- Design, synthesis, and pharmacological evaluation of fused β-homophenylalanine derivatives as potent DPP-4 inhibitors
-
Dipeptidyl peptidase-4 (DPP-4) inhibitors are accepted as a favorable class of agents for the treatment of type 2 diabetes. Herein, a series of fused β-homophenylalanine derivatives as novel DPP-4 inhibitors were designed, synthesized, and evaluated for their inhibitory activities against DPP-4. Most of them displayed excellent DPP-4 inhibitory activities and good selectivity. Among them, 9aa, 18a, and 18m also showed good efficacy in an oral glucose tolerance test (OGTT) in ICR mice. Moreover, when dosed 8 h prior to glucose challenge, 18m showed significantly greater potency than sitagliptin. It thus provides potential candidates for the further development into potent drugs targeting DPP-4.

- Benzylic brominations with N-bromosuccinimide in (Trifluoromethyl)benzene
-
A variety of benzylic brominations were performed by using N-bromosuccinimide in (trifluoromethyl)benzene with photochemical activation in the presence of 2,2′-azobisisobutyronitrile, 1,1′- azobis(cyclohexanecarbonitrile), or benzoyl peroxide as the radical initiator. This system provides clean, rapid, and high-yielding reactions with replacement of conventional solvents, such as tetrachloromethane, by less-toxic (trifluoromethyl)benzene.
