Synthesis and antidiabetic performance of β-amino ketone containing nabumetone moiety
摘要:
We wish to report the further design and improved synthesis that resulted in two series of target molecules, TM-1 and TM-2, with remarkably simplified structures containing beta-amino ketone of discrete nabumetone moiety. These were obtained via a 'one-pot, two-step, three-component' protocol of Mannich reaction with yield up to 97%. A total of 28 out of 31 new compounds were characterized using H-1 NMR, C-13 NMR, ESI MS and HRMS techniques. Studies on their antidiabetic activities, screened in vitro at 10 mu g mL (1) level, indicate that TM-2 possesses peroxisome proliferator-activated receptor activation and alpha-glucosidase inhibition activity significantly stronger than that of TM-1, and also that of the series B compounds that were previously synthesized by the group. Analysis of the structure-activity relationship points to the sulfanilamide unit as the most probable potent group of b-amino ketone and, on the basis of which, a tangible strategy is presented for the development of new antidiabetic drugs.
