A series of 1,3-disubstituted-pyridin-4（1H）-one derivatives were synthesized. The results of a viability assay on NIH_T3 cells indicated that compound 3m potently inhibited the cell viability with an IC50 value of 2.0 μM. The 3D-quantitative structure-activity relationship analyses of 30 final molecules applying topomer CoMFA and AutoGPA methods gave two reasonable models with a cross-validated correlation coefficient q^2 of 0.662 and 0.787, respectively. The achievement herein suggested the application of 3-hydroxypyridin-4（1H）-one as a novel scaffold for the discovery of anti-fibrosis agents. In addition, the QSAR and pharmacophore models established with the activity data may provide new insights into the structure optimization of pyridin-4（1H）-one derivative with potent anti-fibrotic effects.
