DuP 105 and DuP 721 are two members of the oxazolidinones, a new class of synthetic antimicrobial agents with activity against gram-positive bacteria. In vitro tests compared the two new drugs with five other antimicrobial agents against 216 gram-positive isolates representing 4 genera and 10 species. DuP 721 MICs for 50% of the strains tested (MIC50s) ranged from 2.0 to 8.0 micrograms/ml, DuP 105 MIC50S ranged from 4.0 to 16 micrograms/ml, and vancomycin MIC50S ranged from 0.25 to 1.0 microgram/ml. Methicillin-resistant and -susceptible staphylococci were susceptible to ciprofloxacin, vancomycin, and DuP 721.
DuP 105和DuP 721是恶唑烷酮类药物中的两个成员,恶唑烷酮类是一类新型的合成抗菌剂,对革兰氏阳性菌具有活性。体外试验将这两种新药与其他五种抗菌剂针对代表4个属和10个种的216株革兰氏阳性分离株进行了比较。DuP 721对50%受试菌株的最低抑菌浓度(MIC50)范围为2.0至8.0微克/毫升,DuP 105的MIC50范围为4.0至16微克/毫升,而万古霉素的MIC50范围为0.25至1.0微克/毫升。耐甲氧西林和对甲氧西林敏感的葡萄球菌对环丙沙星、万古霉素和DuP 721敏感。
