PF-06446846 is an orally active proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitor. PF-06446846 directly and selectively inhibits translation of PCSK9 by stalling the 80S ribosome in the proximity of codon region.

The free form of the compound is prone to instability, it is advisable to consider the stable salt form (PF-06446846 hydrochloride) that retains the same biological activity.

Description

PF-06446846 is an orally active proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitor. PF-06446846 directly and selectively inhibits translation of PCSK9 by stalling the 80S ribosome in the proximity of codon region[1].

In Vitro

PF-06446846 inhibits the secretion of PCSK9 by Huh7 cells with an IC50 of 0.3 μM[1]. PF-06446846 inhibits PCSK9(1–35)-luciferase expression with an IC50 of 2 μM[1]. PF-06446846 (Compound 7f) shows rat bone marrow and human CD34+ toxicity[2].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Cell Cytotoxicity Assay[2]

Cell Line: Rat bone marrow lineage (−) cell and CD34+ cell
Concentration: 0-20 µM
Incubation Time: 72 h
Result: Showed cytotoxicity with IC50 values of 2.9 µM and 2.7 µM against rat Lin(−) and human CD34+, respectively.
In Vivo

PF-06446846 reduces circulating PCSK9 and total plasma cholesterol levels in vivo without obvious toxicity[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: Male Sprague-Dawley (Crl:CD [SD] rats, five per group; 6–8 wk old at initiation of dosing)[1]
Dosage: 5, 15, and 50 mg/kg
Administration: Oral administration, daily, 14 days
Result: Reduced plasma PCSK9, total plasma cholesterol, and LDL-C (low-density lipoprotein cholesterol) in a dose-dependent manner without obvious toxicity.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
