The present invention provides novel compounds of the formula (I)
wherein
R is selected from the group consisting of R2, R2NH—, or R3R4N—R5- wherein
R2 is selected from the group consisting of C9-C12 alkyl,
Z is selected from the group consisting of phenyl, heterocycle, cycloalkyl, and naphthanlene; and M is selected from the group consisting of hydrogen, C1-C4 alkyl, and
wherein each C9-C12 alkyl or Z is optionally substituted with 1 to 3 substituents, which may be the same or different, and which are selected from the group consisting of D, E,
wherein each D is independently selected from the group consisting of trifluoromethyl, trifluoromethoxy, and C1-C4 alkoxy; each E is independently selected from the group consisting of Hal, OH, and C1-C8 alkyl;
R3 and R4 are selected from the group consisting of hydrogen, C1-C4 alkyl and (CH2)y-phenyl, wherein y is an integer 0-8, with the proviso that R3 and R4 not both be hydrogen;
R5 is C1-C8 alkylene; and
R1 is selected from the group consisting of cyclopentyl, cyclopentenyl and isopropyl,
and the pharmaceutically acceptable salts, optical isomers, and hydrates thereof,
with the proviso that when R2 is the group
wherein n is 1 or greater; R1 is isopropyl or cyclopentyl; R6 is hydrogen, C1-C4 alkyl, or (CH2)m-phenyl; and Z is phenyl, heterocycle, or cycloalkyl, that Z is substituted with 1 to 3 substituents, which may be the same or different, and which are selected from the group consisting of
In addition, 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.
