Design of Novel 3-Pyrimidinylazaindole CDK2/9 Inhibitors with Potent In Vitro and In Vivo Antitumor Efficacy in a Triple-Negative Breast Cancer Model
摘要:
In the present study, a novel series of 3-pyrimidinylazaindoles were designed and synthesized using a bioinformatics strategy as cyclin-dependent kinases CDK2 and CDK9 inhibitors, which play critical roles in the cell cycle control and regulation of cell transcription. The present approach gives new dimensions to the existing SAR and opens a new opportunity for the lead optimizations from comparatively inexpensive starting materials. The study led to the identification of the alternative lead candidate 4ab with a nanomolar potency against CDK2 and CDK9 and potent antiproliferative activities against a panel of tested tumor cell lines along with a better safety ratio of similar to 33 in comparison to reported leads. In addition, the identified lead 4ab demonstrated a good solubility and an acceptable in vivo PK profile. The identified lead 4ab showed an in vivo efficacy in mouse triple-negative breast cancer (TNBC) syngeneic models with a TGI (tumor growth inhibition) of 90% without any mortality growth inhibition in comparison to reported leads.

to its value in the design of inhibitors of diseases related protein kinases. However, this scaffold has not been evaluated against Haploid germ cell-specific nuclear protein kinase (Haspin). Herein, we report the synthesis of a select set of 7-azaindole derivatives and their evaluation against Haspin. The compounds were also evaluated against CDK9/Cyclin T kinase.
