Abstract
Infections of fungal origin are mainly caused by Candida spp. Some species, such as C. albicans, C. glabrata, C. parapsilosis, and C. tropicalis, stand out as promoters of diseases in humans. This study evaluated the synthesis and antifungal effects of (E)-3-(furan-2-yl)acrylic acid. The synthesis of the compound showed a yield of 88%, considered high. The minimum inhibitory concentration of the synthetic compound, amphotericin B, and fluconazole isolated against four Candida species ranged from 64 to 512 μg/mL, 1 to 2 μg/mL, and 32 to 256 μg/mL, respectively. The synergistic effect of the test compound was observed when associated with amphotericin B against C. albicans and C. tropicalis, with no antagonism between the substances against any of the strains tested. The potential drug promoted morphological changes in C. albicans, decreasing the amount of resistance and virulence, and reproduction structures, such as the formation of pseudohyphae, blastoconidia, and chlamydospores. Furthermore, it was also possible to identify the fungistatic profile of the test substance by studying the growth kinetics of C. albicans. Finally, it was observed that the test compound stimulated ergosterol biosynthesis by the yeast, probably by activating microbial resistance responses.

Overcoming Drug Resistance in a Clinical C. albicans Strain Using Photoactivated Curcumin as an Adjuvant. Antibiotics (Basel) 2023; 12:1230. [PMID: 37627652 PMCID: PMC10451318 DOI: 10.3390/antibiotics12081230] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/09/2023] [Revised: 07/23/2023] [Accepted: 07/24/2023] [Indexed: 08/27/2023] Open
Abstract
The limited antifungal drugs available and the rise of multidrug-resistant Candida species have made the efforts to improve antifungal therapies paramount. To this end, our research focused on the effect of a combined treatment between chemical and photodynamic therapy (PDT) towards a fluconazole-resistant clinical Candida albicans strain. The co-treatment of PDT and curcumin in various doses with fluconazole (FLC) had an inhibitory effect on the growth of the FLC-resistant hospital strain of C. albicans in both difusimetric and broth microdilution methods. The proliferation of the cells was inhibited in the presence of curcumin at 3.125 µM and FLC at 41 µM concentrations. The possible involvement of oxidative stress was analyzed by adding menadione and glutathione as a prooxidant and antioxidant, respectively. In addition, we examined the photoactivated curcumin effect on efflux pumps, a mechanism often linked to drug resistance. Nile Red accumulation assays were used to evaluate efflux pumps activity through fluorescence microscopy and spectrofluorometry. The results showed that photoactivated curcumin at 3.125 µM inhibited the transport of the fluorescent substrate that cells usually expel, indicating its potential in combating drug resistance. Overall, the findings suggest that curcumin, particularly when combined with PDT, can effectively inhibit the growth of FLC-resistant C. albicans, addressing the challenge of yeast resistance to azole antifungals through upregulating multidrug transporters.

Abstract
Candida spp. cause fungal infection that affects patients' oral health. This study aimed to evaluate the isolated and synergistic antifungal effect of Rosa centifolia L., Curcuma longa L., Rosmarinus officinalis L., and Punica granatum L. glycolic extracts against Candida albicans, Candida dubliniensis, Candida tropicalis, and Candida krusei planktonic and biofilm forms. The plant extracts were chemically characterized and the main compounds were quantified by high-performance liquid chromatography (HPLC-DAD) analysis. The minimum inhibitory and minimum fungicidal concentrations of the extracts were determined, and antibiofilm activity was evaluated by MTT assay. Data were analyzed by one-way ANOVA and Tukey's tests, and by Kruskal-Wallis and Dunn's tests, considering a significance level of 5%. The main compounds identified in each of the extracts were: p-coumaric acid (2153.22 μg/100 mL) in the rosemary extract, gallotannins (4318.31 μg/100 mL) in the pomegranate extract, quercetin derivatives (3316.50 μg/100 mL) in the extract of white roses, and curcumin (135.09 μg/100 mL) in the turmeric extract. The combination of R. centifolia and C. longa glycolic extracts was effective against C. albicans, C. dubliniensis, and C. tropicalis biofilms over different periods (p < 0.05). The combination of R. officinalis and P. granatum glycolic extracts was effective against C. albicans and C. krusei biofilms after 30 min, and against C. tropicalis after 24 h, with all combinations showing an average reduction of 50% in cell viability (p < 0.05). In conclusion, the combined plant extracts have antifungal and antibiofilm action against Candida spp. in different concentrations and times of action.

