Abstract: Nearly all antibiotics are ineffective to the antibiotic-resistant bacteria New Delhi metallo-beta -lactamase-1(NDM-1), one of the most important reasons is that antibiotics can be hydrolyzed by NDM-1 in these bacteria. Up to date, Many compounds, including captopril, are found to possess NDM-1 inhibition activity. Herein we report that some cysteine derivatives or homocysteine derivatives can inhibit the NDM-1 protein, and the lead compound 9 has the inhibition of the NDM-1 protein with IC₅₀ of 1 µM, which is about 8 times potency of captopril.
