PF-915275 is an orally active, potent and selective 11beta-hydroxysteroid dehydrogenase type 1 (11ß-HSD1, HSD11B1) inhibitor (human 11ß-HSD1 Ki <1 nM; cellular IC50 = 5 nM using human 11ß-HSD1-transfected HEK293) with reduced potency toward non-human species (human/monkey/dog hepatocytes EC50 = 20/100/120 nM; mouse 11ß-HSD1 Ki = 750 nM, rat hepatoma EC50 = 14 μM). PF-915275 (0.1-3-mg/kg via nasogastric intubations) inhibits prednisone-to-prednisolone conversion in cynomolgus monkeys (by 87% with 3 mg/kg) in vivo and reduces plasma insulin increase following prednisone & resumed feeding (4 hrs post PF-915275) among overnight fasted monkeys.

11β-Hydroxysteroid dehydrogenase 1 (11β-HSD1) is distributed mainly in the human liver, with no detectable levels in the intestine or kidney, based on a newly developed proteomic approach. 11β-HSD1 is mostly membrane-bound and retained in the liver microsomal fraction. Interindividual variability

The anti-inflammatory and immunomodulatory effects of macrolides include the ability to decrease mucus secretion and inhibit inflammatory mediators in chronic rhinosinusitis. Nevertheless, their mechanisms of action remain to be determined. Here we have investigated the effects of macrolide antibiotics (clarithromycin

Rising obesity rates worldwide have socio-economic ramifications. While genetics, diet, and lack of exercise are major contributors to obesity, environmental factors may enhance susceptibility through disruption of hormone homeostasis and metabolic processes. The obesogen hypothesis contends that chemical exposure early

Glucocorticoids, through activation of the glucocorticoid receptor (GR), regulate hepatic gluconeogenesis. Elevated hepatic expression and activity of 11beta-hydroxysteroid dehydrogenase type 1 (11betaHSD1) play a key role in ligand-induced activation of the GR through the production of cortisol. Evidence from genetically
Nonylphenol (NP) is an environmental endocrine-disrupting chemical (EDC) detected in human cord blood and milk. NP exposure in developmental periods results in hyperadrenalism and increasing 11β-hydroxysteroid dehydrogenase I (11β-HSD1) activity in an adult rat model. Alleviating 11β-HSD1 activity is therefore
