Reduction ofo-iodosobenzoate ion by sulfides and its oxidative regeneration
摘要:
o-Iodosobenzoate and o-iodoxybenzoate ion (IBA and IBX, respectively) are turnover catalysts of hydrolyses of phosphonofluoridates and non-toxic simulants. Reactions of IBA with phosphonothioates are stoichiometric because sulfides (e.g. 4-methoxybenzenethiol) reduce IBA to o-iodobenzoate ion. Oxidants, e.g. HSO5-, as OXONE, and magnesium peroxyphthalate, MPPA, regenerate IBA and gradually oxidize it to IBX, which eventually decomposes. The procedure was tested on hydrolyses of p-nitrophenyl diphenylphosphate (pNPDPP) and 4-nitrobenzenesulfonyl fluoride, 1, catalyzed by IBA, and the catalyzed hydrolysis of 1 was examined. Some of the oxidation products of 4-methoxybenzeue thiol were identified by H-1 NMR spectroscopy and oxidative decomposition of IBX was monitored. Periodate ion slowly oxidized o-iodobenzoate ion to IBA and IBX. Copyright (C) 1999 John Wiley & Sons, Ltd.

In its many embodiments, the present invention provides a novel class of pyrimidine analogs of formula (V) as targeted mechanism-based modulators of cell cycle checkpoints. Cancers and/or malignancies can be treated by administration of a cell cycle checkpoint modulator of the invention. Also discussed are suitable combinations of the cell cycle checkpoint modulator with a checkpoint kinase inhibitor to produce synergistic apoptosis in cancer cells. The invention includes methods of treating cancers by administering the combination of the cell cycle checkpoint modulator and the checkpoint kinase inhibitor, pharmaceutical compositions comprising the activator as well as the combination and pharmaceutical kits.
