Priority Claim:
[0001] This application claims priority from the provisional application numbered 202241002521 filed with Indian Patent Office, Chennai on 17th July 2022 entitled “A probiotic formulation for improving oral health and for prophylaxis of cancer”, the entirety of which is expressly incorporated herein by reference.
Preamble to the description
[0002] The following specification describes the invention and the manner in which it is to be performed:
Description of the invention
Technical field of the invention
[0003] The present invention relates to a formulation of probiotic solution as mouth wash for improving oral health, gut health and as prophylaxis for oral cancer. More particularly, the invention relates to a unique mouth wash formulation of probiotic solution comprising beneficial bacteria to optimize the oral health, gut health and to inhibit carcinogenesis.
Background of the invention
[0004] Cancer, being a second main cause of the death in the world is associated with role of pathogens. Oral cancer also known as mouth cancer refers to cancer of the lining of the lips, mouth, or upper throat. In the mouth, it most commonly starts as a painless white patch, that thickens, develops red patches, an ulcer, and continues to grow. Among oral cancers, oral squamous cell carcinoma (OSCC) is the most prevalent and most commonly studied, and it is the most common malignancy of the head and neck worldwide.
[0005] Oral cancer is a multifactorial disease and is caused by the host genetics and various environmental factors. In addition, the consumption of tobacco, alcohol betel quid chewing, smoking cigarettes, cigars, and pipe and infections with human papillomavirus (HPV) are the known risk factors. However, it also be a possible etiology that could be attributed to microbes in around 15% of oral cancer patients without any known risk factors.
[0006] Oral cancer belongs to a larger group of cancers called head and neck cancers. Most cancers develop in the squamous cells found in mouth, tongue, and lips.
[0007] About 30 trillion bacterial cells are living in or on every human i.e., is around one bacterium for each cell in the human body. These microorganisms are on the whole known as the microbiome. The increased interest in the role that the human microbiome plays in human health, many studies have linked changes in microbial communities to systemic conditions such as allergies, diabetes, inflammatory bowel disease, and atherosclerosis. Among the systemic conditions influenced by the microbiome, cancer has not been an exception.
[0008] It is observed that members of the human microbiome are highly associated with a wide variety of cancer types. The presence of oral microbiome is associated with risk of distant multiple cancers such as gastrointestinal-esophageal cancer, pancreatic cancer, hepatic cancer, colorectal cancer, gastric cancer, apart from breast cancer and lung cancer. Some specific species have been identified that correlate strongly with oral cancer, such as Streptococcus sp., Peptostreptococcus sp., Prevotella sp., Fusobacterium sp., Porphyromonas gingivalis, and Capnocytophaga gingivalis. It is observed that the oral periopathogens namely Fusobacterium nucleatum and Porphyromonas gingivalis play an important role in the development of colorectal and pancreatic cancer. [0009] Similarly, Tannerella forsythia is associated with higher risk of esophageal adenocarcinoma and depletion of Neisseria and Streptococcus pneumoniae is associated with lower risk of esophageal adenocarcinoma. The abundance of P. gingivalis is associated with higher risk of esophageal squamous cell carcinoma.
[0010] The microbiome may influence the evolution of the disease by directly interacting with the human body and significantly altering the response and toxicity to various forms of cancer therapy. Some studies have shown an association of certain phylogenetic groups with the immunotherapy treatment outcomes of certain tumors. However, in contrast, it has also been a resurgence in interest on the potential use of bacteria to cure cancer.
[0011] There are different mechanisms explained regarding the role of microbiota in the pathogenesis of cancer. Firstly, bacterial stimulation of chronic inflammation and the inflammatory mediators produced in this process facilitate cell proliferation, mutagenesis, oncogene activation, and angiogenesis. The second mechanism attributed to bacteria that influence the pathogenesis of cancers by affecting cell proliferation is the activation of NF-KB and inhibition of cellular apoptosis. Thirdly, bacteria produce certain substances that act in a carcinogenic manner.
[0012] There is a wide inter-individual diversity in microbial colonization in the oral cavity. This micro -environmental variability connected to the oral microbial flora is likely to modify tumor cell genotype and phenotype. This leads to heterogeneity in the tumor cells.
[0013] The oral cavity and gut are anatomically continuous regions connected through the gastrointestinal (GI) tract. Moreover, both sites are also chemically connected, since saliva and digested food pass through the GI tract. Studies in animals and human have indicated that oral bacteria can translocate to the gut and change its microbiota and possibly immune defense.
