Triazole Derivatives

Due to the medicinal importance of triazole derivatives, the antimicrobial property of three synthesized triazole derivatives were screened in vitro against some Gram positive and Gram negative pathogenic bacteria and some pathogenic fungi. In this study, three compounds 2-(5-mercapto-4-phenyl-4H-[1,2,4] triazole-3-yl]-cyclohexa- 1,5-dienol (S1), 2-[5-mercapto-4-(2-mercapto-phenyl)-4H- [1,2,4] triazole-3-yl]-phenol (S2) and 4-[3-(2-hydroxyphenyl)- 5-mercapto-[1,2,4] triazole-4-yl]-benzene sulfonamide (S3) have been synthesized. The minimum inhibitory concentration (MIC) and the minimum bactericidal concentration (MBC) were assessed by serial dilution technique. The compounds showed moderate antimicrobial activity against all the tested organisms and the results are comparable to standard antibiotic kanamycin. The MIC values of the compounds were found to be in the range of 16~64μg/ml. The low MIC and MBC values and high sensitivity of pathogenic microorganisms to the compounds led to conclude that the triazole derivatives have potential antimicrobial properties.

AGAINST STAPHYLOCOCCUS AUREUS IN VITROThe discovery of antimicrobials has been significantly important for current treatments and the future developments in the medical field. One of the challenges faced in the usage of antibiotics is the resistance imposed by the bacteria towards the antibiotics itself. An example of such bacteria that experiences thisresistance is Staphylococcus aureus. As a result, studies regarding alternatives of treatments, specifically those utilizing various plants that may potentially have antibacterial properties are conducted. Previous studies have already shown that date palms of the Ajwa variety, known as Phoenix dactylifera, contains several active compounds that are potential antioxidants and exhibit antibacterial properties. The Ajwa date palm has also been mentioned in several scriptures of the Al-Quran and Al-Hadits. The objective of this study was to understand the antibacterial properties of aquadest-extracted Phoenix dactylifera through the measurement of the area of the zone of inhibition, the minimum inhibitory concentration (MIC), and the minimum bactericidal concentration (MBC) of Staphylococcus aureus. This study involves the use of an experimental method, known as in vitro, and is also a descriptive observational study with a quantitative approach. The methodology used consists of the well diffusion method and the solid dilution method. This study was conducted at Laboratorium Terpadu Mikrobiologi Poltekkes Bandung. The results of this study show an average zone of inhibition of 5.87 mm which is categorized as medium, a minimum inhibitory concentration of 50%, and a minimum bactericidal concentration that is yet to be found. Based on statistical tests, the result of the diffusion method shows that the aquadest-extracted Phoenix dactylifera is influential in inhibiting the growth of the Staphylococcus aureus bacteria.

Antimicrobial resistance is a growing concern worldwide. The indiscriminate use of antibiotics for a period of time has led to the emergence of antibiotic resistance in pathogenic bacteria. The present study was designed to evaluate the antibacterial efficacy of fluoroquinolone drugs, ciprofloxacin, enrofloxacin, moxifloxacin, sparfloxacin, norfloxacin, pefloxacin and ofloxacin against avian Salmonella gallinarum bacterial biofilms. The study parameters, minimum inhibitory concentration (MIC), minimum bactericidal concentration (MBC) and biofilm elimination concentration (BEC) were determined on days 1, 3, 7, 10, 14 and 20 post inoculation for the planktonic (free) and biofilm cells of S. gallinarum by macro broth dilution method. The MIC and MBC values determined on days 1, 3, 7, 10, 14 and 20 for each of the fluoroquinolone drugs against the planktonic and biofilm forms of avian S. gallinarum were found to be non-significant. BEC values determined against the biofilm forms of S. gallinarum during the study period were found to be non-significant among the tested fluoroquinolones. The results of the present study demonstrated that fluoroquinolone drugs were effective in vitro against both the planktonic and biofilm forms of avian S. gallinarum.

Rattlesnakes have venoms with a complex toxin mixture comprised of polypeptides and proteins. Previous studies have shown that some of these polypeptides are of high value for the development of new medical treatments. The aim of the present study is to evaluate, in vitro, the antibacterial and hemolytic activity of Crotalus triseriatus and Crotalus ravus venoms. A direct field search was conducted to obtain Crotalus triseriatus and Crotalus ravus venom samples. These were evaluated to determine their antibacterial activity against Escherichia coli, Staphylococcus aureus and Pseudomonas aeruginosa through the techniques of Minimum Inhibitory Concentration (MIC) and Minimum Bactericidal Concentration (MBC). Hemolytic activity was also determined. Antibacterial activity was determined for treatments (Crotalus triseriatus 2) CT2 and (Crotalus ravus 3) CR3, obtaining a Minimum Inhibitory Concentration of 50 µg/mL and a Minimum Bactericidal Concentration of 100 µg/mL against Pseudomonas aeruginosa. CT1 (Crotalus triseriatus 1), CT2, and CR3 presented hemolytic activity; on the other hand, Crotalus ravus 4 (CR4) did not show hemolytic activity. The results of the present study indicate for the first time that Crotalus triseriatus and Crotalus ravus venoms contain some bioactive compounds with bactericidal activity against Pseudomonas aeruginosa which could be used as alternative treatment in diseases caused by this pathogenic bacterium.
