In Vitro | In vitro activity: PF-915275 is a novel and selective inhibitor of human 11β-hydroxysteroid dehydrogenase type 1 (11betaHSD1) with Ki of<1 nM and good pharmacokinetics. 11betaHSD1 play a key role in ligand-induced activation of the GR through the production of cortisol. Evidence from genetically modified mice suggests that inhibition of 11betaHSD1 might be a therapeutic approach to treat the metabolic syndrome. 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 Vivo | Adult cynomolgus monkeys were administered either vehicle or various doses of PF-915275 followed by a 10-mg/kg dose of prednisone. Prednisone conversion to prednisolone and the concentrations of PF-915275 were measured by liquid chromatography/tandem mass spectrometry. PF-915275 dose-dependently inhibited 11betaHSD1-mediated conversion of prednisone to prednisolone, with a maximum of 87% inhibition at a 3-mg/kg dose. An exposure-response relationship was demonstrated, with an estimated EC(50) of 391 nM (total) and 17 nM (free). Insulin levels were also reduced in a dose-related manner. These results should enable the development of a biomarker for evaluating target modulation in humans that will aid in identifying 11betaHSD1 inhibitors to treat diabetes and other related metabolic diseases. |
