Abstract

An emerging coronavirus, SARS-CoV-2, is the causative agent for the ongoing pandemic of coronavirus disease 2019 (COVID-19), which has caused a worldwide social and economic disruption. Currently, no antiviral drugs with proven clinical efficacy, or vaccines for its prevention. Therefore, to combat the pandemic of this novel coronavirus, new effective treatments are urgently needed. In the process of traditional drug development, developing new drugs from scratch is a time- consuming process, requires high-investment, and is a high-risk process, which is impractical to face the immediate global challenge of the SARS-CoV-2 pandemic. Drug repurposing strategy is one of the effective ways to quickly find a therapeutic agent for COVID-19 Existing medicines, which already have been tested and proven safe in humans might work for COVID-19 offering a potentially faster approach for the disease management. Here, we review h the latest research progress in epidemiology, viral genome, and life cycles of SARS-CoV-2. Further, we describe and discuss some promising drugs repurposed to target SARS-CoV-2 that are being evaluated in clinical trials.

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

Major Depressive Disorder (MDD) is a chronic disorder characterized by at least a two-week-long major depressive episode. Selective Serotonin Reuptake Inhibitors (SSRIs) remain the primary prescribed antidepressants to treat MDD. However, SSRIs themselves are found to be ineffective in some individuals or may even lead to adverse side effects. These variable responses have been linked to the drug being metabolized by CYP2C19, which exhibited various polymorphisms. Understanding how gene polymorphism affects drug metabolism is essential since these insights can revolutionize clinical practice, allowing for more precise and personalized treatment approaches that optimize efficacy while minimizing side effects. This issue is particularly pertinent in Indonesia, where research in this area lags behind the pressing need for such studies. In this review, the impact of CYP2C19 polymorphism on the effectiveness of SSRI class drugs, namely citalopram, escitalopram, and sertraline, are explored. Nine relevant articles related to the topic have been studied in Japan, China, Turkey, Russia, Scandinavia, and Australia. The results concluded that CYP2C19 polymorphism can influence the metabolism of SSRIs (citalopram, escitalopram, and sertraline) due to its variability in enzyme activities, which includes both loss-of-function (*2, *3) and gain-of-function (*17) polymorphisms. Consequently, these genetic variations can lead to significant changes in drug efficacy and safety changes within individual patients. This review sheds light on the importance of considering genetic factors when prescribing SSRIs for MDD in the future treatment strategies.

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

According to Global Burden of Disease reported on 2019, about 1.53 million deaths caused by infectious diseases such as pneumonia and diarrhea. Triclosan is one of the active ingredient commonly used in antibacterial soap as one way to prevent the spread of infectious disease.. However, bacteria resistance against triclosan has been reported. Silver nanoparticles (AgNP) is an alternative antibacterial that potential to be used in liquid hand wash. However AgNp tend to aggregate during storage, thus stabilizer is needed This study aims to synthesize AgNP, formulate the liquid hand wash contain AgNP with polyvinil alcohol as stabilizer, and evaluate its effectiveness against Escherichia coli, Staphylococcus aureus, and Salmonella thypi. AgNP was prepared using the chemical reduction method between silver nitrate and sodium borohydride, followed by its characterization using UV-Vis spectrophotometer, TEM, PSA, and AAS. The physical characteristic of AgNp-liquid hand wash were also evaluated. Further, the antibacterial activity of AgNP-handwash was evaluated by phenol coefficient method. The peak of UV absorption spectrum of colloidal was found at 404.2 nm indicated the presence of AgNP. Ag content in AgNP colloidal was 38.405 mg/Kg ± 0,008. The spherical shape of AgNP was observed. The AgNP size was 65.1 nm with polydispersity index value of 0.543, and zeta potential value was -22.25 mV. The obtained AgNP-hand wash met the Indonesian standard criteria and was stable for 28 days. The best phenol coefficient value was obtained at formulation with addition of 30% AgNP (0.1 for S. typhi, 0.4 for E. coli, and 0.01 for S. aureus).

Abstract

Influenza A virus is one of the most common causes of respiratory disease in the world. Even though, vaccines and anti-influenza virus are become the first line for therapy, but the mutation ability of influenza virus is able to cause several outbreaks in the world. Silver nanoparticles (AgNP) have been proven to exhibit antiviral activity; however, the use of AgNP in pharmaceutical products is still limited. In this study, we aimed to formulate nasal spray containing AgNP, to evaluate its physicochemical properties, and its antiviral activity toward H5N1 influenza A virus. AgNP were synthesized using chemical reduction method with polyvinyl alcohol as stabilizer, and further prepared into nasal spray product. Physicochemical properties and anti-hemagglutination activity of nasal spray were further evaluated. The nasal spray contained different size of AgNP (less and more than 50 nm) showed physical stability after 28 days storage. However, Anti-influenza evaluation of nasal spray contained AgNP less than 50 nm exhibited better anti-hemagglutination activity against influenza A virus.
