Toronto, Canada — April 2026 — Dalriada Drug Discovery today announced the public launch of iCLASS™, a live-cell chemoproteomics platform and databank designed to support target discovery and hit identification through proteome-wide measurement of small molecule–protein interactions directly in living cells.
The launch follows several years of scientific development and infrastructure investment, as well as pre-launch collaboration with early partners and beta users. Prior to public release, iCLASS has been applied across multiple discovery programs, contributing to outcomes ranging from validated hit identification through to development candidate nomination.
Dalriada acknowledges the collaborators, partners, and beta testers who contributed scientific feedback during early access phases, helping refine both the dataset and the practical applications of the platform in early-stage research workflows.
Dalriada introduced iCLASS publicly during Drug Discovery Chemistry 2026, reflecting the company’s continued focus on supporting innovation in small molecule discovery through experimentally grounded datasets.
Addressing a Key Challenge in Early Discovery
A significant portion of the proteome remains difficult to target using traditional approaches. Many discovery decisions continue to rely on data generated outside of living cellular systems, including recombinant proteins, biochemical assays, and predictive modeling. While these approaches provide important insight, translation into cellular context remains a common source of uncertainty in early programs.
iCLASS was developed to provide proteome-wide small molecule interaction data directly in live cells, enabling earlier insight into target engagement, selectivity, and ligandability across diverse protein classes, including proteins that may be difficult to evaluate using structure-based approaches alone.
The platform integrates chemoproteomics and multi-omics workflows to generate datasets that support evaluation of target tractability and identification of potential starting points for discovery programs.
The current iCLASS databank includes:
- 13,500+ proteins
- 100,000+ binding sites
- 30 million+ live-cell data points
These datasets enable identification of ligandable sites across the proteome, including cryptic pockets, allosteric regions, disordered proteins, and protein–protein interaction interfaces.
Expanding Access to Proteome-Wide Discovery Data
iCLASS provides researchers with an alternative hit-finding approach that has historically been difficult for many organizations to access. By enabling exploration of small molecule interactions directly in live cells, the platform supports earlier evaluation of target druggability and may help inform prioritization decisions in discovery programs.
The platform is available through databank access, collaborative data generation, and integrated discovery partnerships spanning target identification through early development.
Availability
iCLASS is now publicly available to researchers in biotechnology, pharmaceutical, and academic organizations.
