Compounds of the following formula are provided:
In the Formula (I), R
1
is —X—R
1
′; in which R
1
′ is optionally substituted lower alkyl, optionally substituted aryl, optionally substituted heteroaryl, or optionally substituted heterocyclyl, and X is —NH—. R
2
is lower alkyl optionally substituted with one, two or three groups chosen from hydroxy, lower alkoxy, and halogen. And R
3
is —NR
4
R
5
; in which R
4
is hydrogen and R
5
is lower alkyl substituted with amino; or (ii) R
4
and R
5
are both lower alkyl optionally substituted with one, two or three groups chosen from hydroxy and amino. It is to be understood that R
1
′ 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′为可选择取代的低烷基、可选择取代的芳基、可选择取代的杂芳基或可选择取代的杂环烷基,X为—NH—。R2为低烷基,可选择取代一个、两个或三个羟基、低烷氧基或卤素基。R3为—NR4R5;其中R4为氢,R5为取代氨基的低烷基;或(ii)R4和R5均为低烷基,可选择取代一个、两个或三个羟基和氨基。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。这些化合物能够抑制CDK-2活性,并用于治疗具有不良细胞增殖特征的疾病。
