Air- and moisture-tolerant, this (+)-PSI Reagent was developed in the Baran lab for stereocontrolled synthesis of phosphorothioate oligonucleotides. The enantiomer, (?)-PSI Reagent, is also available (cat# ALD00602).
The PSI Reagents open access to thiophosphate-based nucleotide molecules with therapeutic promise as demonstrated by the Baran lab in the preparation of pure stereoisomers of cyclic dinucleotides (CDNs) and antisense oligonucleotides (ASOs).
