Description

This application claims priority of provisional application Ser. No. 60/638,918, filed Dec. 23, 2004, the disclosure of which is hereby incorporated by reference.

BACKGROUND OF THE INVENTION

The present invention relates generally to methods and compositions for treating living organisms.
Upon utilization of a nanoscalar particle to achieve a practical purpose, its design and replication defines the field of nanotechnology. Indeed, over the past decade, inventions of biomaterials have focused on synthesis, while purposeful in vivo applications have gone wanting. Developments have resulted from the fabrication of novel architectures that range from Bucky Balls to octahedral DNA. Cytochromes offer some special nanometric advantages that are realized as a result of architecture elucidated within the current invention A diversity of cytochromes present possibilities for multitudes of combinations. For example, linkage of chemical reduction of dioxygen to electrogenic translocation of protons across a membrane occurs through Cytochrome C (Cc) oxidase (A. Namslauer, A. S. Pawate, R. B. Gennis and P. Brzezinski (2003) Redox-coupled proton translocation in biological systems: Proton shuttling in cytochrome c oxidase PNAS 100(26): 15543-15547) and if Cc, for instance, is singled out from all other cytochromes for consideration, over three score evolutionary lines are documented, a diversity that offers many avenues of process.
Cytochromes P450 (P450) are hemoproteins that catalyze monooxygenation of endogenous and xenobiotic hydrophobic substrates. Families of P450 have a broad range of substrates and are responsible for processing metabolic quantities of exogenous compounds by inserting singlet oxygen that renders them soluble for removal. The utilization of oxygen by P450 mediates hydroxylations, epoxidations, dehalogenations, deaminations and dealkylations. The predominance of literature is devoted to P450 monoxygenases (CYP); however, electron reduction must, necessarily, be balanced by coupling reactions with NADPH:Cytochrome P450 reductases (CPR). P450 is understood as an enzyme complex of CYP and CPR.
The present invention generally relates to cytochromes, particularly cytochromes P450. Specifically, the invention is of primary application for electron reduction potential mechanisms that activate the induction, building, and accurate architectural reproduction by over fifty functionally different structures of P450 Each monooxygenase is substrate specific and, coupled with CPR, may be read spectrophotometrically at 450 nm in the presence of carbon monoxide and, for example, nitrobenzoate.
In particular, the present inventor has determined that small quantities of xenobiotics, such as carcinogens and drugs, can be recognized, deactivated and prepared for removal by P450 systems. Although, some substrates are beneficial, others are toxins, mutagens, or carcinogens.
It is in the best interest of humanity to maintain P450 systems at optimal levels to metabolize and remove physiological concentrations of objectionable substances. The majority of xenobiotics, being unavoidable through environmental, gustatory, and pharmaceutical exposures, may be processed at some point of metabolism by P450. On the other hand, inhibitors of P450 are also unavoidable. Upon exposure to the strongest inhibitors, the population is left without the ability to defend adequately against xenobiotics. Until the discoveries of the present invention, a means of re-establishing and/or fortifying P450 to process xenobiotics in living animals had not been made available.

SUMMARY OF THE INVENTION

This invention elucidates a design philosophy that when applied to cytochromes, deals with physiologically important xenobiotics effectively. In certain embodiments, building and increasing quantities of most of the known P450 structures is accomplished in vivo as a consequence of cascading responses to architectural modification, primarily, with the nucleotide, flavin mononucleotide (FMN), within CPR. As these nucleotides are administered into living systems, they move across the surface of reductases as they become integral to the structure and function of entire monooxygenase-reductase complexes, primarily as P450 plus the added FMN (P450:FMN) (or other suitable oxidant).
Thus, a P450:FMN enzyme complex, with more than one FMN molecule in the complex, results in a novel composition of matter (such as in the form of a food supplement, a dietary supplement, a beverage, a topical formulation, or a pill) that assists the body in detoxifying xenobiotics. The direct connection of FMN, for example, to fortify these enzyme complexes, has not been made previously. This invention thus provides methods of detoxification by administering compositions that are selected for accelerating specific activity. These formulations enhance P450 in subcellular nanoarrays. By means of compositions comprised of inducers that are selected for regeneration, the present invention introduces methods of activating repressed nanoscopic structures.
