The Targeted AHR Modulator Library is a curated chemical screening set designed to accelerate the discovery of novel small-molecule modulators of the aryl hydrocarbon receptor (AHR) — a ligand-dependent transcription factor with key roles in immunity, cancer, inflammation, and xenobiotic metabolism.

This unique compound library supports early-stage discovery, target validation, and therapeutic innovation by providing access to structurally diverse and computationally prioritized molecules tailored for AHR-centric research and drug development programs.

SuFEx (Sulfur-Fluoride Exchange) Chemistry represents the next-generation approach to covalent drug discovery, chemical biology, and synthetic chemistry. Building on the principles of click chemistry, SuFEx reactions leverage the unique S(VI)–F bond, allowing precise and high-yielding chemical transformations under mild conditions.

OTAVA, in collaboration with Melius Organics, introduces a comprehensive SuFEx Handle Fragment Library, a diverse collection of aryl fluorosulfates and sulfamoyl fluorides designed to expand the druggable proteome, enhance covalent drug development, and facilitate advanced chemical synthesis.
