8-Bromo-7-but-2-ynyl-3-methyl-1-(4-methyl-quinazolin-2-ylmethyl)-3,7-dihydro-purine-2,6-dione (CAS: 853029-57-9) is the parent nucleus of Linagliptin (CAS: 668270-12-0). Linagliptin (trade names Tradjenta and Trajetna) is an inhibitor of dipeptidyl peptidase-4 (DPP-4) that was approved by the U.S. FDA in May 2011 for the treatment of Type 2 diabetes along with diet and exercise. Linagliptin (BI-1356) has been described as a potent highly selective, slow-off rate and long acting inhibitor of DPP-4. Linagliptin arose from optimization efforts of xanthine-based DPP-4 inhibitors with the initial lead identified from an HTS campaign.
