many G protein-coupled receptors (GPCRs). Amiloride 1 and 5-(N,N-hexamethylene)amiloride 2 (HMA) supposedly bind in this sodium ion site and can influence orthosteric ligand binding. The availability of a high-resolution X-ray crystal structure of the human adenosine A2A receptor (hA2AAR), in which the allosteric sodium ion site was elucidated, makes it an appropriate model receptor for investigating the
A novel structural class of potent inhibitors of NF-κB activation: structure–activity relationships and biological effects of 6-aminoquinazoline derivatives
In this study, we have investigated the roles of substituents on the terminal phenyl ring at the C(4)-position of the quinazoline core to complete the structure-activity relationships (SARs) of our NF-kappaB activation inhibitors. Among them, compound 12j afforded highly potent inhibitory activity toward NF-kappaB transcriptional activation with IC50 value of 2nM, along with an excellent in vivo efficacy by reducing the edema formation seen in carrageenin-induced inflammation of the rat hind paw.

Multicomponent, fragment-based synthesis of polyphenol-containing peptidomimetics and their inhibiting activity on beta-amyloid oligomerization
strategy to develop new chemical entities to be used as prevention or therapy for Alzheimer's disease. Some of the members of this library have demonstrated, in thioflavin assays, a highly promising activity in inhibiting aggregation for two β-amyloid peptides: Aβ1-42 and the truncated AβpE3-42.
