Characterize with confidence by linking experimental data to each molecule
Small-molecule therapeutics need to be effective, safe, stable, and bioavailable. Signals One helps unify diverse types of experimental data into one coherent view.
- Customizable workflows supporting multiple levels of screening and data capture, from high-throughput screening to toxicology and PK/PD testing
- Link screening data directly to individual compounds and batches in Signals One for full traceability
- Visualize comparative results with native analytics including curve fitting, clustering, and PCA
Streamline data capture, comparison, and interpretation across your small molecule screening pipeline with Signals One.
Discover how Signals One supports small molecule screening
Advance the right candidates with multiparameter confidence
Identify lead candidates and prioritize next steps with decision support that enables fast, evidence-based go/no-go decisions based on multiparameter optimization and structure-activity relationship (SAR) insights, including properties such as potency, selectivity, solubility, permeability, protein binding, clearance and tolerability.
- Use Spotfire analytics in Signals One to compare compound profiles across key attributes
Compare compounds across multiple attributes with multiparameter optimization (MPO) and insights from SAR to find “Goldilocks” candidates - Run automated PCA and clustering to identify trends across assays and candidates
- Make transparent go/no-go decisions faster with all your data in one place
Turn your molecular data into momentum with clear, confident decisions.
