Targeting biomolecules with reversible covalent chemistry

Open access
Bandyopadhyay, Anupam, Gao, Jianmin·2016·Current Opinion in Chemical Biology

Abstract

Interaction of biomolecules typically proceeds in a highly selective and reversible manner, for which covalent bond formation has been largely avoided due to the potential difficulty of dissociation. However, employing reversible covalent warheads in drug design has given rise to covalent enzyme inhibitors that serve as powerful therapeutics, as well as molecular probes with exquisite target selectivity. This review article summarizes the recent advances in the development of reversible covalent chemistry for biological and medicinal applications. Specifically, we document the chemical strategies that allow for reversible modification of the three major classes of nucleophiles in biology: thiols, alcohols and amines. Emphasis is given to the chemical mechanisms that underlie the development of these reversible covalent reactions and their utilization in biology.

Claims other papers make about this one

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

  • Nitriles are more reversible than acrylamides because thiol elimination from the thioimidate adduct is easy.

    “the ease of thiol elimination from the thioimidate adduct makes nitriles more reversible than some other electrophiles, such as acrylamides104.”

    From Advances in covalent drug discovery (2022) · cites this paper as [104]

  • Nitriles can covalently bind highly reactive nucleophiles.

    “Nitriles can covalently bind particularly reactive nucleophiles; however, the ease of thiol elimination from the thioimidate adduct makes nitriles more reversible than some other electrophiles, such as acrylamides104.”

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.
