Cephalosporin C is an antibiotic of the cephalosporin class. It was isolated from a fungus of the genus Acremonium and first characterized in 1961. [ 1 ] Although not a very active antibiotic itself, synthetic analogs of cephalosporin C, such as cefalotin , became some of the first marketed cephalosporin antibiotic drugs.
Structure of the classical cephalosporins. The cephalosporins (sg. / ˌ s ɛ f ə l ə ˈ s p ɔːr ɪ n, ˌ k ɛ-,-l oʊ-/ [1] [2]) are a class of β-lactam antibiotics originally derived from the fungus Acremonium, which was previously known as Cephalosporium. [3] Together with cephamycins, they constitute a subgroup of β-lactam antibiotics ...
The core itself can also be referred to as 7-aminocephalosporanic acid which can be derived by hydrolysis from the natural compound cephalosporin C. Chemical compounds containing this core are relatively stable to acid hydrolysis and tolerance to β-lactamases. Cephalosporin C contains a side-chain which is derived from D-aminoadipic acid.
β-Lactam antibiotics are indicated for the prevention and treatment of bacterial infections caused by susceptible organisms. At first, β-lactam antibiotics were mainly active only against gram-positive bacteria, yet the recent development of broad-spectrum β-lactam antibiotics active against various gram-negative organisms has increased their usefulness.

The enzyme cephalosporin-C deacetylase (EC 3.1.1.41) catalyzes the reaction cephalosporin C + H 2 O ⇌ {\displaystyle \rightleftharpoons } deacetylcephalosporin C + acetate This enzyme belongs to the family of hydrolases , specifically those acting on carboxylic ester bonds.

This is a list of common β-lactam antibiotics—both administered drugs and those not in clinical use—organized by structural class. Antibiotics are listed alphabetically within their class or subclass by their nonproprietary ...
Guy Geoffrey Frederick Newton (1919–1969) was a British rower and biochemist. He was the co-discoverer of cephalosporin C.. Newton was born in St. Ives, Cambridgeshire, the son of Bernard Newton a gentleman farmer of Fairfield Bury, St Ives and his wife Antoinette Gerard.
