Ceftezole (or ceftezol) is a semisynthetic first-generation
cephalosporin
The cephalosporins (sg. ) are a class of β-lactam antibiotics originally derived from the fungus ''Acremonium'', which was previously known as ''Cephalosporium''.
Together with cephamycins, they constitute a subgroup of β-lactam antibiotics ...

Ceftezole binds to and inactivates
penicillin-binding proteins (PBPs) located on the inner membrane of the
bacterial cell wall. PBPs are
enzymes involved in the terminal stages of assembling the bacterial cell wall and in reshaping the cell wall during growth and division. Inactivation of PBPs interferes with the cross-linkage of
peptidoglycan chains necessary for bacterial cell wall strength and rigidity. This results in the weakening of the bacterial cell wall and causes
cell lysis.
Ceftezole is having (1,3,4-thiadiazol-2-ylsulfanyl)methyl and
-(1H-tetrazol-1-yl)acetamido side groups located at positions 3 and 7 respectively. It is a cephalosporin and a member of thiadiazoles.
