标 题 :Synthesis of 3,3{40 -diaminobenzidine from 3,3{40 -dichlorobenzidine
发明人：CHENEVEY EDWARD C; DRUIN MELVIN L; ORINGER KENNETH
权利人:CELANESE CORP
摘要:A process for the synthesis of 3,3''-diaminobenzidine from 3,3''dichlorobenzidine with NH3 in the presence of a catalyst consisting essentially of cuprous chloride. This process produces higher yields of a purer product than prior processes employing catalysts which are a mixture of cuprous chloride and calcium chloride.

标 题 :Control of immune responses by modulating activity of glycosyltransferases
发明人：MARTH JAMEY D; PAULSON JAMES C
权利人:ABARON BIOSCIENCES INC; UNIV CALIFORNIA
摘要:The invention provides methods for inhibiting immune responses by inhibiting the biosynthesis of the sialyl galactosides that are involved in immune responses. In particular, B lymphocyte-mediated immune responses are mediated by interfering with synthesis of α2,6 sialylgalactosides, while T lymphocyte-mediated immune responses are inhibited by blocking synthesis of α2,3 sialylgalactosides. The inhibition is accomplished by, for example, inhibiting the activity of a glycosyltransferase involved in synthesis of the respective sialyl galactoside.

标 题:One pot synthesis of 5,10-dihydrophenazine compounds and 5,10-substituted dihydrophenazines
发明人：GIRI PUNAM; BYKER HARLAN J; BAUMANN KELVIN L
权利人:GENTEX CORP
摘要:Dihydrophenazines and bis(dihydrophenazines) are prepared in high yield under commercially viable reaction conditions by reacting a catechol with a 1,2-diaminoaryl compound, wherein either the catechol or the 1,2-diaminoaryl compound is provided in at least 50% molar stoichiometric excess. The product may be oxidized to the corresponding phenazine, but is preferably derivatized at one or both of the 5,10-positions to form a monosubstituted or disubstituted dihydrophenazine or bis(dihydrophenazine). Most preferably, 5,10-dialkyl-5,10-dihydrophenazines are prepared starting from catechol and 1,2-diaminoaryl compound in a one pot synthesis. The products are useful as dyes, and in particular as chromophores in electrochromic systems.

摘要:THIS INVENTION DEALS WITH A NOVEL, RELATIVELY SIMPLE PROCESS OF PREPARING POLYBENZOTHIAZOLINES, ((-NH-CH(-)-S-)>AR<(-NH-CH(-Z(-))-S-))N BY REACTING DIALDEHYDES, Z-(CH=O)2, AND (HS)2-AR(-NH2)2 IN A SOLVENT IN AN INERT ATMOSPHERE AND THEREAFTER OXIDIZING THE POLYBENZOTHIAZOLINES TO POLYBENZOTHIAZOLES, ((-N=C(-)-S-)>AR<(-N=C(-Z(-))-S-))N WHEREIN AR REPRESENTS A TETRAVALENT AROMATIC MOIETY IN WHICH THE NITROGEN AND SULFUR ATOMS IN EACH PAIR ARE DISPOSED ORTHO TO EACH OTHER AND Z REPRESENTS A DIVALENT HYDROCARBON MOIETY AS THE RESIDUE OF THE DIALDEHYDE, Z(CHO)2. NEW TYPES, AS WELL AS THE KNOW TYPES OF POLYBENZOTHIAZOLES HAVE BEEN PREPARED BY THIS PROCESS.
