<h2>Curie Web Demo</h2>
|
||||
<p>Dock and Report performs molecular docking using AutoDock Vina, generates visualisations using PyMOL and then finds protein-ligand interactions using PLIP. It then compiles all of this into a PDF report and emails it to you.</p>
|
||||
<p>Curie-Web is a part of The Curie Project which aims to make the process of Computer-Aided Drug Design as fast as possible.</p>
|
||||
<p>The following are the currently active modules</p>

<li><a href="{{ url_for('status')}}">Job Status</a></li>
|

<li><a href="{{ url_for('generate') }}">Generate</a></li>
|
||||
<li><a href="{{ url_for('dock_upload') }}">Dock and Report (Manual)</a> - You can enter your AutoDock Vina configuration, upload the PDBQT files and it will perform the molecular docking and generate a PDF with proper visualisations and protein-interaction profillings (Using PLIP) </li>
|
||||
<li><a href="{{ url_for('dock_upload_single') }}">Dock and Report (Automatic)</a> - You just enter in the PDB Code, target compound's SMILES structure and name, it will automatically find a binding location and then perform docking and report generation</li>

</ul>
|

|

<h3>Drug Designing</h3>

<li><a href="{{ url_for('generate') }}">Generate</a> - You can use this to generate completely new compounds</li>

<h3>Researching</h3>
|

<ul>
|
||||
<li><a href="{{ url_for('pubmed') }}">PubMed Search</a> - Handy PubMed search with direct download links</li>
|
||||
<li>Qrious App - You can enter a question for a set of papers (e.g. ChemRxiv preprints) and it uses AI to answer it for each individual paper based on their abstract</li>
