Mössbauer Studies on the Iron-ligand Binding in Hemoproteins and Their Related Compounds
نویسنده
چکیده
The electronic structure of the heme iron in hemoproteins is characterized by its changeable valence and spin states. These features are discussed in hemoproteins and their related model compounds. The iron-ligand binding, especially the reversible dioxygen binding in myoglobin and hemoglobin is discussed in details by using the f4;issbauer spectroscopic knowledge obtained from the experiments with Mb single crystals and model compounds. A comparison of recent experimental evidences with calculations has improved the knowledge of the iron-dioxygen binding structure. The electronic structures in the deoxygenated state and the CO compound are also deduced. In addition, kinetics of ligand-binding to hemoproteins is reported.

Interference with microtubule polymerization results in cell cycle arrest leading to cell death. Colchicine is a well-known microtubule polymerization inhibitor which does so by binding to a specific site on tubulin. A set of 3',4'-bis (substituted phenyl)-4'H-spiro[indene-2,5'-isoxazol]-1(3H)-one derivatives with known antiproliferative activities were evaluated for their tubulin binding modes...
