(8) Unless defined otherwise, all technical and scientific expressions or terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which embodiments of the invention pertain.
(9) In describing and claiming the embodiments of the present invention, the following terminology will be used in accordance with the definitions set out below which are known in the art.
(10) The singular forms “a,” “an,” and “the” include plural reference unless the context clearly dictates otherwise. Also the term ‘composition’ does not limit the scope of the invention it may include multiple compositions illustrations to establish best mode of the invention.
(11) The term “pharmaceutically/nutraceutically acceptable salt,” as use herein, represents those salts which are, within the scope of sound medical judgment, suitable for use in contact with the tissues of humans and animals without undue toxicity, irritation, allergic response and the like and are commensurate with a reasonable benefit/risk ratio. Particularly the term “pharmaceutically-acceptable salts” refers to the relatively non-toxic, inorganic and organic acid addition salts of compounds, alkali or alkaline earth metal salts, as well as solvates, co-crystals, polymorphs, isomers, enantiomers, congeners and like thereof.
(12) In preferred embodiment, the present invention provides synergistic composition of therapeutically active agents.
(13) Particularly, the invention provides synergistic combination of betaine of thiol histidine and sirtuin activator(s), optionally fatty acid transporter(s) in therapeutically effective amount.
(14) In another preferred embodiment, the invention discloses the synergistic combination of ergothioneine and nicotinamide mononucleotide, optionally acetyl-1-carnitine or pharmaceutically acceptable salts thereof along with pharmaceutically acceptable carriers.
(15) In one embodiment, the invention provides nutritional composition comprising thiol mediated moiety called L-Ergothioneine or L-EGT which act as ROS scavenger/inflammation suppressor.
(16) In the present invention the thiol mediated active moiety ‘Ergothioneine’ can also be referred as L-Ergothioneine; L-EGT; L-(+)-Ergothioneine (ERG); 2-mercaptohistidine trimethylbetaine, 2-Mercapto-L-histidine betaine; S-alpha-carboxy-2,3-dihydro-N,N—N-trimethyl-thioxo-1H-imidazole-4-eth-anaminium hydroxide; Thiasine; Thiazine; Thiolhistidinebetaine; Thioneine. Hereinafter the L-Ergothioneine is referred as ‘EGT’ or L-EGT.
(17) ‘Ergothioneine’ is a naturally occurring amino acid and is a thiourea derivative of histidine, containing a sulfur atom on the imidazole ring. It is having chemical formula C.sub.9H.sub.15N.sub.3O.sub.2S.
(18) ##STR00001##
(19) ‘EGT’ is a thiol-containing antioxidant amino acid at physiological pH. It is widely distributed in both the plant and animal kingdoms. Mammals acquire EGT solely through their diet. Foods such as mushrooms, black beans, red meat and oats are rich in EGT. As human body cannot synthesize the ergothioneine, hence the ergothioneine is only taken from dietary supply.
(20) EGT is acknowledged as a safe and effective antioxidant for preventing lipid oxidation-induced quality changes in food and various diseases associated with oxidative stress. This water-soluble antioxidant has the ability to scavenge hydroxyl and peroxynitrite radicals as well as activated oxygen species, such as singlet oxygen. Ergothioneine is a powerful scavenger of hydroxyl radicals.
(21) Unlike other antioxidants such as glutathione or N-acetyl-L-cysteine (NAC, a precursor of glutathione), EGT is characterized by its slow degradation and resistance to disulfide formation. EGT disulfide formation occurs only at low pH in the presence of Cu.sup.++ or H.sub.2O.sub.2, but not under physiological conditions. Specific organic cation transporter [OCTN1 or ETT] is an integral membrane protein which transports EGT, depending on the concentration of Na and W. Further EGT accumulates in the organelle, where OCTN1 is expressed and protects the cell from damage by ROS generated through inflammation. Ergothioneine is the best known substrate of ETT. The ETT is a protein integrated into the cell membrane. It is noteworthy that transport of ergothioneine by OCTN1 protects cells against oxidative damage and thus reduces the inflammation caused by the secretion of cytokines.
(22) Furthermore L-EGT participates in the production of ATP as part of the electron transport chain and protects the cell/organelles against oxidative damage.
(23) Reactive oxygen species (ROS) and mitochondria play an important role in apoptosis induction under both physiologic and pathologic conditions. Interestingly, mitochondria are both source and target of ROS.
(24) In another embodiment, the redox mechanism of thiol group of L-EGT impacts the cellular function, where during redox signaling, H.sub.2O.sub.2 oxidizes the thiolate anion to sulfenic form (Cys-SOH) causing allosteric changes within the protein that alter its function. The sulfenic form can be reduced to thiolate anions by the disulfide reductases, thioredoxin (Trx) and glutaredoxin (Grx), to return the protein function to its original state.
(25) In another embodiment, the invention provides the active moiety L-EGT improves Nrf2 activity or expression and reduces cell/tissue inflammation by scavenging or reducing production of ROS.
(26) In another embodiment, the synergistic composition comprises therapeutically effective amount of L-EGT or pharmaceutically acceptable salts thereof, wherein L-EGT is present in the range of 1-250 mg, preferably in the range of 1-100 mg.
(27) In the synergistic bioactive compositions L-ergothioneine is present in the range of 0.1% to 70% by wt of total blend or composition, preferably 0.5 to 50% w/w.
(28) In another preferred embodiment, the invention relates to sirtuin activator for repairing DNA damage caused due to oxidative stress or excessive ROS, wherein the sirtuin activator is nicotinamide mononucleotide (NMN) or pharmaceutically acceptable salts thereof, which repairs the damage DNA through suitable mechanism and thus improves the cellular function.
(29) The pharmaceutically acceptable salt of NMN comprises chloride, bromide, sodium, disodium, triflate, acetate and like thereof, preferably the instant composition comprises beta-NMN as SIRT1 activator.
(30) Nicotinamide mononucleotide (“NMN”,“NAMN”) is also referred as beta-Nicotinamide mononucleotide (13-NMN), beta-NMN, beta-nicotinamide ribose monophosphate, Nicotinamide mononucleotide (NMN) or Nicotinamide-1-ium-1-β-D-ribofuranoside 5′-phosphate, nicotinamide ribonucleotide is a nucleotide derived from ribose and nicotinamide. It is having molecular formula C.sub.11H.sub.15N.sub.2O.sub.8P).
(31) ##STR00002##
(32) In certain embodiments, cells treated with a nicotinamide mononucleotide a compound that augments level of intracellular NAD+.
(33) Nuclear DNA damage is regarded as a major culprit in cellular diseases. The unrepaired DNA damage can result in pathological levels of nucleus-to-mitochondria signalling (NM signalling), which may aggravate disease progression. As DNA is constantly assaulted by both endogenous (for example, reactive oxygen species and hydrolysis) and exogenous (such as ultraviolet and ionizing radiation) stresses, cells have evolved several DNA repair pathways to maintain the integrity of DNA. Major DNA repair pathways in the nucleus include direct reversal (DR) of the lesion (usually methylation), base excision repair (BER), mismatch repair (MMR), nucleotide excision repair (NER; comprising global genome NER and transcription-coupled NER), double-strand break repair (DSBR, which includes non-homologous end-joining (NHEJ) and homologous recombination (HR)) and inter-strand crosslink repair (ICLR).
(34) In another embodiment, the nicotinamide mononucleotide (NMN), repair DNA damage via histone deacetylation, through the deacetylation of the two histone acetyltransferases, TIP60 and MOF, which are able to acetylate histone H4. Deacetylation of these two proteins promotes their ubiquitin-dependent degradation affecting DNA double-strand break (DSB) repair either through the repression of repair or affecting the choice of repair mechanism (i.e. homologous recombination or non-homologous end joining).
(35) In another embodiment, the promotion of DNA and protein repair by NMN allows increased cell proliferation, differentiation and viability and thereby improves the cellular health. Moreover the NMN moiety works synergistically such that it controls DNA damage and cell apoptosis in the affected area, such as liver, kidney, uterus, placenta.
(36) In another embodiment, the synergistic composition comprises therapeutically effective amount of NMN or pharmaceutically acceptable salts thereof, wherein NMN is present in the range of 1-500 mg, preferably 1 to 250 mg of total composition, particularly NMN salt is present in the range of 0.1-98%, preferably 0.5-98% w/w of total blend or composition.

