ZINC-22 rearrangement of May-2024

This is our first news report for a long time. == DRAFT ==

• We have released a new layer /zinc-22w/, Enamine macrocycles. There are about 5000 macrocycles. We have no idea whether these are any good for docking. Please let us know. Unusually, we have allowed up to H39, whereas for small molecules we only load and build up to H29.

• We have begun to release a new layer, /zinc-22y/. This is an incremental update. What we did was to take all the molecules in 2D registered in ZINC and ask how many of these are _not_ available in 3D ready to dock formats. We found about billions of such molecules, even just up to H24. We have begun to process them and make them available. We are currently complete up to H15. H16 and H17 are well underway. H18 and H19 have started to appears. H20 and H21 are still in the building stage, and H22, H23 and H24 have not started to be built. We will attempt to process everything up to H24, while at the same time, we attempt to finish H25-H29 in the first generation, represented mostly by /zinc-22x/ and /zinc-22n/.

• We have updated 2D molecule counts in ZINC-22. Thus the 2D browser is now a pretty correct summary of what we have loaded. (It is working on H25 as I write, expecting to finish H26-H29 later today). ZINC-22 2D is now about 30% bigger. Old count was around 37B. Now around 50B.

• We have rearranged Smallworld and Arthor databases. The information is here: Smallworld_and_Arthor_Databases

There are five of each, thus: sw (public, no pw), swp (private, pw, but available), swcc (chemistry commons), swbb (building blocks) and one more that is private to UCSF. For Arthor it is the same thing: arthor, arthorp, arthorcc, arthorbb and a UCSF only one.

• We have been building and updating 3D tranches for about a year, and are now starting to push them to public servers.

This will happen over the coming weeks and we will announce when it is done.

• There have been a lot of bug fixes in Cartblanche22.docking.org. It is much more reliably now than earlier versions. If you had trouble with it, please try again.

• new SDI files in /zinc-22x/sets/ as of 2024-05-16
