Are you sure you need ZINC, not CHEMBL or PubChem?
But if yes, there are at least a couple of scripts to download ZINC data (not all because of limitations): https://github.com/shadmehr-gh/zinc_downloader + https://github.com/Metaphorme/zincDownloader + https://github.com/quantaosun/Zinc-Million
Or you can access to all compounds IDs from ZINC using this - https://github.com/iit-Demokritos/drug_id_mapping - and then make a query to download needed data by scpecific IDs.
Also maybe you would find thus useful - https://github.com/Sulstice/Uptime-Cheminformatics
Can i perform MD simulation with 5,000ps simulation time. I once a publication which they used only 2,200ps simulation time. The software they used was Biovia Discovery Studio suite.
Can i also increase the simulation time to 5,000ps and cite the article ?
