| | nafcillin Usage And Synthesis |
| Originator | Unipen,Wyeth,US,1964 | | Uses | Antibacterial. | | Definition | ChEBI: Nafcillin is a penicillin in which the substituent at position 6 of the penam ring is a (2-ethoxy-1-naphthoyl)amino group. It has a role as an antibacterial drug. It is a penicillin and a penicillin allergen. It is a conjugate acid of a nafcillin(1-). | | Manufacturing Process | A stirred suspension of 12.6 grams 6-aminopenicillanic acid in 130 ml dry
alcohol-free chloroform was treated with 16 ml triethylamine and then with
13.8 grams of a solution of 2-ethoxy-1-naphthoyl chloride in 95 ml
chloroform. After being washed successively with 58 ml each of 1 N and then
0.1 N hydrochloric acid the chloroform solution was extracted with N aqueous
sodium bicarbonate (58 ml + 6 ml). The combined bicarbonate extracts were
washed with 20 ml ether and then evaporated at low temperature and
pressure to give the crude sodium salt of 2-ethoxy-1-naphthylpenicillin [also
called sodium 6-(2-ethoxy-1-naphthamido)penicillinate] as a yellow powder
(20.3 grams). This was dissolved in 20 ml water at 30°C and diluted with 180
ml n-butanol, also at 30°C, with stirring. Slow cooling to 0°C gave colorless
needles of the product. | | Brand name | Nallpen (GlaxoSmithKline). | | Therapeutic Function | Antibacterial |
