Discovery of N,N'‐diarylurea molecules with activity against multidrug‐resistant Staphylococcus aureus
摘要:
The emergence and global spread of methicillin‐resistant Staphylococcus aureus (MRSA) pose a serious threat to public health, underscoring the urgent need for novel antibacterial interventions. Here, we screened 18 newly synthesized N,N’‐diarylurea derivatives to identify compounds with activity against MRSA. Our investigations led to the discovery of a small molecule, SCB‐24, which exhibited promising antimicrobial activity against MRSA USA300. Notably, SCB‐24 demonstrated high activity even in the presence of 10% fetal bovine serum and showed excellent selectivity for bacterial over mammalian cells. SCB‐24 also showed potent activity against various MRSA strains, including those resistant to second‐ and third‐line antibiotics. Importantly, the efficacy of SCB‐24 was inferior to that of vancomycin in MRSA‐infected Galleria mellonella larvae. Overall, our findings suggest that SCB‐24 has great potential as a new therapeutic for multidrug‐resistant S. aureus infections.
