Application

R-(+)-DIOA has been used as a potassium/chloride K+-Cl- transport inhibitor to study its effects on:
  • short circuit current (Isc) in rat semicircular canal duct (SCCD) epithelium
  • uptake of grepafloxacin by THP-1 monocytes
  • the uptake of moxifloxacin by THP-1 monocytes

Biochem/physiol Actions

[(dihydroindenyl)oxy]acetic acid (DIOA) acts as a potent inhibitor of potassium/chloride (K+–Cl−) co-transporter. It does not exert its effects on bumetanimide-sensitive [Na+,K+,Cl-]-cotransport system.
