Technical Notes
LogD7.4
Sygnature Discovery’s LogD7.4 validation confirms the assay’s accuracy and reproducibility across a wide range of compound lipophilicities. Using a classical shake‑flask approach with LC–MS/MS quantification, the method shows strong alignment with literature values and low variability across repeat assays, providing high‑quality lipophilicity data to support confident early‑stage ADME decision‑making.
Technical Notes
ChromLogD
Sygnature Discovery’s ChromLogD validation demonstrates a fast and reliable chromatographic approach for determining lipophilicity, with excellent reproducibility across inter‑ and intra‑assay experiments. The method offers a practical, high‑throughput alternative to shake‑flask assays, supporting confident ADME decision‑making in early drug discovery.
Technical Notes
EPSA
Sygnature Discovery’s EPSA validation demonstrates a fast and reliable SFC‑MS method for estimating exposed polar surface area and understanding how effectively compounds can shield polarity. With optimized chromatography, consistent retention times and strong reproducibility, the assay supports rapid permeability assessment—especially valuable for bRo5 molecules and bifunctional degraders.
