2,6,8,9-Tetrasubstituted Purines as New CDK1 Inhibitors
摘要:
Purine inhibitors of cyclin-dependent kinases attract attention as potential anticancer drugs because their first representative roscovitine recently entered clinical trials. Although well described in terms of structure-activity relationships, we still present here a novel modification of the purine scaffold influencing their inhibitory properties. The introduced C-8 substituents, however, lowered the CDK inhibitory activity of roscovitine, whereas the antiproliferative potential of several derivatives remained high. (C) 2003 Elsevier Ltd.

Heteroaryl sulfonyl compounds and compositions that have a CDK2 Recognition Moiety bound to an electrophile for the selective covalent modification of CDK2 to treat CDK2-mediated disorders are described.
The present invention provides a method for increasing the expression of MAFA in cells expressing markers characteristic of the pancreatic endocrine lineage comprising the steps of culturing the cells expressing markers characteristic of the pancreatic endocrine lineage in medium comprising a sufficient amount of a cyclin-dependent kinase inhibitor to cause an increase in expression of MAFA.
