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.

We previously observed that nonylphenol (NP) exposure during development resulted in increases in body weight and hyperadrenalism in adult male offspring. The mechanism of hyperadrenalism includes the primary activation of the adrenal gland and the conversion of inactive glucocorticoids to
11β-HSD1 has been recognized as a potential therapeutic target for type 2 diabetes. Recent studies have shown that hyperglycemia leads to activation of 11β-HSD1, increasing the intracellular glucocorticoid levels. Excess glucocorticoids may lead to the clinical manifestations of cardiac injury.

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

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

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
