Mesna C화학적 특성, 용도, 생산
화학적 성질
White to Off-White Solid
용도
Mesna 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.
World Health Organization (WHO)
Mesna, an antidote used to protect patients treated with
cyclophosphamide or ifosfamide from haemorrhagic vesiculitis, was introduced on
the market in 1984. Shortly afterwards, its use became associated with allergic
reactions, which occurred mainly in patients treated with the oral solution. This led
to the withdrawal of this formulation in Germany, the only country where it was
marketed. An oral liquid dosage form is still registered, but not marketed, in the
Netherlands and products for intravenous injection remain available elsewhere.
일반 설명
Pharmaceutical secondary standards for application in quality control, provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards.
색상 색인 번호
Mesna is used as a mucolytic agent, and as an antidote to chloro-acetyl-aldehyde and acrolein (a bladder toxic metabolite of ifosfamide or cyclophosphamide). It hasbeen reported as a cause of occupational allergic (hand and airborne) dermatitis in nurses
Purification Methods
It can be recrystallised from H2O and does not melt below 250o. It is purified further by converting to the free acid by passing a 2M solution through an ion-exchange (Amberlite IR-120) column in the acid form, evaporating the eluate in a vacuum to give the acid as a viscous oil (readily decomposes) which can be checked by acid and SH titration. It is then dissolved in H2O, carefully neutralised with aqueous NaOH, evaporated and the salt recrystallised from H2O [Schramm J Am Chem Soc 77 6231 1955]. [Beilstein 4 IV 85.]
