Tethering: Fragment-Based Drug Discovery
Abstract
▪ Abstract The genomics revolution has provided a deluge of new targets for drug discovery. To facilitate the drug discovery process, many researchers are turning to fragment-based approaches to find lead molecules more efficiently. One such method, Tethering 1 , allows for the identification of small-molecule fragments that bind to specific regions of a protein target. These fragments can then be elaborated, combined with other molecules, or combined with one another to provide high-affinity drug leads. In this review we describe the background and theory behind Tethering and discuss its use in identifying novel inhibitors for protein targets including interleukin-2 (IL-2), thymidylate synthase (TS), protein tyrosine phosphatase 1B (PTP-1B), and caspases.

“The inhibitor (compound 12 in their study) was discovered through a disulfide-fragment screening approach known as tethering, whereby a library of 480 disulfide fragments was screened against KRAS(G12C) in the GDP-bound state using intact protein mass spectrometry (MS)88,90.”

In the citing paper
“Originally, MS-based compound screening grew out of ‘tethering’, which is a technique employed since 2000 that uses libraries of compounds linked to disulfides to identify fragments that bind cysteine-adjacent pockets90,147.”

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.
