the vast majority are classified as steroidal or non-steroidal. Both classes present a variety of side effects that limit usage. Thus, the search for new molecules with anti-inflammatory potential is still important. METHODS Five phenylbenzohydrazides were synthetized and evaluated in pre-clinical models of acute inflammation in vivo and in vitro. RESULTS The new substances (INL-06, -07, -10, and -11), as well as AISCT, significantly reduced cell migration induced by carrageenan. It was also observed that all INLs inhibited protein extravasation as well as cytokines (IL-6, IL-1β, and TNF-α) and nitric oxide (NO) production. The INL-11 was demonstrated to be the most potent, since the inhibition observed in several parameters was significant even when compared with dexamethasone. In vitro INLs also reduced cytokines and NO production and inducible nitric oxide (iNOS) enzyme activity. The INL-11 was the most effective in reducing cell migration in vitro. CONCLUSIONS Our data suggest that these substances are suitable for further development into a new series of compounds that could lead to new hits and future drug prototypes for anti-inflammatory conditions.

Abstract
The efficacy of µ-opioid receptors (MOR) in neuropathic pain is low and with numerous side effects that limited their use. Chronic neuropathic pain is also linked with emotional disorders that aggravate the sensation of pain and which treatment has not been resolved. This study investigates whether the administration of an oxindole, 5-fluoro-2-oxindole, could inhibit the nociceptive and emotional behaviors and increase the effectiveness of morphine via modulating the microglia and activating the nuclear factor erythroid-2 related factor 2 (Nrf2) signaling pathway and MOR expression. In C57BL/6 mice with neuropathic pain provoked by the total constriction of sciatic nerve we studied the effects of 10 mg/kg 5-fluoro-2-oxindole in: (i) the allodynia and hyperalgesia caused by the injury; (ii) the anxiety- and depressive-like behaviors; (iii) the local antinociceptive actions of morphine; (iv) the expression of CD11b/c (a microglial marker), the antioxidant and detoxificant enzymes Nrf2, heme oxygenase 1 (HO-1) and NAD(P)H:quinone oxidoreductase-1 (NQO1), and of MOR in the spinal cord and hippocampus. Results showed that the inhibition of the main nociceptive symptoms and the anxiety- and depressive-like behaviors induced by 5-fluoro-2-oxindole were accompanied with the suppression of microglial activation and the activation of Nrf2/HO-1/NQO1 signaling pathway in the spinal cord and/or hippocampus. This treatment also potentiated the pain-relieving activities of morphine by normalizing the reduced MOR expression. This work demonstrates the antinociceptive, anxiolytic and antidepressant effects of 5-fluoro-2-oxindole, suggests a new strategy to enhance the antinociceptive actions of morphine and proposes a new mechanism of action of oxindoles during chronic neuropathic pain.

