Abdellattif,  c Amit Dubey  *d and Rakesh Kumar Sinha*a  \nHeatstroke-induced multiorgan dysfunction represents a life-threatening clinical emergency characterized by systemic oxidative stress, inflammation, and metabolic collapse across vital organs. Despite advances in supportive care, there remains a critical lack of multitarget pharmacological interventions that address the underlying molecular pathology. Here, we evaluated baicalin, a naturally occurring flavone glycoside, for its multiorgan protective efficacy against systemic hyperthermia through an integrated computationalexperimental framework. Five key heat-responsive proteins—heat shock protein 70 (Hsp70), heat shock protein 27 (Hsp27), aquaporin-1 (AQP1), interleukin-6 receptor (IL-6R), and cytochrome P450 3A4 (CYP3A4)—were identified as therapeutic targets based on their roles in heat-induced stress and organ injury. Molecular docking revealed strong binding affinities (DG = −9 .3 to −8 .5 kcal mol−1), supported by molecular dynamics (MD) simulations (2000 ns) showing conformational stability (root mean square deviation, RMSD \u003C 0.25 nm; 5–8 hydrogen bonds) and favorable molecular mechanics–generalized born surface area (MM-GBSA) binding energies (up to −65 .3 kcal mol−1 for Hsp70-baicalin) . Principal component analysis (PCA) and free energy landscape (FEL) mapping confirmed thermodynamic stability, while density functional theory (DFT) calculations (highest occupied molecular orbital-lowest unoccupied molecular orbital, HOMO–LUMO gap = 3.45 eV) supported baicalin's electronic reactivity. In vivo validation using a rat whole-body hyperthermia model (42 ± 0.5 °C for 4 h) demonstrated significant attenuation of heat-induced pathology. Histopathological scoring revealed reduced lesion severity in the brain, heart, kidneys, liver, and lungs following baicalin pre-treatment (50 mg kg−1, intraperitoneal) . Western blot and densitometric analyses confirmed downregulation of Hsp70, Hsp27, and IL-6R alongside restoration of CYP3A4 (p \u003C 0 .05) . Complementary absorption, distribution, metabolism, excretion, and toxicity (ADMET) and ProTox-II analyses predicted a high safety margin (LD50 z 5000 mg kg−1; non-hepatotoxic; nonmutagenic) . Collectively, these findings establish baicalin as a promising multitarget natural cytoprotective agent and underscore the translational potential of combining computational pharmacology with in vivo disease modeling to accelerate cytoprotective drug discovery.  \n1.
