  Methods are described for the treatment and prevention of metabolic disorders or other diseases by administering a pyrone analog or a derivative thereof. Methods are also described for the treatment and prevention of metabolic disorders and other diseases by administering a pyrone analog, or a derivative thereof, in combination with one or more additional agents such as, for example, lipid lowering agents or glucose lowering agents. Methods are described for the modulation of lipid transporter activity to increase the efflux of lipid from a physiological compartment into an external environment. Methods disclosed herein may be used to assess treatment or prevention of a metabolic disorder following administration of a pyrone analog or a derivative thereof.

  Methods and compositions are described that comprise pyrone analogs such as flavonoids and cyclodextrins including quercetin and quercetin derivatives and sulfoalkyl ether cyclodextrins. In some cases the compounds of the invention are administered with a therapeutic agent such as an analgesic. In some cases, treatment with the compositions of the invention can result in the modulation of central nervous system and/or fetal effects of substances. Methods and compositions are described for the modulation of efflux transporter activity to increase the efflux of drugs and other compositions out of a physiological compartment and into an external environment. In particular, the methods and compositions disclosed herein provide for the increase of efflux transporter activity at blood-brain, blood-CSF and placental-maternal barriers to increase the efflux of drugs and other compositions from physiological compartments, including central nervous system and fetal compartments.

  The invention relates to phosphorylated polyphenols, phosphorylated flavonoids, and phosphorylated pyrone analogs. Methods and compositions for the modulation of side effects of substances using such phosphorylated compounds are described. Methods and compositions are described for the modulation of blood-tissue barrier (BTB) transporter activity to increase the efflux of drugs and other compounds out of a physiological compartment and into an external environment. In particular, the methods and compositions disclosed herein provide lowered side effects when phosphorylated pyrone analogs are coadministered with therapeutic agents.
