Novel carbapenem compounds, (1R,5S,6S)-2-[1-(1,3-thiazolin-2-yl)azetidin-3-yl]thio-6-[(R)-1-hydroxyeth yl]-1-methyl-carbapen-2-em-3 -carboxyic acid derivatives. These carbapenem compounds are represented by the following formula having a beta-coordinated methyl group introduced at the 1-position and a [1-(1,3-thiazolin-2-yl)azetidin-3-yl]thio group introduced at the 2-position. ##STR1## In the formula, R is hydrogen; lower alkyl group which is unsubstituted or substituted by hydroxy, lower alkoxy or lower alkoxy-lower alkoxy group; group --COOR.sup.1 (R.sup.1 is hydrogen or lower alkyl group); or group --CONR.sup.2 R.sup.3 (R.sup.2 and R.sup.3 are, independently each other, hydrogen or lower alkyl), and Y is carboxy, --COO.sup..crclbar. or protected carboxy. These compounds are useful antibiotics for prevention and treatment of bacterial infections.
小说新型碳青霉烯类化合物,(1R,5S,6S)-2-[1-(1,3-噻唑啉-2-基)氮杂丁-3-基]硫-6-[(R)-1-羟乙基]-1-甲基-碳青霉烯-2-烯-3-羧酸衍生物。这些碳青霉烯类化合物由以下公式表示,其中在1位引入了一个β-配位甲基基团,在2位引入了一个[1-(1,3-噻唑啉-2-基)氮杂丁-3-基]硫基团。##STR1## 在此公式中,R为氢;低级烷基基团,未取代或取代羟基、低级烷氧基或低级烷氧基-低级烷氧基基团;基团--COOR.sup.1 (R.sup.1为氢或低级烷基基团);或基团--CONR.sup.2 R.sup.3 (R.sup.2和R.sup.3各自独立地为氢或低级烷基),Y为羧基、--COO.sup.或保护羧基。这些化合物是用于预防和治疗细菌感染的有用抗生素。
