  • Several studies reported successful conversion of either a reversible ibrutinib scaffold or a different noncovalent analog derived from a previously published covalent BTK inhibitor into BTK degraders.

    “Subsequently, several studies reported successful conversion of either a reversible ibrutinib scaffold 42,43 or a different noncovalent analog derived from a previously published covalent BTK inhibitor 44,45 into BTK degraders.”
  • The C481S resistance mutation in BTK renders first-generation BTK inhibitors less effective.

    “particularly because of emergence of the C481S resistance mutation in BTK that renders first-generation BTK inhibitors less effective169,170.”

    From PROTAC targeted protein degraders: the past is prologue (2022) · cites this paper as [170]

  • P13I more effectively reduces viability of BTK-dependent wild-type and C418S BTK-expressing HBL-1 DLBCL cells compared to ibrutinib.

    “More importantly, P13I more effectively reduced the viability of BTK-dependent wild-type and C418S BTK-expressing HBL-1 DLBCL cells compared to ibrutinib [117].”
  • P13I efficiently degrades both wild-type and C418S BTK with DC50 values of 10 nM and 28 nM, respectively.

    “Rao’s group reported a BTK degrader, named P13I, which efficiently degraded both wild-type and C418S BTK with DC50 values of 10 nM and 28 nM, respectively.”

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.
