Induction of cytochrome P450 1a1 by the food flavoring agent, maltol.

Anwar Anwar-Mohamed et al.

Toxicology in vitro : an international journal published in association with BIBRA, 21(4), 685-690 (2007-02-24)

Maltol is used extensively as a flavor-enhancing agent, food preservative, antioxidant, and also in cosmetic and pharmaceutical formulations. However, a number of studies have shown that maltol may induce carcinogenicity and toxicity but the mechanisms involved remain unknown. Therefore, we

Biospeciation of various antidiabetic V(IV)O compounds in serum.

Tamás Jakusch et al.

Dalton transactions (Cambridge, England : 2003), (13)(13), 2428-2437 (2009-03-18)

The interactions of various insulin mimetic oxovanadium(IV) compounds with serum proteins were studied in model systems and in ex vivo samples. For the modeling study, an earlier in situ method was extended and applied to the formation of ternary complexes

Maltol-derived ruthenium-cymene complexes with tumor inhibiting properties: the impact of ligand-metal bond stability on anticancer activity in vitro.

Wolfgang Kandioller et al.

Chemistry (Weinheim an der Bergstrasse, Germany), 15(45), 12283-12291 (2009-10-13)

Organometallic ruthenium-arene compounds bearing a maltol ligand have been shown to be nearly inactive in in vitro anticancer assays, presumably due to the formation of dimeric Ru(II) species in aqueous solutions. In an attempt to stabilize such complexes, [Ru(eta(6)-p-cymene)(XY)Cl] (XY=pyrones
