Anti-Inflammatory Effect of Izalpinin Derived from Chromolaena leivensis: λ-Carrageenan-Induced Paw Edema and In Silico Model. Molecules 2023; 28:molecules28093722. [PMID: 37175132 PMCID: PMC10179959 DOI: 10.3390/molecules28093722] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/30/2023] [Revised: 04/17/2023] [Accepted: 04/20/2023] [Indexed: 05/15/2023] Open
Abstract
The flavonoid izalpinin was isolated from the aerial parts of Chromolaena leivensis. Its structural determination was carried out using MS and NMR spectroscopic techniques (1H, 13C). This compound was evaluated for its anti-inflammatory effect in a rat model on λ-carrageenan-induced plantar edema. Paw inflammation was measured at one-hour intervals for seven hours following the administration of λ-carrageenan. Serum creatine kinase (CK) levels were evaluated, obtaining statistically significant results with the treatments at doses of 10 mg/kg (* p < 0.01) and 20 mg/kg (** p < 0.005). The anti-inflammatory effect of the compound was evaluated by using plethysmography, and the results showed significant differences at the three concentrations (10 mg/kg, 20 mg/kg, 40 mg/kg) in the first and third hours after treatment. * p < 0.05; ** p < 0.001; **** p < 0.0001 vs. the negative control group treated with vehicle (DMSO). Lastly, molecular docking analyses reveal that izalpinin has a strong binding affinity with five target proteins involved in the inflammatory process. The analysis using molecular dynamics allowed demonstrating that the ligand-protein complexes present acceptable stability, with RMSD values within the allowed range.

Bioactive Compounds from the Zingiberaceae Family with Known Antioxidant Activities for Possible Therapeutic Uses. Antioxidants (Basel) 2022; 11:antiox11071281. [PMID: 35883772 PMCID: PMC9311506 DOI: 10.3390/antiox11071281] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/04/2022] [Revised: 06/18/2022] [Accepted: 06/21/2022] [Indexed: 02/04/2023] Open
Abstract
The Zingiberaceae family is a rich source of diverse bioactive phytochemicals. It comprises about 52 genera and 1300 species of aromatic flowering perennial herbs with characteristic creeping horizontal or tuberous rhizomes. Notable members of this family include ginger (Zingiber officinale Roscoe), turmeric (Curcuma longa L.), Javanese ginger (Curcuma zanthorrhiza Roxb.), and Thai ginger (Alpinia galanga L.). This review focuses on two main classes of bioactive compounds: the gingerols (and their derivatives) and the curcuminoids. These compounds are known for their antioxidant activity against several maladies. We highlight the centrality of their antioxidant activities with notable biological activities, including anti-inflammatory, antidiabetic, hepatoprotective, neuroprotective, antimicrobial, and anticancer effects. We also outline various strategies that have been applied to enhance these activities and make suggestions for research areas that require attention.

Phytochemical study, molecular docking, genotoxicity and therapeutic efficacy of the aqueous extract of the stem bark of Ximenia americana L. in the treatment of experimental COPD in rats. JOURNAL OF ETHNOPHARMACOLOGY 2020; 247:112259. [PMID: 31577938 DOI: 10.1016/j.jep.2019.112259] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/08/2019] [Revised: 09/27/2019] [Accepted: 09/27/2019] [Indexed: 06/10/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Ximenia americana L. is popularly known as yellow plum, brave plum or tallow wood. All the parts of this plant are used in popular medicine. Its reddish and smooth bark are used to treat skin infections, inflammation of the mucous membranes and in the wound healing process. OBJECTIVE Verification of phytochemical profile, the molecular interaction between flavonoid, (-) epi-catechin and 5-LOX enzyme, by means of in silico study, the genotoxic effect and to investigate the pharmacological action of the aqueous extract of the stem bark of X. americana in pulmonary alterations caused by experimental COPD in Rattus norvegicus. MATERIALS AND METHODS The identification of secondary metabolites was carried out by TLC and HPLC chromatographic methods, molecular anchoring tests were applied to analyze the interaction of flavonoid present in the extract with the enzyme involved in pulmonary inflammation process and the genotoxic effect was assessed by comet assay and micronucleus test. For induction of COPD, male rats were distributed in seven groups. The control group was exposed only to ambient air and six were subjected to passive smoke inhalations for 20 min/day for 60 days. One of the groups exposed to cigarette smoke did not receive treatment. The others were treated by inhalation with beclomethasone dipropionate (400 mcg/kg) and aqueous and lyophilized extracts of X. americana (500 mg/kg) separately or in combination for a period of 15 days. The structural and inflammatory pulmonary alterations were evaluated by histological examination. Additional morphometric analyses were performed, including the alveolar diameter and the thickness of the right ventricle wall. RESULTS The results showed that the aqueous extract of the bark of X. americana possesses (-) epi -catechin, in silico studies with 5-LOX indicate that the EpiC ligand showed better affinity parameters than the AracA ligand, which is in accordance with the results obtained in vivo studies. Genotoxity was not observed at the dose tested and the extract was able to stagnate the alveolar enlargement caused by the destruction of the interalveolar septa, attenuation of mucus production and decrease the presence of collagen fibers in the bronchi of animals submitted to cigarette smoke. CONCLUSION Altogether, the results proved that the aqueous extract of X. americana presents itself as a new option of therapeutic approach in the treatment of COPD.
