Given that β-lactam antibiotic resistance mediated by metallo-β-lactamases (MβLs) seriously threatens human health, we designed and synthesized nineteen hydroxamicacids with benzenesulfonamide, which exhibited broad-spectrum inhibition against four tested MβLs ImiS, L1, VIM-2 and IMP-1 (except 6, 13 and 18 on IMP-1, and 18 on VIM-2), with an IC50 value in the range of 0.6–9.4, 1.3–27.4, 5.4–43.7 and

in the interior that strongly influenced their molecular recognition. Templates/guests with strong hydrogen-bonding groups in the midsection of the molecule benefited most, especially if the hydrophobe of the template could penetrate the amide layer to reach the hydrophobic core of the cross-linked micelles. The location and the orientation of the hydrophilic groups were also important, as they determined
