Claziprotamidum
Based on 1 Customer Validation
Claziprotamidum (Claziprotamide; BBP-671) is a panthothenate kinase (PANK) activator with oral activity and blood-brain barrier permeability. Claziprotamidum binds to and activates all PANK isoforms, with the highest affinity for PANK3 (KD = 97 pM; IC50 = 1.39 nM). Claziprotamidum increases the intracellular biosynthesis of Coenzyme A (HY-128851) and restores mitochondrial function. Claziprotamidum can be used in the research of pantothenate kinase-associated neurodegeneration and propionic acidemia.

Claziprotamidum (10 μM; 24 h) increases total CoA levels by 244% in C3A human hepatocyte-like cells[1].
Claziprotamide (BBP-671) acts as an allosteric activator of recombinant PANK1β, PANK2, and PANK3 proteins by reducing their sensitivity to feedback inhibition by acetyl-CoA[2].
Claziprotamidum potently modulates the activity of recombinant human PANK1β, PANK2, and PANK3 proteins, with Ki values of 102 ± 21.4 nM, 2.02 ± 0.52 nM, and 1.39 ± 0.33 nM, respectively[3].
Claziprotamidum binds tightly to recombinant human PANK3 protein with a K0 of 97 ± 2 pM and a residence time of 21.4 minutes[3].
Claziprotamidum (2-7.5 μM) renders recombinant human PANK1β, PANK2, or PANK3 proteins, respectively, highly resistant to inhibition by propionyl-CoA[3].
Claziprotamidum (0.1-90 μM; 24 h) increases total intracellular CoA levels in human liver-derived C3A cells, with maximum elevation at 10 μM[3].

Claziprotamidum (0.1-10 mg/kg; p.o.; single administration) dose-dependently increases total CoA levels in the liver and forebrain of healthy C57BL/6J mice. At a single dose of 10 mg/kg, hepatic CoA levels increase by approximately 110%, and forebrain CoA levels increase by approximately 60%[2].
Claziprotamidum (0.1-30 mg/kg; p.o.; once daily; for 7 consecutive days) dose-dependently increases the drug concentrations in plasma, liver and forebrain of healthy C57BL/6J mice[2].
Claziprotamidum (10 mg/kg; p.o.; once daily; for 5 consecutive days) can cross the blood-brain barrier, increase the total CoA level in brain tissue, and also elevate the total CoA level in liver in healthy Sprague-Dawley rats treated with intracisternal catheterization[2].
Claziprotamidum (1 mg/kg; p.o.; once daily; for 3 consecutive days) transiently increases whole-blood acetyl-CoA levels in healthy C57BL/6J mice, with a peak reached at 4 h after the final administration[2].
Claziprotamidum (3 mg/kg/day; oral administration; via feed; once daily; for 5 consecutive days) doubles the whole-blood acetyl-CoA levels in healthy C57BL/6J mice[2].
Claziprotamidum (10 mg/kg per day; mixed into feed; ad libitum access; for 30 consecutive days) restores total brain CoA levels, increases body weight and improves motor function in Pank1fl/fl,Pank2fl/fl SynCre+ PKAN mice, but produces no statistically significant improvement in their survival rate[2].
Claziprotamidum (22.5 ppm; oral administration; continuous dosing) restores the survival rate of PA mice to 100%, normalizes hepatic CoA metabolite levels, reduces the levels of hallmark PA biomarkers in plasma and urine, and restores mitochondrial TCA cycle function[3].
Claziprotamidum (1 mg/kg; p.o.; single administration) increases the total hepatic CoA concentration in healthy C57BL/6J mice, with the peak observed at 4 h, and the elevated level persists for up to 24 h[3].
Claziprotamidum (11.25-45 ppm; oral administration; continuous dosing; 4 weeks) produces the maximal increase in total hepatic CoA concentration in healthy C57BL/6J mice at the dose of 22.5 ppm, with no additional benefit observed at the higher dose of 45 ppm[3].
Claziprotamidum (22.5 ppm; oral administration; continuous dosing) restores the survival rate of PA mice to 100%, normalizes hepatic CoA metabolite levels, reduces the levels of hallmark PA biomarkers in plasma and urine, and restores mitochondrial TCA cycle function[3].
