This book is concerened with studying the oxidation of 3-acetyl-4-hydroxyquinolin-2(1H)-one via selenium dioxide. The first chapter was introduced the synthesis and chemical reactivity of acetylquinolinone. Then, the second chapter is divided to Study the oxidation reaction and show the chemical reactivity of - keto acid with different reagents. The third chapter is showed the thermal Study for -keto acid and ester followed by in fourth chapter; the biological activity for different compound. Afterwards, in five chapter, there were chemistry and biochemistry experimental. Finally conclusion...

Aluminum (Al) is a common environmental metal with high human exposure potential through water, food, air, medications, and dust, linked to neurotoxic effects like speech and motor issues, tremors, dyspraxia, and cognitive decline. Research highlights Al's impact on neurobehavioral and neurophysiological health, leading to inflammation, cell apoptosis, and lower brain-derived neurotrophic factor (BDNF) levels. As the brain is especially vulnerable to Al toxicity due to elevated oxidative stress markers such as reactive oxygen species (ROS) and lipid peroxidation (LPO), antioxidant therapies...

Throughout the centuries natural compounds have been widely used for the prevention and treatment of different diseases. One of the groups of natural compounds that has recently attracted increased interest of researchers and clinicians are fungal polysaccharides. Along with the macroscopic fungi, or mushrooms, yeasts also represent a source of valuable polysaccharides contained in their cell walls. Beta glucan as part of yeasts cell wall were highly concentrated on their biological activity and their interaction as non-adaptive immunomodulating agent and other biological effects when applied...
