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.
