Antibacterial activity is exhibited by novel compounds having the formula ##STR1## or a pharmaceutically acceptable salt thereof. R.sub.3 and R.sub.4 are the same or different and each is hydrogen or alkyl or R.sub.3 and R.sub.4 taken together with the nitrogen atoms to which they are attached form a 1,2-diazacyclobutane, 1,2-diazacyclopentane, 1,2-diazacyclohexane, or 1,2-diazacycloheptane ring. Y.sub.1 and Y.sub.2 are either hydrogen or OR.sub.11 but are not the same. R.sub.11 is hydrogen, alkanoyl of from one to ten carbon atoms, substituted alkanoyl of from two to ten carbon atoms, phenylcarbonyl, (substituted phenyl) carbonyl, heteroarylcarbonyl, phenylalkanoyl, (substituted phenyl) alkanoyl, or heteroarylalkanoyl.
展示抗菌活性的新化合物具有以下公式 ##STR1## 或其药学上可接受的盐。 R.sub.3和R.sub.4相同或不同,每个都是氢或烷基,或者R.sub.3和R.sub.4与它们附着的氮原子一起形成1,2-二氮杂环丁烷,1,2-二氮杂环戊烷,1,2-二氮杂环己烷或1,2-二氮杂环庚烷环。 Y.sub.1和Y.sub.2是氢或OR.sub.11,但不相同。 R.sub.11是氢,从一到十个碳原子的脂肪酰基,从二到十个碳原子的取代脂肪酰基,苯基羰基,(取代苯基)羰基,杂环芳基羰基,苯基烷酰基,(取代苯基)烷酰基或杂环芳基烷酰基。
