Dysfunctional signaling of the PI3K/AKT/mTOR pathway in cancer and its crucial role in cell growth and survival have made it a much desired target for cancer therapeutics. A series of dimorpholine substituted thienopyrimidine derivatives had been prepared and evaluated in vitro and in vivo. Among them, compound 14o was identified as a dual Class I PI3K and mTOR kinase inhibitor, which had an approximately 8-fold improvement in mTOR inhibition relative to the class I PI3K inhibitor 1 (pictilisib, GDC-0941). Western blot analysis confirmed the 14o mechanistic modulation of the cellular PI3K/AKT/mTOR pathway through inhibiting phosphorylation of both AKT and S6 in human cancer cell lines. In addition, 14o demonstrated significant efficacy in SKOV-3 and U87MG tumor xenograft models without causing significant weight loss and toxicity.
