Propolis Extract

Objective. To evaluate the antimicrobial activity of soft and purified propolis extracts. Study object and methods. Antimicrobial activity of soft and purified propolis extracts was determined with reference cultures of Staphylococcus aureus ATCC 25923, Enterococcus faecalis ATCC 29212, Escherichia coli ATCC 25922, Klebsiella pneumoniae ATCC 33499, Pseudomonas aeruginosa ATCC 27853, Proteus mirabilis ATCC 12459, Bacillus subtilis ATCC 6633, Bacillus cereus ATCC 8035, and fungus Candida albicans ATCC 60193. Microbiological tests were performed under aseptic conditions. Minimum inhibitory concentration (MIC) – the highest dilution of preparation (the lowest concentration of preparation) that suppresses growth of reference microorganisms – was determined. Results. Concentration of phenolic compounds in soft propolis extract that possesses antimicrobial activity against gram-positive (Staphylococcus aureus, Enterococcus faecalis) and gram-negative bacteria (Escherichia coli, Pseudomonas aeruginosa, and Proteus mirabilis) is 0.587±0.054 mg and 0.587±0.054–0.394±0.022 mg (P>0.05) and in purified propolis extract – 0.427±0.044 mg and 0.256±0.02 mg (P>0.05). Klebsiella pneumoniae is most resistant to soft propolis extract when the concentration of phenolic compounds is 1.119± 0.152 mg and to purified propolis extract when the concentration of phenolic compounds is 1.013±0.189 mg (P>0.05). Spore-forming Bacillus subtilis bacteria are more sensitive to soft and purified propolis extracts when the concentration of phenolic compounds is 0.134±0.002 mg and 0.075±0.025 mg, respectively, and Bacillus cereus – when the concentration is 0.394±0.022 mg and 0.256±0.02 mg (P>0.05). Sensitivity of fungus Candida albicans to soft and purified propolis extracts is the same as Bacillus subtilis. Encapsulated bacterium Klebsiella pneumoniae is most resistant to antimicrobial action of soft and purified propolis extracts as compared with gram-positive Staphylococcus aureus and Enterococcus faecalis bacteria (P<0.05), gram-negative Escherichia coli, Pseudomonas aeruginosa, and Proteus mirabilis (P<0.05), sporeforming Bacillus subtilis and Bacillus cereus bacteria (P<0.05), and fungus Candida albicans (P<0.05). There is no statistically significant difference between antimicrobial effect of soft propolis extract and purified propolis extract on gram-positive bacteria, gram-negative bacteria, spore-forming bacteria, encapsulated bacteria, and Candida fungus. Conclusions. Soft and purified propolis extracts possess antimicrobial activity. They could be recommended as natural preservatives in the manufacture of pharmaceutical products.

A wide range of medicinal plant extracts has phytochemicals that possess antimicrobial properties and these plants are used to treat several infections. The study aimed to assess the antimicrobial activities of some spices extracts and to evaluate the phytochemicals present in them. The extracts of spices were prepared using Soxhlet apparatus refluxing with methanol and ethanol. The well diffusion technique was implemented for the evaluation of antimicrobial activities of the extracts and the zone of inhibitions was recorded in millimeters. The antimicrobial test was done against five bacterial isolates: Escherichia coli, Proteus mirabilis, Pseudomonas aeruginosa, Salmonella enterica serotype Typhi, and Staphylococcus aureus and a fungal isolate: Candida albicans. The extracts were concentrated by Rotary Vacuum Evaporator and a stock solution of 200 mg/mL was prepared by dissolving in 10 % DMSO. Concentrations of 40, 60, 80 and 100 mg/mL extracts were used for antimicrobial activity. The result of this study showed that clove extracts had the highest antimicrobial property against all the test microorganisms. Methanolic extract of clove had the highest inhibitory effect against Proteus mirabilis (24.21±0.15 mm), Pseudomonas aeruginosa (19.78±0.23 mm), and Candida albicans (20.07±0.08 mm) whereas ethanolic extract was effective against Escherichia coli (20.44±0.16 mm), Salmonella Typhi (21.66±0.31 mm) and Candida albicans (21.11±0.09 mm). Cinnamon and pepper extracts, leaving some exceptions, also had antimicrobial properties. The presence of phytochemicals: polyphenols, flavonoids, and tannins are the major components responsible for antimicrobial activity. Thereby, this study successfully demonstrated the possibilities of using spices extracts in the treatment of microbial infections.

Abstract. This research aimed to determine the antimicrobial activity of ethanol extract of Petiveria alliacea stem (EEPS) against Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli, and Candida albicans. The minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) were determined by perforation and broth micro dilution methods. Study on the mechanism of action of EEPS was conducted by molecular docking and Scanning Electron Microscopy (SEM) techniques. The results showed that EEPS had an inhibitory activity against Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli and Candida albicans with MIC values of 256, 128, 256, 512 µg/ml, consecutively. These values are included in to the medium category. Through the process of molecular docking, the best interaction was observed between S-benzyl-L-cysteine sulfoxide with penicillin-binding protein receptor of Pseudomonas aeruginosa characterized by free energy change (ΔG) of 4.32 kcal/mol, and the Ki value of 682.16 μM. Four folds of MIC of the EEPS caused changes in the morphology of Pseudomonas aeruginosa. EEPS possessed antimicrobial activities against Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli, and Candida albicans.   Keywords: Antimicrobial Activity, Molecular Docking, Petiveria alliacea, SEM.