For these reasons, it would be desirable to provide novel methods and compositions for the purpose of fortifying the complexes in humans and other living organisms. It would be particularly desirable if such methods and compositions were able to induce these complexes in specific tissues. The present invention further provides convenient methods resulting in fortification of these complexes for animal and human therapy. It is desirable that the methods and compositions of the present invention promote eradication of undesirable compounds in a manner that enhances the quality of life. It would be further desirable to provide palatable treatments that are nutritious and broadly effective. To that end, preferably, the compositions of an embodiment of the present invention are sweet-tasting, as a rewarding means that encourage daily upkeep of the enzymes complexes.
As a first aspect, the present invention provides isolated P450:FMN compositions of matter wherein there is a plurality of FMN molecules in the enzymatic complex. The methods of isolation, such as from urine or the liver of an animal, are well known to those skilled in the art.
As a second aspect, the present invention provides a method for enhancing P450 family members, numbering over 50, by treatment with their corresponding oxidants. The method comprises administering to an animal in need thereof oxidants that increase the quantity of the complex in that animal.
As a third aspect, the present invention provides compositions for inducing P450:FMN enzyme complexes.
As a fourth aspect, the present invention provides compositions for enhancing anticarcinogenic enzyme complexes in humans. The compositions comprise an effective amount of a nucleotide that increases the amount of the complexes in vivo.
As a fifth aspect, the present invention provides compositions comprising a first compound selected from the group consisting of CPR and oxidants that induce P450:FMN enzyme complexes.
As a sixth aspect, the present invention provides methods for the automatic fortification of P450:FMN enzyme complexes in living systems. The methods include treatment with a compound selected from the group consisting of one or more structural components of the enzyme complexes.
As a seventh aspect, the present invention provides a method for improving the chemical defense of humans and animals using P450:FMN enzyme complexes. The method includes the step of administering to a human or animal in need thereof an effective amount of a composition comprising FMN.
As another specific aspect, the present invention provides methods for dietary supplements to come to the defense of humans against harmful xenobiotics whilst improving nutrition, particularly, in sweeteners.
Compositions are provided that comprise naturally sweet reductants with natural oxidants for increasing the amount of P450:FMN enzyme complexes in an animal.
These and other aspects of the present invention are described further in the detailed description and examples of the invention which follow.

Methods and Compositions
The present invention provides methods for administering substrates that are designed to modify the architecture of P450s and fortify P45:FMN complexes in animals, including humans. These methods typically involve administration of an oxidant component and may, preferably, include administration of an oxidant that is a component of the complex. Oxidants may be formulated with appropriate reductants for balanced therapy and co-induction of monooxygenases and reductases.
Oxidants
Suitable oxidants are compounds that induce NADPH:cytochrome P450 reductase. Any compound capable of inducing such reductases will be useful as the oxidant component in the methods, compositions, and systems of the present invention. Accordingly, reductases, particularly those capable of receiving FMN and nicotinic acids, may be utilized as the oxidant component of the methods, compositions, and systems of the present invention. In addition, a number of other suitable oxidants will be readily determinable by those skilled in the art.
Preferred oxidant compounds exhibit a one-electron reduction potential (E₀) between about −400 mV and about −165 mV inclusive, more preferably between about −396 mV and about −240 mV. Multiple electron reductions are biologically important with P450 and oxygen. Examples of suitable oxidants include, but are not limited to, ferredoxin-NADP+ reductases and NADPH:cytochrome P450 reductase including the reductases listed hereinabove, as well as flavins, nucleotides, nitrobenzoates, nicotinic acids, nitrobenzoic acids, ammonium salts, menadione, amine oxides, formamidines, cytochrome reductases, and slow-release formularies, salts, hydrates, aldehydes, esters, amines, amides, alcohols, derivatives, dietary supplements and other biologically or chemically equivalent derivatives thereof and combinations thereof.
