描述 | Methicillin-resistant Staphylococcus aureus (MRSA) is a cause of severe staph infections. PK150 is an analogue of sorafenib that shows 10-fold enhanced anti-MRSA activity. The minimal inhibitory concentration (MIC) of PK150 against MRSA was 0.3-1µM. PK150 also inhibited the methicillin-sensitive strain NCTC 8325 with a MIC of 0.3µM. PK150 at 1.2 and 2.4μM disintegrated S. aureus cells as evidenced by enhanced membrane permeability. The treatment of S. aureus ATCC 29213 bacteria cells with PK150 (2.4μM) for 196h fully eradicated persister cells. The incubation with PK150 at various doses (5, 25, and 50μM) for 80 min inhibited menaquinone-2 synthesis in MenG-overexpressing cells. In a neutropenic mouse thigh model, repeated dosing of PK150 (20mg/kg, p.o.) at 30min, 4h, and 8h after the inoculation of MRSA strain ATCC 33591 resulted in a 10-fold reduction in CFU/g in thighs compared to the vehicle-treated group[1]. |
