Givosiran
Based on 1 publication(s) in Google Scholar
Givosiran (ALN-AS1) is a small interfering RNA that targets hepatic aminolevulinate synthase 1 (ALAS1) messenger RNA. Givosiran downregulates ALAS1 mRNA and prevents accumulation of neurotoxic δ-aminolevulinic acid (ALA) and porphobilinogen (PBG) levels. Givosiran demonstrates potent inhibitory activity against ALAS1 in mouse, rat, and cynomolgus monkey models. Givosiran can be used for the research of acute hepatic porphyria (AHP).

Biological Activity
Givosiran (3 mg/kg, s.c., twice weekly for 3 weeks) exhibits complete preventive effect in the rat acute intermittent porphyria (AIP) model[2].
Givosiran (20 mg/kg, s.c., single dose) works faster and has stronger inhibition than standard Hemoglobin (HY-P2995) treatment in mice[2].
Givosiran (1-10 mg/kg, s.c., single dose or once daily for 8 weeks) reduces serum and urinary ALAS1 levels in cynomolgus monkey, and repeated administration results in sustained inhibition that is reversible after drug discontinuation[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
