Abstract

There are increasing number of reports on Candida albicans developing resistance to available anti-fungal drugs. Thus, there is an urgent need to discover new agents for treatment of candidiasis. The alcoholic extracts of Orthoshipon aristatus have been shown to exhibit antifungal activity against C. albicans by using the agar diffusion and broth microdilution methods. However, the underlying mechanisms of anti-C. albicans effect of O. aristatus have not been well understood. This study was aimed to evaluate the cytotoxic and anti-biofilm effects of the n-hexane and ethanol extracts of purple and white varieties of O. aristatus leaves and branches against C. albicans. The effect of n-hexane and ethanol extract against C. albicans growth was carried out by crystal violet viability assay. IC50 values of the most active extract, and nystatin and fluconazole as positive controls were also determined by the crystal violet assay. Evaluation of the anti-biofilm effect was performed by treating C. albicans with the extracts at adhesion, development, and biofilm maturation stages using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. The n-hexane extract of the purple variety of O. aristatus leaves demonstrated the strongest cytotoxic activity against C. albicans amongst the tested extracts, with an IC50 value of 0.67 µg/mL. The extract also showed strong anti-biofilm effect as fluconazole, with pronounced inhibition at the adhesion stage and less activity at the biofilm development and maturation stages. These results suggested that the n-hexane extract of the purple variety of O. aristatus leaves could be explored for discovery and development of anti-C. albicans agent.

Abstract

This study aims to prove the ability of crude cellulase enzymes from snails for protoplasting Aspergillus oryzae cells and its application for strain improvement with UV mutagenesis. Snail enzyme was obtained from Achatina fulica by dissolving its digestion track and fractionating it with ammonium sulfate. The activity of fractions was measured Spectrophotometrically and used for cell protoplasting for 2 hours, then irradiated with UV for 10, 15, and 20 minutes, respectively, with 5 cm in the distance. Screening of mutants is carried out with 1% FeCl3, and the potential mutant strain was tested for kojic acid production in an aerobic state and determined by Spectrophotometry at 268 nm. The cellulase activity in crude snail enzyme was 11.5807 U/ml and increased to 16.3984 U/ml after fractionation. The best protoplast formation was obtained with a 60% fraction, which showed transparent performance under the microscope. The UV mutagenesis of protoplasts showed that the highest number of potential mutants was obtained from UV treatment for 15 minutes (41.67%). The potential mutants look dark brown (DBC), such as strain 10H3, and produced higher kojic acid concentration than the parent strain. In conclusion, UV mutagenesis of Aspergillus oryzae through protoplasting by crude cellulase of snail enzyme was effective and improved kojic acid concentration.

Abstract

Recent advances in biotechnology have sparked global interest in developing biosimilar drugs, particularly those containing physiologically active proteins, such as growth factors and cytokines. The methylotrophic yeast Pichia pastoris can produce and secrete fully active heterologous proteins with strong secretory capacity and low levels of native proteins and has the ability to achieve high cell densities. In this study, a yeast‐based system was used to express and purify recombinant human granulocyte colony‐stimulating factor (rG‐CSF). Cultures were induced every 12 h for 48 h to express rG‐CSF, and parameters such as cell density, media pH, and cell dry weight were observed. Cell density increased along with the corresponding secretion of rG‐CSF during the induction period, as determined by Western blot assay, while the pH of the media remained stable. Ammonium sulfate at different saturation levels was used to precipitate the recombinant protein, with the highest total protein content determined spectrophotometrically at 29.6 µg/mL. Ni‐NTA resin with affinity column purification was used to purify the recombinant protein. The purified protein showed rG‐CSF with a molecular weight of approximately 18 kDa based on SDS‐PAGE analysis and immuno slot blot assay detected in purple. Overall, the study results indicated that the production and purification of rG‐CSF was successful, although optimization was required. The long‐term goal of this research is to discover alternative methods and sources for producing biosimilars of the therapeutic protein rG‐CSF, which can be utilized in the pharmaceutical industry to support health programs, particularly cancer treatment.

