Bond-length distributions for ions bonded to oxygen: metalloids and post-transition metals

Bond-length distributions for ions bonded to oxygen: alkali and alkaline-earth metals

Bond-length distributions have been examined for 55 configurations of alkali-metal ions and 29 configurations of alkaline-earth-metal ions bonded to oxygen, for 4859 coordination polyhedra and 38 594 bond distances (alkali metals), and for 3038 coordination polyhedra and 24 487 bond distances (alkaline-earth metals). Bond lengths generally show a positively skewed Gaussian distribution that ori...

Bond-length distributions for ions bonded to oxygen: results for the non-metals and discussion of lone-pair stereoactivity and the polymerization of PO4

Bond-length distributions are examined for three configurations of the H ion, 16 configurations of the group 14–16 non-metal ions and seven configurations of the group 17 ions bonded to oxygen, for 223 coordination polyhedra and 452 bond distances for the H ion, 5957 coordination polyhedra and 22 784 bond distances for the group 14–16 non-metal ions, and 248 coordination polyhedra and 1394 bond...

Development of a Method for measuring Reactive Oxygen Radicals Levels In Vitro and Study the Effects of Vitamin C and E on Radical Production Reaction

Background: Free radicals and reactive oxygen species(ROS) are the most important factors in formation of oxidative stress reaction. Now, radical damage has been suggested to contribute to a wide variety of diseases such as Alzheimer, atherosclerosis and cancer. Transition metal ions in the presence of the various biomolecules produce these active compounds. The aim of this study is introducing...

Theoretical Study of Flavopiridol Binded to Transition Metals

More recently medical chemistry research has been focused on proteins that drive and controlcell cycle progression. Among them, the cyclin dependent kinases (cdk’s) are a group ofserine/threonine kinases, which rule the transition between successive stages of the cell cycle. Theactivity of cdk’s is regulated by multiple mechanisms, including binding to cyclins, which is a broadclass of positive...
