Phosphoinositide 3-kinases (PI3Ks) are regarded as promising targets for treatment of various cancers due to their roles in regulating cell proliferation, differentiation, migration, and survival. Here we report our efforts to develop potent and orally bioavailable PI3K inhibitors for the treatment of cancers. The alkylsulfonamide-containing quinazoline derivatives A1–A18 significantly inhibited PI3Kα, and cell proliferation among HCT-116, MCF-7 and SU-DHL-6 cell lines. The optimal compound A1 displayed potent inhibitory activity against PI3Kα (IC50 = 4.5 nM), PI3Kβ (IC50 = 4.5 nM), PI3Kγ (IC50 = 4.5 nM), PI3Kδ (IC50 = 4.5 nM) and significantly inhibited the growth of HCT-116, MCF-7 and SU-DHL-6 cell lines with IC50 values of 0.82 μM, 0.99 μM and 0.19 μM, respectively. Western blot analysis demonstrated A1 significantly suppressed the phosphorylation of AKTS473 in a dose-dependent manner. Furthermore, A1 could markedly inhibit cancer growth at the dose of 25 mg/kg in nude mouse HCT-116 xenograft model in vivo without causing significant weight loss or toxicity.
New tetracyclic 1,4-oxazepines constructed via practically simple tandem condensation strategy from readily available synthons

A streamlined synthetic methodology towards novel tetracyclic 1,4-oxazepines from readily available precursors is described. The compounds, designed as more soluble version of the earlier described, poorly soluble dibenzo[b,f][1,4]oxazepines, were obtained in high yields and as a single regioisomer as a result of three tandem chemical events - nucleophilic aromatic substitution, Smiles rearrangement and denitrocyclization.
Large-scale solvent-free chlorination of hydroxy-pyrimidines,-pyridines,- pyrazines and-amides using equimolar POCl3
Wang, Han,Wen, Kun,Wang, Le,Xiang, Ye,Xu, Xiaocheng,Shen, Yongjia,Sun, Zhihua
experimental part, p. 4533 - 4544 (2012/06/30)
Chlorination with equimolar POCl3 can be efficiently achieved not only for hydroxypyrimidines, but also for many other substrates such as 2-hydroxy-pyridines,-quinoxalines, or even-amides. The procedure is solvent-free and involves heating in a sealed reactor at high temperatures using one equivalent of pyridine as base. It is suitable for large scale (multigram) batch preparations.
[11C]GSK2126458 and [18F]GSK2126458, the first radiosynthesis of new potential PET agents for imaging of PI3K and mTOR in cancers

experimental part, p. 1569 - 1574 (2012/04/04)
GSK2126458 is a highly potent inhibitor of phosphoinositide 3-kinase (PI3K) and mammalian target of rapamycin (mTOR) with low picomolar to subnanomolar activity. [11C]GSK2126458 and [18F]GSK212 6458, new potential PET agents for imaging of PI3K and mTOR in cancer, were first designed and synthesized in 40-50% and 20-30% decay corrected radiochemical yield, and 370-740 and 37-222 GBq/lmol specific activity at end of bombardment (EOB), respectively.

Practical synthesis of a potent bradykinin B1 antagonist via enantioselective hydrogenation of a pyridyl N-acyl enamide
O'Shea, Paul D.,Gauvreau, Danny,Gosselin, Francis,Hughes, Greg,Nadeau, Christian,Roy, Amelie,Shultz, C. Scott
body text, p. 4547 - 4553 (2009/09/30)
(Chemical Equation Presented) A practical and efficient synthesis of bradykinin B1 antagonist 1 is described. A convergent strategy was utilized which involved synthesis of three fragments: 3, 6, and 7. Cross coupling of fragments 6 and 7 followed by amidation with 3 enabled efficient synthesis of 1 in 19 steps total, a 35% overall yield from commercially available pyridine 10. The key to the success of the synthesis was the development of a fluorodenitration step to install the fluorine in pyridine 7 and a catalytic enantioselective hydrogenation of N-acyl enamide 9 to set the stereochemistry.
