Neutral water-soluble post-transition-metal chelate complexes of medical interest: Aluminum and gallium tris(3-hydroxy-4-pyronates)

A series of tris(3-hydroxy-4-pyronato)aluminum(III) and -gallium(III) complexes have been prepared with the pyrones pyromeconic acid (Hpa), maltol (Hma), kojic acid (Hka), and chlorokojic acid (Hck). They have been characterized by their IR, UV, 1H and 27Al NMR, and fast atom bombardment (FAB) mass spectra. The complexes of Hma and Hka are water-soluble (2-60 mM) but retain their neutral charge in water according to conductivity measurements. Variable-pH 27Al NMR spectra demonstrate that Al(ma)3 and Al(ka)3 are stable to hydrolysis in pH 4.5-8 solutions while n-octanol/water partition coefficients show that the most water-soluble complexes - Al(ma)3 (60 mM) and Ga(ma)3 (31 mM) - are also the most lipophilic. Preliminary toxicity studies show that Al(ma)3 is extremely neurotoxic.
