Discovery of DA-1229: A potent, long acting dipeptidyl peptidase-4 inhibitor for the treatment of type 2 diabetes
摘要:
A series of beta-amino amide containing substituted piperazine-2-one derivatives was synthesized and evaluated as inhibitors of dipeptidyl pepdidase-4 (DPP-4) for the treatment of type 2 diabetes. As results of intensive SAR study of the series, (R)-4-[(R)-3-amino-4-(2,4,5-trifluorophenyl)-butanoyl]-3-(t-butoxymethyl)-piperazin-2-one (DA-1229) displayed potent DPP-4 inhibition pattern in several animal models, was selected for clinical development.

[EN] A novel class of peptide nucleic acids are described which include a conjugate attached thereto. The peptide nucleic acids generally comprise ligands such as naturally occurring DNA bases attached to a peptide backbone through a suitable linker. [FR] Cette invention se rapporte à un nouvelle classe d'acides nucléiques peptidiques, qui contiennent un conjugué fixé à eux. Ces acides nucléiques peptidiques comprennent généralement des ligands tels que des bases d'ADN existant à l'état naturel, qui sont fixées à un squelette peptidique par un segment de liaison approprié.
