Abstract

Experimental and computational approaches to estimate solubility and permeability in discovery and development settings are described. In the discovery setting 'the rule of 5' predicts that poor absorption or permeation is more likely when there are more than 5 H-bond donors, 10 H-bond acceptors, the molecular weight (MWT) is greater than 500 and the calculated Log P (CLogP) is greater than 5 (or MlogP > 4.15). Computational methodology for the rule-based Moriguchi Log P (MLogP) calculation is described. Turbidimetric solubility measurement is described and applied to known drugs. High throughput screening (HTS) leads tend to have higher MWT and Log P and lower turbidimetric solubility than leads in the pre-HTS era. In the development setting, solubility calculations focus on exact value prediction and are difficult because of polymorphism. Recent work on linear free energy relationships and Log P approaches are critically reviewed. Useful predictions are possible in closely related analog series when coupled with experimental thermodynamic solubility measurements.

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

  • A clogP value of 4.7 typically results in low aqueous solubility and high metabolic clearance.

    “which typically results in low aqueous solubility and high metabolic clearance (Lipinski et al., 2001).”
  • L1 and L2 satisfy Lipinski's rules for BBB penetration and calculated logBB values, suggesting they should be capable of crossing the BBB.

    “Considering the restrictive Lipinski’s rules for BBB penetration (MW ≤ 450, clogP ≤5, hydrogen bond donors ≤ 5, hydrogen bond acceptors ≤ 10, polar surface area ≤ 90 Å2) and the calculated logBB values (Table S2), both L1 and L2 satisfy these requirements, suggesting that these compounds should be capable of crossing the BBB.”
  • PROTAC physicochemical property space generally falls beyond the rule of 5 owing to the bifunctional nature of the molecules.

    “In general, PROTAC physicochemical property space falls beyond the ‘rule of 5’ (refs59,60) owing to the bifunctional nature of the molecules.”

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.
