Reference of 39093-93-1, Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst. In some cases, the catalyzed mechanism may include additional steps.In a article, 39093-93-1, molcular formula is C4H9NO2S, introducing its new discovery.
TETRAHYDROQUINOXALINE UREA DERIVATIVES, PREPARATION THEREOF, AND THERAPEUTIC USE THEREOF
The invention relates to compounds of formula (I), where: A is a bond, an oxygen, or an ?CH2? group; Ar1 is a phenyl or heteroaryl group; Ar2 is a phenyl, heteroaryl, or heterocycloalkyl group; R1a,b,c and R2a,b,c are hydrogen or halogen, or an alkyl, cycloalkyl, or lkyl-cycloalkyl group optionally, substituted by one or more halogen atoms, or a ?OR5 (hydroxy or alkoxy), hydroxy-alkyl, alkoxy-alkyl, alkoxy-alkoxy, halogenoalkyl, ?O-halogenoalkyl, oxo, ?CO-alkyl, ?CO-alkyl-NR6R7, ?CO-halogenoalkyl, ?COOR5, alkyl-COOR5, ?O-alkyl-COOR5, ?SO2-alkyl, ?SO2-cycloalkyl, ?SO2-alkyl-cycloalkyl, ?SO2-alkyl-OR5, ?SO2-alkyl-COOR5, ?SO2-alkyl-NR6R7, ?SO2-halogenoalkyl, alkyl-SO2-alkyl, ?SO2?NR6R7, ?SO2-alkyl-O-alkyl-OR5, ?CONR6R7, -alkyl-CONR6R7, or -alkyl-NR6R7 group, or further R1a, R1b, and R1c are bonded to R2a, R2b, R2c, respectively, and to the carbon atom having same, and are -alkyl-O?; R3 is a hydrogen atom or an alkyl group; R4 is a hydrogen or halogen atom or a cyano, ?OR5, hydroxyalkyl, ?COOR5, ?NR6R7, ONR6R7, ?SO2-alkyl, SO2?NR6R7, ?NR6?COOR5, ?NR6?COR5, or ?CO?NR6-alkyl-OR5 group; R5, R6, and R7 are a hydrogen, or an alkyl or alkyl-phenyl group; and R8 is an alkyl, alkyl-Si(alkyl)3, ?SO2-alkyl-Si(alkyl)3, phenyl, alkoxy-imino group, or alkyl-cycloalkyl group optionally substituted by one or more halogen atoms or one or more hydroxyl or hydroxyl-alkyl groups; or R8 and R9, together with the carbon atoms to which they are bonded, form a cycloalkyl group optionally substituted by one or more halogen atoms or one or more carboxy groups; and R9 is a hydrogen atom or an alkyl group; with the proviso that, when R8 is an alkyl group, it is bonded onto the Ar2 silicon atom. The invention also relates to a method for preparing same and to the therapeutic use thereof.
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 39093-93-1 is helpful to your research. Reference of 39093-93-1
