[PMID: 38746019 PMCID: PMC11093228 DOI: 10.3389/fchem.2024.1389848] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2024] [Accepted: 03/26/2024] [Indexed: 05/16/2024] Open
Abstract
A series of 16 novel prenylated chalcones (5A-5P) was synthesized by microwave-assisted green synthesis using 5-prenyloxy-2-hydroxyacetophenone and different benzaldehydes. Comparisons were also performed between the microwave and conventional methods in terms of the reaction times and yields of all compounds, where the reaction times in the microwave and conventional methods were 1-4 min and 12-48 h, respectively. The synthesized compounds were characterized using different spectroscopic techniques, including IR, 1H-NMR, 13C-NMR, and LC-HRMS. The antifungal activities of all compounds were evaluated against Sclerotium rolfsii and Fusarium oxysporum under in vitro conditions and were additionally supported by structure-activity relationship (SAR) and molecular docking studies. Out of the 16 compounds screened, 2'-hydroxy-4-benzyloxy-5'-O-prenylchalcone (5P) showed the highest activity against both S. rolfsii and F. oxysporum, with ED50 of 25.02 and 31.87 mg/L, respectively. The molecular docking studies of the prenylated chalcones within the active sites of the EF1α and RPB2 gene sequences and FoCut5a sequence as the respective receptors for S. rolfsii and F. oxysporum revealed the importance of the compounds, where the binding energies of the docked molecules ranged from -38.3538 to -26.6837 kcal/mol for S. rolfsii and -43.400 to -23.839 kcal/mol for F. oxysporum. Additional docking parameters showed that these compounds formed stable complexes with the protein molecules.

Abstract
Through a facile two-step synthetic procedure, three metal-free organic dyes having D-π-A kind of structure, belonging to chalcone family have been designed, produced and anchored on one dimensional cadmium sulfide nanowires (1D CdS NWs) to serve as a light energy harvester through dye-sensitized solar cells (DSSC) assembly. In order to anchor dye on CdS NWs nano-network, solution chemistry has been used in an easy and effective manner. The sensitizing capability of synthesized materials has been evaluated using optical and electrochemical studies, density functional theory (DFT) simulations, and photovoltaic performances. In line with a detailed analysis of fabricated Dye sensitized solar cells containing T4PC a photovoltaic efficiency yields 4.35 times (0.487%) more than that of bare CdS NWs (0.112%), while the other devices having T3PC and T2PC have shown 3.0 (0.338%) and 2.40 (0.273%) times greater photovoltaic efficiencies, respectively under standard light illumination. The obtained results offer solid evidence in favour of boosting external quantum efficiency (EQE) and reflect good agreement with the optical studies.

Abstract
Improved therapies for inflammatory bowel diseases are sorely needed. Novel therapeutic agents and the development of controlled release systems for targeted tissue delivery are interesting approaches to overcome these barriers. We investigated the activity of trans-chalcone (T) in acetic acid-induced colitis in mice and developed, characterized, and determined the therapeutic effect of pectin/casein polymer microcapsules containing T (MT) in a colitis mouse model. In vitro, compound release was achieved in simulated intestinal fluid but not in the simulated gastric fluid. In vivo, since T at the dose of 3 mg/kg but not 0.3 mg/kg ameliorated colitis, we next tested the effects of MT at 0.3 mg/kg (non-effective dose). MT, but not free T at 0.3 mg/kg, significantly improved colitis outcomes such as neutrophil recruitment, antioxidant capacity, cytokine production, and NF-kB activation. This translated into reduced macro and microscopic damage in the colon. T release from the microcapsules is mediated by a pH-dependent and pectinase-regulated mechanism that provide controlled and prolonged release of T. Moreover, MT lowered the required dose for T therapeutic effect, indicating that could be a suitable pharmaceutical approach to colitis treatment. This is the first demonstration that T or MT is effective at reducing the signs of colitis.

