- Design, synthesis, and biological evaluation of novel pan agonists of FFA1, PPARγ and PPARδ
-
The free fatty acid receptor 1 (FFA1) and peroxisome proliferator-activated receptors (PPARs) have attracted interest as potent targets for the treatment of metabolic syndrome such as type 2 diabetes. Based on the hypothesis that the dual agonists of PPARs and FFA1 would act as insulin sensitizers and secretagogues by simultaneous activation of PPARs and FFA1, we developed the design strategy to obtain dual PPARs/FFA1 agonist by hybrid FFA1 agonist 1 with PPARδ agonist 2 in consideration of their structural similarity. As expected, systematic exploration of structure-activity relationship and molecular modeling, results in the discovery of lead compound 15, a pan agonist with relative balanced activities between FFA1, PPARγ and PPARδ. The dose-response relationship studies suggested that the pan agonist 15 suppressed the excursion of blood glucose levels in a dose-dependent manner. During a 5-days treatment in ob/ob mice, the pan agonist 15 (100 mg/kg) revealed sustained hypoglycemic effect, even proximity to the most advanced FFA1 agonist (TAK-875, 40 mg/kg), which might be attributed to its pan PPARs/FFA1 activities to simultaneous regulate the mechanism of insulin secretion and resistance. These positive results suggest that the dual PPARs/FFA1 agonists such as lead compound 15 might be novel therapeutic strategy to modulate the complex pathological mechanisms of type 2 diabetes.

- Design, synthesis, docking studies and biological evaluation of novel dihydro-1,3,5-triazines as human DHFR inhibitors
-
A novel series of dihydro-1,3,5-triazine derivatives bearing a heteroatom spiro-ring were designed and synthesized on the basis of molecular flexible docking work, and their biological activities were evaluated. Compounds A2, A5, B1 and B3 showed potent human dihydrofolate reductase (hDHFR) inhibitory activity with IC50values of 7.46 nM, 3.72 nM, 6.46 nM, 4.08 nM, versus reference drug methotrexate (MTX). From the molecular docking result we concluded that the conformation space generated by deformation of the flexible residue Phe31 is favorable for the binding of the spiro-ring, and inserting heteroatom into spiro ring might increase the binding affinity. There were 24 compounds with broadspectrum antiproliferative activity against several tumor cell lines (HCT116, A549, HL-60, HepG2 and MDA-MB-231) with IC50values ranging from 0.79 to 0.001 μM. The antitumor activity in?vivo of compound A2 was determined in a human alveolar basal epithelial cell line A549 xenograft model. This study offered novel anticancer agents with high inhibitory activity that target hDHFR and have a binding mode of the novel molecular scaffold with hDHFR. This provides potent support for further development of novel hDHFR inhibitors.

- A novel nonpeptide HIV-1 protease inhibitor: Elucidation of the binding mode and its application in the design of related analogs
-
HIV-1 protease has been identified as a significant target enzyme in AIDS research. While numerous peptide-derived inhibitors have been described, the identification of a nonpeptide inhibitor remains an important goal. Using an HIV-1 protease mass screening technique, 4-hydroxy-3-(3-phenoxypropyl)-2H-1- benzopyran-2-one (1) was identified as a nonpeptide competitive inhibitor of the enzyme. Employing a Monte Carlo-based docking procedure, the coumarin was docked in the active site of the enzyme, revealing a binding mode that was later confirmed by the X-ray crystal analysis. Several analogs were prepared to test the binding interactions and improve the overall binding affinity. The most active compound in the study was 4,7-dihydroxy-3-[4-(2- methoxyphenyl)butyl]-2H-1-benzopyran-2-one (31).
