Novel carbapenem compounds, (1R,5S,6S)-2-[1-(1,3-thiazolin-2-yl)azetidin-3-yl]thio-6-[(R)-1-hydroxyethyl]-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.
In the formula,
R ishydrogen; lower alkyl group which is unsubstituted or substituted by hydroxy, lower alkoxy or lower alkoxy-lower alkoxy group; group -COOR¹ (R¹ is hydrogen or lower alkyl group); or group -CONR²R³ (R² and R³ are, independently each other, hydrogen or lower alkyl), and
Y iscarboxy, -COO⊖ or protected carboxy.
These compounds are useful antibiotics for prevention and treatment of bacterial infections.