Abstract
Abstract
In this study, controlled release of trans-chalcone was achieved by using a polycaprolactone-based hybrid system as the drug carrier material. Encapsulation efficiency was obtained in the range of 70–75% for various formulations and in vitro release studies, conducted at 37 °C and pH 7.4, revealed slow profile reaching 60% cumulative release. As interpreted from kinetic modelling, drug release was controlled mainly by Fickian diffusion; polymer erosion did not contribute to the TC release. Difference in drug loading efficiencies of the hybrid and neat PCL microparticles was observed such that PCL microparticles had lower loading efficiency than the hybrid microparticles whereas the release profiles were similar. pH of the release medium had affected release profiles; acidic medium enhanced drug release. Characterization of the microparticles were realized by FT-IR, TGA, DSC, SEM and WCA which revealed key properties such as molecular dispersion state and hydrophilicity. With the results obtained, we concluded that our hybrid system has a significant potential for long term release of trans-chalcone.

Abstract
This study set out to evaluate novel PCL-based silica containing nanohybrids as the polymer matrix in a hydrophobic drug-loaded microsphere system. Nanohybrids were synthesized by PCL-grafting to NH2-end grouped silica by in situ enzymatic ring opening polymerization of ε-caprolactone. Molecular weight and monomer conversion, PCL grafting percentage, thermal properties and crystallinity of the nanohybrids were determined by 1H NMR, TGA, DSC and XRD. Synthesized nanohybrids had low crystallinity percentage (32 and 39 %) and molecular weight (4800 and 8700 g/mol), promising for controlled drug release applications. The nanohybrids were used for fabrication of trans-chalcone-loaded microspheres by O/W single emulsion solvent evaporation. Mean particle diameter of the microspheres were between 15 and 30 µm. The result of release studies showed that optimum microsphere formulations (AP4 and A2, respectively) had 61 and 64 % encapsulation efficiency. One of the more significant findings to emerge from this investigation is that TC release was extended to 16 and 37 days, in a controlled manner. TC release was significantly enhanced in acidic pH media (pH 3.6 and 5.6) indicating pH-dependent release from nanohybrid microspheres; releasing 80-100 % of the loaded drug in 4-14 days. Drug/polymer interactions and molecular structures were investigated by FT-IR spectroscopy and DSC analysis. According to the results obtained, enzymatically synthesized nanohybrids have potential for pH-dependent release of the model drug, trans-chalcone.

Abstract
This work aimed to investigate, for the first time, the chemical composition, antioxidant, antiparasitic, cytotoxicity, and antimicrobial activities of the aromatic plant Limonium oleifolium Mill. essential oil (EO) and organic extracts. L. oleifolium aerial parts essential oil was analyzed by GC-FID and GC-MS, and 46 constituents representing 98.25±1.12 % of the oil were identified. γ-Muurolene (10.81±0.07 %), cis-caryophyllene (7.71±0.06 %), o-cymene (7.07±0.01 %) and α-copaene (5.02±0.05 %) were the essential oil main compounds. The antioxidant activity of L. oleifolium EO and organic extracts (MeOH, CHCl3 , AcOEt, BuOH) was explored using 2,2-diphenyl-1-picrylhydrazyl (DPPH), ABTS, β-carotene/linoleic acid, cupric reducing antioxidant capacity (CUPRAC), and ferric reducing power assays. The results showed that L. oleifolium EO exhibit antioxidant capacity (IC50 =17.40±1.32 μg/mL for DPPH assay, IC50 =29.82±1.08 μg/mL for β-carotene assay, IC50 =25.23±1.01 μg/mL for ABTS assay, IC50 =9.11±0.08 μg/mL for CUPRAC assay and IC50 =19.41±2.06 mg/mL for reducing power assay). Additionally, the EO showed significant activity against trophozoite form of Acanthamoeba castellanii (IC50 =7.48±0.41 μg/mL) and promastigote form of Leishmania amazonensis (IC50 =19.36±1.06 μg/mL) and low cytotoxicity on murine macrophages (LC50 90.23±1.09 μg/mL), as well as good antimicrobial activity against Staphylococcus aureus, Escherichia coli, Klebsiella oxytoca, and Pseudomonas aeruginosa. These results suggest that L. oleifolium essential oil is a valuable source of bioactive compounds presenting antioxidant, antiparasitic, and antimicrobial activities. Furthermore, it is considered nontoxic.

