生物活性

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].

体外研究
(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].

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.
体内研究
(In Vivo)

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

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.
