Potential of Exopolysaccharide from Porphyridium marinum to Contend with Bacterial Proliferation, Biofilm Formation, and Breast Cancer. Mar Drugs 2021; 19:66. [PMID: 33513982 PMCID: PMC7911520 DOI: 10.3390/md19020066] [Citation(s) in RCA: 18] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/23/2020] [Revised: 01/21/2021] [Accepted: 01/22/2021] [Indexed: 12/18/2022] Open
Abstract
Exopolysaccharide (EPS) from marine microalgae are promising sources of a new generation of drugs. However, lot of them remain to be discovered and tested. In this study, EPS produced by Porphyridium marinum and its oligomers prepared by High Pressure Homogenizer have been tested for different biological activities, i.e., antibacterial, anti-fungal and antibiofilm activities on Candida albicans, as well as for their effects on the viability of murine breast cancer cells. Results have shown that all EPS samples present some biological activity. For antibacterial and antibiofilm activities, the native EPS exhibited a better efficiency with Minimum Inhibitory Concentration (MIC) from 62.5 µg/mL to 1000 µg/mL depending on the bacterial strain. For Candida albicans, the biofilm formation was reduced by about 90% by using only a 31.3 µg/mL concentration. Concerning breast cancer cells, lower molar masses fractions appeared to be more efficient, with a reduction of viability of up to 55%. Finally, analyses of polymers composition and viscosity measurements were conducted on all samples, in order to propose hypotheses involving the activities caused by the intrinsic properties of polymers.

Bacillomycin D and its combination with amphotericin B: promising antifungal compounds with powerful antibiofilm activity and wound-healing potency. J Appl Microbiol 2016; 120:289-300. [PMID: 26669801 DOI: 10.1111/jam.13030] [Citation(s) in RCA: 26] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/31/2015] [Revised: 11/10/2015] [Accepted: 12/04/2015] [Indexed: 12/31/2022]
Abstract
AIMS In this study, we evaluated the ability of the lipopeptide bacillomycin D and the antifungal drug amphotericin B as well as their combination, to inhibit Candida albicans biofilm formation and to accelerate keratinocyte cell migration. METHODS AND RESULTS The antibiofilm activity of bacillomycin D and its combination with amphotericin B was carried out by crystal violet colorimetric method. Our results have shown that, when combined together at low concentrations nontoxic to mammalian cells, corresponding to 1/32 MIC (0·39 μg ml(-1) ) and 1/4 MIC (0·06 μg ml(-1) ) for bacillomycin D and amphotericin B, respectively, a clear antibiofilm activity is manifested (95% inhibition of biofilm formation) along with a clear inhibition of germ tube formation. Moreover, the effect of both drugs on preformed biofilm of C. albicans strain was determined using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) reduction assay. The combination of the two antifungal compounds at 0·39 and 1 μg ml(-1) for bacillomycin D and amphotericin B, respectively, resulted in a clear enhancement of biofilm eradication compared to the results obtained with each drug alone. Furthermore, this combination was found to promote the closure of a gap produced in a monolayer of human keratinocytes. CONCLUSIONS Bacillomycin D and its combination with amphotericin B display impressive anti-biofilm and wound-healing activities. SIGNIFICANCE AND IMPACT OF THE STUDY Application of the lipopeptide bacillomycin D and the antifungal drug amphotericin B in medical devices may offer a promising alternative for topical treatment of Candida-associated infections in the setting of a wound.

Antifungal activity of Coriandrum sativum essential oil, its mode of action against Candida species and potential synergism with amphotericin B. PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2011; 19:42-47. [PMID: 21788125 DOI: 10.1016/j.phymed.2011.06.033] [Citation(s) in RCA: 79] [Impact Index Per Article: 6.1] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/18/2011] [Revised: 05/17/2011] [Accepted: 06/25/2011] [Indexed: 05/31/2023]
Abstract
The increasing incidence of drug-resistant pathogens and toxicity of existing antifungal compounds has drawn attention towards the antimicrobial activity of natural products. The aim of the present study was to evaluate the antifungal activity of coriander essential oil according to classical bacteriological techniques, as well as with flow cytometry. The effect of the essential oil upon germ tube formation, seen as an important virulence factor, and potential synergism with amphotericin B were also studied. Coriander essential oil has a fungicidal activity against the Candida strains tested with MLC values equal to the MIC value and ranging from 0.05 to 0.4% (v/v). Flow cytometric evaluation of BOX, PI and DRAQ5 staining indicates that the fungicidal effect is a result of cytoplasmic membrane damage and subsequent leakage of intracellular components such as DNA. Also, concentrations bellow the MIC value caused a marked reduction in the percentage of germ tube formation for C. albicans strains. A synergetic effect between coriander oil and amphotericin B was also obtained for C. albicans strains, while for C. tropicalis strain only an additive effect was observed. This study describes the antifungal activity of coriander essential oil on Candida spp., which could be useful in designing new formulations for candidosis treatment.

Abstract
An increased infection incidence of Candida albicans (most common human fungal pathogen) contributes to the need of further functional genetic studies and development of new antifungal drugs. We developed a method to create mutants of C. albicans using an antisense cDNA library to interfere with gene expression, followed by screening for hypersensitivity to Calcofluor White (CFW) and the antifungal drugs caspofungin and itraconazole. Mutants with these properties have with a high probability defects in cell-wall integrity. Fifty out of 200 transformant colonies analyzed (25%) showed hypersensitivity to CFW compared with the parental strain C. albicans CAI-4. Most of those CFW-hypersensitive mutants further displayed the susceptibility to antifungal drugs itraconazole and caspofungin using microbroth dilution method M27-A and an agar-diffusion test. The mutants obtained through this procedure could provide a potential model for screening antifungal pro-drugs which show weak action when standard C. albicans strain is used and may also aid in further identifying genes involved in cell integrity. In addition, we describe the effect of varying several parameters in electroporation transformation, including treatment with lithium acetate, upon the efficiency of transformation in C. albicans.
