Anticancer activity of dinuclear gallium(III) carboxylate complexes

The reaction of 3-methoxyphenylacetic acid, 4-methoxyphenylacetic acid, mesitylthioacetic acid, 2,5-dimethyl-3-furoic acid and 1,4-benzodioxane-6-carboxylic acid with trimethylgallium (1:1) yielded the dimeric complexes [Me2Ga(μ-O2CCH2C6H4-3-OMe)]2 (1), [Me2Ga(μ-O2CCH2C6H4-4-OMe)]2 (2), [Me2Ga(μ-O2CCH2SMes)]2 (3) (Mes = 2,4,6-Me3C6H2), [Me2Ga{μ-O2C(Fur)}]2 (4) (Fur = 2,5-dimethylfuran) and [Me2Ga{μ-O2C(Bdo)}]2 (5) (Bdo = 1,4-benzodioxane)...
