Peptic ulcer disease is one of the major challenges in public health globally and new evidence shows that it can be controlled by targeting the histamine H receptor (H R). Recently, a number of H R antagonists have been synthesized and used to block the action of histamine on the parietal cells in the stomach and decrease the acid production. In this study, we modeled the H R by homology modeling using the 3-D crystal structure and this model was validated based on free energy and amino acid residues present in the allowed regions of a Ramachandran plot. We used this 3-D model for screening of highly potent drugs using molecular docking. We found cimetidine, cimetex, and famotidine as the most potent drugs based on the binding affinity of drug-protein interactions. We also generated a cellular network for H R that could be useful for better understanding of cellular mechanism and drug targets. These findings provide a new insight into the development of suitable, specific, and effective anti-ulcer drugs for a most effective treatment of ulcerous diseases.
