Abstract
The development of new drugs derived from plant sources is of significant interest in modern pharmacy. One of the promising plant sources for introduction into pharmaceuticals is Tripleurospermum inodorum (L.) Sch. Bip., also known as Tripleurospermum perforatum (Merat.) M. This plant has been shown to possess various biological activities, including anti-inflammatory, antimicrobial, and antimycotic activities, among others. However, a review of the current literature reveals a paucity of studies investigating the chemical composition of the herb Tripleurospermum inodorum (L.) Sch. Bip. This study presents the development of a method for obtaining an extract of the herb Tripleurospermum inodorum (L.) Sch. Bip. enriched with flavonoids, harvested before flowering and butonization. This study focused on determining the optimal conditions for extraction, including the concentration of the extractant (ethanol), extraction time, raw material/extractant ratio, extraction frequency, complexation reaction time, amount of aluminum chloride solution, and amount of diluted acetic acid. The results indicate that herbs harvested during this specific period exhibited a higher flavonoid content compared to those collected during butonization and flowering. Moreover, this study demonstrated that the flavonoid content could exceed 7% mg REq/100 g D.W. through a one-hour extraction process. Furthermore, the flavonoid content was found to be 7.65 ± 0.03 mg REq/100 g D.W. following a three-minute ultrasound-assisted extraction process, followed by thermal extraction. A qualitative analysis identified a variety of phenolic compounds in the extract, such as chlorogenic acid, 5-O-p-coumaroylquinic acid, 1-O-p-coumaroylquinic acid, luteolin-7-glucoside, quercetin-3-glucoside, luteolin-7-rutinoside, 3,5-O-dicaffeoylquinic acid, quercetin-3-O-malonylglucoside, apigenin-7-glucoside, luteolin-3-malonylglucoside, cynarin, rhamnetin-3-(O-dimethyl rhamnosyl glucosylglucoside), and luteolin. Moreover, this study demonstrated the antimicrobial, anti-inflammatory, anticoagulant, anti-aggregation, and antioxidant activities of the aqueous alcoholic extract from T. inodorum herb (ETIH) against pathogens such as Staphylococcus aureus, Escherichia coli, and Candida albicans. Additionally, the extract exhibited comparable anti-inflammatory effects on diclofenac sodium. These findings contribute to the understanding of the potential pharmacological applications of the developed herb extract.

Effects of Tripleurospermum caucasicum, Salvia rosmarinus and Tanacetum fruticulosum essential oils on aflatoxin B 1 production and aflR gene expression in Aspergillus flavus. Int J Food Microbiol 2024; 415:110639. [PMID: 38417281 DOI: 10.1016/j.ijfoodmicro.2024.110639] [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: 10/17/2023] [Revised: 02/05/2024] [Accepted: 02/21/2024] [Indexed: 03/01/2024]
Abstract
Aflatoxin B1 (AFB1) is one of the most hazardous mycotoxins for humans and livestock that mainly produced by members of the genus Aspergillus in a variety of food commodities. In this study, the effect of S. rosmarinus, T. fruticulosum, and T. caucasicum essential oils (EOs) was studied on fungal growth, AFB1 production and aflR gene expression in toxigenic A. flavus IPI 247. The AFB1 producer A. flavus strain was cultured in YES medium in presence of various two-fold concentrations of the plant EOs (62.5-500 μg/mL) for 4 days at 28 °C. EO composition of plants was analyzed by Gas Chromatography/Mass Spectrometry (GC/MS). The amount of fungal growth, ergosterol content of fungal mycelia and AFB1 content of EO-treated and non-treated controls were measured. The expression of aflR gene was evaluated using Real-time PCR in the fungus exposed to minimum inhibitory concentration (MIC50) of EOs. The main constituents of the oils analyzed by GC/MS analysis were elemicin (33.80 %) and 2,3-dihydro farnesol (33.19 %) in T. caucasicum, 1,8-cineole (17.87 %), trans-caryophyllene (11.14 %), α and ẞ-pinene (10.92 and 8.83 %) in S. rosmarinus, and camphor (17.65 %), bornyl acetate (15.08 %), borneol (12.48 %) and camphene (11.72 %) in T. fruticulosum. The results showed that plant EOs at the concentration of 500 μg/mL suppressed significantly the fungal growth by 35.24-71.70 %, while mycelial ergosterol content and AFB1 production were inhibited meaningfully by 36.20-65.51 % and 20.61-89.16 %. T. caucasicum was the most effective plant, while T. fruticulosum showed the lowest effectiveness on fungal growth and AFB1 production. The expression of aflR in T. caucasicum and S. rosmarinus -treated fungus was significantly down-regulated by 2.85 and 2.12 folds, respectively, while it did not change in T. fruticulosum-treated A. flavus compared to non-treated controls. Our findings on the inhibitory activity of T. caucasicum and S. rosmarinus EOs toward A. flavus growth and AFB1 production could promise these plants as good candidates to control fungal contamination of agricultural crops and food commodities and subsequent contamination by AFB1. Down-regulation of aflR as the key regulatory gene in AF biosynthesis pathway warrants the use of these plants in AF control programs. Further studies to evaluate the inhibitory activity of studied plants EOs in food model systems are recommended.