Background: Due to the rapid development of microbial resistance, finding new molecules became urgent to counteract this problem. Objective: The objective of this work is to access 1,2,3-triazene-1,3-disubstituted, a class of molecule with high therapeutic potential. Methods: Here we describe the access to 17 new triazene including six with an imidazole-1,2,3-triazene moiety and eleven with an alkyl-1,2,3-triazene moiety and their evaluation against five strains: two gram (-): Escherichia coli ATCC 25921 and Pseudomonas aeruginosa ATCC 27253; two gram (+) : Staphylococcus aureus ATCC 38213 and Enterococcus faecalis ATCC 29212; and one fungi: Candida albicans ATCC 24433. Results: All strains were sensitive and the best MIC, 0.28 µM, is observed for 4c against Escherichia coli ATCC 25921. Compound 9, 3-isopropynyltriazene, appears to be the most interesting since it is active on the five evaluated strains with satisfactory MIC 0.32 µM against Escherichia coli and Pseudomonas aeruginosa and 0.64 µM against Enterococcus faecalis and Pseudomonas aeruginosa. Conclusion: Comparing the structure activity relationship, electron withdrawing groups appear to increase antimicrobial activity.

Background: Benzoic acid (BA) and salicylic acid (SA) combined are used as choice topical treatment for fungal and bacterial infections but their delivery is affected by ointment vehicle, among other factors. With aim to achieve improved release and antimicrobial activity in ointment formulation of these medicaments through selection of more efficient vehicle(s), this study comparatively evaluated prospective alternatives to thecompendium-specified base for delivery potential and relevant physical properties.Methodology: Water-sorption capacity, rheological characteristics and heat-tolerance limits of six hydrophilic bases [hydrous ointment (HO), hydrous sheabutter (HS), neat sheabutter (NS), lanolin anhydrous (LA), lanolin hydrous (LH), and emulsifying ointment (EO)] and their ointment products containing 1, 2, 3, or 6% w/w of BA or SA were determined. Drug delivery propensity of the products was evaluated by agar diffusion colorimetric assay, while their antimicrobial activities were determined by hole-in-plate agar diffusion assay against selected type organisms (Bacillus subtilis, Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Candida albicans and Candida pseudotropicalis).Results: BA was released in relatively larger quantity and demonstrated greater antimicrobial activity than SA in most bases. The released quantities of each medicament correlated directly with concentration and antimicrobial activities. The rates and extents of drug release followed a similar trend in different vehicles namely, HO > HS > NS ≥ EO > LA ≈ LH. Water number of base, ointment preparation method, viscosity, or heat-tolerance showed no influence on drug release or antimicrobial activity.Conclusion: HO and HS are better vehicles for delivery of BA and SA in ointment than EO which is the prototypical base. Keywords: Benzoic acid, Salicylic acid, Antimicrobial activity, Ointment base, Delivery factors French Title: Évaluation comparative des bases hydrophiles pour une meilleure administration d'acide benzoïque et d'acide salicylique dans une pommade antimicrobienne Contexte: L'acide benzoïque (BA) et l'acide salicylique (SA) combinés sont utilisés comme traitement topique de choix pour les infections fongiques et bactériennes, mais leur administration est affectée par le véhicule de la pommade, entre autres facteurs. Dans le but d'améliorer la libération et l'activité antimicrobienne dans la  formulation de pommade de ces médicaments grâce à la sélection de véhicules plus efficaces, cette étude a évalué comparativement des alternatives potentielles à la base spécifiée dans le compendium pour le potentiel d'administration et les propriétés physiques pertinentes.Méthodologie: Capacité de sorption de l'eau, caractéristiques rhéologiques et limites de tolérance à la chaleur de six bases hydrophiles [pommade hydratée (HO), beurre de karité hydraté (HS), beurre de karité pur (NS), lanoline anhydre (LA), lanoline hydratée (LH), et onguent émulsifiant (EO)] et leurs produits de pommade contenant 1, 2, 3 ou 6% p/p de BA ou SA ont été déterminés. La propension à l'administration de médicaments des produits a été évaluée par un essai colorimétrique de diffusion sur gélose, tandis que leurs activités antimicrobiennes ont été déterminées par un essai de diffusion sur gélose en plaque contre des organismes de type sélectionné (Bacillus subtilis, Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Candida albicans et Candida pseudotropicalis).Résultats: BA a été libéré en quantité relativement plus grande et a démontré une plus grande activité antimicrobienne que SA dans la plupart des bases. Les quantités libérées de chaque médicament étaient directement liées à la concentration et aux activités antimicrobiennes. Les taux et l'étendue de la libération de médicaments ont suivi une tendance similaire dans différents véhicules, à savoir HO> HS> NS ≥ EO> LA ≈ LH. Le nombre d'eau de base, la méthode de préparation de la pommade, la viscosité ou la tolérance à la chaleur n'ont montré aucune influence sur la libération du médicament ou l'activité antimicrobienne.Conclusion: HO et HS sont de meilleurs véhicules pour la livraison de BA et SA en onguent que EO qui est la base prototypique.
