Focused On-demand Libraries - Receptor.AI Collaboration


Explore the Potential with AI-Driven Innovation

The focused library is created on demand with the latest virtual screening and parameter assessment technology, supported by the Receptor.AI drug discovery platform. This method is more effective than traditional methods and results in higher-quality compounds with better activity, selectivity, and safety.


The compounds are cherry-picked from the vast virtual chemical space of over 60B molecules. The synthesis and delivery of compounds is facilitated by Reaxense.


The library includes a list of the most promising modulators annotated with 38 ADME-Tox and 32 physicochemical and drug-likeness parameters. Also, each compound is presented with its optimal docking poses, affinity scores, and activity scores, providing a comprehensive overview.


We use our state-of-the-art dedicated workflow for designing focused libraries for enzymes.

It includes comprehensive molecular simulations of the catalytic and allosteric binding pockets and the ensemble virtual screening accounting for their conformational mobility. In the case of designing modulators, the structural changes induced by reaction intermediates are taken into account to leverage activity and selectivity.


Our library distinguishes itself through several key aspects:


  • The Receptor.AI platform integrates all available data about the target protein, including past experiments, literature data, known ligands, structural information and more. This consolidated approach maximises the probability of prioritising highly relevant compounds.

  • The platform uses sophisticated molecular simulations to identify possible binding sites so that the compounds in the focused library are suitable for discovering allosteric inhibitors and the binders for cryptic pockets.

  • The platform integrates over 50 highly customisable AI models, which are thoroughly tested and validated on a multitude of commercial drug discovery programs and research projects. It is designed to be efficient, reliable and accurate. All this power is utilised when producing the focused libraries.

  • In addition to producing the focused libraries, Receptor.AI provides services and end-to-end solutions at every stage of preclinical drug discovery. The pricing model is success-based, which reduces your risks and leverages the mutual benefits of the project's success.

UPID:
HS3S4_HUMAN

ALTERNATIVE NAMES:
Heparan sulfate D-glucosaminyl 3-O-sulfotransferase 4

ALTERNATIVE UPACC:
Q9Y661; Q5QI42; Q8NDC2

BACKGROUND:
The enzyme Heparan sulfate glucosamine 3-O-sulfotransferase 4 is instrumental in the sulfation of heparan sulfate, a critical component of the extracellular matrix. By transferring a sulfo group to an N-unsubstituted glucosamine linked to a 2-O-sulfo iduronic acid unit, it plays a distinct role from its homologs, such as 3-OST-1, by not converting heparan sulfate into an anticoagulant form.

THERAPEUTIC SIGNIFICANCE:
The exploration of Heparan sulfate glucosamine 3-O-sulfotransferase 4's function offers a promising avenue for drug discovery. Its unique mechanism of action in heparan sulfate modification without inducing anticoagulant properties highlights its potential as a target for therapeutic intervention in diseases where heparan sulfate plays a key role.
