Influenza virus-IN-6 (Compound 35) is a potent inhibitor of the N-terminal domain of the polymerase acidic protein (PA N) endonuclease subunit of the influenza virus, with an inhibitory concentration 50 (IC 50) value of 0.20 μM [1].

APE1-IN-2 (compound AP1), a Pt(IV) proagent, selectively targets the essential base excision repair protein apurinic/apyrimidinic endonuclease 1 (APE1). Exhibiting anticancer properties, APE1-IN-2 prompts the intracellular accumulation of platinum and initiates the activation of DNA damage response and apoptosis pathways [1].

Ribonuclease T1 (Rnase T1), widely utilized in biochemical research, is an endonuclease targeting single-stranded RNA. It cleaves the phosphodiester bond between 3'-guanosine residues and adjacent nucleoside 5'-OH groups, thereby producing 3'-GMP terminal oligonucleotides, and forms nucleoside 2', 3'-cyclic phosphoric acid intermediates in the process [1].
