In this particular context, a range of asymmetric biscarbothioamide derivatives (3a-l) with varying substitutions have been meticulously designed and effectively synthesized. The newly synthesized compounds have all been definitively characterized using established spectroscopic techniques such as 1H-NMR, 13C-NMR, FT-IR, and elemental analysis. In vitro, all the derivatives (3a-l) were evaluated to assess their inhibitory potential against cholinesterase enzymes (acetylcholinesterase, AChE, and butyrylcholinesterase, BChE). The outcomes demonstrated that these derivatives were potent and exhibited selectivity in inhibiting AChE, except for compounds 3b and 3e, which specifically inhibited BChE, showcasing varying degrees of KI values. Significantly, compounds 3j (KIs of 11.91 +/- 2.25 nM for AChE and 77.76 +/- 8.02 nM for BChE) and 3h (KIs of 14.73 +/- 2.30 nM for AChE and 59.54 +/- 6.20 nM for BChE) emerged as the most potent dual inhibitors of AChE and BChE within the series, respectively, with KI constants even lower than those of the standard drug tacrine (KIs of 68.70 +/- 5.39 nM for AChE and 111.60 +/- 10.52 nM for BChE). Furthermore, their potential scavenging activity against DPPH and ABTS radicals was evaluated. To further validate the experimental findings, molecular docking studies were performed in silico to ascertain the binding modes of these compounds with the active pockets of AChE and BChE enzymes. Investigating innovative frameworks for addressing Alzheimer's disease is a challenging goal. In this specific scenario, a selection of asymmetric biscarbothioamide derivatives (3a-l) with different substitutions has been carefully formulated and successfully synthesized.eninfo:eu-repo/semantics/closedAccessArticle10.1039/d4nj01462f0012374481000011369-9261
