D-Captopril
D-Captopril is a NDM-1 inhibitor and a competitive BlaB inhibitor, with an IC50 value of 21.8 µM against NDM-1 and a Ki of 70-100 µM against BlaB. D-Captopril synergistically reduces the minimum inhibitory concentration of Meropenem (HY-13678) against NDM-1-expressing bacteria. D-Captopril binds to BcII via its thiolate sulfur atom and carboxylate group, altering metal ion occupancy and modulating Cd2+ binding affinity. D-Captopril can be used in the research of neonatal meningitis, sepsis and bacterial infections.

NDM-1 21.8 μM (IC50) |
D-Captopril (2 mM; ~5 weeks) binds to BlaB of *Chryseobacterium meningosepticum* by inserting its sulfhydryl group between the two active-site Zn2+ ions of BlaB and displacing the catalytic hydroxyl group. It acts as a competitive inhibitor of BlaB at neutral pH, with a Ki of 70-100 μM[1].
D-Captopril inhibits the enzymatic activity of purified wild-type NDM-1 through interactions with active site residues and stabilized water networks, with an IC50 value of 21.8 μM[2].
D-Captopril (8-32 mg/L) acts synergistically with Meropenem (HY-13678) at the concentration of 32 mg/L, reducing the MIC of Meropenem against E. coli DH5α expressing NDM-1 from 8 mg/L to 4 mg/L, whereas no synergistic effect is observed at the concentration of 8 mg/L[2].
