A compound of the general formula: ##STR1## wherein X is a lower alkylene group which may optionally be substituted by a hydroxyl group, or a lower alkenylene group, Y is (1) a lower alkyl group, (2) a cycloalkyl group containing 3 to 8 carbon atoms, (3) a lower alkenyl group, (4) an aryl group, (5) an aralkyl group or (6) a 3- to 8-membered heterocyclic group, or the partial structural formula Y--SO.sub.2 --X--, with X and Y being combined with each other, represents a group of the formula: ##STR2## wherein l is an integer of 0 to 3, and m and n each is an integer of 0 to 6, provided that the sum of m and n is in the range of 2 to 6, and R is a hydrocarbon group which may optionally be substituted or a 3- to 8-membered heterocyclic group, or a pharmaceutically acceptable salt thereof a method of production thereof and use thereof. The compound (I) has antimicrobial and .beta.-lactamase inhibitory activities.
一种通式为:##STR1##的化合物,其中X是一个较低的烷基烃基,可以选择性地被羟基取代,或者是一个较低的烯基烃基,Y是(1)一个较低的烷基基团,(2)含有3到8个碳原子的环烷基基团,(3)一个较低的烯基基团,(4)芳基,(5)芳基烷基或(6)一个3到8环的杂环基团,或者部分结构式Y--SO.sub.2 --X--,其中X和Y组合在一起,代表一个通式为:##STR2##的基团,其中l是0到3的整数,m和n各自是0到6的整数,前提是m和n的总和在2到6的范围内,并且R是一个可以选择性地被取代的碳氢基团或一个3到8环的杂环基团,或其药用可接受的盐的生产方法和用途。化合物(I)具有抗微生物和β-内酰胺酶抑制活性。
