Based on the hybridization strategy of dominant fragments, a series of pyrimidine sulfonamide (PS) derivatives were obtained by combining the pharmacophore fragments (sulfonamide group and pyrimidine group) with different biological activities, and evaluated as a new type of anticancer drug. The compounds were evaluated for in vitro cytotoxicity against four human cancer cell lines (HeLa, HCT-116,
Identification of 4-benzylamino-2-[(4-morpholin-4-ylphenyl)amino]pyrimidine-5-carboxamide derivatives as potent and orally bioavailable STAT6 inhibitors
Signal transducers and activators of transcription 6 (STAT6) is a key regulator of the type 2 helper T (Th2) cell immune response and a potential therapeutic target for allergic diseases such as asthma and atopic diseases. To search for potent and orally bioavailable STAT6 inhibitors, we synthesized a series of 4-benzylaminopyrimidine-5- carboxamide derivatives and evaluated their STAT6 inhibitory activities. Among these compounds, 2-[(4-morpholin-4-ylphenyl)amino]-4-[(2,3,6- trifluorobenzyl)amino]pyrimidine-5-carboxamide (25y, YM-341619, AS1617612) showed potent STAT6 inhibition with an IC(50) of 0.70 nM, and also inhibited Th2 differentiation in mouse spleen T cells induced by interleukin (IL)-4 with an IC(50) of 0.28 nM without affecting type 1 helper T (Th1) cell differentiation induced by IL-12. In addition, compound 25y showed an oral bioavailability of 25% in mouse. (c) 2008 Elsevier Ltd. All rights reserved.

The iridium-catalysed enantioselectiveintramolecularallylicsubstitution of pyrimidine-tethered allylic carbonates was developed. A wide range of chiral pyrimidine-fused diazepinonederivatives were successfully constructed in 88–96% yields with 85–99% ees. This work further highlights the power of chiral-bridged biphenyl phosphoramidites in asymmetric synthesis.
