Chemical investigation of the marine algal-derived endophytic fungus Aspergillus alabamensis EN-547 resulted in the isolation of 4-epi-seco-shornephine, a methyl ester, and 4-epi-seco-shornephine, A carboxylic acid, and two new secondary metabolites.

Investigators unravel biological roots of pulmonary hypertension

Working with cells that line the innermost layer of the blood vessels, Johns Hopkins investigators say they have made a leap forward in understanding the underlying biology behind pulmonary hypertension, a dangerous type of high blood pressure in lungs that ultimately leads to right heart failure and death.
