Salsalate lowers blood glucose in type 2 diabetes, study suggests

In continuation of my update on Salsate

Joslin scientists report that salsalate, a drug used to treat arthritis, lowers blood glucose and improves glycemic control in type 2 diabetes. These findings, which were published today by the Annals of Internal Medicine, provide additional evidence that salsalate may be an effective drug to treat type 2 diabetes.

Salsalate lowers blood glucose in type 2 diabetes, study suggests

Clues to aspirin's anti-cancer effects revealed.....................

In continuation of my update on aspirin....

One of the world's oldest medicines may hold the secret to a very contemporary problem: preventing cancer. Exactly why salicylate shows such potential as an anti-cancer treatment remains unclear, but a new study in mice offers clues.

Salicylate, found in willow bark, has been a key ingredient in medicine cabinets for thousands of years – ancient Egyptian manuscripts describe it as a treatment for inflammation. In a modified form – aspirin – it remains a successful anti-inflammatory and analgesic. Recently, though, research has revealed a puzzling side-effect of taking aspirin: the drug seems to lower a person's chances of developing some forms of cancer.

Aspirin is rapidly broken down inside the body into salicylate, so to investigate aspirin's unexpected side-effects Grahame Hardie at the University of Dundee, UK, applied salicylate to cultured human cells derived from the kidney. He found that the drug activated AMPK, an enzyme involved in cell growth and metabolism that has been found to play a role in cancer and diabetes.

"This is an ancient herbal remedy which has probably always been part of the human diet," says Hardie. "But despite that we're still finding out how it works."

Co-author Greg Steinberg of McMaster University in Hamilton, Ontario, Canada, then tested high doses of salicylate on various types of mice. He found that those engineered to lack AMPK did not experience the same metabolic effects from salicylate as seen in mice with AMPK.

Salicylate, in a form called salsalate, has also shown promise as a treatment for insulin-resistance and type 2 diabetes. Those effects, however, appear not to be governed by AMPK. When insulin-resistant mice lacking AMPK were given salicylate, they showed the same improvement in blood glucose levels as normal mice.

"That's what makes aspirin so scientifically and clinically interesting," says Chris Paraskeva at the University of Bristol, UK, who was not involved in the work. "It potentially works through a number of different pathways."

Salsalate may be useful for the treatment of patients with type 2 diabetes .....

We know that Salsalate (see structure; source Drugs.com)  is a  non-steroidal anti-inflammatory drug (NSAID) belonging to salicylates. It is used in the treatment of Osteo Arthritis and  Rheumatoid Arthritis. 

Now researchers from Harvard Medical School, lead by Dr. Allison Goldfine, have come up with interesting finding, i.e., Salsalate may be useful for the treatment of patients with type 2 diabetes as well. In a three-month trial of people with type 2 diabetes ,  those who took the drug showed significantly improved blood glucose levels. 

Starting off, the patients all had levels of hemoglobin A1C (a standard measurement that reflects blood sugar levels over several months) in the range of 7.0 to 9.5%. A significant number of those who took salsalate saw this number drop by 0.5%, a result that is in the range of several recently released diabetes therapeutics. Other tests related to glucose levels also showed substantial improvement.  

Overall the drug appeared to be safe and to be tolerated well by patients. The study included 108 individuals, aged from 18 to 75 years, at 17 clinical sites around the United States. Patients were randomly divided into four; three groups were each given differing amounts of salsalate in three daily doses, while the fourth received placebos. All patients continued with their current regimes for managing diabetes.

Though these preliminary findings  suggests  that,   salsalate may provide an effective, safe and inexpensive new avenue for diabetes treatment, however the researchers  want to complete the ongoing  additional studies so that they can further substantiate their claim........