(39) Nrf2 is essential transcription factor that regulates detoxifying and antioxidant defense gene expression in liver and kidney cells. Stimulation of Nrf2 signals plays a crucial role in ameliorating pregnancy insults, wherein Nrf2 activation can also be induced by controlling DNA damage or cell apoptosis.
(40) Accordingly, to the invention Nrf2 signalling pathway regulates early embryonic loss, adverse birth outcomes, pregnancy complications such as pre term birth, intrauterine growth restriction (IUGR), early pregnancy loss, neural tube defects (NTD), intra-Uterine Death (IUD), pre-eclampsia (PE).

Stock cells were cultured in MEM supplemented with 10% inactivated Fetal Bovine Serum (FBS), penicillin (100 IU/ml), streptomycin (100 μg/ml) and amphotericin B (5 μg/ml) in an humidified atmosphere of 5% CO2 at 7° C. until confluent. The cells were dissociated with TPVG solution (0.2% trypsin, 0.02% EDTA, 0.05% glucose in PBS). The stock cultures were grown in 25 cm.sup.2 culture flasks and all experiments were carried out in 96 microtitre plates (Tarsons India Pvt. Ltd., Kolkata, India).
(146) iv. Cytotoxicity Studies:
(147) The monolayer cell culture was trypsinized and the cell count was adjusted to 100,000 cells/ml using DMEM-HG containing 10% FBS. To each well of the 96 well microtitre plate, 0.1 ml of the diluted cell suspension was added. After 24 h, when a partial monolayer was formed, the supernatant was flicked off, washed the monolayer once with medium and 100 μl of different test concentrations of test substances were added on to the partial monolayer in microtitre plates. The plates were then incubated at 37° C. for 3 days in 5% CO.sub.2 atmosphere, and microscopic examination was carried out and observations were noted every 24 h interval. After 72 h, the substance solutions in the wells were discarded and 50 μl of MTT in PBS was added to each well. The plates were gently shaken and incubated for 3 h at 37° C. in 5% CO2 atmosphere. The supernatant was removed and 100 μl of propanol was added and the plates were gently shaken to solubilize the formed formazan. The absorbance was measured using a microplate reader at a wavelength of 540 nm. The percentage growth inhibition was calculated using the standard formula and concentration of test substance needed to inhibit cell growth by 50% (CTC.sub.50) values is generated from the dose-response curves for each cell line.

DISCUSSION AND CONCLUSION
(174) A Reverse Transcriptase-PCR experiment was performed by using Nrf2-specific primers. Quantitative RT-PCR analysis revealed that Nrf2 mRNA was increased by test substance treatment (250 μg/ml) compared to the cells control (untreated). There was a notable difference between the mRNA levels of Nrf2 in the cells treated with test substance compared to the cell controls. The presence of test substance produced an increase of Nrf2 mRNA expression in test substance-treated cells. The present composition up regulates the Nrf2 expression by 40 to 70% as compared to control.