Specific examples of flavins which are useful as oxidants in the methods and compositions of the present invention include, but are not limited to, riboflavin, flavin mononucleotide (FMN), menadione, deazaflavin, lumichrome, lumizine, flavin adenine dinucleotide (FAD), alloxazine, salts, hydrates, derivatives and combinations thereof. Specific examples of ammonium compounds include, but are not limited to ammonium sulfate, ammonium chloride, ammonium hydroxide, urea, amines, and the like. Specific examples of cytochrome reductases include, but are not limited to, cytochrome f, Cc, cytochrome b5, flavocytochrome P450, nitric oxide synthase, and combinations thereof. Specific examples of nicotinic acids include but are not limited to NicoSpan, NiaSpan, niacin, NAD, NADH, NADP, NADPH and combinations thereof. Examples of preferred oxidants, whose selection is based on E₀(values) and beneficial metabolism, include nitrobenzoate (−396 mV), FMN (−313 mV), glycolate (α) (−290 mV), riboflavin (−292 mV), and salts, hydrates and derivatives of any of the above.
Currently preferred oxidants for use in the methods and compositions of the present invention include but are not limited to FMN, NiaSpan, NAD/NADH, menadione, ammonium sulfate, a, and salts, hydrates and derivatives thereof FMN and nicotinic acids are particularly preferred oxidants in the compositions, methods and systems of the present invention, primarily because they are cost effective and generally regarded as safe. Additionally, organ products such as whole liver, dry liver pills, liver oils and liver extracts are excellent sources of undefined cytochromes, oxidants, and reductants. Where organ products are unpalatable or are problematic because of, for instance, cholesterol or gout, it would be advisable to avoid these types of products. Moreover, in the course of processing, proteins and nucleotides may be denatured; thus, organ-derived products may require supplementation with oxidants. FMN is the particularly preferred oxidant.
As noted above, oxidants are employed solely or, they may comprise any one or more of the foregoing oxidants in combination with a reductant or other oxidants. For example, in one preferred embodiment, the oxidant comprises a combination of FMN and fish oil concentrate. In the embodiment of the invention wherein two or more oxidants are combined, they are typically equimolar provisions of the oxidant component of the compositions and methods of the present invention.
Inhibitors
A partial list of inhibitors includes the following common items: foods and beverages, including grapefruit, turmeric (curcuminoids), bergamottin (flavoring in Earl Grey Tea), and well-water (arsenic); drugs, such as, antibiotics (ciprofloxacin, erythromycin, chloramphenicol, and the like), antivirals (ritonavir, etc.); contraceptives (ethynylprogesterone, and the like), antimycotics (ketoconazole, itraconazole, terconazole, miconazole, and the like), chemotherapies (aminoglutethimide, etc.); acid reflux (cimetidine), bioassays (metyrapone, diethyldithiocarbamate), barbiturates and mood drugs (secobarbital, Prozac, Zoloft, Luvox and the like); cosmetics (hydrogen peroxide, dental whitener, bleach, etc.); air pollution from carbon monoxide and other components of smog; insecticides (cyanides, parathion, piperonyl butoxide, etc.); and acyl hydrazine, alkyl hydrazine, aryl hydrazine, allylisopropylacetamide, carbon disulfide, carbon tetrachloride, dichloroacetamides, dihydropyridine, disulfiram, isothiocyanate, mercaptosteroid, phenylimidazole, phenelzine, phenylphenanthridinone, quinolones, syndones, thiourea, tienilic acid, and undecynoic acid.
In a physiological sense, constant exposure to inhibitors renders the general population susceptible to xenobiotics. When P450 is inhibited, it is imperative to resurrect dysfunctional P45:FMN complexes by the compositions and methods of the present invention, if for no other reason than to reduce susceptibility to carcinogens. Inhibitors include compounds that degrade or bind to the heme iron atom or to the prosthetic heme group. Others may be competitive inhibitors of P450, the effects of which may last the half life of a drug.
