Abstract
L-733,560 and L-743,872 are water-soluble pneumocandins with potent antifungal activity. By beginning with the NCCLS M27-T method and varying test format (microdilution vs macrodilution), time of reading (24 h vs 48 h), and test medium (RPMI 1640 vs Antibiotic Medium 3), we have demonstrated that the MICs for these compounds can be altered significantly: the microdilution format, reading after 24 h and use of Antibiotic Medium 3 all reduced the measured MIC. No cross-resistance was demonstrated with either fluconazole or amphotericin B.
L-733,560和L-743,872是水溶性肺菌素，具有较强的抗真菌活性。从ncls M27-T方法和不同的测试格式(微稀释vs大稀释)、读取时间(24 h vs 48 h)和测试介质(RPMI 1640 vs抗生素培养基3)开始，我们已经证明，这些化合物的MIC可以显著改变:微稀释格式、24小时后读取和抗生素培养基3的使用都降低了测量的MIC。氟康唑和两性霉素B均未出现交叉耐药。
