Abstract

Recently, 'tangible' virtual libraries have made billions of molecules readily available. Prioritizing these molecules for synthesis and testing demands computational approaches, such as docking. Their success may depend on library diversity, their similarity to bio-like molecules and how receptor fit and artifacts change with library size. We compared a library of 3 million 'in-stock' molecules with billion-plus tangible libraries. The bias toward bio-like molecules in the tangible library decreases 19,000-fold versus those 'in-stock'. Similarly, thousands of high-ranking molecules, including experimental actives, from five ultra-large-library docking campaigns are also dissimilar to bio-like molecules. Meanwhile, better-fitting molecules are found as the library grows, with the score improving log-linearly with library size. Finally, as library size increases, so too do rare molecules that rank artifactually well. Although the nature of these artifacts changes from target to target, the expectation of their occurrence does not, and simple strategies can minimize their impact.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • GANs have found applications in chemistry, such as the first deep learning GAN used in anti-cancer compound design.

    “GANs (95), inspired by game theory and deep learning, have found applications in chemistry, such as the first deep learning GAN used in anti-cancer compound design (96).”

    From Artificial Intelligence for Drug Discovery: Are We There Yet? (2024) · cites this paper as [95]

    The Introduction and Results discuss virtual screening libraries and molecular docking, not GANs. Searches for GANs, deep learning, and anti-cancer compound design found no passage addressing the claimed application or its priority. (LLM, conf=0.76)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
