There are described pharmaceutical compositions comprising (a) compounds of the formula ##STR1## in which R signifies lower alkoxycarbonyl, lower alkoxy-carbonylamino, the acyl residue of an .alpha.- or .beta.-amino acid or a residue of the general formula Q--X--Y-- (a) wherein Q signifies a 3- to 6-membered ring which optionally contains nitrogen, sulphur and/or oxygen and which is optionally bonded with a fused ring, X signifies a direct bond or a linear "spacer" with up to 6 atoms consisting of carbon, nitrogen, oxygen and/or sulphur, of which up to 2 atoms can be nitrogen atoms and 1 atom can be oxygen or sulphur, and Y represents one of the groups --CO--, --CS--, --CONH-- and (where X contains neither sulphur nor carbonyl as a terminal component) --SO.sub.2 --; and in which R.sup.1 and R.sup.2 together signify a group of the formula ##STR2## wherein A represents hydrogen or a residue which is usable in the 3-position of cephalosporin antibiotics, and in which R.sub.3 represents hydrogen, or their pharmaceutically compatible salts; and (b) a therapeutically effective amount of a .beta.-lactam antibiotic or their pharmaceutically compatible salts; and a pharmaceutically acceptable carrier. The combination is useful in the control or prevention of illnesses caused by .beta.-lactamase forming pathogens.
描述了一种含有以下化合物(a)的制药组合物:##STR1##
其中,R表示较低的烷氧羰基,较低的烷氧羰基氨基,α-或β-氨基酸的酰基残基或Q--X--Y--(a)一般公式的残基,其中Q表示一个3至6个成员的环,该环可选地含有氮,硫和/或氧,并且可选地与融合的环相结合,X表示直接键或由碳,氮,氧和/或硫组成的最多6个原子的线性“间隔物”,其中最多有2个原子可以是氮原子,1个原子可以是氧或硫,而Y代表--CO--,--CS--,--CONH--和(其中X不包含硫或羰基作为末端组分)--SO.sub.2--中的一种基团;并且其中R.sup.1和R.sup.2一起表示以下式子的基团:##STR2##
其中A表示氢或可用于头孢菌素类抗生素的3位,而R.sub.3表示氢,或其药学上相容的盐;以及(b)β-内酰胺抗生素或其药学上相容的盐的治疗有效量;和药学上可接受的载体。该组合物在控制或预防由β-内酰胺酶形成病原体引起的疾病中有用。
