Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics, 127-63-9, Name is Sulfonyldibenzene, SMILES is O=S(C1=CC=CC=C1)(C2=CC=CC=C2)=O, belongs to isothiazole compound. In a document, author is FROLUND, B, introduce the new discover, Name: Sulfonyldibenzene.
SYNTHESIS AND RECEPTOR-BINDING OF 5-AMINO[H-3](2)METHYL-3-ISOTHIAZOLOL ([H-3]THIOMUSCIMOL), A SPECIFIC GABA(A) AGONIST PHOTOAFFINITY LABEL
The synthesis of tritium labelled thiomuscimol (5-amino[H-3](2)methyl-3-isothiazolol) (7c), a specific and high-affinity agonist photoaffinity label for GABA(A) receptors, is described. The synthesis of 7c is based on a procedure for the preparation of 5-amino[H-2](2)methyl-3-isothiazolol (7b). Methyl 3-ethoxyisothiazole-5-carboxylate (3), synthesized from 3-hydroxyisothiazole-5-carboxamide (1) via the corresponding methyl ester (2), was reduced with sodium borotritide to give 3-ethoxy-5-hydroxy[H-3](2)-methyl-3-isothiazole (4c). 3-Ethoxy-5-phthalimido[H-3](2)- methylisothiazole (6c), synthesized from the 5-chloro[H-3](2)methyl analogue (5c) of (4c), was deprotected by treatment with concentrated hydrochloric acid to give 7c with a specific radioactivity of 29 Ci/mmol. In pilot binding assays, 7c was shown to bind to membranes from rat forebrain in a saturable manner and with K-D and B-max values of 28 +/- 6 nM and 50 +/- 4 fmol/mg original tissue, respectively.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 127-63-9 is helpful to your research. Name: Sulfonyldibenzene.
