One of the primary purposes this study is to synthesize new aryl sulfonate-naphthalene hybrid structures possessing divergent electron-withdrawing and electron-releasing functional groups. Following improved reaction conditions, we successfully gathered ten distinct sulfonate derivatives (3a-j) with good yields. The synthesized naphthalene-based were then characterized using appropriate analytical methods (FT-IR, 1H-NMR, 13C-NMR, HRMS, elemental analysis). Additionally, in vitro silico enzyme inhibitory properties prepared evaluated against pancreatic lipase tyrosinase enzymes. Corresponding activity investigations revealed that produced compounds inhibit enzymes significantly. According lowest IC50 values, 3h (95.3 ± 4.0 µM) demonstrated most effective inhibition lipase, whereas 3a (40.8 3.3 was found as tyrosinase. studies, exhibited highest affinity value (-9.9 kcal/mol) 3f best (-8.7 tyrosinase.Furthermore, investigated various structural physicochemical target molecules, namely frontier orbital' (HOMO, LUMO, bandgap) energies (including their corresponding contour plots), global reactivity descriptors (ionization energy electron affinity), electronegativity values from ground-state (GS) density theory (DFT) calculations. These observed electrostatic interactions effectively contributed studied molecules' experimentally potential. Also, ADMET studies enlighten molecular enzymes.Communicated by Ramaswamy H. Sarma.
