abstract part one: the electrode oxidation potentials of a series of eighteen n-hydroxy compounds in aqueous solution were calculated based on a proper thermodynamic cycle. the dft method at the level of b3lyp-6-31g(d,p) was used to calculate the gas-phase free energy differences ,and the polarizable continuum model (pcm) was applied to describe the solvent and its interaction with n-hydroxy ...
Background and Objective: Compounds of heavy metals such as vanadium, nickel, and cobalt can be useful in treatment of many diseases. There are several reports on the biological effects of vanadium compounds including insulin-like action and reduction of hypertension. A number of studies on vanadium have shown its promising ability to inhibit cancers in a variety of malignant cell lines. The go...
An easily-accessible neutral scandium complex Sc[OC(CH3)2CH2PPh2][O-2,6-tBu2-C6H3]2[THF] behaves as a reactive Sc/P frustrated Lewis pair, which when added to organic and inorganic substrates e.g. carbonyl compounds, transition-metal chlorides, and diazoalkane compounds, yields unique and intriguing addition products such as a Sc/Rh heterobimetallic complex and a Sc phosphazine complex.
Background & Aims: Angiogenesis plays an important role in tumor growth and metastasis of cancer; therefore, compounds that inhibit the angiogenesis process can prevent tumor growth. Recently, Schiff base complexes have become important due to properties such as anticancer, anti-oxidant, and the like. In this study, the angiogenesis effect of the copper Schiff base complex on the chorioallantoi...
In this work, a Genetic Algorithm boosted Least Square Support Vector Machine model by a set of linear equations instead of a quadratic program, which is improved version of Support Vector Machine model, was used for estimation of 98 pure compounds second virial coefficient. Compounds were classified to the different groups. Finest parameters were obtained by Genetic Algorithm method ...
