structures as 5-hydroxy-5-trifluoromethylpyrazolines, a series of analogues was prepared via thermal condensation reactions between substituted acylhydrazones and trifluoromethyl 1,3-dicarbonyl arenes. Structure-activity relationship (SAR) studies showed that small lipophilic substituents at the 2- and 3-positions of the RHS and 2-, 3- and 4-postions of the LHS terminal benzene rings improved activity

needed to be developed. Dipeptidylpeptidase-4 (DPP-4) inhibitors are becoming increasingly important in the T2DM treatment due to the favorable properties. In the present study, a series of new substituted dihydropyrido [4′,3′:3,4] pyrazolo [1,5-a] pyrimidin-9(10H)-yl)-2-(2,5-difluorophenyl)tetrahydro-2H-pyran-3-amine were designed and synthesized as potent DPP-4 inhibitors. All compounds were characterized

are as defined hereinabove. The present invention also relates to a process for their preparation, a pharmaceutical composition containing said derivatives and a method of treating or preventing acute or chronic neurological disorder comprising administering to a patient in need of such treatment a pharmaceutical composition comprising a therapeutically effective amount of at least one such derivatives. These disorders include acute and chronic disorders
