Donidalorsen
Based on 1 Customer Validation
Donidalorsen (ISIS-721744; IONIS-PKK-LRX free acid) is an antisense oligonucleotide targeting prekallikrein (PKK). Donidalorsen inhibits kallikrein activity and reduces the production of Bradykinin (HY-P0206) by specifically binding to and degrading PKK mRNA in the liver. Donidalorsen can be used in the research of hereditary angioedema.

Biological Activity
Donidalorsen binds selectively to hepatic prekallikrein mRNA, mediates its degradation via ribonuclease H1, reduces hepatic prekallikrein production, reduces plasma prekallikrein concentrations, reduces plasma D-dimer concentrations, inhibits prekallikrein protein production, and reduces hereditary angioedema attack frequency[1].
