wherein
R is hydrogen, (C₁-C₃)alkyl, phenyl, benzyl or a conventional radical forming an ester group which is hydrolyzable under physiological conditions;
X is F, Cl, Br, I, (C₁-C₃)alkyl, CF₃, benzyl, (C₁-C₃)alkoxy, (C₂-C₄)alkanoyloxy or (C₂-C₄)alkoxycarbonyl; and
X¹, X² and X³ are each independently hydrogen, F, Cl, Br, I, (C₁-C₃)alkyl, CF₃, benzyl, (C₁-C₃)alkoxy, (C₂-C₄)alkanoyloxy or (C₂-C₄)alkoxycarbonyl; or
a pharmaceutically acceptable cationic salt thereof when R is hydrogen.
2. A compound of claim 1 wherein R is a radical selected from the group consisting of:
furan-5(1H)-on-1-yl;
isobenzofuran-3(1H)-on-1-yl;
3,4-dihydrofuran-5(1H)-on-1-yl;
-CHR¹OCOR², and
-CHR¹OCOOR²;
wherein
R¹ is hydrogen or methyl; and
R² is (C₁-C₆)alkyl.
3. A compound of claim 1 wherein R is hydrogen, (C₁-C₃)alkyl, phenyl or benzyl.
