Development of Pyridopyrimidines as Potent Akt1/2 Inhibitors
摘要:
This communication reports a new synthetic route of pyridopyrimidines to facilitate their structural optimization in a library fashion and describes the development of pyridopyrimidines that have excellent enzymatic and cell potency against Akt1 and Akt2. This series also shows a high level of selectivity over other closely related kinases and significantly improved caspase-3 activity with the more optimized compounds.

The present invention is directed to compounds which contain substituted 5-deazapteridine moieties which inhibit the activity of Akt, a serine/threonine protein kinase. The invention is further directed to chemotherapeutic compositions containing the compounds of this invention and methods for treating cancer comprising administration of the compounds of the invention.

The use of dianhydrogalactitol provides a novel therapeutic modality for the treatment of malignancies of the central nervous system in pediatric patients, including glioblastoma multiforme (GBM) high grade glioma, and medulloblastoma. Dianhydrogalactitol acts as an alkylating agent on DNA that creates N

methylation and that can induce double-stranded breaks in DNA. Dianhydrogalactitol is effective in suppressing the growth of cancer stem cells and is active against tumors that are refractory to temozolomide, cisplatin, and tyrosine kinase inhibitors; the drug acts independently of the MGMT repair mechanism. Dianhydrogalactitol can be used together with other anti-neoplastic agents (e.g. cisplatin) and can possess additive or super-additive effects.