Abstract
Aspergillus species consists of a group of opportunistic fungi that is virulent when the immunity of the host is compromised. Among the various species, Aspergillus fumigatus is the most prevalent species. However, the prevalence of fungal infections caused by non-fumigatus Aspergillus has been increasing. Polyenes, echinocandins and azoles are the three main classes of antifungal agents being used for the treatment of aspergillosis. Nevertheless, the incidence of resistance towards these three classes has been rising over the years among several Aspergillus spp. The side effects associated with these conventional antifungal agents have also limited their usage. This urges the need for the discovery of a safe and effective antifungal agent, which presents a major challenge in medicine today. Plants present a rich source of bioactive molecules which have been proven effective against a wide range of infections and conditions. Therefore, this present review intends to examine the current literature available regarding the efficacy and mechanism of action of plant extracts and their compounds against Aspergillus spp. In addition, novel drug delivery systems of plant extracts against Aspergillus spp. were also included in this review.

Comparative Assessment of the Phytochemical Composition and Biological Activity of Extracts of Flowering Plants of Centaurea cyanus L., Centaurea jacea L. and Centaurea scabiosa L. PLANTS 2021; 10:plants10071279. [PMID: 34201790 PMCID: PMC8309150 DOI: 10.3390/plants10071279] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/09/2021] [Revised: 06/09/2021] [Accepted: 06/16/2021] [Indexed: 11/16/2022]
Abstract
The data on the phytochemical composition and biological activity for flowering plant extracts of the genus Centaurea (Knapweed)-cornflower (Centaurea cyanus L.), brown knapweed (Centaurea jacea L.), and greater knapweed (Centaurea scabiosa L.), which are typical representatives of the flora in the middle belt of the Russian Federation, were obtained. For the first time, biologically active substances such as pyranone, coumaran (2,3-dihydrobenzofuran), and 5-hydroxymethylfurfural were identified in ethanol and methanol extracts of Centaurea scabiosa L. by gas chromatography-mass spectrometry. Catechol and α-amyrin were the major components of the ethanol extract from Centaurea cyanus L., and flavone was the major component of Centaurea jacea L. flower extract. The greatest antimicrobial activity against phytopathogens was detected in Centaurea scabiosa L. when extracting freshly harvested flower biomass with methyl tert-butyl ether at room temperature: the minimum inhibitory concentrations were 60-120 µg/mL, the minimum fungicidal concentration was 120 µg/mL, and the minimum bactericidal concentration was 250 µg/mL. The low antioxidant activity of the studied plant extracts was established using the maximum values of Centaurea jacea L. Ethanol extract of Centaurea cyanus L. flowers had low antimicrobial and antioxidant activity. The extracts showed no phytotoxicity to garden cress germination but inhibited the growth of juvenile plants, especially roots. The greatest phytotoxic effect was revealed with methyl tert-butyl ether, where the depression of growth indicators was 35% or more.

Abstract
Objective Burn injuries are among the most common accidental health problems worldwide, frequently leading to health and socio-economic challenges. Despite this, no standard protocol for managing burn injuries can overcome the adverse effects of currently used drugs. The present study sets out to develop and evaluate the efficacy of new herbal ointments in providing synergistic anti-inflammatory, antimicrobial, antioxidant, and cell-proliferating activities. It also investigates the high-performance liquid chromatography (HPLC) characterisation of these new herbal ointments. Method Three different concentrations of the new herbal ointment, which incorporates extracts of Matricaria aurea flower heads, arial parts of Calendula tripterocarpa, Rosmarinus officinalis leaves, Alkanna tinctoria roots, and myrrh were developed and evaluated. Ointments designed to promote burn-wound healing were prepared and compared with β-sitosterol ointment and silver sulfadiazine cream, as a commercial standards. Results According to statistical and histopathological analyses and visual inspections, the new herbal formulas showed faster wound healing, more tolerability, and less toxicity than the commercial standards. Conclusion The new herbal ointments, developed in our study, have shown promising results. The formula offers mechanical protection without any release of non-biodegradable particles. It maintains the optimum moisture and pH of the skin, while minimising scar-tissue formation. These advantages, in addition to availability, low costs, and easy handling, may support the use of this new herbal formula as an effective and safe alternative treatment, designed to promote the healing of burn injuries.

Abstract
Bacterial peptide deformylase (PDF) is an attractive target for developing novel inhibitors against several types of multidrug-resistant bacteria. The objective of the current study is to retrieve potential phytochemicals as prospective drugs against Staphylococcus aureus peptide deformylase (SaPDF). The current study focuses on applying ligand-based pharmacophore model (PharmL) and receptor-based pharmacophore (PharmR) approaches. Utilizing 20 known active compounds, pharmL was built and validated using Fischer's randomization, test set method and the decoy set method. PharmR was generated from the knowledge imparted by the Interaction Generation protocol implemented on the Discovery Studio (DS) v4.5 and was validated using the decoy set that was employed for pharmL. The selection of pharmR was performed based upon the selectivity score and further utilizing the Pharmacophore Comparison module available on the DS. Subsequently, the validated pharmacophore models were escalated for Taiwan Indigenous Plants (TIP) database screening and furthermore, a drug-like evaluation was performed. Molecular docking was initiated for the resultant compounds, employing CDOCKER (available on the DS) and GOLD. Eventually, the stability of the final PDF⁻hit complexes was affirmed using molecular dynamics (MD) simulation conducted by GROMACS v5.0.6. The redeemed hits demonstrated a similar binding mode and stable intermolecular interactions with the key residues, as determined by no aberrant behaviour for 50 ns. Taken together, it can be stated that the hits can act as putative scaffolds against SaPDF, with a higher therapeutic value. Furthermore, they can act as fundamental structures for designing new drug candidates.
