Pharmacophore-based virtual Drug screening. weblink: https://pharmit.csb.pitt.edu/ Example Protein-Ligand complex: PDB ID: 4PPS Results -Example:https://pharmit.csb.pitt.edu/search.html Help or descriptions: https://pharmit.csb.pitt.edu/help.htm... Getting Started pharmit is a web server that facilitates virtual screening: it enables users to search for small molecules based on their structural and chemical similarity to another small molecule, with the goal of identifying those that bind to a target molecule (typically a protein receptor or enzyme). The search can take as input either a small molecule, a set of pharmacophore features (which will be subsequently described in greater detail), or both a protein and a pharmacophore or a small molecule for which a putative binding pose is known. This help follows the 4pps example, which the user may choose to follow simultaneously by clicking the link, or by other search initiation methods described below. From PDB A structure can be obtained directly from the PDB by entering its four-character PDB identifier in the first text box after "start from PDB" as shown in the figure below. To initiate the 4pps search using this method, the user may enter "4pps" in the box. A list of possible small molecules will be generated automatically in the second box, from which the user may choose a ligand of interest (ESE, in our case). Binding site waters may be excluded entirely, used as part of the ligand as optional pharmacophore features to include in the similarity search, or used as part of the receptor to identify which pharmacophore features of the ligand are relevant to binding (for our example, we will exclude them). To proceed with the search, the user should next choose "submit". Visualization After the desired structures are provided, pharmit will identify all pharmacophore features present in the ligand if a ligand structure rather than a pharmacophore query file was provided. If a receptor structure was provided, it will identify which of these features are relevant to the interaction between the protein-ligand pair using distance cutoffs between interacting features and will display only these interacting features. Database Selection When the user is satisfied with the query and constraints, a database to search should be selected by pressing the arrow next to the first button on the left sidebar. The options include CHEMBL20, ChemDiv, MolPort, NCI Open Chemical Repository, and PubChem, as well as several publicly available user-contributed libraries and any public or private libraries the user has personally submitted using the "create" menu accessible from the pharmit main page. Once a database is selected, pressing the search button initiates the search.
