A novel series of hydrazones derived from syringaldehyde and their antioxidant properties have been explored. Several employed methods such as scavenging effect on 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical and 2,2'-azinobis(3-ethylbenzthiazoline-6-sulfonic acid) (ABTS(+)) radical cation expressed as Trolox equivalent antioxidant capacity (TEAC),(More)
Opuntia species have been used for thousands of years as a folk medicine in the treatment of diseases. However, the components and protective mechanisms are still unclear. We make the hypothesis that Opuntia species may protect the development of oxidative stress-associated diseases, such as atherosclerosis or colon cancer, via their antioxidant properties.(More)
AIMS Protein disulfide isomerase (PDI) is an abundant endoplasmic reticulum (ER)-resident chaperone and oxidoreductase that catalyzes formation and rearrangement (isomerization) of disulfide bonds, thereby participating in protein folding. PDI modification by nitrosative stress is known to increase protein misfolding, ER stress, and neuronal apoptosis. As(More)
Actin remodeling is a dynamic process associated with cell shape modification occurring during cell cycle and proliferation. Oxidative stress plays a role in actin reorganization via various systems including p38MAPK. Beside, the mitogenic response evoked by hydrogen peroxide (H2O2) in fibroblasts and smooth muscle cells (SMC) involves the metalloproteinase(More)
A novel series of hydrazones derived from substituted benzaldehydes have been synthesized as potential antiatherogenic agents. Several methods were used for exploring their antioxidant and cytoprotective properties, such as their scavenging effect on 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical, the inhibition of superoxide anion (O₂(·-)) generation and the(More)
Lipid A is a major hydrophobic component of lipopolysaccharides (endotoxin) present in the membrane of most Gram-negative bacteria, and the major responsible for the bioactivity and toxicity of the endotoxin. Previous studies have demonstrated that the late afterglow region of flowing post-discharges at reduced pressure (1-20 Torr) can be used for the(More)
The neovascularization of atherosclerotic lesions is involved in plaque development and may contribute to intraplaque hemorrhage and plaque fragilization and rupture. Among the various proangiogenic agents involved in the neovascularization process, proatherogenic oxidized LDLs (oxLDLs) contribute to the formation of tubes via the generation of sphingosine(More)
A series of bis-hydrazones derived from diaryl and diaryl ether hydroxybenzaldehyde frames 1 and 2 have been synthesized as potential antioxidant and antiangiogenic agents, two properties required to limit atherogenesis and cardiovascular events. These compounds were evaluated for their ability to neutralize free radical formation, to block endothelial(More)
