Definitions

  • the present invention relates to novel substituted p-phenyl carbamates, to pharmaceutical compositions comprising these compounds, to the use of these compounds as pharmaceutical compositions, and to methods of treatment employing these compounds and compositions.
  • the present compounds show inhibition of hormone sensitive lipase. As a result, the compounds are useful for the treatment and/or prevention of diseases and disorders related to hormone sensitive lipase.
  • the overall energy homeostasis of a mammalian system requires a high degree of regulation to ensure the availability of the appropriate substrate at the appropriate time.
  • Plasma glucose levels rise during the post-prandial state, to return to pre-prandial levels
  • FFA levels do not fall in response to insulin, as they do in normal individuals, preventing the normal utilization of glucose by skeletal muscle, adipose and liver. Furthermore, there is a negative correlation between insulin sensitivity and plasma FFA levels.
  • HSL Hormone-sensitive lipase
  • HSL catalyses the conversion of triglycerides to glycerol and fatty acids. It is through the regulation of this enzyme that the levels of circulating FFA are modulated. Insulin leads to the inactivation of HSL with a subsequent fall in plasma FFA levels during the post-prandial state, followed by the activation of the enzyme when the insulin concen-
  • HSL hypoxia-associated kinase A
  • AMP-dependent kinase pathways There are compounds like nicotinic acid and its derivatives, that decrease the activation of HSL via these pathways and cause a decrease in lipolysis that leads to a reduction in the FFA levels.
  • These drugs have a beneficial effect in the utilization of glucose and in the normalization of the excess triglyceride synthesis seen in patients with elevated FFA. However, since these pathways are used by other processes in the body, these drugs have severe side effects.
  • HSL inhibitors WO 01/87843, WO 01/17981 , WO 01/66531, WO 01/83497, and WO 01/26664.

  • p-phenyl substituted carbamate compounds that specifically inhibit the lipolytic activity of HSL and which may be expected to decrease plasma FFA levels.
