- Design and synthesis of tetrahydropyridopyrimidine derivatives as dual GPR119 and DPP-4 modulators
-
Based on the approach of merged pharmacophores of GPR119 agonists and DPP-4 inhibitors, a series of tetrahydropyridopyrimidine compounds were designed as dual GPR119 and DPP-4 modulators with hypoglycemic activity. Seven fragments extracted from DPP-4 inhibitors were hybridized with the scaffold of tetrahydropyridopyrimidine. Among them, compound 51 displayed most potent GPR119 agonistic activity (EC50 = 8.7 nM) and good inhibition rate of 74.5% against DPP-4 at 10 μM. Furthermore, the blood glucose AUC0-2h of 51 was reduced to 19.5% in the oral glucose tolerance test (oGTT) at the dose of 30 mg/kg in C57BL/6N mice, which was more potent than that of vildagliptin (16.4%) at the same dose. The docking study of compound 51 with DPP-4 indicated GPR119 agonists could inhibit DPP-4 to serve as dual GPR119 and DPP-4 modulators.

- Synthesis and evaluation of novel fused pyrimidine derivatives as GPR119 agonists
-
A novel series of fused pyrimidine derivatives were designed, synthesized and evaluated as GPR119 agonists. Among them, cyclohexene fused compounds (tetrahydroquinazolines) showed greater GPR119 agonistic activities than did dihydrocyclopentapyrimidine and tetrahydropyridopyrimidine scaffolds. Analogues (16, 19, 26, 28, 42) bearing endo-N-Boc-nortropane amine and fluoro-substituted aniline exhibited better EC50 values (0.27–1.2 μM) though they appeared to be partial agonists.

- Novel symmetrical trans-bis-Schiff bases of N-substituted-4- piperidones: Synthesis, characterization, and preliminary antileukemia activity mensurations
-
A series of novel symmetrical trans-bis-Schiff bases (11a, 11b, 11c, 11d, 11e, 11f, 11g, 11h, 11i, 11j, 11k, 11l, 11m) were designed and prepared as novel anticancer analogues, with the trans-configuration confirmed by X-ray diffraction. Preliminary inhibitory effects of these compounds on CML K562 cell growth were investigated, and the potential analogue 11e showed an excellent anti-leukemia activity (IC50=6.35 μg/mL), which is higher than that of the clinical drug 5-fluorouracil (IC50=8.48 μg/mL). Complete assignments had been achieved for the title compounds by spectroscopic techniques, and their structure-activity relationships have been studied.
