KPC-2-IN-1
KPC-2-IN-1, boronic acid derivative, is a potent KPC-2 inhibitor with Ki of 0.032 μM. KPC-2-IN-1 enhances the activity of cefotaxime in KPC-2 expressing E. coli. KPC-2-IN-1 exhibits well tolerated in human HEK-293 cells, which can be used for the study of E. coli resistance to β-lactam antibiotics.

Biological Activity
Ki: 0.032 μM (KPC-2)[1].
KPC-2-IN-1 (compound 2e) (50 μg/mL; 16 h) enhances the activity of CTX or MEM in KPC-2 expressing E. coli and (5 μg/mL; 16 h) also shows good combination activity of increasing CTX or MEM susceptibility to E. coli NCTC 10418[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
-
Cell Line:E. coli BL21 DE3 (KPC-2 producing) and NCTC 10418
-
Concentration:5, 50 μg/mL (combine with cefotaxime (CTX) or meropenem (MEM)).
-
Incubation Time:16 h
-
Result:Decreased the MIC of CTX (16 μg/mL) as well as MEM (>64 μg/mL) to ≤ 0.03 or ≤0.06 μg/mL (~512 to >1000-fold increase in susceptibility) againsted E. coli BL21 DE3 and NCTC 10418.
