Modulation of mitochondrial respiratory function and ROS production by novel benzopyran analogues [PDF]
A substantial body of evidence indicates that pharmacological activation of mitochondrial ATP-sensitive potassium channels (mKATP) in the heart is protective in conditions associated with ischemia/reperfusion injury.

Computer programs for calculating pKa: a comparative study for 3-(3-(2-nitrophenyl)prop-2-enoyl)-2H-1-benzopyran-2-one [PDF]
Coumarin-based compounds containing a chalcone moiety exhibit antimicrobial activity. These substances are potential drugs and it is important to determine their pKa values. However, they are almost insoluble in water.