Abstract
Cutaneous leishmaniasis is a worldwide public health problem. Conventional therapies, in addition to the high cost, have many adverse effects and cases of parasite's resistance. Chalcones are secondary metabolites precursors in the flavonoid pathway and can be obtained naturally, but with low yield from plant raw material. Thus, the use of synthetic chalcones has been a promising strategy for the development of molecules with leishmanicidal activity. Thus, this work aimed to develop a controlled release system of two synthetic chalcone (trans-chalcones and 3'-(trifluormethyl)-chalcone) using polyvinyl alcohol nanofibers (PVA) as scaffold. The association of chalcones to the nanofibers was made by nanoemulsions (NE) thereof, i.e., a colloidal system on a nanometric scale, which allows compounds with opposite polarities to remain miscible and stable throughout their manipulation. Chalcone nanoemulsions were developed using the spontaneous emulsification technique. The NE were characterized regarding their particle size, polydispersion index (PDI), and zeta potential. The results showed NE with spherical shape, absolute values of zeta potential were higher than 30 mV and homogeneous distribution pattern (PDI < 0.3). Dynamics light scattering (DLS) analysis showed similar hydrodynamic rays, i.e., 180 nm (trans-chalcone NE) and 178 nm (NE containing 3'-(trifluormethyl)-chalcone, in addition to presenting encapsulation efficiency values close to 100 %. Subsequently, the NE were added to a polymeric solution of polyvinyl alcohol (PVA) and processed via the electrospinning technique affording a PVA matrix (15 %, w/v) nanofiber containing the chalcones NE at 1 mg.mL-1. In a follow-up experiment, the skin permeation assay of the PVA matrix-chalcone NE was performed in vitro using Franz type diffusion cells and porcine ear as biological model of study. The results showed that the treatments with the nanofibers containing the chalcone NE were retained mainly in the stratum corneum, while the NE suspensions containing chalcone were retained in the epidermis and dermis. This result is thought to be relevant, since parasites are located mainly in the dermis. Further, in vitro assay against the amastigote form of L. (L) amazonensis, showed IC50 values to trans-chalcone and 3'-(trifluormethyl)-chalcone of 24.42 ± 6.76 μg.mL-1 and 15.36 ± 4.61 μg.mL-1, respectively. In addition to improving the solubility of the compounds tested in culture medium without using organic solvents, chalcones in nano-emulsified form reduced the IC50 to 9.09 ± 1.24 μg.mL-1 (trans-chalcone) and 10.27 ± 2.27 μg.mL-1 (3'-(trifluormethyl)-chalcone) which confirmed the potential of the nanoemulsion containing chalcone for cutaneous leishmaniasis treatment.

Abstract
The Leishmaniasis treatment currently available involves some difficulties, such as high toxicity, variable efficacy, high cost, therefore, it is crucial to search for new therapeutic alternatives. Over the past few years, research on new drugs has focused on the use of natural compounds such as chalcones and nanotechnology. In this context, this research aimed at assessing the in vitro leishmanicidal activity of free 4-nitrochalcone (4NC) on promastigotes and encapsulated 4NC on L. amazonensis-infected macrophages, as well as their action mechanisms. Free 4NC was able to reduce the viability of promastigotes, induce reactive oxygen species production, decrease mitochondrial membrane potential, increase plasma membrane permeability, and expose phosphatidylserine, in addition to altering the morphology and lowering parasite cellular volume. Treatment containing encapsulated 4NC in beeswax-copaiba oil nanoparticles (4NC-beeswax-CO Nps) did not alter the viability of macrophages. Furthermore, 4NC-beeswax-CO Nps reduced the percentage of infected macrophages and the number of amastigotes per macrophages, increasing the production of reactive oxygen species, NO, TNF-α, and IL-10. Therefore, free 4NC proved to exert anti-promastigote effect, while 4NC-beeswax-CO Nps showed a leishmanicidal effect on L. amazonensis-infected macrophages by activating the macrophage microbicidal machinery.

