To assess the activities of two glycylcyclines, N,N-dimethylglycylamido (DMG) derivatives of minocycline (MINO) and 6-demethyl-6-deoxytetracycline (DMDOT), 203 gonococcal isolates recovered at six sexually transmitted disease clinics in the western United States were evaluated. Antimicrobial susceptibilities to tetracycline HCl, doxycycline, MINO, DMG-DMDOT, and DMG-MINO were determined by agar dilution tests. DMG-DMDOT and DMG-MINO were more active than tetracycline HCl, doxycycline, or MINO regardless of the presence of Tet M or of chromosomal mutations mediating tetracycline resistance (P < 0.001).
为评估两种甘氨酰环素(米诺环素(MINO)和6-去甲基-6-脱氧四环素(DMDOT)的N,N-二甲基甘氨酰胺(DMG)衍生物)的活性,对在美国西部六家性传播疾病诊所分离出的203株淋球菌进行了评估。通过琼脂稀释试验测定了对盐酸四环素、多西环素、米诺环素、DMG-DMDOT和DMG-MINO的抗菌敏感性。无论是否存在Tet M或介导四环素耐药性的染色体突变,DMG-DMDOT和DMG-MINO都比盐酸四环素、多西环素或米诺环素更具活性(P < 0.001)。
