Compounds of the following formula are provided:
In the Formula (I), R1 is —X—R1′; in which R1′ is optionally substituted lower alkyl, optionally substituted aryl, optionally substituted heteroaryl, or optionally substituted heterocyclyl, and X is —NH—. R2 is lower alkyl optionally substituted with one, two or three groups chosen from hydroxy, lower alkoxy, and halogen. And R3 is —NR4R5; in which R4 is hydrogen and R5 is lower alkyl substituted with amino; or (ii) R4 and R5 are both lower alkyl optionally substituted with one, two or three groups chosen from hydroxy and amino. It is to be understood that R1′ is not cyclohexylmethyl, phenyl, substituted phenyl, benzyl, phenylethyl, or m-hydroxybenzyl. The compounds inhibit CDK-2 activity and are useful for treating disorders characterized by undesirable cell proliferation.
提供以下公式的化合物:在公式(I)中,R1为—X—R1′;其中,R1′为可选的取代较低烷基,可选的取代芳基,可选的取代杂芳基或可选的取代杂环烷基,X为—NH—。R2为较低烷基,可选地取代有一个、两个或三个羟基、较低烷氧基和卤素中的一个或多个基团。R3为—NR4R5;其中,R4为氢,R5为取代有氨基的较低烷基;或(ii)R4和R5均为较低烷基,可选地取代有一个、两个或三个羟基和氨基中的一个或多个基团。应理解R1′不是环己基甲基、苯基、取代苯基、苄基、苯乙基或间羟基苄基。这些化合物抑制CDK-2活性,并可用于治疗具有不良细胞增殖特征的疾病。
