• Beschreibung

  Cephadroxil is an orally administered antibiotic, which is very similar to cephalexin. After oral administration, its peak serum level is slightly lower than that of cephalexin, but it is excreted more slowly. Therefore, it can be used for oral administration at 8- or 12-hourly intervals (Buck and Price, 1977; Pfeffer et al., 1977). Cephadroxil is still available in a number of European countries (for example, Spain, Belgium, Luxembourg, Portugal, and Finland, among others).

• Chemische Eigenschaften

• Definition

  ChEBI: A cephalosporin bearing methyl and (2R)-2-amino-2-(4-hydroxyphenyl)acetamido groups at positions 3 and 7, respectively, of the cephem skeleton.

• Manufacturing Process

  1.8 g of sodium N-(1-methoxycarbonyl-1-propen-2-yl)-D(-)-α-amino-(4- hydroxyphenyl)acetate was suspended in 10 ml of acetone, and one droplet of N-methylmorpholine was added thereto, and the mixture was cooled to -15°C.There was added 0.85 g of ethyl chlorocarbonate thereto, and the mixture was reacted at -13°C to -10°C for 30 minutes, and then the reaction solution was cooled to -20°C.
  On the other hand, 1 g of 7-amino-3-methyl-3-cephem-4-carboxylic acid was suspended in 20 ml of methanol, and 1.4 g of triethylamine was added thereto to be dissolved, and 0.4 ml of acetic acid was further added thereto. This solution was cooled to -20°C and the mixed acid anhydride prepared previously was added thereto. After the mixture was reacted at -20°C for 1 hour, the temperature of the reaction mixture was raised to 0°C over a period of 1 hour, and the mixture was reacted for 3 hours at the same temperature.
  After the reaction, 1 ml of water was added to the reaction mixture, and the mixture was adjusted to a pH of 1.0 with concentrated hydrochloric acid while being cooled, and then stirred for 30 minutes, The insoluble matters were filtered off, and the filtrate was adjusted to a pH of 5.5 with triethylamine. This solution was concentrated under reduced pressure, and the residue was diluted with 20 ml of acetone to precipitate white crystals. The crystals were collected by filtration and washed with ethanol to obtain 1.46 g of white crystals of 7-[D(-)-α-amino-(4-hydroxyphenyl)acetamido]-3-methyl-3- cephem-4-carboxylic acid having a decomposition point of 197°C.
