Bone-Targeted 2,6,9-Trisubstituted purines: novel inhibitors of Src tyrosine kinase for the treatment of bone diseases
摘要:
Novel bone-targeted 2,6,9-trisubstituted purine template-based inhibitors of Src tyrosine kinase are described. Drug design studies of known purine compounds revealed that both positions-2 and -6 were suitable for incorporating bone-seeking moieties. A variety of bone-targeting groups with different affinity to hydroxyapatite were utilized in the study. Compound 3d was determined to be a potent Src inhibitor and was quite selective against a panel of other protein kinases. (C) 2003 Elsevier Ltd. All rights reserved.
