Abstract MESNA is the sodium salt of 2‐mercaptoethane sulfonate, a thiol‐containing drug. It is an antioxidant used particularly in renal protection. Several studies have proved that MESNA has benecial effects in ischemic acute renal failure where it scavenges reactive oxygen species (ROS), due to the presence of the thiol group. It also reduces the size of urinary bladder cancer. MESNA was proved to be effective in preventing hemorrhagic cystitis induced by high doses of several chemotherapeutic regimens such as cyclophosphamide and ifosfamide. It has been shown that MESNA functions as an uroprotective substance in drug‐induced experimental bladder cancer models. Moreover, recent studies have suggested that it is also effective in reducing intestinal inammation in colitis. Because of the increased level of interest in using MESNA for treating various disorders, a new and sensitive method was needed to understand the pharmacokinetics of this drug. Accordingly, we developed a new method for determining free MESNA in biological samples by using ThioGlo‐3 [3H‐Naphto [2,1‐b] pyran, 9‐acetoxy‐2‐(4‐(2,5‐dihydro‐2, 5‐dioxo‐1H‐pyrrol‐1‐yl) phenyl‐3‐oxo)] as the derivatizing agent. MESNA was detected uorimetrically by reverse‐phase HPLC using acetonitrile:water (75:25) along with acetic acid and phosphoric acid (1 mL/L each) as the mobile phase. The detection limit was 1.64 n m per 20 µL injection volume, with a linearity ( r = 0.999) in the calibration curve extending over a range 2.5–2500 n m . The coefcients of variation for within‐run and between‐run precision were 0.43 and 3.31%, respectively. The relative recoveries in the biological samples were in the range 87 ± 6 to 93 ± 2.4%. The concentrations of MESNA in the biological samples (lungs, liver, kidney and brain) were determined. The highest concentration of MESNA was found in plasma. Of all the tissues, the kidney was found to have the highest concentration while the liver had the lowest concentration. Copyright © 2004 John Wiley & Sons, Ltd.
