生物活性

PF-06445974, a promising positron emission tomography (PET) lead, has exquisite potency at PDE4B with an IC50 <1 nM. The IC50 values are 36, 4.7 and 17 nM for PDE4D, PDE4A and PDE4C, respectively. PF-06445974 has good selectivity over PDE4D, excellent brain permeability, and a high level of specific binding in the "cold tracer" study[1].

IC50 & Target[1]

PDE4B

<1 nM (IC50)

PDE4D

36 nM (IC50)

PDE4A

4.7 nM (IC50)

PDE4C

17 nM (IC50)

体外研究
(In Vitro)

PF-06445974 demonstrates minimal off-target activities in broad-spectrum selectivity panels, with only weak µM activities at PDE10 (IC50=2290 nM), PDE5A (IC50=4640 nM) and GABAA (Ki=3850 nM)[1].

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

体内研究
(In Vivo)

PF-06445974 exhibits high central nervous system (CNS) PET MPO score (4.0). PF-06445974 is a promising radiotracer lead for specific binding assessment. Neuropharmacokinetic study in rats (0.1 mg/kg, IV) confirms high brain permeability with a total brain to plasma ratio of 0.76, corresponding to a free brain to plasma ratio of 0.70[1].

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

Animal Model: Twenty-five drug-naive male 129/B6 PDE4D KO mice (25-35 g)[1]
Dosage: 10 µg/kg
Administration: Dosed intravenously at 10 µg/kg in a 5 mL/kg dosing volume

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.