Application
The oxidants are, by themselves useful in methods of treatment and in methods of fortifying the P40 enzyme complexes. For example, flavins, by themselves, or together with suitable excipients and/or carriers, are useful in the methods of the present invention. Although the oxidant components may be applied in a solid form, it is sometimes advantageous to provide oxidants in liquid form, such as by solubilizing the component in an aqueous or suitable organic solvent or carrier to produce aqueous or organic solutions of the oxidants. The amount of oxidant that is solubilized in the carrier will depend upon the particular oxidant selected and the method of application. The oxidant may be solubilized in the carrier by adding the oxidant to the carrier and allowing the oxidant to dissolve. In some instances, the application of stirring, agitation, or even heat may facilitate the dissolution of the oxidant in the carrier.
For example, suitable formulations are not particularly limited, and include solutions of the oxidant dissolved in a suitable carrier. For example, FMN can be dissolved in a carbonated beverage with or without a reducing sugar such as xylose and/or glucose. The carbon dioxide inhibits premature oxidation of the FMN. FMN in combination with chocolate is another example, such as a formulation comprising 0.2 to 0.5 mg FMN per 30-60 grams of chocolate, preferably dark chocolate. Yet other suitable formulations include the oxidant and one or more reducing sugars, artificial or natural, as discussed above. Still further suitable formulations include emulsions, such as FMN and fish oil, cod liver oil or both. These emulsions can be formulated in a capsule and administered orally. Another suitable formulation is FMN and red wine.
The oxidant can be administered in a carrier to create a formulation having an oxidant concentration in the range between about 0.0001% and about 100% by weight of the composition inclusive, preferably between about 0.01% and about 100% inclusive. For example, because ethanol is an inducer of CYP2E1, a flavin:alcohol beverage ratio of 1:1000 is preferred to match ratios generally found to induce the enzyme complex. An exemplary skin cream comprising 0.1% to 1% α-hydroxy is suitable for topical application when formulated with 0.001% to 0.005% riboflavin.
Compositions of the present invention may also include any of a variety of excipients, which improve or at least do not hinder the beneficial effects of the compositions of the present invention. While the compositions of the present invention may consist essentially of oxidants, compounds may be formulated in suitable excipients. In the embodiment wherein the oxidant is a single composition for use in the methods of the present invention, the composition may include excipients having solubilized, dispersed, supported, or otherwise contained therein, an amount of the oxidant that induces cytochrome P450. A solution containing oxidants may be prepared using the general techniques set forth above.
Compositions containing oxidants in a single solution may include any combination of oxidants selected from those described hereinabove. Preferred oxidants for one-step compositions include, but are not limited to FMN and nicotinic acids. For example, one composition according to the present invention includes menadione and niacin. Another composition according to the present invention includes FMN and cod liver oil. Another composition according to the present invention includes daily 50 mg riboflavin and 5 mg NADP. Another composition according to the present invention includes 1 mg FMN cloaked in carbon dioxide as a stabilizing excipient and to be taken up to 5 times daily.
Compositions of oxidants will typically be administered at a concentration ranging between about 1 mg and about 1000 mg per dose. Preferred combined oxidant compositions include: (1) 5 mg NADH and 25 mg niacin; (2) 5 mg FMN and 50 mg slow-release niacin; and (3) 3 mg FMN and 500 mg fish oil concentrate. Macromolecules such as CPR and CYP pose problems of stability and may require cold storage and inert environments. Formulation with carbonates or bicarbonates prevents oxidation. The compositions of the present invention may also be applied topically in appropriate dermatological or optical formulations.
