Anticholinesterase Activity of Methanolic Extract of Amorpha fruticosa Flowers and Isolation of Rotenoids and Putrescine and Spermidine Derivatives. PLANTS (BASEL, SWITZERLAND) 2024; 13:1181. [PMID: 38732396 PMCID: PMC11085544 DOI: 10.3390/plants13091181] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/24/2024] [Revised: 04/15/2024] [Accepted: 04/19/2024] [Indexed: 05/13/2024]
Abstract
Five putrescine and spermidine derivatives (1-5) together with five rotenoids (6-10) were isolated from a methanolic extract of the flowers of A. fruticosa that displayed promising inhibition of 76.0 ± 1.9% for AChE and 90.0 ± 4.0% for BuChE at a concentration of 1 mg/mL. Although the anticholinesterase activities of the isolated compounds did not reach that of galantamine, molecular docking revealed that all-trans-tri-p-coumaroylspermidine and trans-trans-cis-tri-p-coumaroylspermidine showed binding poses mimicking the known inhibitor galantamine and thus could serve as model molecules in future searches for new AChE and BuChE inhibitors.

Chemical Composition, Antipathogenic and Cytotoxic Activity of the Essential Oil Extracted from Amorpha fruticosa Fruits. Molecules 2021; 26:molecules26113146. [PMID: 34074063 PMCID: PMC8197342 DOI: 10.3390/molecules26113146] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2021] [Revised: 05/16/2021] [Accepted: 05/21/2021] [Indexed: 11/24/2022] Open
Abstract
The purpose of this paper was to characterize and investigate the antimicrobial potential of Amorpha fruticosa fruits essential oil (EO). The EO was extracted by hydrodistillation, analyzed by GC-MS, and then evaluated for its interaction with microbial and mammalian cells. The antimicrobial activity was assessed against bacterial and fungal strains, in a planktonic and adherent growth state, using qualitative and quantitative assays. The main components identified in A. fruticosa fruits EO were δ-cadinene, γ-muurolene, and α-muurolene. The Gram-positive strains proved to be more susceptible than Gram-negative bacteria and fungal strains. The EO exhibited good antibiofilm activity, inhibiting the microbial adherence to the inert (96-well plates and Foley catheter section) and cellular substrata. The flow cytometry analysis revealed as one of the possible mechanisms of antimicrobial action the alteration of cell membrane hydrophobicity. The cytotoxicity on the L929 cell line occurred at concentrations higher than 0.3 mg/mL. Taken together, our results demonstrate that A. fruticosa fruits EO contains active compounds with selective inhibitory effect on different microbial strains in planktonic and biofilm growth state, explained at least partially by the interference with microbial membranes due to their hydrophobic character.