Abstract

Typhoid fever caused by Salmonella typhi remains a serious health threat. Although standard treatment with antibiotics such as chloramphenicol has helped reduce mortality rates, bacterial resistance to this antibiotic is increasing. New treatment approaches are urgently needed, including combining antibiotics with natural compounds from medicinal plants, such as Andrographis paniculata and Curcuma domestica. This study aimed to compare the antibacterial effects of A. paniculata extract, C. domestica extract, chloramphenicol, and their combinations on the growth of S. typhi. This in vitro experimental study used the disc diffusion method to evaluate antibacterial activity. Antibacterial activity tests were performed against S. typhi using discs soaked in 70% ethanol extract solutions of A. paniculata and C. domestica, chloramphenicol, and their combinations. Inhibition zones were measured after incubation for 24 hours at 37°C. Chloramphenicol showed the strongest antibacterial activity with a mean inhibition zone of 28.33 ± 0.58 mm. Single extracts of A. paniculata and C. domestica had relatively weak antibacterial activity (inhibition zones of 9.67 ± 1.15 mm and 9.83 ± 0.29 mm) and there was no significant difference between them (p>0.05). Combinations of extracts with chloramphenicol showed increased antibacterial activity compared to single extracts (inhibition zones of 23.17 ± 1.26 mm for A. paniculata + chloramphenicol and 21.00 ± 2.65 mm for C. domestica + chloramphenicol) and there were significant differences between combinations and single extracts (p<0.05), but still lower than single chloramphenicol and statistically significant (p<0.05). Although combining medicinal plant extracts with chloramphenicol increased antibacterial activity compared to single extracts, it did not exceed single chloramphenicol.

Abstract

?-Amino alkohol merupakan senyawa organik yang mengandung gugus amino dan hidroksil pada posisi ? terhadap satu sama lain, dan diketahui memiliki potensi sebagai agen antibakteri. Permasalahan utama dalam penelitian ini adalah terbatasnya informasi sistematis mengenai hubungan struktur-aktivitas senyawa turunan ?-amino alkohol dan metode sintesis optimal untuk menghasilkan senyawa dengan aktivitas antibakteri yang tinggi. Tujuan kajian ini adalah untuk menganalisis berbagai metode sintesis turunan ?-amino alkohol, mengevaluasi potensi aktivitas antibakteri berdasarkan parameter zona hambat dan konsentrasi hambat minimum (KHM), serta mengidentifikasi hubungan struktur-aktivitas untuk pengembangan kandidat antibakteri baru. Metode penelitian menggunakan systematic review dengan pendekatan PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analysis) melalui pencarian literatur pada basis data Perpustakaan Online Universitas Indonesia, Google Scholar, ScienceDirect, Scopus, PubMed, Wiley Journal, dan The Royal Society of Chemistry menggunakan kata kunci "synthesis of ?-amino alcohol", "?-amino alcohol", "antimicrobial", "antibacterial", dan "?-amino alcohol derivatives". Dari 244 artikel yang ditemukan, 4 artikel memenuhi kriteria inklusi dan mengevaluasi aktivitas antibakteri senyawa hasil sintesis. Hasil kajian menunjukkan bahwa sintesis turunan ?-amino alkohol dapat dilakukan melalui berbagai metode seperti pembukaan cincin epoksida, reaksi Mannich, pembentukan basa Schiff, dan reduksi asimetris dengan yield berkisar 68-96%. Senyawa dengan substituen seperti fenil piperazin, imidazol, serta gugus aromatik menunjukkan aktivitas signifikan terhadap bakteri Gram positif (S. aureus, B. subtilis) dan Gram negatif (E. coli, P. aeruginosa) dengan nilai KHM terendah 15,6 µg/mL pada senyawa 1-fenil-2-[(1-fenilpropil)amino]propan-1-ol terhadap Klebsiella pneumoniae. Implikasi penelitian ini menunjukkan bahwa desain struktur kimia yang tepat, terutama keberadaan sistem aromatik dan gugus donor elektron yang kuat, dapat meningkatkan potensi antibakteri senyawa turunan ?-amino alkohol dan mendukung pengembangan lebih lanjut sebagai kandidat antibakteri baru untuk mengatasi resistensi antimikroba.
