scaffold hopping strategy, including intellectual property availability assessment, was successfully applied for the discovery of novel PI3K inhibitors. Compounds were designed based on the chemical structure of the lead compound ETP-46321, a potent PI3K inhibitor, previously reported by our group. The new generated compounds showed good in vitro potency and selectivity, proved to inhibit potently the

have meanings given in the description, and pharmaceutically-acceptable esters, amides, solvates or salts thereof, which compounds are useful in the treatment of diseases in which inhibition of a protein or lipid kinase (e.g. a PI3-K and/or mTOR) is desired and/or required, and particularly in the treatment of cancer or a proliferative disease.

The first aspect of the invention relates to a phosphoinositide 3-kinase inhibitor for use in the treatment or prevention of a disease or condition associated with the expression of peroxisome proliferator-activated receptor gamma coactivator 1-α (Pgc1α) and/or uncoupling protein 1 (Thermogenin/Ucp1) in brown adipocytes. The disease or condition may be positive energy imbalance-associated, for example, obesity, an obesity-associated disease or condition, steatosis and biological aging (performance aging). Another aspect of the invention provides the use of a phosphoinositide 3-kinase inhibitor for promoting weight loss in an individual.
Phosphoinositide-3-kinase (PI3K) is an important target for cancer therapeutics due to the deregulation of this signaling pathway in a wide variety of human cancers. Herein, we describe the optimization of imidazo [1,2-a] pyrazines, which allow us to identify compound 14 (ETP-46321), with potent biochemical and cellular activity and good pharmacokinetic properties (PK) after oral dosing. ETP-46321 PK/PD studies showed time dependent downregulation of AKT(Ser473) phosphorylation, which correlates with compound levels in tumor tissue and demonstrating to be efficacious in a GEMM mouse tumor model driven by a K-Ras(G12V) oncogenic mutation. Treatment with ETP-46321 resulted in significant tumor growth inhibition. (C) 2012 Elsevier Ltd. All rights reserved.