[0014] Probiotics are made of good live bacteria that naturally live in the human body. Probiotics maintain a healthy balance in the human body by supporting the immune function and controlling inflammation. In addition, probiotics also help the body to digest food, enhance vitamin production, combat bad bacteria and support the cells that line the gut to prevent bad bacteria from entering blood.
[0015] The existing probiotics may reduce the negative bacteria but may harm the positive bacteria in the oral cavity and are detrimental to oral health. Some studies and extensive data have suggested a link between excessive use of mouthwash especially alcohol based, and oral cancer.
[0016] The Patent Application CN103798392B entitled “The probiotic food composition and food of alleviating botleneck throat inflammation effect” discloses a kind of probiotic food composition and the food with alleviation bottleneck throat inflammation effect. Probiotic food composition of the present invention can be added in various healthy food and health food such as acidified milk, milk sheet etc., can be used for effectively alleviating bottleneck throat inflammation particularly chronic pharyngitis.
[0017] The Patent Application US2016000841A1 entitled “Compositions and methods for promoting growth of beneficial microbes to treat or prevent disease or prolong life ” discloses an inoculation of ATM-deficient mice with probiotic microorganisms, such as L. johnsonii, changed immune parameters, decreased a marker of DNA damage and increased the lifespan of the mice. The compositions and methods described herein are useful for the treatment and prevention of Ataxia telangiectasia and other cancer-prone diseases, such as p53 deficiency -associated cancers. The compositions and methods of the present invention are also useful for treating and preventing radiation-induced toxicity to normal tissue in a subject being exposed to radiation. The compositions and methods of the invention can increase lifespan in a simple, non-invasive manner.
[0018] The Patent Application US8187590B2 entitled “Probiotic, lactic acidproducing bacteria and uses thereof discloses utilization of species or strains of lactic acid-producing bacteria, preferably strains of Bacillus coagulans, for the control of gastrointestinal tract pathogens, including antibiotic -resistant gastrointestinal tract pathogens, and their associated diseases by both a reduction in the rate of colonization and the severity of the deleterious physiological effects of the colonization of the antibiotic-resistant pathogen. In addition, the invention relates to the utilization of therapeutic compounds comprised of lactic acidproducing bacteria and anti-microbial agents such as antibiotics, anti-fungal compounds, anti-yeast compounds, or anti-viral compounds. The invention also discloses methodologies for: (i) the selective breeding and isolation of probiotic, lactic acid-producing bacterial strains which possess resistance or markedly decreased sensitivity to anti-microbial agents (e.g., antibiotics, anti-fungal agents, anti-yeast agents, and anti-viral agents); and (ii) treating or preventing bacteria- mediated infections of the gastrointestinal tract by use of the aforementioned probiotic bacterial strains with or without the concomitant administration of antibiotics. While the primary focus is on the treatment of gastrointestinal tract infections, the therapeutic compositions of the present invention may also be administered to buccal, vaginal, optic, and like physiological locations.
[0019] Even though it is known that probiotics possess anti-proliferative or pro- apoptotic activities in gastrointestinal cancers there are probiotic formulation with specific combination of micro-organisms that helps in improving oral health and to prevent carcinogenesis.
[0020] Hence, there is a need for a formulation of probiotic with combination of specific bacteria to combat cancer and provide oral health benefits to human.
Summary of the invention
[0021] In order to overcome the drawbacks of the state of art, the present invention discloses a formulation of mouthwash solution comprising probiotic for improving oral health and as prophylaxis for oral cancer.
[0022] The formulation of the present invention relates to a formulation of a probiotic alone or in combination of specific beneficial micro-organisms that enhances the oral health, gut health and acts as prophylaxis for cancer.

[0039] The formulation also comprises vitamin, sweetener, flavor and some added and edible colors to enhance the compatibility of the mouthwash solution. The vitamin used is generally vitamin K2.
[0040] The probiotic formulation of the present invention comprises the probiotic as alone or in combination with various combinations and is prepared as a solution to be used as mouth wash. The formulation is free of any chemical or synthetic ingredients thus reducing the risk of adverse effects. [0041] Bacteria used in the formulation of the present invention is unique in enhancing the activity and acts in synergism with other bacteria.
[0042] Acidobacter syzygii, used in the probiotic formulation is generally isolated from the regional traditional dairy products. Acidobacter syzygii exhibits antiproliferative activity in human oral cancer cell lines. The human oral cancer cells treated with Acidobacter syzygii exhibited cytotoxicity and apoptosis indicating the effect of Acidobacter syzygii- The cytotoxic effect of Acidobacter syzygii is due to the intact secretion metabolites of Acidobacter syzygii on cancerous cells but not in normal cells.