Compositions according to the present invention may find specifically tailored utilization, including enhanced performance of NADPH:cytochrome P450 reductase; enhanced quantity of NADPH:cytochrome P450 reductase; fortification of P450:FMN enzyme complexes; inducing such complexes after exposure to inhibitors; reduced susceptibility to carcinogens; and for therapy. Compositions may also be formulated at very low concentrations of FMN or in sustained release dosages of niacin for daily enhancement.
The aqueous solutions employed in the systems of the present invention may be formulated in the same manner as described hereinabove for compositions, using the same types of aqueous carriers. Preferably a pharmaceutically acceptable carrier is used. One preferred formulation according to the present invention includes flavin mononucleotide as the oxidant. Another preferred formulation according to the present invention includes niacin as the oxidant. Another preferred system according to the present invention includes flavin mononucleotide and liver extracts as oxidants. Another formulation according to the present invention includes oxidants formulated with reductants such as, reducing sugars; the preferred formulation utilizing treatment with 1 mg to 100 mg NiaSpan, sustained release niacin, as an oxidant formulated with 10 g to 1000 g of a pentose reductant such as xylose.

EXAMPLE 2

The following example illustrates an application of human P450 compositions according to the present invention. Procedures followed previously described methods, e.g., U.S. Pat. No. 6,020,288; M. Markwell, et al., Methods of Enzymology 72: 296-303 (1981); C. A. Mihaliak, et al., Methods in plant biochemistry 19: 261-279 (1993); R. Donaldson, et al., Arch. Biochem. Biophys. 152: 199-215 (1972); and M. Persans, et al., Plant Physiol. 109: 1483-1490 (1995)). The results demonstrate the efficacy of the methods and compositions of the present invention for the enhancement of P450 enzyme complexes.
Methods. CPR substrates have been assayed on various tissues (e.g., U.S. Pat. No. 6,020,288); therefore, response to human CPR (hCPR) was examined under controlled conditions on live index organisms. The direct effects of substrates on hCPR were measured by preparation of microsomes for quantification against CPR and Cc. Controls included equal concentrations of each individual treatment or substrate in surfactant and water. Untreated controls were maintained under identical conditions of culture. Oxidase activity of Cc was inhibited by potassium cyanide. The reaction was initiated by addition of Cc wherein NADPH-dependent reduction of Cc was monitored for increases in absorbance.
Results and Discussion. FMN showed over 4.5 times the induction of components tested. Cytochromes P450 enzyme complexes have defined catalytic electron transfer functions. See, C. von Wachenfeldt, et al., Structures of Eukaryotic Cytochrome P450 Enzymes, P. R. Ortiz de Montellano, ed. (1995) Cytochrome P450: Structure, Mechanism, and Biochemistry (Second Ed.), Plenum Press, New York, pp 183-223 and H. Strobel, et al., NADPH Cytochrome P450 Reductase and Its Structural and Functional Domains, P. R. Ortiz de Montellano, ed. (1995) Cytochrome P450: Structure, Mechanism, and Biochemistry (Second Ed.) Plenum Press, New York, pp 225-244. Combinations of cytochromes P450 are numerous and underscore the potential of the field. Selection of oxidants based on one electron reduction of compounds (see, e.g., Wardman, P. 1989, J Phys. Chem. Ref Data 18(4): 1637-1755) within potentials associated with CPR reductase (see, e.g., Butler, J. et al. 1993 Biochimica et Biophysica Acta 1161: 73) proved successful, test results showing that specific activity may be enhanced by FMN. Oxidants accelerate cytochrome P450 and, FMN, in particular, may fortify its integral structure. In some instances, enhancement of cytochromes other than CPR may be key. For example, Cc may accelerate response where CPR does not, and for those exceptional cases, broad spectrum dosage or specific agents will be the subject of further investigations. Even though the most potent treatment may be nanomolar cytochromes, of the integral components of cytochromes, FMN showed activity at sufficiently low concentrations to be a prime selection for practical, safe and effective therapies. P450 provides widespread applicability of compositions and methods for selection of components which may be utilized to endow animals with a means of resistance to xenobiotic stresses while gaining ever greater health.
