CDN prodr_ug-1

CDN prodr-ug-1 (Compound 2) is a STING ligand. CDN prodr-ug-1 consists of a cyclic dinucleotide (CDN) and a dialanine peptide linker. CDN prodr-ug-1 can be cleaved following internalization into endolysosomes by cathepsins and subsequently release the parent CDN. CDN prodr-ug-1 can be used for synthesis nanoparticles for dr-ug delivery research[1].
