Abstract:
A series of 38 phthalazinone-triazole compounds were synthesized using Click chemistry to identify potential antidiabetic agents. These compounds were systematically tested for their ability to promote glucose transporter type 4 (GLUT4) translocation in skeletal muscle cells. Among the 38 derivatives, 11 compounds (i.e., 12k, 13a-13c, 13e-13i, 13s, and 13v) showed significant potential to stimulate GLUT4 translocation in skeletal muscle cells, with compound 13a exhibiting most promising activity. Further, treatment with 13a induced a concentration-dependent increase in GLUT4 translocation in L6 skeletal muscle cells through the activation of wortmannin-sensitive PI-3-K-dependent signaling and AMPK-dependent signaling pathways. The in vivo studies further demonstrated that compound 13a effectively lowered blood glucose levels in STZ-induced diabetic rats and displayed favorable pharmacokinetic properties, making it a promising candidate for further development as an antidiabetic agent.