Abstract
BACKGROUND New modes of action are needed for herbicides. The flavonoid synthesis intermediate t-chalcone causes apoptosis-like symptoms in roots and bleaching of shoots of Arabidospsis, suggesting a unique mode of action as a phytotoxin. RESULTS Using RNA-Seq, transcriptome changes were monitored in Arabidopsis seedlings during the first 24 h of exposure (at 1, 3, 6, 12 and 24 h) to 21 μm t-chalcone (I50 dose), examining effects on roots and shoots separately. Expression of 892 and 1000 genes was affected in roots and shoots, respectively. According to biological classification, many of the affected genes were transcription factors and genes associated with oxidative stress, heat shock proteins, xenobiotic detoxification, ABA and auxin biosynthesis, and primary metabolic processess. These are secondary effects found with most phytotoxins. Potent phytotoxins usually act by inhibiting enzymes of primary metabolism. KEGG pathway analysis of transcriptome results from the first 3 h of t-chalcone exposure indicated several potential primary metabolism target sites for t-chalcone. Of these, p-hydroxyphenylpyruvate dioxygenase (HPPD) and tyrosine amino transferase were consistent with the bleaching effect of the phytotoxin. Supplementation studies with Lemna paucicostata and Arabidiopsis supported HPPD as the target, although in vitro enzyme inhibition was not found. CONCLUSIONS t-Chalcone is possibly a protoxin that is converted to a HPPD inhibitor in vivo. © 2019 Society of Chemical Industry.

Abstract
BACKGROUND Chemotherapy is a principle tool for the control and prevention of piroplasmosis. The search for a new chemotherapy against Babesia and Theileria parasites has become increasingly urgent due to the toxic side effects of and developed resistance to the current drugs. Chalcones have attracted much attention due to their diverse biological activities. With the aim to discover new drugs and drug targets, in vitro and in vivo antibabesial activity of trans-chalcone (TC) and chalcone 4 hydrate (CH) alone and combined with diminazene aceturate (DA), clofazimine (CF) and atovaquone (AQ) were investigated. METHODOLOGY/PRINCIPAL FINDINGS The fluorescence-based assay was used for evaluating the inhibitory effect of TC and CH on four Babesia species, including B. bovis, B. bigemina, B. divergens, B. caballi, and T. equi, the combination with DA, CF, and AQ on in vitro cultures, and on the multiplication of a B. microti-infected mouse model. The cytotoxicity of compounds was tested on Madin-Darby bovine kidney (MDBK), mouse embryonic fibroblast (NIH/3T3), and human foreskin fibroblast (HFF) cell lines. The half maximal inhibitory concentration (IC50) values of TC and CH against B. bovis, B. bigemina, B. divergens, B. caballi, and T. equi were 69.6 ± 2.3, 33.3 ± 1.2, 64.8 ± 2.5, 18.9 ± 1.7, and 14.3 ± 1.6 μM and 138.4 ± 4.4, 60.9 ± 1.1, 82.3 ± 2.3, 27.9 ± 1.2, and 19.2 ± 1.5 μM, respectively. In toxicity assays, TC and CH affected the viability of MDBK, NIH/3T3, and HFF cell lines the with half maximum effective concentration (EC50) values of 293.9 ± 2.9, 434.4 ± 2.7, and 498 ± 3.1 μM and 252.7 ± 1.7, 406.3 ± 9.7, and 466 ± 5.7 μM, respectively. In the mouse experiment, TC reduced the peak parasitemia of B. microti by 71.8% when administered intraperitoneally at 25 mg/kg. Combination therapies of TC-DA and TC-CF were more potent against B. microti infection in mice than their monotherapies. CONCLUSIONS/SIGNIFICANCE In conclusion, both TC and CH inhibited the growth of Babesia and Theileria in vitro, and TC inhibited the growth of B. microti in vivo. Therefore, TC and CH could be candidates for the treatment of piroplasmosis after further studies.

