| Bioactivity | TST1N-224 is a potent response regulator VraRC inhibitor. TST1N-224 can disrupt VraRC-DNA complex formation (IC50=60.2 μM). TST1N-224 exhibits interference with VraRC binding to its cognate DNA through a fast-on-fast-off binding mechanism (KD=23.4 μM). TST1N-224 predominantly interacts with the α9- and α10-helixes of the DNA-binding domain of VraR. TST1N-224 inhibits the growths of S. aureus (SA; MIC>126 μM), Methicillin-resistant S. aureus (MRSA; MIC>126 μM), and Vancomycin-intermediate S. aureus (VISA; MIC=63 μM). TST1N-224, an antimicrobial agent, evidently enhances the susceptibility of VISA to both Vancomycin (HY-B0671) and Methicillin (HY-B0974)[1]. |
