13. Current Approaches Against Alzheimer's Disease in Clinical Trials
Alzheimer's disease (AD) is a progressive degenerative brain disease which causes mental and physical decline, gradually resulting in death. Currently, this disease represents one of the uppermost human issues, both from the medical and economic point of view. Interest in the discovery of a drug for AD is enormous. However, despite the long-term and worldwid

14. Effect of Organic Solvent Composition on Dissociation Constants of Some Reversible Acetylcholinesterase Inhibitors
Reversible acetylcholinesterase inhibitors are an important group of drug compounds that are used medicinally to treat Alzheimer's disease. In this study, dissociation constant values (pKa) of some reversible acetylcholinesterase inhibitors (donepezil, rivastigmine and galantamine) having different functional groups were determined in different percentages o

15. Aminonaphthoquinone Mannich Bases Derived from Lawsone and Their Copper(II) Complex Derivatives: Synthesis and Potential Cholinesterase Inhibitors as Identified by On-flow Assay
A new series of Mannich bases derived from 2-hydroxy-1,4-naphthoquinone (lawsone), substituted benzaldehydes and two primary amines, and their Cu2+ complexes were synthesized and evaluated for their potential as selective cholinesterase inhibitors (ChEIs). Immobilized capillary enzyme reactors (ICERs) bearing butyrylcholinesterase (BChE) and acetylcholineste

16. In vitro biological screening of the anticholinesterase and antiproliferative activities of medicinal plants belonging to Annonaceae
The aim of this research was to investigate the antiproliferative and anticholinesterase activities of 11 extracts from 5 Annonaceae species in vitro. Antiproliferative activity was assessed using 10 human cancer cell lines. Thin-layer chromatography and a microplate assay were used to screen the extracts for acetylcholinesterase (AchE) inhibitors using Ellm

17. Natural sesquiterpen lactones as acetylcholinesterase inhibitors
Embasamento teórico e proposta de estudo: A quantidade de pessoas idosas que sofrem da doença de Alzheimer está aumentando a cada ano. Inibidores de colinesterase têm mostrado serem eficazes em amenizar os sintomas da doença, abrindo, então, um campo de pesquisa para estes tratamentos. Produtos de origem vegetal, que possuem uma reputação como agente

18. Molecular docking and molecular dynamic studies of semi-synthetic piperidine alkaloids as acetylcholinesterase inhibitors
A mistura dos derivados semissintéticos cloridrato da (-)-3-O-acetil-cassina e cloridrato da (-)-3-O-acetil-espectalina, preparada a partir da mistura dos alcalóides (-)-cassina e (-)-espectalina (4:1) obtida de Senna spectabilis, é um potente inibidor da acetilcolinesterase (AChE), assim justificando mais estudos moleculares. Neste sentido, estudos de do

19. Estudo do mecanismo de ação da atividade acaricida de Calea serrata (Asteraceae) em Rhipicephalus (Boophilus) microplus e da sua toxicidade em roedores
It has been demonstrated that the n-hexane extract of Calea serrata had acaricidal activity against larvae of R. microplus and R. sanguineus. Acetylcholinesterase (AChE), an enzyme that hydrolyses acetylcholine at cholinergic synapses, is a target for pesticides and its inhibition by organophosphates leads to paralysis and death of arthropods. Extensive uses

20. Investigação do efeito neuroprotetor da atorvastatina em um modelo in vitro de toxicidade induzida pelo peptídeo ¿-amiloide
Alzheimer¿s disease is an age-related neurodegenerative disorder characterized by progressive memory loss, inability to perform the activities of daily living and personality changes. AD is characterized histopathologically by the presence of senile plaques, neurofibrillary tangles, synapse loss and neuronal death. Moreover, it is now recognized that neuroi

21. Chemical composition and biological screening of Capsella bursa-pastoris
Capsella bursa-pastoris (L.) Medik. (Brassicaceae) is a wild herb with high nutritional value that can be eaten raw or cooked. A metabolomic study was performed with different extracts of its aerial parts that were tested concerning their antiradical, acetylcholinesterase inhibitory and antibacterial activities. Phenolic compounds were identified and quantif

22. Estudos de modelagem molecular e relação estrutura-atividade da acetilcolinesterase e inibidores em Mal de Alzheimer / Molecular modeling studies and structure-activity relationships of acetylcholinesterase inhibitors in Alzheimers disease.
Alzheimers disease is the leading cause of dementia in the elderly. The progression of symptoms is associated with structural changes in cholinergic synapses in specific brain regions and consequentely to decrease the potential of cholinergic neurotransmission. Thus, the increased capacity of cholinergic neurotransmission is the fundamental mechanism of the

23. Acute electrophysiologic consequences of pyridostigmine inhibition of cholinesterase in humans
The cardiovascular electrophysiologic basis for the action of pyridostigmine, an acetylcholinesterase inhibitor, has not been investigated. The objective of the present study was to determine the cardiac electrophysiologic effects of a single dose of pyridostigmine bromide in an open-label, quasi-experimental protocol. Fifteen patients who had been indicated

24. Efeitos pré e pós sinápticos dos inibidores da acetilcolinesterase na neurotransmissão em musculatura lisa.
Justification: The present work considers the effects of new inhibitors of acetylcholinesterase (AChE) on the reactivity and neurotransmission in rats and mice. The new anticholinesterase compounds, ITH12118 and ITH12117, have an hybrid stucture, derived from the molecule of of the anticholinesterase Tacrine and the 1,4 dihydropyridine nimodipine, a blocker
