IMP-1700 is an inhibitor of bacterial DNA repair.1 It potentiates the activity of the quinolone antibiotic ciprofloxacin against methicillin-resistant S. aureus (MRSA) with a combination index value of 0.7. IMP-1700 inhibits the ciprofloxacin-induced bacterial SOS response, a process that repairs DNA damage, in a reporter assay in a concentration-dependent manner. It is also active against E. coli, as well as methicillin-resistant and -sensitive S. aureus, when used alone (EC50s = 0.5, 0.21, and 3.8 µM, respectively).

Identification of a potent small-molecule inhibitor of bacterial DNA repair that potentiates quinolone antibiotic activity in methicillin-resistant Staphylococcus aureus
Bioorg Med Chem 2019 Oct 15;27(20):114962.PMID:31307763DOI:PMC6892255
The global emergence of antibiotic resistance is one of the most serious challenges facing modern medicine. There is an urgent need for validation of new drug targets and the development of small molecules with novel mechanisms of action. We therefore sought to inhibit bacterial DNA repair mediated by the AddAB/RecBCD protein complexes as a means to sensitize bacteria to DNA damage caused by the host immune system or quinolone antibiotics. A rational, hypothesis-driven compound optimization identified IMP-1700 as a cell-active, nanomolar potency compound. IMP-1700 sensitized multidrug-resistant Staphylococcus aureus to the fluoroquinolone antibiotic ciprofloxacin, where resistance results from a point mutation in the fluoroquinolone target, DNA gyrase. Cellular reporter assays indicated IMP-1700 inhibited the bacterial SOS-response to DNA damage, and compound-functionalized Sepharose successfully pulled-down the AddAB repair complex. This work provides validation of bacterial DNA repair as a novel therapeutic target and delivers IMP-1700 as a tool molecule and starting point for therapeutic development to address the pressing challenge of antibiotic resistance.
