Aspergillomarasmine A is a natural aminopolycarboxylic acid with potent inhibitory activity against class B metallo-β-lactamases (MBLs). Aspergillomarasmine A inactivates MBLs by removing a catalytic Zn2+ cofactor. Aspergillomarasmine A acts as a selective Zn2+ scavenger, promoting the dissociation of the metal cofactor, thereby indirectly inactivating NDM-1. Aspergillomarasmine A causes the loss of Zn2+ ions from the low-affinity binding site of NDM-1. The action of Aspergillomarasmine A results in the rapid degradation of Zn2+-deficient NDM-1, thereby enhancing its potency as a β-lactam enhancer. The mechanism of Aspergillomarasmine A has broad applicability among different Zn2+ chelators.
