Synthesis and DPPH scavenging assay of reserpine analogues, computational studies and in silico docking studies in AChE and BChE responsible for Alzheimer's disease

Braz. j. pharm. sci; 51 (1), 2015
Alzheimer's disease (AD) is a fast growing neurodegenerative disorder of the central nervous system and anti-oxidants can be used to help suppress the oxidative stress caused by the free radicals that are responsible for AD. A series of selected synthetic indole derivatives were biologically evaluated to...

Antioxidant and anticholinesterase investigations of Rumex hastatus D. Don: potential effectiveness in oxidative stress and neurological disorders

Biol. Res; 48 (), 2015
BACKGROUND: Rumex species are traditionally used for the treatment of neurological disorders including headache, migraine, depression, paralysis etc. Several species have been scientifically validated for antioxidant and anticholinestrase potentials. This study aims to investigate Rumex hastatus D. Don c...

Anticholinesterse and antioxidant investigations of crude extracts, subsequent fractions, saponins and flavonoids of atriplex laciniata L: potential effectiveness in Alzheimer's and other neurological disorders

Biol. Res; 48 (), 2015
BACKGROUND: Atriplex laciniata L. was investigated for phenolic, flavonoid contents, antioxidant, anticholinesterase activities, in an attempt to explore its effectiveness in Alzheimer's and other neurological disorders. Plant crude methanolic extract (Al.MeF), subsequent fractions; n-hexane (Al.HxF), ch...

Investigations of anticholinestrase and antioxidant potentials of methanolic extract, subsequent fractions, crude saponins and flavonoids isolated from Isodon rugosus

Biol. Res; 47 (), 2014
BACKGROUND: Based on the ethnomedicinal uses and the effective outcomes of natural products in various diseases, this study was designed to evaluate Isodon rugosus as possible remedy in oxidative stress, alzheimer's and other neurodegenerative diseases. Acetylecholinestrase (AChE) and butyrylcholinestera...

2-Phenitidine derivatives as suitable inhibitors of butyrylcholinesterase

Braz. j. pharm. sci; 49 (1), 2013
This manuscript reports the synthesis of a series of N-substituted derivatives of 2-phenitidine. First, the reaction of 2-phenitidine (1) with benzene sulfonyl chloride (2) yielded N-(2-ethoxyphenyl) benzenesulfonamide (3), which further on treatment with sodium hydride and alkyl halides (4a-g) furnished...

Colinesterasas eritrocitaria y plasmática en trabajadores con enfermedades crónicas controladas y en usuarios de medicamentos

Iatreia; 19 (1), 2006
Problema: los valores fisiológicos de colinesterasas se conocen para personas y trabajadores sanos, pero poco se sabe de ellos cuando se trata de sujetos con enfermedades crónicas controladas, usualmente con medicamentos. ¿Cuál es el efecto de la enfermedad, de las drogas o de ambas en los niveles de...

Utilização de 2-metil-1-propenilbenzoato na determinação quimiluminescente de esterases de monócitos, butirilcolinesterase sérica e de conjugados de peroxidase

Recentemente, desenvolvemos um novo ensaio quimiluminescente disparado por hidrolases sobre 2-metil-1-propenilbenzoato (MPB) na presença de `H IND. 2ï`O IND. 2ï e peroxidase de raiz forte (HRP) (YAVO, et al. (1996) Anal. Biochem., v. 234, p. 215-220). A hidrólise de MPB, catalisada por esterase, orig...
