Description

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[1]
• uptake of grepafloxacin by THP-1 monocytes[2]
• the uptake of moxifloxacin by THP-1 monocytes[3]

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.[4]
