RxPlorer™

Exploiting Protein Metastates to Drug the Undruggable

Metastate Discovery Platform

RxPlorer™ is a new technology for finding small molecule hits, particularly against challenging, previously undruggable targets. Leveraging advanced molecular dynamics,  RxPlorer™ uncovers protein metastates and reveals novel binding sites in difficult to target proteins.

By combining RxPlorer™ with our in vitro capabilities, RxCelerate can deliver rapid hit identification and screening in 2 months.

Redefining drug discovery through metastable-state exploration

RxPlorer™ explores the full folding landscape of a target to expose hidden, short-lived and cryptic pockets that do not appear in static crystal structures. By revealing these transient binding opportunities, known as metastates, we can provide clients with high value starting points for small molecule binders, allosteric inhibitors and monovalent degraders across challenging protein targets.

The discovery process uses a unique combination of methods: advanced molecular dynamics, steered accelerated dynamics, free energy calculations and machine learning informed docking of large chemical spaces. This approach allows us to explore and characterise large, complex conformational landscapes and to prioritise pockets with the highest potential for ligand binding and downstream functional impact. The RxPlorer™ platform was developed by the computational scientists at ProsaRx, RxCelerate’s in silico design and discovery arm.

FAST Hit Discovery Campaigns

RxPlorer™ is our new technology for finding small molecule hits, particularly against challenging, previously undruggable targets. Leveraging advanced molecular dynamics,  RxPlorer™ uncovers protein metastates and reveals novel binding sites in difficult to target proteins.

RxPlorer™ is fully integrated with our in vitro capabilities allowing us to move at pace.  We can apply the RxPlorer™ platform and deliver hit data for a novel target in two months.

Case study: RxPlorer has successfully generated novel hits for Eotaxin-1

Studies in Eotaxin-1 (CCL11), a chemokine and key asthma target previously undrugged with small molecules, exemplify the capabilities of RxPlorer™. The team identified druggable metastates with binding pockets not visible in available static structures.  Focused virtual screening against these states generated multiple classes of hits, which were experimentally verified, validating the biological relevance of the metastates uncovered.

Early Adopter Programme

RxPlorer™ is currently available to clients through an early adopter programme, one of which has recently shown high hit rates on an intracellular protein target. RxCelerate is inviting organisations seeking rapid discovery of novel hits for challenging targets to get in touch.
