TECHNICAL FIELD
This invention relates to inhibiting 11 βHSD1.
BACKGROUND
Diabetes is generally characterized by relatively high levels of plasma glucose
(hyperglycemia) in the fasting state. Patients having type 2 diabetes (non-insulin
dependent diabetes mellitus (NIDDM)) produce insulin (and even exhibit
hyperinsulinemia), whilst demonstrating hyperglycemia.
Type 2 diabetics can often develop insulin resistance, in which the effect of
insulin in stimulating glucose and lipid metabolism is diminished. Further, patients
having insulin resistance, but have not developed type 2 diabetes, are also at risk of
developing Syndrome X (metabolic syndrome). Syndrome X is characterized by insulin
resistance, along with obesity (e.g., abdominal obesity), hyperinsulinemia, high blood
pressure, relatively low HDL and relatively high VLDL.
Glucocorticoids (e.g., cortisol in humans, corticosterone in rodents) are counter
regulatory hormones that oppose the action of insulin. It is established that
glucocorticoid activity is controlled at the tissue level by intracellular interconversion of
active cortisol and inactive cortisone by the 11-beta hydroxysteroid dehydrogenases,
11βHSD1, which activates cortisone and 11βHSD2, which inactivates cortisol. Excess
levels of glucocorticoids (e.g., cortisol) can cause metabolic complications. For example,
excess cortisol is associated with disorders including NIDDM, obesity, dyslipidemia,
insulin resistance, and hypertension.
It is believed that inhibition of 1lβHSDl can reduce the effects of excessive
amounts of 11 P-hydroxysteroids, e.g., cortisol, and therefore can be useful for the
treatment and control of diseases mediated by abnormally high levels of cortiso] and
other 1 l(3-hydroxysteroids, e.g., NIDDM, obesity, dyslipidemia, and hypertension.

subject to microwave irradiation at 160°C for 30 minutes. The reaction mixture was partitioned
between EtOAc and water, organic layer washed with brine and dried over Na2SO4 The crude
product obtained by solvent evaporation was purified via flash column chromatography. 4-(3-
