Cytokine storm, also referred to as cytokine release syndrome (CRS), is a condition characterized by an excessive production of inflammatory signals by the immune system, potentially leading to organ failure and death. This phenomenon has garnered significant attention due to its association with the COVID-19 pandemic, wherein it appears to contribute to severe symptoms in certain individuals infected with the SARS-CoV-2 virus. In efforts to combat cytokine storm, researchers have explored natural substances as potential therapeutics. In this particular study, we investigated the efficacy of cholecalciferol in targeting key cytokines involved in cytokine storm. Through molecular docking analyses, molecular dynamics simulations, and assessment of pharmacokinetic properties, we evaluated the stability and potential of cholecalciferol in mitigating cytokine storm. Our findings indicate that cholecalciferol exhibits strong binding affinity with several cytokines, with binding energies exceeding −6.5 kcal/mol. Furthermore, post-molecular dynamics analysis revealed remarkable stability of cholecalciferol with these cytokines. Pharmacokinetic measurements further supported its potential as a therapeutic agent, demonstrating favorable characteristics in terms of absorption, distribution, metabolism, and excretion. This research suggests that cholecalciferol may hold promise in reducing cytokine storm and alleviating severe symptoms associated with conditions such as COVID-19.
