| Fenbufen Usage And Synthesis |
| Chemical Properties | White Solid | | Originator | Cinopal,Cyanamid,Italy,1976 | | Uses | Cyclo-oxygenase inhibitor; analgesic; anti-inflammatory | | Uses | muscle relaxant (smooth) | | Manufacturing Process | 135 g of aluminum chloride is dissolved in 500 ml of nitrobenzene, the
solution being held below 10°C by external cooling. A finely ground mixture of
50 g of succinic anhydride and 75 g of biphenyl is added to the stirred
solution, the temperature being held below 10°C. It is then held at room
temperature for four days. After pouring the reaction mixture into a solution
of 150 ml of concentrated hydrochloric acid in 1 liter of ice water, the
nitrobenzene is removed by steam distillation. The solid is collected, dissolved
in 4 liters of 3% hot sodium carbonate solution, clarified, and reprecipitated
by the addition of excess 6N sulfuric acid solution. The crude product is
collected, dried, and recrystallized from ethanol to give the pure subject
compound, MP 185°C to 187°C. | | Therapeutic Function | Antiinflammatory | | General Description | Fenbufen belongs to the class of non-steroidal anti-inflammatory drugs, widely used as an antipyretic and analgesic in medical applications. Its mode of action involves the inhibition of cyclooxygenase enzyme and thereby prevents the synthesis of certain prostaglandins. | | Safety Profile | Poison by ingestion,intraperitoneal, and subcutaneous routes. Human systemiceffects by ingestion: cough, sweating, body temperature.An experimental teratogen. Other experimentalreproductive effects. An anti-inflammatory agent. Whenheated to decomposi |
