Abstract
In line with our previous studies, novel morpholine and benzoxa(or thia)zine lead compounds have been developed through a rational design that modulate a multiplicity of targets against atherosclerosis. We have evaluated the most promising compounds for their efficiency to a) intercept and scavenge free radicals, b) inhibit the metal ion (Cu2+)- induced LDL oxidation c) act intracellularly as antioxidants in THP-1 monocytes from a leukemic patient and d) inhibit the pro-inflammatory enzymes cyclooxygenase-1 (COX-1) and -2 (COX-2) in vitro. Furthermore, two representative compounds were tested for their potential to decrease lipidemic parameters (TC, LDL and TG) in hyperlipidemic mice. Most derivatives indicated a remarkable antioxidant activity, while at the same time exhibited a significant in vitro anti-inflammatory activity, inhibiting COX-1 or/and COX-2 activity at 20 μΜ. In addition, after their long-term administration, compounds 6 and 8 afforded considerable activity in a chronic experimental animal model of hyperlipidemia (after high fat diet administration). The multifunctional pharmacological profile exhibited by the compounds of this study renders them interesting lead compounds for the development of novel agents against atherosclerosis.
Keywords: Design, synthesis, oxidative stress, lipid peroxidation, microsomes, LDL oxidation, squalene synthase inhibitors, cyclooxygenase-1 and -2 inhibitors, triglycerides, total cholesterol, LDL-cholesterol, HDL-cholesterol, atherosclerosis, high fat diet, multifunctional agents.

Chalcogen-modified nucleic acid analogues
Chalcogen-modified nucleosides, nucleotides and oligonucleotides have been of great interest to scientific research for many years. The replacement of oxygen in the nucleobase, sugar or phosphate backbone by chalcogen atoms (sulfur, selenium, tellurium) gives these biomolecules unique properties resulting from their altered physical and chemical properties. The continuing interest in ...read more
