    摘要： The invention provides novel antibiotic compounds which are 7.beta.-acylamidoceph-3-em-4-carboxylic acids, and non-toxic derivatives thereof, and 6.beta.-acylamidopenam-3-carboxylic acids, and non-toxic derivatives thereof, characterized in that the acylamido group has the structure ##STR1## where R is a hydrogen atom or an organic group and R.sup.a is a hydrogen atom or an acyl group. The compounds are syn isomers or exist as mixtures containing at least 75% of the syn isomer. These antibiotic compounds possess high antibacterial activity against a range of gram positive and gram negative organisms coupled with particularly high stability to .beta.-lactamases produced by various gram negative organisms. The invention is also concerned with the administration of the compounds.

    摘要： The invention provides novel antibiotic compounds which are 6.beta.-acylamidopenam-3-carboxylic acids and non-toxic derivatives thereof, characterized in that the acylamido group has the structure ##EQU1## WHERE R is a hydrogen atom or an organic group and R.sup.a is a hydrogen atom or an acyl group. The compounds are syn isomers or exist as mixtures containing at least 75% of the syn isomer. These antibiotic compounds possess high antibacterial activity against a range of gram positive and gram negative organisms coupled with particularly high stability to .beta.-lactamases produced by various gram negative organisms. The invention is also concerned with the administration of the compounds.

    摘要翻译： 本发明提供了6β-酰基氨基青蒿素-3-羧酸及其无毒衍生物的新型抗生素化合物，其特征在于酰氨基具有结构R。 C 。 CONH PARALLEL NOROR R是氢原子或有机基团，R a是氢原子或酰基。 这些化合物是顺式异构体，或作为含有至少75％的顺式异构体的混合物存在。 这些抗生素化合物对革兰氏阳性和革兰氏阴性生物体的一系列革兰氏阴性菌具有很高的抗菌活性，与各种革兰氏阴性生物产生的β-内酰胺酶具有特别高的稳定性。 本发明还涉及化合物的给药。

    摘要： The invention provides novel antibiotic cefuroxime esters of the formula ##STR1## (wherein R.sup.1 is a primary or secondary alkyl group containing 1 to 4 carbon atoms and R.sup.2 is a primary or secondary alkyl group containing 1 to 6 carbon atoms provided that at least one of the groups R.sup.1 and R.sup.2 is methyl). These compounds are useful as orally administrable broad spectrum antibiotics.
