Researchers from the Peninsula Medical School in Exeter have synthesized a new molecule which releases hydrogen sulfide that promises effective anti-inlammatory drugs.
Researchers from the Peninsula Medical School in Exeter have synthesized a new molecule which releases hydrogen sulfide (H2S) – the gas that gives rotten eggs their characteristic smell and which has recently been found to be produced naturally in the body – and discovered that it could in time lead to a range of new, safer and effective anti-inflammatory drugs for human use.
The study has been published in respected journal Free Radical Biology and Medicine.The new molecule can generate H2S slowly, which is a major breakthrough. Until now, H2S could only be delivered in one go via a gas cylinder or through the use of sulfide salts. Both of which are administered as a large bolus to generate instant H2S and are generally highly toxic, in addition to being foul smelling.
The research team investigated the role of H2S in endotoxic shock, which causes a fatal loss of blood pressure and extensive tissue inflammation. They discovered that when H2S is delivered in a slow and sustained manner, a potent anti-inflammatory effect is produced. Cell signalling molecules that drive inflammation, such as TNFá, IL-1, IL-6 and prostaglandins, were reduced while levels of the body's own anti-inflammatory molecules (i.e. IL-10) were increased. Using H2S donating molecules to control H2S delivery in the body could pave the way for the development of novel approaches to the treatment of inflammatory disorders.
Dr. Matt Whiteman from the Peninsula Medical School, Exeter commented: "We have known for a few years that H2S levels in tissue and blood are markedly elevated during inflammation. It was assumed that this was a bad thing. However, our research is suggesting that H2S could be elevated as part of the body's way to limit inflammation."

Diaper rash is an inflammatory skin condition that occurs in the diaper areas and commonly seen in the babies, especially those who wear diapers constantly.

Dr. Whiteman is highly enthusiastic about the future, adding: "The next step is to secure further funding to expand our work into the clinical setting. We strongly believe that this new and innovative area of research could hold the key to a range of applications for human health. Indeed, we have already shown that the use of H2S and this new H2S donor is beneficial in models of high blood pressure. We are only just starting to unravel the role of H2S has in the body in health and disease."

Mumps - Causes - Symptoms - Diagnosis And Treatment - FAQs
Mumps is a contagious viral infection that typically causes a painful swelling of one or more of the salivary gland. Mumps most commonly occurs in children aged 2-12 years who have not been vaccinated against the disease. However, it can occur at any age. It was a common childhood disease before the development of the mumps vaccine (MMR vaccine).
