Fragment-Based Approaches in Drug Discovery and Chemical Biology

Scott, Duncan E., Coyne, Anthony G., Hudson, Sean A., Abell, Chris·2012·Biochemistry

Abstract

Fragment-based approaches to finding novel small molecules that bind to proteins are now firmly established in drug discovery and chemical biology. Initially developed primarily in a few centers in the biotech and pharma industry, this methodology has now been adopted widely in both the pharmaceutical industry and academia. After the initial success with kinase targets, the versatility of this approach has now expanded to a broad range of different protein classes. Herein we describe recent fragment-based approaches to a wide range of target types, including Hsp90, β-secretase, and allosteric sites in human immunodeficiency virus protease and fanesyl pyrophosphate synthase. The role of fragment-based approaches in an academic research environment is also examined with an emphasis on neglected diseases such as tuberculosis. The development of a fragment library, the fragment screening process, and the subsequent fragment hit elaboration will be discussed using examples from the literature.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

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?

  • FBLD has been mostly limited to the study of purified proteins in vitro due to the generally low affinity of fragment hits and the biophysical methods typically used for their discovery.

    “However, due to the generally low affinity of fragment hits and the biophysical methods typically used for their discovery (e.g., NMR, surface plasmon resonance, isothermal calorimetry), FBLD has been mostly limited to the study of purified proteins in vitro11.”
  • Fragment-based ligand discovery (FBLD) has emerged as a versatile approach for the discovery of atom-efficient, small-molecule binders for a wide range of proteins.

    “Fragment-based ligand discovery (FBLD) has emerged as a versatile approach for the discovery of atom-efficient, small-molecule binders for a wide range of proteins10–12.”

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.
