The present invention provides novel compounds of the formula (I)
wherein
R is selected from the group consisting of R2, R2NH—, or H2N—R3— wherein
R2 is selected from the group consisting of C1-C8 alkyl and
wherein
Z is selected from the group consisting of phenyl, heterocycle and cycloalkyl, each R4 is independently hydrogen or C1-C4 alkyl, and n is an integer 1-8;
wherein each C1-C8 alkyl and Z is optionally substituted with 1 to 3 substituents, which may be the same or different, selected from the group consisting of Ha1, OH, and C1-C4 alkyl;
R3 is C1-C8 alkylene; and
R1 is selected from the group consisting of cyclopentyl and isopropyl, and the pharmaceutically acceptable salts, optical isomers, and hydrates thereof.
In addition, the present invention provides a method of inhibiting cell cycle progression. More specifically, the present invention provides a method of inhibiting cyclin dependent kinases, particularly cdk-2.
The present invention also provides a method of preventing apoptosis in neuronal cells and a method of inhibiting the development of neoplasms.
In addition, the present invention provides a composition comprising an assayable amount of a compound of Formula (I) in admixture or otherwise in association with an inert carrier. The present invention also provides a pharmaceutical composition comprising an effective inhibitory amount of a compound of Formula (I) in admixture or otherwise in association with one or more pharmaceutically acceptable carriers or excipients.
本发明提供了公式(I)中的新化合物,其中R选自由R2、R2NH—或H2N—R3—的组,其中R2选自C1-C8烷基的组,Z选自苯基、杂环和环烷基的组,每个R4独立地为氢或C1-C4烷基,n为1-8的整数;其中每个C1-C8烷基和Z可选地与1到3个取代基取代,这些取代基可以是相同的或不同的,选自Ha1、OH和C1-C4烷基的组;R3为C1-C8烷基;R1选自环戊基和异丙基的组,以及其药学上可接受的盐、光学异构体和水合物。此外,本发明提供了一种抑制细胞周期进展的方法。更具体地说,本发明提供了一种抑制cyclin依赖性激酶,特别是cdk-2的方法。本发明还提供了一种防止神经细胞凋亡和抑制肿瘤发展的方法。此外,本发明提供了一种包含公式(I)化合物的测定量的组合物,与惰性载体混合或以其他方式结合。本发明还提供了一种包含有效抑制量的公式(I)化合物的药物组合物,与一个或多个药学上可接受的载体或赋形剂混合或以其他方式结合。
