Abstract
Alzheimer's disease (AD) is a multifactorial and emerging neurological disorder, which has invoked researchers to develop multitargeted ligands. Herein, hybrid conjugates of 5-phenyl-1,3,4-oxadiazole and piperazines were rationally designed, synthesized, and pharmacologically evaluated against hAChE, hBChE, and hBACE-1 enzymes for the management of AD. Among the series, compound 5AD comprising pyridyl substitution at terminal nitrogen of piperazine contemplated as a paramount lead compound (hAChE, IC50 = 0.103 ± 0.0172 μM, hBChE, IC50 ≥ 10 μM, and hBACE-1, IC50 = 1.342 ± 0.078 μM). Compound 5AD showed mixed-type enzyme inhibition in enzyme kinetic studies against the hAChE enzyme. In addition, compound 5AD revealed a significant displacement of propidium iodide from the peripheral anionic site (PAS) of hAChE and excellent blood-brain barrier (BBB) permeability in a parallel artificial membrane permeation assay (PAMPA). Besides, 5AD also exhibited anti-Aβ aggregation activity in self- and AChE-induced thioflavin T assay. Further, compound 5AD has shown significant improvement in learning and memory (p < 0.001) against the in vivo scopolamine-induced cognitive dysfunction mice model. The ex vivo study implied that after treatment with compound 5AD, there was a decrease in AChE and malonaldehyde (MDA) levels with an increase in catalase (CAT, oxidative biomarkers) in the hippocampal brain homogenate. Hence, compound 5AD could be regarded as a lead compound and further be explored in the treatment of AD.

Discovery of blood-brain barrier permeable and orally bioavailable caffeine-based amide derivatives as acetylcholinesterase inhibitors. Bioorg Chem 2023; 139:106719.

Abstract
Caffeine is one of the privileged natural products that shows numerous effects on the central nervous system. Herein, thirty-one caffeine-based amide derivatives were synthesized and evaluated in vitro for their anticholinesterase activity. The introduction of the amide group to the caffeine core augmented its anticholinesterase activity from an IC50 value of 128 to 1.32 µM (derivative, 6i). The SAR study revealed that N7 substitution on caffeine core is favorable over N1, and the presence of amide 'carbonyl' as a part of the linker contributes to the biological activity. The caffeine core of 6i exhibits interactions with the peripheral anionic site, whereas the N-benzyl ring fits nicely inside the catalytic anionic site. Analog 6i inhibits AChE in a mixed-type mode (Ki 4.58 µM) and crosses the BBB in an in-vitro PAMPA assay. Compound 6i has a descent metabolic stability in MLM (>70% remaining after 30 min) and favorable oral pharmacokinetics in Swiss albino mice.

Abstract
In this study, the synthesis of new monostyryl (BDPY-2) and distyryl BODIPY dyes (BDPY-4, BDPY-5) containing pyridine groups has been reported for the first time. The acetylcholinesterase from Electrophorus electricus (AChE), butyrylcholinesterase from equine serum (BuChE), α-glucosidase from Saccharomyces cerevisiae and DNA hydrolytic cleavage actions of BDPY-2, BDPY-4, BDPY-5 were investigated using various techniques. The results indicated that the compounds had varying inhibition properties against AChE, BuChE, and α-glucosidase. BDPY-4 was the most potent compound on AChE with IC50 of 54.78 ± 4.51 µM, and Lineweaver-Burk plots indicated that the compound is bound to a site other than the active site as a noncompetitive inhibitor. The compound-protein binding experiment showed that BDPY-4 changed the microenvironment around AChE. On the other hand, the compounds showed lower α-glucosidase inhibition than the positive control. The DNA hydrolytic cleavage effects were not observed on supercoiled plasmid DNA in the presence of the compounds as compared to negative controls. These findings suggested that BDPY-4 might be a promising compound to treat Alzheimer's diseases.

Abstract
Among 276 herbal extracts, a methanol extract of Castanopsis cuspidata var. sieboldii stems was selected as an experimental source for novel acetylcholinesterase (AChE) inhibitors. Five compounds were isolated from the extract by activity-guided screening, and their inhibitory activities against butyrylcholinesterase (BChE), monoamine oxidases (MAOs), and β-site amyloid precursor protein cleaving enzyme 1 (BACE-1) were also evaluated. Of these compounds, 4'-O-(α-L-rhamnopyranosyl)-3,3',4-tri-O-methylellagic acid (3) and 3,3',4-tri-O-methylellagic acid (4) effectively inhibited AChE with IC50 values of 10.1 and 10.7 µM, respectively. Ellagic acid (5) inhibited AChE (IC50 = 41.7 µM) less than 3 and 4. In addition, 3 effectively inhibited MAO-B (IC50 = 7.27 µM) followed by 5 (IC50 = 9.21 µM). All five compounds weakly inhibited BChE and BACE-1. Compounds 3, 4, and 5 reversibly and competitively inhibited AChE, and were slightly or non-toxic to MDCK cells. The binding energies of 3 and 4 (- 8.5 and - 9.2 kcal/mol, respectively) for AChE were greater than that of 5 (- 8.3 kcal/mol), and 3 and 4 formed a hydrogen bond with Tyr124 in AChE. These results suggest 3 is a dual-targeting inhibitor of AChE and MAO-B, and that these compounds should be viewed as potential therapeutics for the treatment of Alzheimer's disease.