Abstract
Several isatin derivatives have shown important biological activities, which have attracted interest from researchers. For this reason, the present study aimed to evaluate the anti-inflammatory and antinociceptive effects of the isatin derivative (Z)-2-(5-chloro-2-oxoindolin-3-ylidene)-N-phenyl-hydrazinecarbothioamide (COPHCT) in mice. Three doses of this compound were tested: 1.0, 2.5, and 5.0 mg/kg. The anti-inflammatory activity was assessed using the carrageenan-induced paw edema model and the zymosan-induced air pouch model. The evaluation of the antinociceptive effect was performed through the formalin test and the acetic acid-induced abdominal writhing test. The paw edema assay demonstrated that all doses of the compound showed a significant reduction of the edema in the second hour evaluated, but a better response was observed in the fourth hour. The zymosan-induced air pouch model indicated that the compound, in all doses, significantly reduced leukocyte migration and total protein concentration levels. In the formalin test, the doses 1.0, 2.5, and 5.0 mg/kg of COPHCT showed activity only in the second phase, with reduction in paw pain time of 73.61, 79.46, and 73.85%, respectively. The number of abdominal writhings decreased with the increasing dose, but only 5.0 mg/kg COPHCT exhibited a significant response, with a reduction of 24.88%. These results demonstrated the ability of this compound to interfere in the anti-inflammatory activity of edema, vascular permeability, and cell migration. In addition, its possible antinociceptive effect may be related to the dose used.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Capparis tomentosa Lam. root is one of the commonly used traditional medicines for the treatment of pain and inflammatory conditions by the Kunama ethnic group of Ethiopia. Yet, its ethnomedicinal claim has not been scientifically investigated. AIM OF THE STUDY This study aims to evaluate the anti-inflammatory and anti-nociception activities of root extracts of Capparis tomentosa Lam. MATERIALS AND METHODS The anti-inflammatory activity of the 70% ethanolic extracts and solvent fractions was determined using invitro hyaluronidase inhibition assay and in vivo carrageenan-induced paw edema in Swiss albino mice model. The anti-nociception effect was determined using the acetic acid-induced writhing model and tail immersion model in Swiss albino mice. RESULTS The root extract of Capparis tomentosa has exhibited significant hyaluronidase inhibition activity which was comparable with the reference drug, indomethacin. Significant inhibition of carrageenan-induced paw edema was observed in all the test sample treated mice compared to the negative control with the highest activity observed from butanol fraction which was equivalent to the effect of acetylsalicylic acid. All the root extract and solvent fractions have possessed a significant and dose-dependent abdominal writhing inhibition with the highest effect observed in the aqueous fraction. Additionally, the crude extract was found better in increasing the reaction latency of the mice to the hot water stimulus than the solvent fractions which were significant after 60-120 min compared to the distilled water treated group. The root extract and solvent fractions were also found safe at a single oral dose of 2 mg/g in Swiss albino mice. CONCLUSION The findings of the present study may partially support the folkloric use of Capparis tomentosa root for the treatment of pain and inflammation.

Abstract
Background: Stevia serrata Cav. (Asteraceae), widely found in Guatemala, is used to treat gastrointestinal problems. The aim of this study was to demonstrate the antinociceptive and anti-inflammatory effects of the essential oil (EO) and the mechanism of action. Methods: EO was tested in chemical (capsaicin- and glutamate-induced licking response) or thermal (hot plate) models of nociception at 10, 30 or 100 mg/kg doses. The mechanism of action was evaluated using two receptor antagonists (naloxone, atropine) and an enzyme inhibitor (L-NAME). The anti-hyperalgesic effect was evaluated using carrageenan-induced nociception and evaluated in the hot plate. Results: All three doses of EO reduced licking response induced by glutamate, and higher doses reduced capsaicin-induced licking. EO also increased area under the curve, similar to the morphine-treated group. The antinociceptive effect induced by EO was reversed by pretreatment of mice with naloxone (1 mg/kg, ip), atropine (1 mg/kg, ip) or L-NAME (3 mg/kg, ip). EO also demonstrated an anti-hyperalgesic effect. The 100 mg/kg dose increased the latency time, even at 1 h after oral administration and this effect has been maintained until the 96th hour, post-administration. Conclusions: Our data suggest that essential oil of S. serrata presents an antinociceptive effect mediated, at least in part, through activation of opioid, cholinergic and nitrergic pathways.

