Summary: | The compounds according to the invention correspond to the formula: (I) in which: The COOA group at the 4 position is an acid radical, or an alkaline or alkaline-earth salt, or an amino acid or amine salt, for example triethylamine or ethanolamines, or an easily hydrolyzable or metabolically labile and pharmaceutically acceptable ester radical. X denotes an oxygen atom or a sulfur atom n is zero or 1 R1 and R2 each denote independently hydrogen or a lower alkyl group, preferably a methyl group, or R1 and R2 taken together with the carbon atom to which they are linked form a cyclobutyl or cyclopentyl nucleus. B is the residue of a primary or secondary amine. |
