solid-phase syntheses of artificial β-sheets 1−4, which mimic the structure and hydrogen-bonding patterns of protein β-sheets. In these compounds, molecular templates induce β-sheet structures in attached peptide strands. The templates consist of di- and triurea derivatives, which hold peptide and peptidomimetic strands in proximity, and β-strandmimics, which hydrogen bond to the peptide strands. The syntheses
The invention relates to isoquinolin-3-ylurea derivatives of formula (I) wherein R1 represents (C1-C3)alkyl, (C1-C3)haloalkyl or cyclopropyl, R4 represents H and the substituents R2 and R3 and R5 have the meanings disclosed in the specification; and to the salts of such compounds. These compounds are useful for the prevention or the treatment of bacterial infections.
