Topical use of plant extract for skin detoxification

InactiveUS20090306219A1Maintain cellular redox homeostasisReduce hydrogen peroxideBiocideSulfur/selenium/tellurium active ingredientsPeroxideCollard Green
Specific plant extracts are applied topically to upregulate genes which code for proteins to prevent the build-up of and mitigate the activity of various harmful materials within the skin. These upregulated proteins include glutathione transferases, peroxiredoxins, oxidoreductases, glutaredoxins and glutathione syntheses. These proteins produce additional glutathione, glyoxalase I, maintain cellular redox homeostasis, reduce hydrogen peroxide and alkylhydroperoxides, and conjugate glutathione to a wide number of exogenous and endogenous hydrophobic electrophiles. Keratinocytes have been induced to significantly upregulate glutathione and glyoxalase I protein expression. Additionally, keratinocytes pre-treated with diallyl trisulfide have increased viability when exposed to ozone, UV radiation or cigarette smoke extract. The active material can be extracted from plants such as garlic, onions, shallots, leeks, chives, scallions, brussel sprouts, broccoli, cabbage, cauliflower, bok choy, kale, mustard, turnip or radish, may include any compound of the allyl sulfide family, and may be of synthetic origin.

Method of treating glutathione deficient mammals

InactiveUSRE39705E1Stimulate natural productionAntibacterial agentsOrganic active ingredientsRate limitingVitamin C
Glutathione (GSH) is a tripeptide of extreme importance as a catalyst, reductan, and reactant. It can be depleted intra-cellularly either by forming a direct complex with an electrophilic agent (accomplished investigationally by agents such as bromobenzene or diethyl maleate), by way of inhibition of synthesis, or by subjecting cells to oxidant stress. Most cells, except for epithelia cells, do not have a direct transport capacity for intact GSH. Non-epithelial cells must either transport precursor substrates for GSH synthesis or salvage amino acids from circulating GSH for reuse in intracellular resynthesis. Dietary cysteine is a rate limiting substrate for the synthesis of glutathione and also inhibits GSH efflux. Although GSH is synthesized from precursors in virtually all cells, the liver is the main source of plasma GSH. Protection and support of liver function is paramount to elevating GSH levels. The disclosure is also of a unique combination of nutritional supplements including n-acetyl cysteine, vitamin C, 1-glucosamine, n-acetyl d-glucosamine, quercitin, sylimarin, Alpha lipoic acid and high protein, low fat whey that are combined to support various bodily systems involved in glutathione synthesis, reutilization and storage; all intended to elevate glutathione concentration in the mammalian cell.