[0043] Lactobacillus species exhibits anticancer effects in cancerous cells. Lactobacillus exhibits anticancer activity by altering the interleukin-2 signaling and reduces the proliferation of cancer cells and inducing cell cycle arrest resulting in apoptosis. Lactobacillus salivarius REN downregulates the expressions of cyclooxygenase-2 (COX-2) in vitro. Lactobacillus plantarum also exhibits cytotoxic activity by downregulating the expression of Mitogen- Activated Protein Kinase (MAPK) and upregulates the expression of Phosphatase and Tensin Homolog deleted on Chromosome 10 (PTEN) signaling pathways in cancer cells.
[0044] The following examples are offered to illustrate various aspects of the invention. However, the examples are not intended to limit or define the scope of the invention in any manner.
Example 1: The formulation of Bacillus coagulans probiotic mouth wash solution
[0045] The formulation of the present invention is prepared in a different combination of the probiotics to enhance its efficacy in combination with vitamin, flavors and colors as permitted.
[0046] FIG 2 tabulates the formulation of Bacillus coagulans probiotic mouth wash. The formulation comprises Bacillus coagulans at a concentration of 10 Bn cfu in 5 ml, vitamin K2 at a concentration of 5 mcg, dextranase at a concentration of 10 ppm 30000 u per g, mint flavor, sweetener and color. The volume of the solution is made up to 150 ml with distilled water. The formulation is in the form of solution and is stored in Polyethylene terephthalate (PET) bottle.
[0047] The antic arcinogenic activity of probiotics is based on different mechanisms such as modification of the intestinal microbiota composition, metabolic activity of the intestinal microbiota, production of compounds such as short-chain fatty acids and conjugated linoleic acid that exhibits anticarcinogenic activity, inhibition of cell proliferation and induction of apoptosis in cancer cells, influence on other mutagenic and carcinogenic factors, binding and degradation of carcinogenic compounds present in the intestinal lumen, through immunomodulation and improvement of the intestinal barrier.
[0048] The formulation of the present invention is effective in modifying the intestinal microbiota composition, enhancing immunity and also exhibits anticancer activity. In addition, the formulation also exhibits stability during storage without requiring any additional refrigeration. This is the advantage of the present formulation which makes the Bacillus spores stable at room temperature thus retaining stability. Thus the formulation overcomes the problem of long-term stability during logistics and storage.
[0049] The probiotic formulation of the present invention is prepared in the form of “Safe if swallowed” mouthwash probiotic solution comprising a combination of beneficial bacteria that improves oral health and prevents cancer. In addition to safety, the formulation upon swallowing after oral rinsing, reside in the intestine, thus modulating the gut microbiota along with oral microbiota by increasing the number of beneficial microorganisms and counteracting or antagonizing pathogenic microorganisms. Its positive impact on oral health is observed through reduction in caries-causing microorganisms.
[0050] The metabolites of probiotic oral mouthwash exhibit an impact both on oral health and general health by activating and enhancing the immune system. The formulation enhances both innate and adaptive immunity by promoting the maturation of antigen-presenting cells and altering the production of both immune activating and anti-inflammatory cytokines and chemokines. In addition, they also reduce intestinal inflammation by regulating cytokines, inhibiting active oxygen, and enhancing phagocytosis.
[0051] Upon swallowing, the formulation of the present invention aids in digesting the plant proteins including peas, soybeans, rice and reduce the number of proteins that are transported to the colon thus reducing the possibility of proteins being fermented into toxic metabolites by intestinal microbiota. As a result, the formulation exhibits dual functions firstly enhancing the amino acid bioavailability of plant proteins in the upper intestinal tract and secondly making the microenvironment healthier in colon thus improving the gut health. Moreover, consumption with protein also improves protein absorption and utilization.
[0052] The formulation is not restricted to mouthwash solution it can also be prepared in alternate forms such as a rinse, a strip, a gel, a mouth spray or chewable formulations such as oral dispersible tablet, a chewable gum, a chewable tablet, a lozenge or any other form compliant to patients.
[0053] The formulation of the present invention is swallowable and hence is safe and effective in pediatric population. The formulation does not contain chemicals that are harmful to more than 700 species of microbes that live symbiotically in the oral cavity to maintain optimal oral health.
