Herein, we describe a covalent fragmentscreen that identified the chloroacetohydrazide scaffold as a covalent UCHL1 inhibitor. Subsequent optimization provided an improved fragment with single-digit micromolar potency against UCHL1 and selectivity over the closely related UCHL3.
Fragment-based drug discovery (FBDD) was applied to cytochrome P450 3A4 reconstituted in Nanodiscs (NDs) with various lipid compositions. The choice of ND lipid influenced drug membrane interactions and fragment hit rates, demonstrating the critical role of the membrane environment in fragmentscreening for membrane proteins.
Integrated lead optimisation to advance APEIRON’s Cbl-b inhibitor development programme APN431; Inhibitors discovered at Domainex via virtual and fragmentscreening
Clustering FragmentScreening Hits With a Self-Organizing Map (SOM) In a paper, " Fragment binding to the Nsp3 macrodomain of SARS-CoV-2 identified through crystallographic screening and computational docking ", published last year by scientists from UCSF and the Diamond Light Source, the authors reported more than 200 structures of fragments bound (..)
Sygnature Discovery offers high throughput screening along with additional hit identification tools including virtual screening, knowledge-based design, and fragmentscreening.
In terms of compound libraries, we have a high-throughput screening library of about 200,000 ligands. For fragmentscreening, which are much smaller compounds, we have a library of about 3000 fragments. We can screen with many different formats and modalities.
Testing Claude’s Molecule Generation Ability To test the molecule generation ability of Claude, a general-purpose LLM from Anthropic, I prompted it to generate analogs for hits from fragmentscreens. These fragment hits are small molecules with between 11 and 21 heavy atoms.

Cryo-EM Expert microscopists in house and access to high end microscopes for screening and high resolution data collection (Glacios, Tecnai, Titan Krios). Fragment Based Drug Discovery Crystallographic fragmentscreening using a high solubility curated fragment library devoid of soluble aggregates.
A crystallographic fragmentscreen has been run against SARS-CoV-2 and a number of electrophilic fragments were screened using mass spectroscopy. These two screens serve as a launch pad for the COVID Moonshot which looks interesting (although I’d suggest easing off a bit on the propaganda).
In the fourth of his rules for air fighting , ‘Sailor’ Malan (readers may also be interested in his insights into fragmentscreening library design ) asserts that “height gives you the initiative” which can be adapted for drug design as “affinity gives you the initiative”.
We sampled several screening platforms in the course of our efforts, including fragmentscreening using ligand-observed nuclear magnetic resonance (NMR), DNA-encoded libraries (DEL), and SEC-MS. Each of these platforms is thoroughly vetted in protein world, but using them on RNA can yield surprising results.
It’s also worth mentioning that fragmentscreens have been run against SARS-CoV-2 Nsp3 macrodomain at UCSF and Diamond since there are no known inhibitors for this target.
Their world-class expertise in protein crystallography will enhance our fragmentscreening and analysis activities, as well as our structure-based drug design work.” Mark Abbott, CEO of Peak Proteins, commented: “We have always valued Sygnature Discovery’s support and are now really pleased to be joining them.

Our in-house team of NMR experts specialises in ligand binding experiments using proton or fluorine NMR, particularly effective for small molecule-biomolecule binding assays and fragmentscreening, where it excels in detecting mM affinity binders.
The second virtual screen focused on optimization of a hit from a previous crystallographic fragmentscreen. Fragment-to-lead optimization was guided by searches in a library of millions of compounds combined with docking screens to select the best candidate.
Paramin panorama Crystallographic fragmentscreens have been run recently against the main protease (at Diamond ) and the Nsp3 macrodomain (at UCSF and Diamond ) of SARS-Cov-2 and I thought that it might be of interest to take a closer look at why we screenfragments.
Screening covalent fragments against purified protein targets reduces the demands on the mass spectrometer with respect to absolute throughput, detection limit, and dynamic range.
Previously, covalent fragmentscreens yielded potent and selective compounds for individual kinases such as ERK1/2 but have not been applied to the broader kinome. Furthermore, many of the accessible cysteine positions have not been addressed so far.
Overall, we demonstrate that focused covalent fragmentscreening can be used to rapidly identify highly potent and selective electrophiles targeting bacterial serine hydrolases. This approach could be applied to other classes of lipid hydrolases in diverse pathogens or higher eukaryotes.
