Many methods such as cefoxitin hodge test, Boronic
acid (BA) inhibition disc test, LN-2-128, RoP 48-1220 inhibition disc test, Syn2190 inhibition disc test, piperacillin and piperacillin/tazobactam (TZP) inhibition disc test, cloxacillin double disc synergy test, agar gradient test (AGT), isoelectric focussing (IF) method, multiplexed polymerase chain reaction (PCR) and conjugation experiments have been mentioned in studies to demonstrate the presence of pAmpC.4,5
Minimum inhibitory concentration (MIC) against selected [beta]-lactams of ceftazidime, cefotaxime, aztreonam, cefepime, imipenem, meropenem, and ertapenem were performed in micro-dilution broth in concentrations of 0.03-32 [micro]g/mL with and without [beta]-lactamase inhibitors such clavulanic acid (4[micro]g/mL) and phenyl boronic
acid (400 [micro]g/mL) (Sigma Aldrich, Stenheim, Germany).

acid and cloxacillin are well considered as Inhibitors of the Amp C enzyme, incorporation of these substances into disk-based assays, increases the probability of detection and help reaching diagnostic finality3,6.
These inhibitors include boronic
acids for KPC detection, dipicolinic acid or Ethylenediaminetetraacetic acid (EDTA) for MBL, clavulanate (an inhibitor of ESBL), cloxacillin (an inhibitor of AmpC) and avibactam (NXL104) for OXA-48.

acid (BA) derivatives have been considered to be reversible inhibitors of AmpC enzymes.
Compared with the molecular structure of five kinds of organic compounds, EAC, DMO, and TG belong to the same series of organic matter with increasing number of ester groups, while TB and TMP contain three ester groups as in TG, but both contain boronic
acid groups and phosphoric acid groups, respectively.
