Discovery of novel 2-[2-(3-hydroxy-pyridin-2-yl)-thiazol-4-yl]-acetamide derivatives as HIF prolyl 4-hydroxylase inhibitors; SAR, synthesis and modeling evaluation

The design, synthesis, and capacity to inhibit HIF prolyl 4-hydroxylases (PHDs) are described for 2-[2-(3-hydroxy-pyridin-2-yl)-thiazol-4-yl]-acetamide analogs. These analogs revealed two kinds of novel scaffolds as PHD2 inhibitors. Synthetic routes were developed for the preparation of their analogs containing the new scaffolds. In addition, the structure–activity relationship (SAR) of the 2-[2-(3-hydroxy-pyridin-2-yl)-thiazol-4-yl]-acetamide derivatives and their biological activities were reported. The complex structure of compound 18 with PHD2 was also obtained for the purpose of more efficient lead optimization.
