Inhibitors of pyruvate dehydrogenase kinase have been proposed as potential treatment for type 2 diabetes, which is characterized by high blood levels of glucose due to insulin resistance. Suggest a biochemical rationale for this proposal.

Homework Answers

Answer #1

The pyruvate dehydrogenase kinase has been proposed as potential treatment for type 2 diabetes, which is characterized by high blood levels of glucose due to insulin resistance.

The pyruvate dehydrogenase kinase up- and down-regulates the activity of the pyruvate dehydrogenase complex (PDC), which is required to maintain the steady-state concentration of ATP during the feed-fast cycle and efficient utilization of fatty acid and glucose. PDC converts pyruvate, coenzyme A (CoA), and NAD+ into acetyl-CoA, NADH and carbon dioxide.

The case study presented below: A 57?year?old female presented with a 13 year history of diabetes. Due to the failure of oral hypoglycemic agents (OHAs) in controlling her sugar levels, for the last 3 years, she was treated with biphasic insulin aspart 30/70. She was a very frequent ier, a regular swimmer and socially very active, and this led her to have irregular meals. Hence, she often go into frequent hypoglycemia and during the last 6 months the patient’s average...
