Structural and theoretical exploration of a multi-methoxy chalcone: Synthesis, quantum theory, electrostatics, molecular packing, DFT analysis, and in-silico anti-cancer evaluation
Abstract
This study explores the pharmacological potential of chalcones through a multidisciplinary approach, including synthesis, quantum theory, molecular electrostatics, and density functional theory (DFT) calculations. The synthesized compound, analyzed via single crystal X-ray diffraction, crystallized in the triclinic system (space group P-1) with C–H⋯O interactions stabilizing its structure. Hirshfeld surface analysis confirms these interactions, with H–H contacts dominating (45.1 %). Molecular electrostatics analysis reveals charge distribution, and a 3.10 eV HOMO-LUMO energy gap indicates bioactivity. Molecular docking identifies the compound (3a) showed a maximum Gscore of HTNF-α (−9.81 kcal/mol); Tubulin (−7.96 kcal/mol); COX2 (−7.88 kcal/mol), EGFR (−6.72 kcal/mol), and VEGFR1(-2.50 kcal/mol). Where compound (3c) showed maximum binding at the putative binding site with dock scores for VEGFR2 (−9.24 kcal/mol). This research not only advances molecular science but also holds promise for diverse applications, including drug design. The significance of this study lies in its comprehensive exploration of the pharmacological potential of chalcones using a multidisciplinary approach. Through the integration of synthesis, quantum theory, molecular electrostatics, and density functional theory (DFT) calculations, we have extensively explored the structural and biochemical characteristics of these compounds. This investigation has revealed valuable insights that have the potential…
