8-Bromo-7-(2-butyn-1-yl)-3-methylxanthine (CAS: 666816-98-4) is an intermediate for Linagliptin (CAS: 668270-12-0). Linagliptin is an oral, highly selective inhibitor of dipeptidyl peptidase-4 and is the first agent of its class to be eliminated predominantly via a nonrenal route. Linagliptin is indicated for once daily use for the treatment of adults with type 2 diabetes mellitus.
