Fig. 3From: Similar compounds versus similar conformers: complementarity between PubChem 2-D and 3-D neighboring setsExamples of compounds in the Drug-(A) set that have a strong preference for one neighboring method over the other. Compounds in the Drug-(A) set with the most 2-D neighbors and no 3-D neighbors and compounds with the most 3-D neighbors and no 2-D neighbors. Note that all the compounds with 2-D-only neighbors have multiple covalent unitsBack to article page
