Abstract
Described is a natural product-containing supplement that enhances intracellular concentration of bioactive molecules through inhibition of MDR efflux pumps. Specifically described are dosage forms for administration to a subject, the dosage forms having at least four ingredients selected from the group consisting of apigenin, cannabidiol, chrysin, harmine, caffeic acid, piperine, nobiletin, Hypericum perforatum extract, bee propolis, oleanolic acid, biochanin, luteolin, vanillin, honokiol, pterostilbene, and withaferin A. Upon administration to a mammalian subject, the dosage forms generally inhibit mis-regulated MDR efflux pumps that are responsible for pushing out good nutrients from the cell—thus increasing intracellular concentration of health-promoting compounds.

Description
DETAILED DESCRIPTION
[0024] Phytonutrients are the “medicinal” component of plants and are commonly a starting point in the drug discovery process. The phytonutrients described herein have generally been extracted (e.g., from raw plant/fungal material) and/or standardized to the respective compounds for assimilation into the dosage form(s). Such processing increases reproducibility and quality, reduces the bulk of the selected phytonutrients and allows for smaller, easier to swallow dosage forms.
[0025] Although the phytonutrients (and other ingredients) are readily commercially available, processes for extracting phytonutrients are known in the art and may be advantageously utilized herein.
[0026] Efflux pumps relevant to this disclosure include ABCG2 (more commonly referred to as Breast Cancer Resistance Protein or “BCRP”), Cytochrome P.sub.4502C8 (“CYP2C8”), MDR-TB, multidrug resistance-associated protein 1 (“MRP1” or “ABCC1”), Multidrug resistance-associated protein 2 (“MRP2”) also called canalicular multispecific organic anion transporter 1 (“cMOAT”) or ATP-binding cassette sub-family C member 2 (“ABCC2”), P-glycoprotein (P-glycoprotein 1 also known as multidrug resistance protein 1, ATP-binding cassette sub-family B member 1 or “P-gp”), and UGT-1A9 (UDP glucuronosyltransferase family 1 member A9).
[0027] Examples of substances that are useful for incorporation in the dosage forms described herein include apigenin, cannabidiol, chrysin, harmine, caffeic acid, piperine, nobiletin, Hypericum perforatum extract, bee propolis, oleanolic acid, biochanin, luteolin, vanillin, honokiol, pterostilbene, and withaferin A. Each such substance is a naturally occurring, albeit purified product (e.g., a flavonoid) that inhibits at least one MDR efflux pump in a subject's cell. Taken together (e.g., administered to a subject who would benefit from such therapy in a non-naturally occurring combination of at least four such substances at dosages and as described herein), the combined substances are believed to act synergistically to inhibit the activity of various MDR efflux pumps in a cell (and at the micromolar level) to reduce ejection of various different beneficial phytonutrients from the treated cell, which joint action greatly enlarges the range of each substance's inherent function, activity, and utility. Such synergistic action reduces ejection of the various bioactive health-promoting compounds from the subject's cells by inhibiting several (e.g., at least four) different MDR efflux pumps as described herein, which pumps would otherwise work together to remove the health-promoting compounds from the cell. Administration of the described dosage forms to a subject thus allows the health-promoting compounds to act beneficially in the cell for a longer period of time, thus treating the subject and/or preventing the occurrence of a malady.
