Abstract

SARS-CoV-2 is a new strain of coronavirus (CoV) that was identified in Wuhan in 2019. This virus is known to have the ability to reduce human immunity. Kelor (Moringa oleifera) is a potential natural resource in Indonesia, which is very abundant and contains several metabolic compounds such as phenolics, flavonoids, saponins, cytokines, and caffeoylquinic acid, which was reported to show antioxidants, antibacterial and antiviral. This study aims to predict the biological activity, physicochemical properties, toxicity, and affinity-interactions of the active compounds of M. oleifera leave. The active compounds of M. oleifera were obtained from the KNApSAcK and PubChem. Analysis of the bioactivity of the compounds using the Way2Drug Pass Online. Analysis of drug-likeness and toxicity using the Lipinski web server and pkCSM. Docking is done using Autodock vina software to analyze the interaction of the compounds with Mpro. The results indicate that the compound astragalin is the compound with the highest affinity value, namely -8.7 (kcal/mol), compared to lopinavir as a control compound with an affinity value -6.6 (kcal/mol). The types of bonds in astragalin compounds are hydrogen bonds with amino acids Glutamine 127 and Arginine 298. From these results, it is predicted that astragalin compounds have the highest potential as alternative drugs to increase body immunity against the COVID-19.

Abstract

Simian Immunodeficiency Viruses (SIV) have been found to naturally infect African nonhuman primates (NHP). This causative agents are important and one of the special interest as the root cause of the HIV/AIDS pandemic, one of the most threatening infectious diseases worldwide. The aim of this study was to design an epitope-based vaccine using bioinformatics approaches of the circulating SIV in Kenya, Africa. In this study, we used 17 partial SIV envelope glycoprotein genes retrieved from GenBank® (National Center for Biotechnology Information, USA). We analysed the candidate epitopes using the Immune Epitope Database and Analysis Resource. Then, we performed the protective antigens prediction usingVaxiJen. Interestingly, this study revealed the data of B cell epitope prediction, protective antigens prediction, and molecular phylogenetic of circulating SIV in Kenya, Africa. In sum, this study can be used to design a novel epitope-based vaccine against SIV. We suggest further studies to conduct confirmatory experiments (in vitro and in vivo).

Abstract

SARS-2 infection is predicted to trigger DNA damage due to excessive inflammatory responses from the immune system such as cytokine storms. The cytokine storm leads to an increase in oxidative stress in cells, possibly triggering senescence through activation of the DNA damage response (DDR) signaling pathway. Alterations in the DDR pathway that induce cellular senescence have been identified due to the regulation of viral proteins that lead to impaired DNA repair. However, previous studies have not examined the relationship between DNA damage, inflammation, and cellular senescence. In this short review, we will discuss with a simple perspective why SARS-CoV-2 infection can accelerate the cellular senescence process and its relationship with the inflammatory response.

Abstract

The monkeypox virus (MPXV), a DNA virus causing zoonotic disease, poses major global public health challenges, with mortality rates between 3%–6%. Although smallpox vaccines provide partial cross-protection, there is a critical need for a dedicated, effective monkeypox (mpox) vaccine. This study aimed to design a multi-epitope peptide-based vaccine specifically adapted to the HLA allele profiles common in Southeast Asian populations, where MPXV cases are rising. Using immunoinformatics, we screened for and detected B and T cell epitopes from the MPXV cell surface antigen and IFN-alpha/beta receptor proteins. The vaccine design was validated through a rigorous evaluation of its antigenicity, immunogenicity, allergenicity, and toxicity to ensure both safety and efficacy. Key epitopes were mapped to HLA alleles including HLA-A*11:01, HLA-A*24:02, and HLA-B*15:02, which are highly prevalent in Southeast Asia populations. Molecular docking analyses demonstrated stable interactions between the vaccine construct and TLR3/TLR4 immune receptors, suggesting a robust immune response activation. Additionally, molecular dynamics simulations confirmed the structural stability of the vaccine-receptor complex. This immunoinformatics-driven multi-epitope vaccine design offers a promising candidate for combating MPXV, with high projected coverage and immuno-genic potential for Southeast Asian populations. Validation in laboratory and clinical settings is recommended to con-firm these findings.

Abstract

This research focuses on an innovative approach utilizing in silico methods to design small interfering RNA (siRNA) targeting the HER2 splice variant mRNA in Homo sapiens. HER2 is known to be overexpressed in certain types of breast cancer, contributing to tumor progression and poor prognosis. By designing siRNA molecules that can specifically bind to and degrade HER2 mRNA, this study aims to reduce HER2 protein levels, thereby hindering the growth and spread of breast cancer cells. The in-silico design process involves identifying optimal siRNA sequences that maximize target specificity and minimize off-target effects, which is crucial for potential therapeutic applications. This approach represents a promising step towards personalized medicine in the treatment of breast cancer, offering a targeted strategy to combat this variant associated with aggressive disease. The methodology comprises the RNA computational tools used for the design, the selection criteria for siRNA candidates, and the potential implications of this research in a clinical setting. The resulting outcomes are 2D and 3D siRNA designs that could potentially silence HER2 mRNA through an in-silico approach. The leads were generated using a de novo modeling approach, with no existing template available in GenBank. Moreover, it is concluded that computational tools can generate sufficiently stable 2D and 3D RNA models that could be advanced for further molecular simulation studies. The benefit of this outcome is that it facilitates better preparation for wet laboratory experiments in siRNA assays, with future implementation in vivo and clinical trial settings.

Abstract

Breast cancer remains one of the leading causes of cancer-related mortality worldwide, suggesting the need for novel therapeutic agents with greater efficacy and fewer side effects. Brazilin, a natural flavonoid compound isolated from Caesalpinia sappan L., has shown promising anticancer activity, particularly against breast cancer cells. This study explores the therapeutic potential of brazilin by evaluating its interactions with three key molecular targets: estrogen receptor alpha (ERα), 17β-hydroxysteroid dehydrogenase 1 (17β-HSD1), and Nudix hydrolase 5 (NUDT5). Using molecular dynamics (MD) simulations, the study assesses the stability and binding interactions of complex systems. The results indicate that brazilin forms a stable complex with ERα, demonstrated by a low RMSD (2.6 Å) and strong hydrogen bonding with Glu353, occupancies of 97.8%, and minimal flexibility at the binding site (average RMSF < 2.5 Å). The binding free energy (ΔG Total) for the ERα–brazilin complex was -54.28 kcal/mol, indicating a stronger affinity than the reference ligand 4-hydroxytamoxifen. Brazilin also showed favorable binding with 17β-HSD1 and NUDT5, with binding energies of -39.71 kcal/mol and -23.23 kcal/mol, respectively. These findings suggest that brazilin may modulate critical targets involved in breast cancer progression, particularly in hormone receptor-positive subtypes. Further experimental validation is necessary to confirm its efficacy and optimize its therapeutic potential.
