Niacin receptor G-coupled protein receptor 109A (GPR109A) is an important target protein of the treatment of cardiovascular diseases and disorders of lipid metabolism diseases. Since GPR109A is one membrane protein, the crystal structure of which has not been resolved, there are many challenges to drug design for the receptor. Based on the mouse PUMA-G crystal structure, the three-dimensional structure of GPR109A was built by using the homol. modeling method. The model was evaluated by using the Ramachandran Plot and Profile-3D, and the model was optimized with MMFF94 force field, membrane and method of loop, and finally one stabile model was obtained and 12 sites that might be the active sites in the optimal model were found. SYBYL-X2 software was used to build GPR109A pyrazole agonist drug mols., through the steepest descent method and the Conjugate gradient method to receive the most stable conformation of the small drugs mols. All the agonists were docked into each active site of the protein by Libdock method, receiving the interaction models. We analyzed the distribution of amino acid of each active site, and took 5-methyl-3-carboxylic acid as a reference drug mol. to explore the interaction force with each protein active site. This study has theor. significance in designing G-coupled protein receptor 109A pyrazole agonists.
