چکیده
Uma nova série de nove 3-fosfato-(4,4,4-trifluor-butil)-carbamatos de etila (compostos fosfatocarbamato), foram obtidos através da reação de (4,4,4-trifluor-3-hidroxibut-1-il)-etil carbamatos com oxicloreto de fósforo seguido de adição de álcoois. Os produtos foram caracterizados por espectroscopia de RMN de H, C, P e F, CG-EM e análise elementar. Todos os compostos sintetizados foram testados para a inibição da enzima acetilcolinesterase (AChE) usando o método de Ellman. Todos os compostos analisados contendo os grupos carbamato e fosfato em sua estrutura, mostraram inibição enzimática, sendo que o composto contendo o grupo dietóxi (2b) apresentou a maior atividade inibitória. Estudos de modelagem molecular foram realizados para obter informações detalhadas entre o sítio ativo da enzima acetilcolinesterase e os compostos candidatos a inibição, obtendo-se valiosas informações estruturais com relação à inibição de enzima acetilcolinesterase.

A Convinent Route for Synthesis of New Stable 1, 4- Diionic Compounds from Three Component Reactiones of 4,4,4- Trifluoro-1-thiophen-2-yl-butan-1,3-dione, Dialkyl Acetylenicesters and Azines
Multicomponent reactions involving azines (4-methylpyridine, isoquinoline and N-methyl imidazole) and acetylenic ester were undertaken in the presence of CH compound such as 2-furoyl trifluoroacetone(4,4,4-trifluoro-1-thiophen-2-yl-butan-1,3-dione) to generate enaminoesters as stable 1,4-diionic compounds in high yields.
متن کامل2-(2-(4-Benzoylpiperazin-1-yl)ethyl)isoindoline-1,3-dione derivatives: Synthesis, docking and acetylcholinesterase inhibitory evaluation as anti-alzheimer agents
Objective(s): Alzheimer’s disease (AD) as progressive cognitive decline and the most common form of dementia is due to degeneration of the cholinergic neurons in the brain. Therefore, administration of the acetylcholinesterase (AChE) inhibitors such as donepezil is the first choice for treatment of the AD. In the present study, we focused on the synthesis and anti-cholinesterase evaluation of n...
