Abstract
Chalcones are secondary metabolites belonging to the flavonoid (C6-C3-C6 system) family that are ubiquitous in edible and medicinal plants, and they are bioprecursors of plant flavonoids. Chalcones and their natural derivatives are important intermediates of the flavonoid biosynthetic pathway. Plants containing chalcones have been used in traditional medicines since antiquity. Chalcones are basically α,β-unsaturated ketones that exert great diversity in pharmacological activities such as antioxidant, anticancer, antimicrobial, antiviral, antitubercular, antiplasmodial, antileishmanial, immunosuppressive, anti-inflammatory, and so on. This review provides an insight into the chemistry, biosynthesis, and occurrence of chalcones from natural sources, particularly dietary and medicinal plants. Furthermore, the pharmacological, pharmacokinetics, and toxicological aspects of naturally occurring chalcone derivatives are also discussed herein. In view of having tremendous pharmacological potential, chalcone scaffolds/chalcone derivatives and bioflavonoids after subtle chemical modification could serve as a reliable platform for natural products-based drug discovery toward promising drug lead molecules/drug candidates.

Chalcone-rich extracts from Lonchocarpus cultratus roots present in vitro leishmanicidal and immunomodulatory activity. J Pharm Pharmacol 2021; 74:77-87. [PMID: 34791343 DOI: 10.1093/jpp/rgab155] [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: 05/18/2021] [Accepted: 10/19/2021] [Indexed: 11/13/2022]
Abstract
OBJECTIVES This study aimed to evaluate the in vitro anti-Leishmania activity of chalcone-rich three extracts (LDR, LHR and LMR) from Lonchocarpus cultratus (Vell.) A.M.G. Azevedo & H.C. Lima against L. amazonensis. Also, the immunomodulatory and antioxidant capacity was assessed. METHODS Successive extraction with hexane, dichloromethane and methanol were performed to obtain LHR, LDR and LMR extracts from L. cultratus roots, which were characterized by 1H NMR. Promastigotes, amastigotes and peritoneal macrophages were exposed to crescent concentrations of the three extracts, and after incubation, the inhibition rates were determined to both types of cells, and morphological analyses were performed on the parasite. The immunomodulatory activity was determined against stimulated macrophages. KEY FINDINGS LDR, LHR and LMR inhibited promastigote cell growth (IC50 0.62 ± 0.3, 0.94 ± 0.5 and 1.28 ± 0.73 µg/ml, respectively) and reduced the number of amastigotes inside macrophages (IC50 1.36 ± 0.14, 1.54 ± 0.26 and 4.09 ± 0.88 µg/ml, respectively). The cytotoxicity against murine macrophages resulted in a CC50 of 13.12 ± 1.92, 92.93 ± 9.1 and >300 µg/ml, resulting in high selectivity index to promastigotes and amastigotes. The extracts also inhibited the nitric oxide secretion in RAW 264.7 macrophages. The antioxidant capacity resulted in a higher scavenger LMR ability. CONCLUSIONS These results suggest that L. cultratus extracts have anti-Leishmania potential, are non-toxic, and immunosuppress macrophages in vitro.

Determination of fingerprints contents of different extracts and parts of six endemic Salvia taxa by GC-MS: Source species for valuable compounds with drug or drug potential. Biomed Chromatogr 2021; 36:e5263. [PMID: 34647633 DOI: 10.1002/bmc.5263] [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: 06/15/2021] [Revised: 09/30/2021] [Accepted: 10/04/2021] [Indexed: 11/09/2022]
Abstract
Public use of Salvia species and their importance in the scientific world is continually increasing. It is known that this use and the importance of Salvia species are mostly due to the terpenoid compounds that they contain. In this context, the terpenoid-steroid-flavonoid contents of extracts of six endemic Salvia (S. kurdica, S. pseudeuphratica, S. rosifolia, S. siirtica, S. cerino-pruinosa var. cerino-pruinosa and S. cerino-pruinosa var. elazigensis) species prepared with different solvents were determined by gas chromatography-mass spectrometry. Within the framework of the ingredient analysis, content analysis of the ethanol extracts of the root, branch, leaf and flower parts of the species collected in the same period between 2015 and 2017 years was performed. In general, extracts prepared with chloroform and ethanol were found to contain a wide variety of compounds while petroleum ether extracts were found to contain much less varied compounds. In addition, in general, root extracts are richer in terpenoid compounds than aerial part extracts. Some species can be used as source species in terms of ferruginol, cryptanol, 6,7-dehydroroyleanone, lup-(20)29-ene-2α-hydroxy-3β-acetate, salvigenin and β-sitosterol contents (52,114.28, 75,979.08, 101,247.41, 40,071.29, 33,952.13 and 34,010.90 μg analyte/g extract, respectively).

Determination of chemical structure and anti- Trypanosoma cruzi activity of extracts from the roots of Lonchocarpus cultratus (Vell.) A.M.G. Azevedo & H.C. Lima. Saudi J Biol Sci 2021; 28:99-108. [PMID: 33424286 PMCID: PMC7783657 DOI: 10.1016/j.sjbs.2020.08.036] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/16/2019] [Revised: 08/25/2020] [Accepted: 08/25/2020] [Indexed: 10/31/2022] Open
Abstract
Trypanosoma cruzi is the agent of Chagas disease, an infection that affects around 8 million people worldwide. The search for new anti-T. cruzi drugs are relevant, mainly because the treatment of this disease is limited to two drugs. The objective of this study was to investigate the trypanocidal and cytotoxic activity and elucidate the chemical profile of extracts from the roots of the Lonchocarpus cultratus. Roots from L. cultratus were submitted to successive extractions with hexane, dichloromethane, and methanol, resulting in LCH, LCD, and LCM extracts, respectively. Characterization of extracts was done using 1H-RMN, 13C-RMN, CC and TLC. Treatment of T. cruzi forms (epimastigotes, trypomastigotes, and amastigotes) with crescent concentrations of LCH, LCD, and LCM was done for 72, 48, and 48 h, respectively. After this, the percentage of inhibition and IC50/LC50 were calculated. Benznidazole was used as a positive control. Murine macrophages were treated with different concentrations of both extracts for 48 h, and after, the cellular viability was determined by the MTT method and CC50 was calculated. The chalcones derricin and lonchocarpine were identified in the hexane extract, and for the first time in the genus Lonchocarpus, the presence of a dihydrolonchocarpine derivative was observed. Other chalcones such as isocordoin and erioschalcone B were detected in the dichloromethane extract. The dichloromethane extract showed higher activity against all tested forms of T. cruzi than the other two extracts, with IC50 values of 10.98, 2.42, and 0.83 µg/mL, respectively; these values are very close to those of benznidazole. Although the dichloromethane extract presented a cytotoxic effect against mammalian cells, it showed selectivity against amastigotes. The methanolic extract showed the lowest anti-T. cruzi activity but was non-toxic to peritoneal murine macrophages. Thus, the genus Lonchocarpus had demonstrated in the past action against epimastigotes forms of T. cruzi but is the first time that the activity against infective forms is showed, which leading to further studies with in vivo tests.
