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

Activité biologique
Description
In Vitro
Donidalorsen sodium 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].
