We report herein the synthesis and structure-activity relationships (SAR) of a series of pyridazine derivatives with the activation of glucose transporter type 4 (GLUT4) translocation. Through a cell-based phenotype screening in L6-GLUT4-myc myoblasts and functional glucose uptake assays, lead compound 1a was identified as a functional small molecule. After further derivatization, the thienopyridazine scaffold as the central ring (B-part) was revealed to have potent GLUT4 translocation activities. Consequently, we obtained promising compound 26b, which showed a significant blood glucose lowering effect in the severe diabetic mice model (10-week aged db/db mice) after oral dosing even at 10 mg/kg, implying that our pyridazine derivatives have potential to become novel therapeutic agents for diabetes mellitus.

D051275 Glucose Transporter Type 4 A glucose transport protein found in mature MUSCLE CELLS and ADIPOCYTES. It promotes transport of glucose from the BLOOD into target TISSUES. The inactive form of the protein is localized in CYTOPLASMIC VESICLES. In response to INSULIN, it is translocated to the PLASMA MEMBRANE where it facilitates glucose uptake.