Abstract
Insulin resistance and inflammation are strongly linked to non-alcoholic fatty liver disease (NAFLD) as a feature of the metabolic syndrome. Furthermore, the role of dysregulation of miR-34a, miR-451, and miR-33a in pathogenesis and progression of NAFLD has been identified. trans-Chalcone is a simple chalcone with anti-diabetic and anti-inflammatory activities. However, to the best of our knowledge, miRNA-dependent mechanisms of these protective effects under pathologic conditions are not understood. Thus, this study, for the first time, aimed to evaluate the effects of trans-Chalcone on miR-34a, miR-451, and miR-33a signaling pathways in the liver of high-fat (HF) emulsion-fed rats. To this aim, twenty-one rats were randomly and equally divided into three groups: control, which was gavaged with 10% tween 80; HF, which was gavaged with HF emulsion and 10% tween 80; and HF + trans-Chalcone (HF + TC), which was gavaged with HF emulsion and trans-Chalcone. Then, circulating levels of glucose and insulin were measured and used for the calculation of HOMA-IR. Hepatic expression levels of miR-34a, miR-451, miR-33a, SIRT1, and ABCA1 and also protein levels of ABCA1 and IL-8 were assayed. In this study, trans-chalcone increased hepatic cholesterol efflux and prevented insulin resistance and liver inflammation in HF emulsion-fed rats. These protective effects were modulated through the down-regulation of miR-34a and its associated elevation of SIRT1, the up-regulation of miR-451 which was associated with a reduction in IL-8, and the inhibition of miR-33a which was related to the elevation of ABCA1 in the liver of HF emulsion-fed rats. Therefore, trans-Chalcone exerts its beneficial effects by targeting hepatic miR-34a-, miR-451-, and miR-33a-related pathways.

Abstract
Conventional chemotherapy of cutaneous leishmaniasis (CL) is based on multiple parenteral or intralesional injections with systemically toxic drugs. Aiming at a single-dose localized therapy, biodegradable poly(lactic-co-glycolic acid) (PLGA) microparticles loaded with 7.8% of an antileishmanial nitrochalcone named CH8 (CH8/PLGA) were constructed to promote sustained subcutaneous release. In vitro, murine macrophages avidly phagocytosed CH8/PLGA smaller than 6 μm without triggering oxidative mechanisms. Upon 48 h of incubation, both CH8 and CH8/PLGA were 40 times more toxic to intracellular Leishmania amazonensis than to macrophages. In vivo, BALB/c were given one or three subcutaneous injections in the infected ear with 1.2 mg/kg of CH8 in free or CH8/PLGA forms, whereas controls received three CH8-equivalent doses of naked PLGA microparticles or meglumine antimoniate (Glucantime; Sanofi-Aventis). Although a single injection with CH8/PLGA reduced the parasite loads by 91%, triple injections with free CH8 or CH8/PLGA caused 80 and 97% reductions, respectively, in relation to saline controls. Meglumine antimoniate treatment was the least effective (only 36% reduction) and the most toxic, as indicated by elevated alanine aminotransferase serum levels. Together, these findings show that CH8/PLGA microparticles can be effectively and safely used for single-dose treatment of CL.

Abstract
Leishmaniases are endemic diseases in tropical and sub-tropical regions of the world and are considered by the World Health Organization (WHO) to be among the six most important neglected tropical diseases. The current therapeutic arsenal against the disease is associated with a series of chemotherapeutic setbacks. However, since the early 1990s, naturally occurring chalcones with promising antileishmanial effects have been reported, and several other synthetic chalcones and chalcone-hybrid molecules have been confirmed to possess potent activity against various Leishmania species. This paper is a comprehensive review covering the antileishmanial activity of 34 naturally occurring chalcones, 224 synthetic/semisynthetic chalcones and 54 chalcone-hybrid molecules. Several chalcones in the synthetic/semisynthetic category had IC50 values < 5 µM, with very good selectivity against parasites, and the structure-activity relationships as well as the proposed mechanism of action are discussed. We identified knowledge-gaps with the hope of providing future direction for the discovery of novel antileishmanial drugs from chalcones.

Abstract
Chalcones display a broad spectrum of pharmacological activities. Herein, a series of 2'-hydroxy methoxylated chalcones was synthesized and evaluated towards Trypanosoma brucei, Trypanosoma cruzi and Leishmania infantum. Among the synthesized library, compounds 1, 3, 4, 7 and 8 were the most potent and selective anti-T. brucei compounds (EC50 = 1.3-4.2 μM, selectivity index >10-fold). Compound 4 showed the best early-tox and antiparasitic profile. The pharmacokinetic studies of compound 4 in BALB/c mice using hydroxypropil-β-cyclodextrins formulation showed a 7.5 times increase in oral bioavailability.