Antinociceptive, antiedematous, and antiallodynic activity of 1H-pyrrolo[3,4-c]pyridine-1,3(2H)-dione derivatives in experimental models of pain. Naunyn Schmiedebergs Arch Pharmacol 2019; 393:813-827. [PMID: 31858155 DOI: 10.1007/s00210-019-01783-3] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/17/2019] [Accepted: 11/28/2019] [Indexed: 12/25/2022]
Abstract
The aim of the presented study was to examine the potential antinociceptive, antiedematous (anti-inflammatory), and antiallodynic activities of two 1H-pyrrolo[3,4-c]pyridine-1,3(2H)-dione derivatives (DSZ 1 and DSZ 3) in various experimental models of pain. For this purpose, the hot plate test, the capsaicin test, the formalin test, the carrageenan model, and oxaliplatin-induced allodynia tests were performed. In the hot plate test, only DSZ 1 in the highest dose (20 mg/kg) was active but its effects appear to be due to sedatation rather than antinociceptiveness. In capsaicin-induced neurogenic pain model, both compounds displayed a significant antinociceptive activity. In the formalin test, DSZ 1 and DSZ 3 (5-20 mg/kg) revealed antinociceptive activity in both phases but it was more pronounced in the second phase of the test. In this test, pretreatment with caffeine, DPCPX reversed the antinociceptive effect of DSZ 3. On the other hand, pretreatment with L-NAME diminished the antinociceptive effect of DSZ 1. Pretreatment with naloxone did not affect antinociceptive activity of both compounds. Similar to ketoprofen, DSZ 1 and DSZ 3 showed antiedematous (antiinflammatory) and antihyperalgesic activity, and similar to lidocaine local anesthetic activity. Furthermore, both compounds (5 and 10 mg/kg) reduced tactile allodynia in acute and chronic phases of neuropathic pain. In the in vitro studies, DSZ 1 and DSZ 3 reduced the COX-2 level in LPS-activated RAW 264.7 cells, which suggests their anti-inflammatory activity. In conclusion, both DSZ 1 and DSZ 3 displayed broad spectrum of activity in several pain models, including neurogenic, tonic, inflammatory, and chemotherapy-induced peripheral neuropathic pain.

Abstract
Crataegus almaatensis, an endemic ornamental plant in Kazakhstan is used in popular medicine due to its cardiotonic properties. The most studied species of the same genus are commonly found in Europe, which shows the importance of having the Kazakh species validated via its chemical and pharmacological studies. High-speed countercurrent chromatography (HSCCC) operated under optimized conditions enabled an isolation of the three main compounds from the aqueous phase of the leaves ethanol extract, further identified by nuclear magnetic resonance (NMR), as quercetin 3-O-rhamnoside (quercitrin) (4.02% of the crude extract-CECa); quercetin 3-O-β-galactoside (hyperoside) (1.82% of CECa); kaempferol 3-O-α-L-rhamnoside (afzelin) (0.94% of CECa). The CECa, the aqueous phase of the crude extract (APCa) together with the isolates were evaluated for their vascular (vascular reactivity in human internal mammary artery-HIMA), anti-nociceptive (formalin-induced liking response and hot plate) and anti-inflammatory (subcutaneous air-pouch model-SAP) activities. CECa at the concentrations of 0.014 and 0.14 mg/mL significantly increased the maximum contractility response of HIMA to noradrenaline. The APCa CR curve (0.007–0.7 mg/mL) showed an intrinsic relaxation effect of the HIMA. APCa at the dose of 100 mg/kg i.p. significantly decreased the total leukocyte count and the IL-1β release in the SAP wash.

Abstract
5'-4-Alkyl/aryl-1H-1,2,3-triazole derivatives PILAB 1-12 were synthesized and a pharmacological screening of these derivatives was performed to identify a possible effect on the Central Nervous System (CNS) and to explore the associated mechanisms of action. The mice received a peritoneal injection (100 µmol/kg) of each of the 12 PILAB derivatives 10 min prior to the injection of pentobarbital and the mean hypnosis times were recorded. The mean hypnosis time increased for the mice treated with PILAB 8, which was prevented when mice were administered CTOP, a µ-opioid antagonist. Locomotor and motor activities were not affected by PILAB 8. The anxiolytic effect of PILAB 8 was evaluated next in an elevated-plus maze apparatus. PILAB 8 and midazolam increased a percentage of entries and spent time in the open arms of the apparatus compared with the control group. Conversely, a decrease in the percentages of entries and time spent in the closed arms were observed. Pretreatment with naloxone, a non-specific opioid antagonist, prior to administration of PILAB 8 exhibited a reverted anxiolytic effect. PILAB 8 exhibited antinociceptive activity in the hot plate test, and reduced reactivity to formalin in the neurogenic and the inflammatory phases. These data suggest that PILAB 8 can activate µ-opioid receptors to provoke antinociceptive and anti-inflammatory effects in mice.
