Gedatolisib, also known as PKI-587 and PF-05212384, is an agent targeting the phosphatidylinositol 3 kinase (PI3K) and mammalian target of rapamycin (mTOR) in the PI3K/mTOR signaling pathway, with potential antineoplastic activity. Upon intravenous administration, PI3K/mTOR kinase inhibitor PKI-587 inhibits both PI3K and mTOR kinases, which may result in apoptosis and growth inhibition of cancer cells overexpressing PI3K/mTOR. Activation of the PI3K/mTOR pathway promotes cell growth, survival, and resistance to chemotherapy and radiotherapy; mTOR, a serine/threonine kinase downstream of PI3K, may also be activated independent of PI3K.
PKI-587 is a PI3K/mTOR inhibitor, currently being developed by Pfizer. The PI3K/Akt signaling pathway is a key pathway in cell proliferation, growth, survival, protein synthesis, and glucose metabolism. It has been recognized recently that inhibiting this pathway might provide a viable therapy for cancer. PKI-587 has shown excellent activity in vitro and in vivo, with antitumor efficacy in both subcutaneous and orthotopic xenograft tumor models when administered intravenously.

Bis(morpholino-1,3,5-triazine) Derivatives: Potent Adenosine 5′-Triphosphate Competitive Phosphatidylinositol-3-kinase/Mammalian Target of Rapamycin Inhibitors: Discovery of Compound 26 (PKI-587), a Highly Efficacious Dual Inhibitor
Abstract
The PI3K/Akt signaling pathway is a key pathway in cell proliferation, growth, survival, protein synthesis, and glucose metabolism. It has been recognized recently that inhibiting this pathway might provide a viable therapy for cancer. A series of bis(morpholino-1,3,5-triazine) derivatives were prepared and optimized to provide the highly efficacious PI3K/mTOR inhibitor 1-(4-{[4-(dimethylamino)piperidin-1-yl]carbonyl}phenyl)-3-[4-(4,6-dimorpholin-4-yl-1,3,5-triazin-2-yl)phenyl]urea 26 (PKI-587). Compound 26 has shown excellent activity in vitro and in vivo, with antitumor efficacy in both subcutaneous and orthotopic xenograft tumor models when administered intravenously. The structure−activity relationships and the in vitro and in vivo activity of analogues in this series are described.

PAPER
New and Practical Synthesis of Gedatolisib
http://pubs.acs.org/doi/10.1021/acs.oprd.7b00298
Abstract
A new, practical, and convergent synthetic route of gedatolisib, an antitumor agent, is developed on a hectogram scale which avoids the Pd coupling method. The key step is adopting 6-(4-nitrophenyl)-1,3,5-triazine-2,4-diamine and 2,2′-dichlorodiethyl ether to prepare the key 4,4′-(6-(4-nitrophenyl)-1,3,5-triazine-2,4-diyl)dimorpholine in 77% yield and 98.8% purity. Gedatolisib is obtained in 48.6% yield over five simple steps and 99.3% purity (HPLC). Purification methods of the intermediates and the final product involved in the route are given.
