Martin Shkreli (yes, that Martin Shkreli) is currently running a virtual screen for additional PCNA inhibitors: https://twitter.com/wagieeacc/status/1687137621699436552

Can you explain what's going on there? Sounds like he's doing something to prevent patenting of drugs but I don't follow what it is.

Virtual screening[1] is a computational technique where you take an experimentally resolved structure of a protein (PCNA in this case) and sequentially dock a large amount of different compounds to see which ones of them bind favorably to the target protein. It is worth mentioning that virtual screening is a very early step in a drug discovery pipeline. These hits need to be characterized and validated experimentally to see if there is an actual effect.

I am not well-versed in intellectual property (so please correct me if I’m wrong), but in this case Shkreli is using a database of commercially available compounds (ZINC) and a hit present in the screen could be patented. He said he won’t do it, and, since this could be considered prior art, nobody else can do a claim.
