Dimesna reacts with acrolein and other urotoxic metabolites of oxazaphosphorines (cyclophosphamide or ifosfamide) to form stable, non-urotoxic compounds. Mesna does not have any antitumour activity, nor does it appear to interfere with the antitumour activity of antineoplastic drugs. This medication is used to protect the bladder wall from the harmful effects of some cancer-fighting drugs.

How to use

In Vitro:

Dimesna modulates paclitaxel-induced hyperpolymerization of MTP in a dose-dependent manner, and mesna, an in vivo metabolite of Dimesna, protects against time-dependent cisplatin-induced inactivation of MTP. Dimesna -mediated prevention or mitigation of cisplatin-induced nephrotoxicity may involve aminopeptidase N (APN) inhibition by certain Dimesna -derived esna-disulfide heteroconjugates and appears correlated to the presence of a glycinate moiety and/or an anionic group. Two general mechanisms for Dimesna -mediated nephroprotection of cisplatin-induced nephrotoxicity involving the gamma-glutamyl transpeptidase (GGT), APN and cysteine-conjugated-β-lyase (CCBL) nephrotoxigenic pathway are proposed which acting in a concerted and/or synergistic manner, and thereby prevent or mitigate cisplatin-induced renal toxicity. Mesna and its dimer, Dimesna, are coadministered for mitigation of ifosfamide- and cisplatin-induced toxicities, respectively. Dimesna is selectively reduced to mesna in the kidney, producing its protective effects. In vitro screens of uptake and efflux transporters reveal renal organic anion transporters OAT1, OAT3, and OAT4 are responsible for kidney-specific uptake of Dimesna. Uptake of Dimesna by OAT1, OAT3, and OAT4 is determined to be saturable with KM of 636 μM, 390 μM and 590 μM, respectively.

In Vivo:

Tumors of urinary bladder induced by cyclophosphamide (CP) in rats can be significantly reduced by Dimesna administration in a dose-related manner.
