Background: Cellular senescence, characterized by irreversible cell cycle arrest, contributes significantly to the pathogenesis of cardiovascular diseases through mechanisms involving oxidative stress and activation of p53-mediated signaling. Moringa oleifera, widely recognized for its antioxidant properties, has demonstrated anti-aging effects; however, the specific bioactive compounds within its fruit and their mechanisms of action remain poorly understood. Objective: This study aimed to investigate the potential of M. oleifera fruit-derived compounds as anti-premature senescence agents targeting the p53 protein using in-silico molecular docking approaches. Methods: Bioactive compounds from M. oleifera fruit were screened via molecular docking against the human p53 protein, with Nutlin-3 used as a positive control. Binding affinities, hydrogen bonding, and hydrophobic interactions were analyzed to determine ligand{\textendash} receptor interactions. Results: Niacin and oxalic acid exhibited stronger binding affinities ({\textendash}5.90 and {\textendash}6.00 kcal/mol, respectively) compared to Nutlin-3 ({\textendash}5.64 kcal/mol). Niacin formed stable hydrogen bonds and hydrophobic interactions with key residues within the p53 active site, suggesting a capacity to modulate p53 activity. Oxalic acid demonstrated the highest binding affinity but lacked hydrogen bonding, indicating potential instability despite strong interaction. These findings support previous studies highlighting M. oleifera{\textquoteright}s role in ROS suppression and p53 modulation, pointing to its therapeutic relevance in mitigating cellular aging. Conclusion: Niacin and oxalic acid from M. oleifera exhibit promising binding characteristics as modulators of the p53 pathway. Their anti-senescence potential warrants further validation through molecular dynamics simulations and biological assays. This study supports the development of natural compound-based therapeutics for age-related cardiac degeneration.

Dengue is a major public health threat worldwide, affecting approximately 3 billion people. More than 100 countries in the world located in tropical and subtropical areas, there are at least 100 to 400 million people infected with the dengue virus which causes dengue hemorrhagic fever (DHF). Soluble Non Structural Protein (sNS1) DENV is a soluble NS1 protein that is secreted and found in the serum of patients during acute infection. Because of its presence early in infection, sNS1 is used as a diagnostic indicator of acute dengue infection. NS1 can directly activate platelets through TLR4 and can further increase platelet aggregation, endothelial cell adhesion, and phagocytosis by macrophages that can cause thrombocytopenia so that high sNS1 levels are associated with disease severity. From the results of the study showed p \<0.05. This indicates that there is a correlation between the presence of NS1 and the severity of dengue infection.
