drug targets in cancer therapy. Findings from a previous study suggested 7-azaindole as a privileged scaffold for producing inhibitors of CDK9/CyclinT and Haspin. Inspired by these findings, the current study synthesised and evaluated thirteen (13) C6-substituted 7-azaindole and twenty (20) C4-substituted structurally related 7H-pyrrolo[2,3-d]pyrimidine derivatives against a panel of protein kinases

The present invention relates to the synthesis of 6-substituted 7-deazapurines and their corresponding nucleosides by coupling aryl or alkyl Grignard reagents with halogenated purine nucleosides in the presence of iron or an iron/copper mixture such as Fe(acac)3/Cul. The present invention also relates to pharmaceutical compositions comprising said compounds and the use of said pharmaceutical compositions to treat or prevent viral infections.
to 6-substituted 7-deazapurine and the corresponding nucleosides by coupling aryl or alkyl Grignardreagents and halogenated purine nucleosides in the presence of Fe(acac)3/CuI is described. A series of 6-substituted 7-deazapurines and the corresponding nucleosides were obtained in medium to good yields. For the synthesis of modified nucleosides that will be the subject of biological testing, we propose
The present invention provides compounds for modulating protein kinase enzymatic activity for modulating cellu-lar activities such as proliferation, differentiation, programmed cell death, migration and chemoinvasion. Even more specifically, the invention provides compounds for modulating c-Kit kinase activity and methods of treating diseases mediated by c-Kit activity utilizing the compounds and pharmaceutical compositions thereof.
This application discloses compounds according to generic Formula I wherein all variables are defined as described herein, which inhibit Btk. The compounds disclosed herein are useful to modulate the activity of Btk and treat diseases associated with excessive Btk activity. The compounds are further useful to treat inflammatory and auto immune diseases associated with aberrant B-cell proliferation such as rheumatoid arthritis. Also disclosed are compositions containing compounds of Formula I and at least one carrier, diluent or excipient.
