Our company is currently offering about 100 new quaternary ammonium salts that could be of interest to your research. All quaternary ammonium salts are in stock, and a full list of the salts in our catalog is available upon request.

Synthetic experience of Otava chemists allows to carry out custom syntheses of even more complex structures of quaternary ammonium salts at a reasonable price.

In recent years, structured RNAs have become tractable drug targets, enabling the discovery of selective modulators for riboswitches, long noncoding RNAs, G-quadruplexes, and RNA–protein complexes.
Breakthrough advances in library design, screening methodologies, and AI-based prioritization have expanded the scope of RNA-targeted drug discovery (Kovachka et al., Nat Rev Chem 2024; Lundquist et al., SLAS Discovery 2025; Morishita, ChemMedChem 2022; Momentum Bio, 2024).
Modern RNA-focused screening now combines:

• Affinity Selection–Mass Spectrometry (AS-MS) for label-free, solution-phase discovery,

• SPR/BLI for kinetic profiling and specificity ranking,

• AI-guided virtual enrichment to prioritize compounds with high “RNA-likeness” before experimental testing (Graff et al., Chem Sci 2020; Cao et al., Nat Mach Intell 2023).