Abstract
Candida species, for women are the foremost common cause of parasitic contaminations. Candida species affect contamination in 75% of women and at slightest 6-9% of women involvement repetitive vulvovaginal candidiasis. Candida albicans (CA) accounts for 85-95% of yeast strains separated from the vagina. The treatment which has been administered for candida infections is antifungal drugs such as clotrimazole and fluconazole. When applied topically, synthetic antifungal drugs cause allergic reactions, resistance, and a burning sensation. It is necessary to conduct research on plant-based herbal medicine as an alternative treatment. Kemangi, also recognized as Ocimum Basilicum (OB), is a plant native to Indonesia which has medicinal properties. The objective of this study is to examine how effective OB methanol extract is against CA colonies. The study was performed at Brawijaya University's Microbiology Laboratory in Malang. The experimental laboratories with Posttest Only Control Group Design were employed in this study, with four repetitions of OB concentrations of 15%, 20%, 25%, 30%, and 35% against CA colonies. One-way ANOVA was utilized as the hypothesis test, with a significance level of 0.05. The results demonstrated that OB extract with a concentration of 15% was able to inhibit the growth of CA colonies. In the OB extract with a concentration of 35%, no CA colony growth was revealed. One-way ANOVA test obtained p 0.000 <0.05. Conclusion OB owns adequacy in restraining the development of CA organism with negligible murdering rate at a concentration of 35%. Research required to be performed to identify the antifungal potential of OB extract in vivo.

Abstract
Due to the increase in fungal resistance to existing drugs, a need exists to search for new antifungals. This study aimed to evaluate the antifungal activity of α, β, and δ-damascone and inclusion complexes with β-cyclodextrin against different Candida spp. The inclusion complex of β-damascone was prepared by the co-evaporation method using three molar proportions (1:1; 2:1; 3:1 (βDA-βCD)) and analyzed using Fourier transform infrared spectroscopy (FTIR). Standard Candida albicans (CA INCQS 40,006), Candida krusei (CK INCQS 40,095), and Candida tropicalis (CT INCQS 40,042) strains were used to evaluate antifungal activity. The substances were tested individually or in association with fluconazole (FCZ). The IC50 and cell viability curve constructions were performed using the microdilution method. The minimum fungicidal concentration (MFC) was determined by the subculture method in a solid medium. The α, β, and δ-DA isolated or in combination with fluconazole (FCZ) showed significant antifungal activity. β-damascone showed effective complexation in the three molar proportions assayed; however, none of the inclusion complexes was demonstrated clinically significant effects against the fungal tested. Then, all compounds have shown promising antifungal activities; however, in vivo assays are necessary to have therapeutical application in the future.

An Insight on the Role of Nitric Oxide in Yeast Apoptosis of Curcumin-Treated Candida albicans. Curr Microbiol 2020; 77:3104-3113.

