Abstact

Synthesis and SAR are described for a structurally distinct class of DPP-IV inhibitors based on aminobenzo[a]quinolizines bearing (hetero-)aromatic substituents in the S1 specificity pocket. The m-(fluoromethyl)-phenyl derivative (S,S,S)-2g possesses the best fit in the S1 pocket. However, (S,S,S)-2i, bearing a more hydrophilic 5-methyl-pyridin-2-yl residue as substituent for the S1 pocket, displays excellent in vivo activity and superior drug-like properties.
