5-Lipoxygenase (5LO), by producing leukotrienes, is a proinflammatory enzyme, and there is evidence suggesting that it is up-regulated with aging and may be involved in Alzheimer's disease (AD). In this paper, we studied the effect of 5LO-targeted gene disruption on the amyloid phenotype of a transgenic mouse model of AD, the Tg2576. Amyloid-beta (Abeta)(More)
The neuropathology of Alzheimer's disease (AD) is characterized by deposits of amyloid beta (Abeta) peptides and neurofibrillary tangles, but also, among other aspects, by signs of a chronic inflammatory process. Epidemiological studies have shown that long-term use of nonsteroidal antiinflammatory drugs (NSAIDs) reduces the risk of developing AD and delays(More)
Polyphenols are an important class of phytochemicals, and several lines of evidence have demonstrated their beneficial effects in the context of a number of pathologies including neurodegenerative disorders such as Alzheimer's and Parkinson's disease. In this report, we review the studies on the effects of polyphenols on neuronal survival, growth,(More)
DNA intercalators belong to aromatic heterocyclic compounds interacting reversibly with DNA. These compounds have been used extremely as cytotoxic agents against cancer. In this study, the synthesis and biological activity of some novel derivatives of cyclopenta [b] quinoline-1, 8-dione as new intercalating agent were investigated. Twenty novel derivatives(More)
A set of novel Schiff bases of isatin were synthesized and characterized by reaction of isatin with various aromatic or heterocyclic primary amines. Cytotoxic activities for some of the synthesized compounds were evaluated by MTT assay in three human cancer cell lines (HeLa, LS180 and Raji). Half of the tested compounds showed good cytotoxicity in HeLa(More)
The plants of the genus Salvia synthesize several types of secondary metabolites with antimicrobial, cytotoxic, and radical scavenging activities and are used in the folk medicine of different countries. Eleven Salvia species including S. aegyptiaca, S. aethiopis, S. atropatana, S. eremophila, S. hypoleuca, S. limbata, S. nemorosa, S. santolinifolia, S.(More)
OBJECTIVES Dilated cardiomyopathy is the most prevalent type of cardiomyopathy in children, which results in congestive heart failure and causes significant morbidity and mortality. This study, aims to investigate the effect of supplementation with omega-3 polyunsaturated fatty acids (n-3 PUFA) on heart function and oxidative stress biomarkers in these(More)
The plants of the genus Salvia L. are important medicinal herbs of the Lamiaceae family and some of them such as S. officinalis (sage), S. miltiorrhiza (red sage, Danshen) and S. sclarea (clary sage) have been used as medicinal plants in the folk medicine of several countries. In this review, we discuss the reports that have examined Salvia species with the(More)
Thienopyridine derivatives possess various promising biological properties and particularly cytotoxic effect. In vitro cytotoxic activities of some thienopyridine analogous were evaluated by MTT reduction assay in three human cancer cell lines (HL-60, MCF-7, and LS-180). The compounds showed a wide range of cytotoxic activities and their IC50 values ranged(More)