Abstract
Nitric Oxide (NO) is a widely studied molecule due to its diverse biological functions. One of its activities, induction of apoptosis, is currently an area of active investigation in mammalian cells. However, there exists little information regarding the role of NO in yeast apoptosis. In an effort to investigate the mode of action by which NO induces programmed cell death in Candida albicans, we conducted a study on curcumin, a major bioactive compound, which is known as a potential apoptosis-inducing material due to several of its biological activities. First, NO generation was evaluated upon curcumin treatment. It is widely known that NO production is closely tied to cellular respiration, which is regulated by mitochondria. An increase in NO concentration leads to the inhibition of respiration and mitochondrial dysfunction. The hallmarks of mitochondrial dysfunction include a decrease in mitochondrial membrane potential along with increased mitochondrial mass, calcium concentration and ROS generation. A specific oxidative ROS compound, superoxide ([Formula: see text]), is strongly reactive with NO to form peroxynitrite (ONOO-). ONOO- disturbs intracellular redox levels, decreasing the overall ratio of glutathione (GSH). This leads to oxidative damage in C. albicans, triggering lethal DNA damage that eventually results in apoptosis. In the present study, a nitric oxide synthase (NOS) inhibitor, L-NG-Nitroarginine Methyl Ester (L-NAME), was used in each experiment. In all experiments, L-NAME pre-treatment of cells blocked the effects induced by curcumin, which indicates that nitric oxide is a component of the overall mechanism. In conclusion, NO account for an indispensable position in apoptosis of curcumin-treated C. albicans.

Abstract
The emergence of fungal resistance to commercial drugs has been a major problem for the WHO. In this context, research with natural products is promising in the discovery of new active substances. Thus, this work evaluated the antifungal effect of a medicinal plant (i.e., Mesosphaerum suaveolens) against strains of the genus Candida, tested the combined effect with the drug fluconazole, and, finally, determined the phenolic constituents present in the species. Initially, aqueous extracts of leaves (AELMs) and aerial parts (AEAPMs) of the species were prepared. For microbiological assays, the minimum fungicidal concentration was determined by broth microdilution, and the combined effect of fluconazole extracts were verified by sub-inhibitory microdilution concentrations (CFM/8) followed by spectrophotometric readings which were used to determine the IC50. HPLC detected the presence of flavonoids and phenolic acids, detecting eight compounds present in the samples of which caffeic acid and quercetin were major components. The AELMs modulated fluconazole activity since it decreased fluconazole's IC50 from 7.8 µg/mL to an IC50 of 4.7 µg/mL (CA LM 77) and from 28.8 µg/mL to 18.26 µg/mL (CA INCQS 40006) for the C. albicans strains. The AEAPMs were able to potentiate the effect of fluconazole more effectively than the AELMs. Such an effect was significant for the 16 µg/mL concentration for CA LM 77 and 32 µg/mL for CA INCQS 40006. The AEAPMs as well as the AELMs presented clinically relevant activities for C. tropicalis strains. For the C. tropicalis LM 23 strain, the AEPMs obtained an IC50 of 25 µg/mL and the AELMs an IC50 of 359.9 µg/mL.

Abstract
The aim of this study was to identify and evaluate the chemical compositions and effects of the S. tuberosa leaf and root hydroalcoholic extracts (HELST and HERST) against different strains of Candida. Chemical analysis was performed by Ultra-Performance Liquid Chromatography Coupled to Quadrupole/Time of Flight System (UPLC-MS-ESI-QTOF). The Inhibitory Concentration of 50% of the growth (IC50) as well as the intrinsic and combined action of the extracts with the antifungal fluconazole (FCZ) were determined by the microdilution method while the minimum fungicidal concentrations (MFCs) and the effect on fungal morphological transitions were analyzed by subculture and in humid chambers, respectively. From the preliminary phytochemical analysis, the phenols and flavonoids were the most abundant. The intrinsic IC50 values for HELST ranged from 5716.3 to 7805.8 µg/mL and from 6175.4 to 51070.9 µg/mL for the HERST, whereas the combination of the extracts with fluconazole presented IC50 values from 2.65 to 278.41 µg/mL. The MFC of the extracts, individually, for all the tested strains was ≥16384 µg/mL. When fluconazole was combined with each extract, the MFC against CA URM 5974 was reduced (HELST: 2048 and HERST: 4096 µg/mL). Synergism was observed against standard C. albicans (CA) and C. tropicalis (CT) strains and with the root extract against the CT isolate. The leaf extract inhibited the morphological transition of all strains while the root extract inhibited only CT strains.
