New antibiotics are needed to treat gram-positive bacterial pathogens. is a novel inhibitor of methionyl-tRNA synthetase with selective activity against gram-positive bacteria. The minimum inhibitory concentrations (MICs) against and species range from 0.063 to 0.5 µg/mL. Given orally to mice at 50 mg/kg every 8 hours, shows sustained plasma levels well above these MICs. In the mouse thigh infection model, decreased methicillin-resistant and bacterial loads to the same degree as linezolid. is a promising new antibiotic for development against skin and soft tissue infections.
需要新型抗生素来治疗革兰氏阳性菌病原体。[药物名称]是一种新型甲硫氨酰 - tRNA合成酶抑制剂，对革兰氏阳性菌具有选择性活性。对[具体细菌名称1]和[具体细菌名称2]菌种的最低抑菌浓度（MIC）范围为0.063至0.5μg/mL。以50mg/kg的剂量每8小时给小鼠口服[药物名称]，其血浆水平持续维持在远高于这些MIC的水平。在小鼠大腿感染模型中，[药物名称]将耐甲氧西林的[具体细菌名称1]和[具体细菌名称2]细菌载量降低到与利奈唑胺相同的程度。[药物名称]是一种有前景的新型抗生素，可用于开发治疗皮肤和软组织感染。
