“The REAL Space comprises 21 billion make-on-demand molecules and is currently the largest offer of commercially available compounds. The REAL compounds in the Space are assembled via more than 170 well-validated parallel synthesis protocols applied to over 112 000 qualified reagents and building blocks.” 129K reagents => 91K and 41K 1-synthons and 2-synthons + 24 possible reactions = 28 trillion genes 2-synthon 1-synthons

CB can't find all the molecules that FTrees found For the ones CB finds we pick the enantiomer with the best score and update the catalog ID. For the rest we use the catalogue ID that FTree provided with unknown chirality (51) New 150 short list 149 short list (submitted) Check for duplicates Total price < $10K 77 short list (submitted)
good docking score The molecules found by Synthon-GA are generally not similar to those available in library While the synthons are known the combination rules are proprietary Combination rules could probably be “reverse engineered” with ML Experimental verification is underway Regular GA penalises chiral molecules Are Synthon GA molecules easier to synthesize?
