Tetrasubstituted Imidazole Inhibitors of Cytokine Release: Probing Substituents in the N-1 Position
摘要:
We prepared novel 1,2,4,5-tetrasubstituted imidazole derivatives with high anti-inflammatory activity by using our previously described regiospecific synthesis. Systematic optimization of the imidazole N-1 substituent resulted in compound 9b that potently inhibited the mitogen-activated protein kinase p38 (p38 IC50 = 0.218 muM) as well as the release of the proinflammatory cytokines interleukin-1beta (IL-1beta) and tumor necrosis factor alpha. (TNFalpha) from human whole blood after stimulation with LPS. Furthermore, compound 9b exhibited reduced cytochrome P450 interaction in comparison with SB203580. This result is particularly important, since cytochrome P450 interaction is observed for some p38 inhibitors and in turn can potentially cause drug-drug interaction or lead to other hepatic changes such as P450 enzyme induction.
Synthesis of Hexadentate Hexahydro-1,3,5-triazine-Based Ligands and their Copper(I) Complexes
摘要:
Hexadentate ligands were formed by the reaction of primary dimethylaminoethyl- or methoxyethylamines with formaldehyde. The resulting N,N',N"-functionalized hexahydro-1,3,5-triazines contain pending amino or ether functionalities which are able to coordinate to metals in addition to the ring nitrogen atoms. Both ligands were reacted with CuBr, and novel tricopper clusters were isolated and characterized by X-ray structure analysis. In these compounds a ring nitrogen atom, the pending amino or ether functionality, and two bridging bromine atoms coordinate each of the copper atoms.

Zur Herstellung von lichtstabilen Polyurethan-Integralschaumstoffen, insbesondere Weichintegralschaumstoffen, werden aliphatische und/oder cycloaliphatische Polyisocyanate, vorzugsweise urethan- und/oder biuretgruppenhaltige aliphatische und/oder cycloaliphatische Polyisocyanate mit Polyolen in Gegenwart von Treibmitteln, einer synergistisch wirkenden Katalysatorkombination, bestehend aus Alkalihydroxiden, Alkalialkoholaten, Alkaliphenolaten, Alkalisalzen schwacher Säuren und/oder Hexahydrotriazin-derivaten und einer organischen Zinn-, Zink- und/oder Eisen(II)-verbindung sowie gegebenenfalls Hilfs- und Zusatzstoffen zur Reaktion gebracht.
Vorzugsweise verwendet wird eine Katalysatorkombination aus Tri-(dimehtylaminopropyl)-s-hexahydrotriazin und Dibutylzinndilaurat.
Polyurethan-Integralschaumstoffe in der flexiblen Einstellung eignen sich zur Herstellung von Automobilteilen, wie Nackenstützen, Armlehnen, Crash-pads und Stoßstangen, Schuhsohlen und Sportmatten; die harten Einstellungen finden Verwendung als Sportartikel, Fensterrahmen und Holzersatz.
