Multiple studies have been recorded on the synthesis and design of multi‐aim anti‐Alzheimer molecules. Using dual butyrylcholinesterase/acetylcholinesterase inhibitor molecules has attracted more interest in the therapy for Alzheimer’s disease. In this study, a tannic acid compound showed excellent inhibitory effects against acetylcholine esterase (AChE), α‐glycosidase, α‐amylase, and butyrylcholinesterase (BChE). IC50 values of tannic acid obtained 11.9 nM against α‐glycosidase and 3.3 nM against α‐amylase, respectively. In contrast, Ki values were found of 50.96 ± 2.18 μM against AChE and 53.17 ± 4.47 μM against BChE. α‐Glycosidase inhibitor compounds can be utilized as a novel group of antidiabetic drugs. By competitively decreasing glycosidase activity, these inhibitor molecules help to hamper the fast breakdown of sugar molecules and thereby control the blood sugar level.
