The present invention relates to Imidazolopyrimidine Analogs, methods of making Imidazolopyrimidine Analogs, compositions comprising an Imidazolopyrimidine Analog, and methods for treating or preventing a PI3K-related disorder comprising administering to a subject in need thereof an effective amount of an Imidazolopyrimidine Analog. The invention also relates to methods for treating or preventing mTOR-related disorders comprising administering to a subject in need thereof an effective amount of an Imidazolopyrimidine Analog.

Series of purine and pyrazolo[3,4-d] pyrimidine inhibitors of phosphatidylinositol-3-kinases (PI3K) have been prepared. The optimized purine inhibitors show good potency in a PI3K p110 alpha (PI3K-alpha) fluorescence polarization assay with good selectivity versus PI3K p110 gamma (PI3K-gamma) and the mammalian target of rapamycin (mTOR). The related pyrazolo[3,4-d]pyrimidines show potent PI3K-alpha and mTOR inhibition with good selectivity versus PI3K-gamma. Representative compounds showed activity in a cellular proliferation assay against Caco-2 colorectal, LoVo colorectal and PC3MM2 prostate adenocarcinoma cancer cells. Signaling through the PI3K pathway was confirmed via inhibition of phospho-AKT in MDA-361 cells. (C) 2009 Elsevier Ltd. All rights reserved.

human A1 adenosine receptor containing a new purine scaffold. To study the structure activity relationships of this new chemical series for adenosine receptors, a library of 24 purines was synthesized and tested in radioligand binding assays at human A1, A2A, A2B and A3 adenosine receptor subtypes. Fourteen molecules showed potent antagonism at A1, A3 or dual A1/A3 adenosine receptors. This purine scaffold
