Focused On-demand Library for General transcription and DNA repair factor IIH helicase subunit XPB

Focused On-demand Libraries - Reaxense Collaboration

Explore the Potential with AI-Driven Innovation

The specialised, focused library is developed on demand with the most recent virtual screening and parameter assessment technology, guided by the Receptor.AI drug discovery platform. This approach exceeds the capabilities of traditional methods and offers compounds with higher 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 our partner 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 in-depth molecular simulations of both the catalytic and allosteric binding pockets, with ensemble virtual screening focusing on their conformational flexibility. For modulators, the process includes considering the structural shifts due to reaction intermediates to boost activity and selectivity.

Several key aspects differentiate our library:

Receptor.AI compiles an all-encompassing dataset on the target protein, including historical experiments, literature data, known ligands, and structural insights, maximising the chances of prioritising the most pertinent compounds.
The platform employs state-of-the-art molecular simulations to identify potential binding sites, ensuring the focused library is primed for discovering allosteric inhibitors and binders of concealed pockets.
Over 50 customisable AI models, thoroughly evaluated in various drug discovery endeavours and research projects, make Receptor.AI both efficient and accurate. This technology is integral to the development of our focused libraries.
In addition to generating focused libraries, Receptor.AI offers a full range of services and solutions for every step of preclinical drug discovery, with a pricing model based on success, thereby reducing risk and promoting joint project success.

Background:

The General transcription and DNA repair factor IIH helicase subunit XPB, encoded by the gene P19447, plays a pivotal role in DNA repair and transcription. As part of the TFIIH core complex, it is crucial for nucleotide excision repair (NER) and RNA transcription by RNA polymerase II. Its ATP-dependent 3'-5' DNA helicase activity facilitates the opening of DNA around lesions for repair and is essential for transcription initiation.

Therapeutic significance:

Given its involvement in Xeroderma pigmentosum complementation group B and Trichothiodystrophy 2, photosensitive, understanding the role of General transcription and DNA repair factor IIH helicase subunit XPB could open doors to potential therapeutic strategies. Targeting its function in DNA repair and transcription initiation offers a promising avenue for treating these genetic disorders.
