A Series Of Biguanide Ligands and Their Cu(II) Complexes: Cholinesterase Inhibitory And Antimicrobial Properties
Chem Biodivers. 2023 Dec 15:e202301434. doi: 10.1002/cbdv.202301434. Online ahead of print.ABSTRACTIn this work, a series of biguanide hydrochloride salts and their Cu(II) complexes were synthesized and screened for their acetyl/butyryl choline esterase inhibitory and antimicrobial properties. The structures of the synthesized compounds were characterised by common spectroscopic and analytical methods. Biguanide compounds showed considerably lower inhibitory activity compared to the reference drugs donepezil and galantamine. On the other hand, complexation of the biguanide compounds with Cu(II) resulted in dramatic increas...

Nanoplasmonic biosensors for multicolor visual analysis of acetylcholinesterase activity and drug inhibitor screening in point-of-care testing
Biosens Bioelectron. 2023 Dec 8;247:115912. doi: 10.1016/j.bios.2023.115912. Online ahead of print.ABSTRACTThe monitoring of acetylcholinesterase (AChE) activity and the screening of its inhibitors are significance of the diagnosis and drug therapy of nervous diseases. A metal ions-mediated signal amplification strategy was developed for the highly sensitive and multicolor assay of AChE activity and visually screening its drug inhibitors. After the specific reaction between AChE and acetylthiocholine (ATCh), the hydrolysis product thiocholine (TCh) can directly and decompose the α-FeOOH nanorods (NRs) to release amounts o...

Design, synthesis, and biological evaluation of novel donepezil-tacrine hybrids as multi-functional agents with low neurotoxicity against Alzheimer's disease
In this study, the target compounds were evaluated for their ability to inhibit AChE and butyrylcholinesterase (BuChE) in vitro, using tacrine (hAChE, IC50 = 305.78 nM; hBuChE, IC50 = 56.72 nM) and donepezil (hAChE, IC50 = 89.32 nM; hBuChE, IC50 = 9137.16 nM) as positive controls. Compound B19 exhibited an excellent and balanced inhibitory potency against AChE (IC50 = 30.68 nM) and BuChE (IC50 = 124.57 nM). The cytotoxicity assays demonstrated that the PC12 cell viability rates of compound B19 (84.37 %) were close to that of tacrine (87.73 %) and donepezil (79.71 %). Potential therapeutic effects in AD were evaluated using...

Characterization of Potentially Inappropriate Medications That Need Special Attention in the Elderly with Dementia by Analyzing Pharmacy Claims Data
Biol Pharm Bull. 2023;46(12):1699-1705. doi: 10.1248/bpb.b23-00385.ABSTRACTCommunity pharmacists may play a key role in promoting deprescribing of potential inappropriate medications (PIMs) that are highly prevalent among community-dwelling elderly with dementia. To characterize PIMs categories that need a special attention for dementia patients, in the present study, we analyzed the anonymized pharmacy claims data of patients aged 65 years and older (n = 333869) who visited nationwide 905 community-based pharmacies of Sugi Pharmacy Co., Ltd. during December 1-31, 2019. A dementia group was defined as patients who received...

EPH75 Adverse Event Types and Discontinuation Rate of Alzheimer's Medication Approved by United States Food and Drug Administration (USFDA)
Alzheimer's Disease and related dementia (ADRD) is a public health emergency affecting the aging population in the US. By 2023, 6.7 million Americans 65 and older are estimated to have Alzheimer's. Pharmacological management of Alzheimer's includes inhibition of acetylcholinesterase and N-methyl-D-aspartate receptors. AChEIs like donepezil, galantamine, and rivastigmine treat mild and severe AD. (Source: Value in Health)
