Drugs that could help people to live to 150, based on a compound found in red wine, are being developed by scientists.
The drugs are synthetic versions of resveratrol, found in the skin and seeds of grapes, an organic chemical long thought to have a beneficial effect on health.

Both resveratrol and the artificial versions of it are believed to have an anti-ageing effect, by boosting activity of a protein called SIRT1. However, the human-made versions are much stronger.

Now three of them are in human trials. GSK, the pharmaceutical firm, is testing them on people with particular medical conditions, namely Type II diabetes and psoriasis, a serious skin condition.
