This application discloses 2-amino-6-anilino-purine derivatives of the formula I
in which
q is 1-5, and
R1 is
&agr;) —S(═O)k—NR6R7, in which
k is 1 or 2,
wherein under the proviso that R6 and R7 cannot be simultaneously hydrogen
&agr;1) R6, R7 can be identical or different from one another and represent an aliphatic, carbocyclic, heterocyclic, carbocyclic-aliphatic or heterocyclic-aliphatic radical; hydrogen or lower aliphatic acyl; or
&agr;2) R6 and R7 together are an alkylene or alkenylene radical having from 3 up to and including 9 C atoms, in which 1-3 C atoms can be replaced by oxygen, sulfur or nitrogen,
&bgr;) N-(aryl lower alkyl)carbamoyl, or
&ggr;) a radical of the formula —NH—S(═O)i—R8, in which
i is 1 or 2,
R8 is an aliphatic, carbocyclic or heterocyclic radical; or
&dgr;) a radical of the formula —NH—C(═O)—R9,
and the other variable substituents are as defined herein. The inventive compounds inhibit p34cdc2/cyclin Bcdc13 kinase and protein tyrosine kinase pp60c-src and can be used for treatment of hyperproliferative diseases, for example tumour diseases, and diseases which respond to inhibition of the activity of protein tyrosine kinase pp60c-src, in particular osteoporosis.
