Discovery of an Orally Bioavailable Dual PI3K/mTOR Inhibitor Based on Sulfonyl-Substituted Morpholinopyrimidines
摘要:
The discovery and optimization of a series of 2-morpholino-pyrimidine derivatives containing various sulfonyl side chains at the C-4 position led to the identification of compound 26 as a potent dual PI3K/mTOR inhibitor. It exhibited high inhibitory activity against PI3K alpha/beta/gamma/delta (IC50 = 20/376/204/46 nM) and mTOR (IC50 = 189 nM), potent functional suppression of AKT phosphorylation (IC50= 196 nM), and excellent antiproliferative effects on a panel of cancer cells. Enzymic data and modeling simulation indicate that a cyclopropyl ring on the C-4 sulfone chain and a fluorine on the C6 aminopyridyl moiety are responsible for its maintained PI3K activity and enhanced mTOR potency, respectively. Furthermore, compound 26 exhibited higher efficiency in the HT-29 colorectal carcinoma xenograft model at the daily dose of 3.75 and 7.5 mg/kg relative to BKM120 at the dose of 15 and 30 mg/kg.

Dimorpholinopyrimidines are useful for inhibiting growth or proliferation of hamartoma tumor cells. Because the Dimorpholinopyrimidines inhibit the growth and proliferation of hamartoma tumor cells they are also useful in treating PTEN hamartoma tumor syndromes. The therapeutic and prophylactic treatments provided by this invention are practiced by administering to a patient in need thereof an amount of a compound of dimorpholinopyrimidine derivative that is effective to inhibit growth or proliferation of the hamartoma tumor cells.
