Description
Muzolimine is a structurally novel, pyrazolone diuretic with a high-ceiling profile.
It is somewhat slower in onset than furosemide, but has a more prolonged effect,
similar to the thiazides. Muzolimine has been shown to be effective in edema of
cardiac, hepatic and renal origin. It also appears to be effective as an antihypertensive
agent.
Originator
Bayer (W. Germany)
Uses
Diuretic; antihypertensive.
Manufacturing Process
41 g of α-methyl-3,4-dichlorobenzylhydrazine, dissolved in absolute ethanol,
were added dropwise to a solution of 31.8 g of β-amino-β-ethoxyacrylic acid
ethyl ester and 1.5 g of p-toluenesulfonic acid in 150 ml of ethanol at room
temperature under nitrogen gas. After stirring for 2 hours and standing
overnight, the reaction solution was concentrated as far as possible on a
rotary evaporator. The residue which remained was dissolved in 2 N sodium
hydroxide solution. Any unconverted starting products or by-products were
extracted with ether. The aqueous phase was then brought to pH 5 with acetic
acid. The oil thereby produced was taken up in methylene chloride and the
organic phase was dried over Na2SO4. After evaporating off the solvent, the
reaction product crystallized out. It was recrystallized from methanol; melting
point 127°C to 129°C; yield 21 g (38.5% of theory).

World Health Organization (WHO)
Reports of neurological adverse effects, including paraesthesiae
and paralyses, associated with prolonged use of high dosages of muzolimine, were
received shortly after its introduction in 1984.
Check Digit Verification of cas no
The CAS Registry Mumber 55294-15-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,2,9 and 4 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 55294-15:
(7*5)+(6*5)+(5*2)+(4*9)+(3*4)+(2*1)+(1*5)=130
130 % 10 = 0
So 55294-15-0 is a valid CAS Registry Number.
