A series of N2,N4-disubstitutedquinazoline-2,4-diamines has been synthesized and tested against multidrug resistant Staphylococcus aureus. A structure–activity and structure–property relationship study was conducted to identify new hit compounds. This study led to the identification of N2,N4-disubstitutedquinazoline-2,4-diamines with minimum inhibitory concentrations (MICs) in the low micromolar
The design of a novel series of NPY-Y-5 receptor antagonists is described. Key elements for the design were the identification of weak Y-5 hits from a Y-1 program, results from a combinatorial approach and database mining. This led to the discovery of the quinazoline 4 and the aryl-sulphonamide moiety as major components of the pharmacophore for Y-5 affinity. The synthesis and SAR towards CGP71683A is described.
