title: Pyrazolo[4,3-d]pyrimidines as new generation of cyclin-dependent kinase inhibitors.
abstract: A search among analogues of anti-CDK purines led to the identification of substituted pyrazolo[4,3-d]pyrimidines as novel inhibitors of CDK1/cyclin B. Some of these derivatives also show antiproliferative activity on cancer cell line K-562, thus may find an application as anticancer agents.
