Exposing skin to sunlight may help to reduce blood pressure, cut the risk of heart attack and stroke — and even prolong life, a study suggestsResearchers have shown that when our skin is exposed to the sun’s rays, a compound is released in our blood vessels that helps lower blood pressure.

The findings suggest that exposure to sunlight improves health overall, because the benefits of reducing blood pressure far outweigh the risk of developing skin cancer.

The study has been carried out by the University of Edinburgh.

One of the largest contributors to chlorinated solvent waste in medicinal chemistry is chromatography. A set of “drug-like” compounds was employed to compare the relative eluting strengths of greener solvent systems. Disclosed herein is an experimentally-derived solvent selection guide to aid chemists in choosing greener solvents for chromatographic purification, with a particular focus on reducing dichloromethane usage.
