QSAR analyses have been performed on the substituted indanone and benzylpiperidine ring substructures of a set of acetylcholinesterase, AChE, inhibitors of which 1-benzyl-4-[(5,6-dimethoxy-1-oxoindan-2-yl)methyl]piperidine hydrochloride is a potent in vitro and ex vivo inhibitor. The method of molecular decomposition-recomposition was used to define the(More)
Conformational analyses and molecular-shape comparisons were carried out on an analogue series of indanone-benzylpiperidine inhibitors of acetylcholinesterase (AChE). It was possible to define an active conformation with respect to the flexible geometry of the benzylpiperidine moiety, as well as an active conformation of the indanone ring-piperidine ring(More)
Molecular dynamics (MD) simulations to model possible reaction pathways of the dynemicin-A-DNA cleavage mechanism were performed. Two base-pairs sequences, ApCpTpApCpTp-3'/TpGpApTpGpAp-5' and CpApCpGpGpGp-3'/GpTpGpCpCpCp-5', were considered in the calculations. A model based on a prior study of intercalation of dynemicin-A and posterior activation of the(More)
Intermolecular molecular modeling calculations to determine the intercalation behavior of dynemicin-A with DNA were performed using both static scanning and energy minimization and molecular dynamics relaxation techniques. Two base pair sequences, CpApCpGpGpGp-3'/GpTpGpCpCp-5' and ApCpTpApCpTp-3'/TpGpApTpGpAp-5', were considered in the calculations. The(More)
Serra Gaucha is described as the most important wine region of Brazil. Regarding cultivars widespread in the Serra Gaucha, about 90 % of the area is occupied by vines of Vitis labrusca that is the most important specie used in grape juice production. The objective of this study was to investigate the antioxidant and neuroprotective effect of chronic intake(More)
