Ameliorative effect of umbelliferone in remote organ injury induced by renal ischemia-reperfusion in rats

open access: yes, 2021
We evaluated the ameliorative role of umbelliferone in kidney, heart, and lung damage induced by renal ischemia/reperfusion (I/R) injury in rats. Umbelliferone was given orally to rats 60 min before ischemia.

Fluorescence of some simple umbelliferone derivatives

open access: yes, 1979
The absorption and fluorescence spectra of umbelliferone were studied; it was found that in the excited state the basicity of the α-pyrone part of the molecule increases to such an extent that it exceeds that of the phenolate oxygen of the molecule. This
