PF-915275 is a potent and selective inhibitor of human 11β-hydroxysteroid dehydrogenase type 1 (11βHSD1) (Ki ＜ 1 nM) with good preclinical pharmacokinetic properties.IC50 value: ＜ 1 nM (Ki)[2]Target: 11βHSD1in vitro: PF-915275 maintains potency in our cellular assay against human 11βHSD1 (HEK293, EC50 = 5 nM) and is selective against human 11βHSD2 (HEK293, 1.5% inhibition 10 μM). PF-915275 displays only weak affinity for the rodent choline transporter (Ki = 9.6 μM) and the hamster melatonin MT3 receptor (Ki = 9.6 μM) in the Cerep Bioprint screening panel. PF-915275 has good in vitro pharmacokinetic properties. In particular, PF-915275 is categorized as a low clearance compound (liver microsome assays) with high permeability (Caco2 assay). [2]in vivo: As a prelude to in vivo studies with PF-915275, the rat pharmacokinetic properties of this compound were determined. PF-915275 has an excellent pharmacokinetic profile characterized by low clearance, long half-life and good oral bioavailability. [2]

Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months.
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
