Torasemide Usage And Synthesis
DiureticsDiuretics are drugs mainly acting on the kidneys to increase the excretion of water and electrolytes, and increase urine output. Their potency can be divided into:
1. potent diuretics (loop diuretics): including furosemide, bumetanide, ethacrynic acid.
2. Middle efficiency diuretics include: thiazide diuretics, such as hydrochlorothiazide, bendroflumethiazide and so on.
3. Inefficient diuretics include: retention of potassium diuretics spironolactone, triamterene and carbonic anhydrase inhibitor acetazolamide and the like.
Potent diuretics effect on medullary loop ramus crude segment medulla,they inhibit reabsorption of active chlorine, followed by inhibiting sodium reabsorption, and play a strong diuretic effect.
Torasemide is a potent diuretic, its mechanism of action is similar to furosemide, it has no effect on the proximal tubules, it does not cause an increase in the discharge of potassium. This product increase renal volume and sodium excretion is dose-dependent , it does not affect the calcium and potassium excretion, excretion and metabolism have no association with renal function, large doses have no significant toxicity. Sort diuretic strength by: bumetanide> torasemide> piretanide> furosemide. It is useful in the treatment of acute and chronic renal failure and essential hypertension. Adverse reactions of torasemide are similar to furosemide ,common adverse reactions are headache, dizziness, weakness, nausea, muscle spasms, but it produces lesser extent of potassium loss ,it has no effect on uric acid, blood glucose and lipid .
The above information is edited by the chemicalbook of Tian Ye.
UsesIt is used as a diuretic.
DescriptionTorasemide is a novel loop diuretic launched in 1993 after a 12-year gap from the last diuretic introduction. It is indicated for the treatment of hypertension and edema associated with chronic congestive heart failure, renal disease and hepatic cirrhosis. Torasemide exerts its major diuretic activity on the thick ascending limb of the Henle's loop to promote rapid and marked excretion of water, Na+, Cl-, and to a lesser extent,K+ and Ca2+. Compared with other loop diuretics such as furosemide, torasemide has a stronger antihypertensive action, a higher bioavailability, a longer duration of action that is independent of the renal function, and has no side effects such as paradoxical antidiuresis. The mechanism of its vasodilating effect has been suggested to result from, at least in part, the competitive antagonism of the thromboxane A2 receptor.

DefinitionChEBI: An N-sulfonylurea obtained by formal condensation of [(3-methylphenyl)amino]pyridine-3-sulfonic acid with the free amino group of N-isopropylurea.
Manufacturing ProcessIn a 100 ml three-necked flask equipped with magnetic stirrer, condenser, thermometer and dropping funnel 3-sulfonylchloride-4-chloropyridine (10 g, 1 eq., 46.7 mmoles) was suspended in t-butyl-methyl ether (MTBE) (30 ml) at room temperature. Ammonium hydroxide, 25% solution (13.5 ml, 2.13 eq.) was dropped into the suspension in a rate such that the temperature is allowed to increase to 22°-26°C, this temperature was maintained until all the ammonium hydroxide was added. The suspension was then to cooled to room temperature and was stirred for 1 h. The pH of the suspension was adjusted to 80.1 by the addition of a few drops of ammonium hydroxide, 25% solution. The suspension was filtered and washed with water (2 times 10 ml) and the wet product (8 g) dried at 40°C, under the 1 mm Hg vacuum. 3-Sulfonamide- 4-chloropyridine was isolated in 74.4% yield, 6.7 g.
A mixture of 0.01 moles of 3-sulfonamido-4-chloropyridine, 0.02 mole of 3- methylbenzylamine and 50 ml of dry ethanol was heated to reflux temperature for 9 h. After distillation of the ethanol the residue was taken up in an excess of diluted NaOH and the excess of amine was extracted by means of ether.
The aqueous solution was then decolourized with charcoal and filtered, and the filtrate was neutralized with acetic acid. The precipitated product was separated and purified by crystallization from a mixture of water and acetone.The 3-sulfonamido-4-(3-methylbenzyl)amino-pyridine crystallized in the form of beige coloured cristals having a melting point of 184°-186°C. 0.01 mole of 3-sulfonamido-4-(3-methylbenzyl)amino-pyridine was reacted with 0.015 mole of isopropylisocyanate in the presence of 0.02 mole of triethylamine and of 20 ml of dichloromethane, at room temperature for 20 h. After evaporation under vacuum, the residue was taken up in an excess of diluted Na2CO3, filtered off and acidified by means of acetic acid. After precipitation of the product it was filtered and washed several times with ice cold water. The 3-isopropylcarbamoylsulfonamido-4-(3-methylbenzyl)amino_x0002_pyridine (Torsemide) showing as a white powder, has a melting point of 147°- 149°C.
