The Uses of Ceftezole
Ceftezole is a β-lactam, cephem antibiotic. It also exhibits potent α-glucosidase inhibitory activity and antidiabetic effect in streptozotocin-induced mouse.
The Uses of Ceftezole
A direct bandgap semiconductor, it is used in a variety of applications, including radiation detectors, photorefractive gratings, electro-optic modulators, solar cells, and terahertz generation and detection. The band gap varies from approximately 1.4 to 2.2 eV, depending on composition.
Definition
ChEBI: Ceftezole is a first-generation cephalosporin antibiotic having (1,3,4-thiadiazol-2-ylsulfanyl)methyl and [2-(1H-tetrazol-1-yl)acetamido side groups located at positions 3 and 7 respectively. It is a cephalosporin and a member of thiadiazoles.
What are the applications of Application
Ceftezole is a product for proteomics research
Manufacturing Process
To a solution of 1 equivalent (eq.) of 1H-tetrazole-1-acetic acid and 1 eq. of
triethylamine in 20 ml of tetrahydrofuran cooled to -20°C was added 1 eq. of
pivaloyl chloride. After thirty-minute stirring of the mixture 20 ml of a
chloroform solution containing 1 eq. of and 1 eq. of triethylamine was poured
into the solution cooled at -10°C during a period of 30 minutes. The resulting
mixed solution was stirred for 30 minutes at the same temperature, for 1 hour
in an ice-water mixture and for 3 hours at room temperature. Removal of a
solvent from the reaction mixture afforded an oily residue, which was
dissolved into 15 ml of 10% sodium bicarbonate aqueous solution. The
resulting aqueous layer was adjusted to pH 1.0-2.0 with 10% hydrochloric
acid, washed with ether and extracted with ethyl acetate. The extract was
washed with water, dried over sodium sulfate and concentrated under reduced
pressure leaving a residue which was triturated with ethyl acetate to obtain 3-
acetoxymethyl-8-oxo-7-(2-tetrazol-1-acetylamino)-5-thia-1-aza-bicyclo[4.2.0]oct-2-ene-2-carboxylic acid.
A solution of 1 eq. of sodium salt of 3-acetoxymethyl-8-oxo-7-(2-tetrazol-1-
acetylamino)-5-thia-1-aza-bicyclo[4.2.0]oct-2-ene-2-carboxylic acid (it may be
prepared with equivalent of sodium bicarbonate and above named acid) and 1
eq. of [1.3.4]-thiadiazole-2-thiol in 20 ml of phosphate buffer (pH 6.4) was
stirred for 5.5 hours at 60°C. The reaction mixture was adjusted to pH 2.0
with 5% hydrochloric acid and treated with ethyl acetate to form a title
compound - ceftezole.
