Xeruborbactam (QPX7728) disodium is a potent, ultra-broad-spectrum boronic acid beta-lactamase inhibitor. Xeruborbactam disodium inhibits key serine and metallo beta-lactamases at a nano molar range[1].
Xeruborbactam disodium is a potent inhibitor of Class D carbapenemases from A. baumannii[1].
Xeruborbactam disodium is minimally affected by the activity of major MDR efflux pumps from P. aeruginosa, representing a significant improvement over the earlier generation boronate beta-lactamase inhibitor (BLI) vaborbactam[1].
The ultra-broad-spectrum beta-lactamase inhibition profile combined with enhancement of the activity of multiple beta-lactam antibiotics with varying sensitivity to the intrinsic resistance mechanisms of efflux and permeability indicate Xeruborbactam disodium is a useful inhibitor for use with multiple beta-lactam antibiotics[1].
