A(2A) adenosine receptor (A(2A)AR) antagonists are considered to be useful in cancer immunotherapy and vaccines and as potential drugs for the treatment of Parkinson's disease. To better understand the chemical features responsible for the recognition mechanism and the receptor-ligand interaction, we performed the molecular docking study using selective A(2A)AR antagonists and combined with a pharmacophore based virtual library screening. The putative binding mode for the antagonists served as the templates for pharmacophore modeling and a virtually generated library have been screened for novel A(2A)AR antagonist development.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