Abstract
The treatment of American cutaneous leishmaniasis (ACL) is based on a small group of compounds that were developed decades ago, all of which are highly toxic and have a high rate of treatment failure. The chalcones show leishmanicidal activity, yet few studies have evaluated this activity against Leishmania (Viannia) braziliensis, one of the most important species of Leishmania across Latin America. Four new synthetic chalcones (1-4) were evaluated for inhibitory activity in vitro against promastigotes and intracellular parasites 24h post infection of L. (V.) braziliensis, cytotoxicity for macrophages J774.A1 and red blood cells, and the ability to stimulate nitric oxide production. The results for the inhibitory concentration for 50% of the promastigotes (IC50) (1.38±1.09-6.36±2.04μM), cytotoxic concentration for 50% of the macrophages (CC50) (13.49±3.13-199.43±4.11μM), and selectivity index (SI) (3.76 to 33.94) indicate that all chalcones (1-4) showed an effect on promastigotes of L. (V.) braziliensis; chalcone 2 had the highest SI. The haemolytic assay with chalcones 1 (301.93μM), 2 (534.18μM), 3 (419.46μM) and 4 (381.11μM) showed 0.00%, 2.33%, 0.57% and 1.74% haemolysis, respectively. All chalcones significantly reduced the infection index of macrophages by parasites; for chalcones (1-3) this effect may be dependent on nitric-oxide production by macrophages. The chalcones tested exhibited inhibitory activity for promastigotes and intracellular parasites of L. (V.) braziliensis, with low toxicity for macrophages and red blood cells. The anti-Leishmania activity of chalcones (1-3) may depend on the stimulation of nitric-oxide production in the initial stage of infection. These results show an initially encouraging potential for the use of chalcones (1-4) to treat ACL.

Abstract
In this work we described the synthesis, the antileishmanial activity and the molecular modeling and structure-activity relationship (SAR) evaluations of a series of chalcone derivatives. Among these compounds, the methoxychalcones 2h, 2i, 2j, 2k and 2l showed significant antileishmanial activity (IC(50)<10 μM). Interestingly 2i (IC(50)=2.7 μM), 2j (IC(50)=3.9 μM) and 2k (IC(50)=4.6 μM) derivatives presented better antileishmanial activity than the control drug pentamidine (IC(50)=6.0 μM). Our SAR study showed the importance of methoxy di-ortho substitution at phenyl ring A and the relationship between the frontier orbital HOMO coefficients distribution of these molecules and their activity. The most active compounds 2h, 2i, 2j, 2k, and 2l fulfilled the Lipinski rule-of-five which theoretically is important for good drug absorption and permeation through biological membranes. The potential profile of 2j (IC(50)=3.9 μM and CC(50)=216 μM) pointed this chalcone derivative as a hit compound to be further explored in antileishmanial drug design.

Abstract
Miltefosine has been established as the first oral administration drug against cutaneous and visceral leishmaniasis. Other alkyl-phospholipids such as edelfosine have been tested against Leishmania showing an in vitro antiparasitic activity. Perifosine in vitro activity has been previously demonstrated against different Leishmania species including Leishmania amazonensis. In this study edelfosine and perifosine were orally administered to BALB/c mice at doses of 1 and 2.5 mg/kg/day during 28 days and 5 mg/kg/day during 14 days, starting the treatment 2 weeks after the first treatment scheme. Lesion sizes and parasitic burden as well as viability were determined in order to establish the treatment effectiveness. An assay to compare miltefosine at standard dose of 2.5 mg/kg/day during 28 days to an in vivo treatment with perifosine at the most effective treatment scheme observed in this study 5 mg/kg/day during 14 days, was also developed. Perifosine showed the higher activity in the in vivo assay and is showing as a new possibility within the alkyl-phospholipids group for the treatment against cutaneous leishmaniasis caused by L. amazonensis.

Abstract
Perifosine is a novel alkylphospholipid. Perifosine has displayed significant antiproliferative activity in vitro and in vivo in several human tumor model systems and has recently entered phase II clinical trials. Other alkylphospholipids have been previously used as antileishmanial agents, and miltefosine (Impavido) is now established as the first oral drug for the treatment of visceral and cutaneous leishmaniasis. Perifosine showed the higher activity against all tested strains. This study demonstrates for, the first time, an in vitro activity of perifosine against different species of Leishmania in the promastigote stage.
