The present invention is non-provisional filing of U.S. provisional patent application Nos. 62/516,083 filed on 6 Jun. 2017 and 62/516,077 filed on 6 Jun. 2017. The invention in general relates to biological applications of extracellular metabolite isolated from With increase in age, the human skin is subjected to many changes which include wrinkling, sagging and increased laxity that visibly reveal the signs of aging. There are many intrinsic and extrinsic factors that affect skin aging such as hormones, skin-associated microflora, skin pH, reduced stratum corneum lipid content, decreased absolution of reactive oxygen species (ROS), greater metalloproteinase activity, desiccation, laxity, fine wrinkles, and atrophy of the skin. Of the above factors, many are natural and cannot be altered. There are several other factors that cause premature skin aging and can be influenced to induce graceful skin aging. Prevention of skin aging is now being targeted widely by the industry players in the field of cosmetics and there is now an increased requirement for natural products that prevent skin aging. Probiotics are now being currently used in the skin care industry due to the health benefits they provide. The role of probiotics in aging, beauty, photodamage, and skin health are well described in the following prior art documents:
Both probotics and their extracellular metabolites are now being incorporated into skin care products (Katie Schaefer, Anti-aging Probiotic from It is the principle objective of the invention to disclose the anti-aging activity of a composition containing extracellular metabolite preparation of It is another objective of the invention to disclose the anti-glycation activity of a composition containing extracellular metabolite preparation of The present invention fulfills the above mentioned objectives and provides further related advantages.

The ECM serves as a scaffold to stabilize the skin structure, and also helps in proliferation and metabolic functions of the skin cells. Loss of collagen leads to wrinkles and sagging of skin. The principle of the assay of collagenase inhibition is based on the fact that the substrate DQ™ gelatine is conjugated to fluorecein—a fluorescent compound. In DQ™ gelatine, fluorescence is quenched. DQ™ gelatine is efficiently digested by collagenases to yield a fluorescent compound which can be measured. The increase in fluorescence is proportional to enzyme activity. In the presence of an anti collagenase compound the amount of fluorescence will be decreased for a fixed concentration of enzyme and substrate. Materials Equipment-BMG FLUOstar Optima (fluorescent Microplate reader)
The assay was performed in a 96 well black microtitre plate. Type IV from The percentage inhibition is calculated as follows:— B—Fluorescence in the presence of enzyme.
Results The extracellular metabolite exhibited a dose dependent anti collagenase activity with an IC50at 1.8% (50% inhibition of enzyme activity) ( Isolation of Extracellular Metabolite The extracellular metabolite from Materials and Methods Elastase is one of the matrix metalloproteinases, which digest elastin and other components of the extra cellular matrix and is important both for normal skin development. If this enzyme is not regulated by inhibitor proteins results in wrinkling of skin, premature ageing and carcinogenesis. The Anti-Elastase assay by Enz Chek elastase assay kit determines the elastase inhibitory activity of the products. The assays were done using the EnzChek elastase assay kit. The substrate is DQ elastin soluble bovine neck ligament. DQ elastin is labeled with BODIPY FL dye. The non-fluorescent substrate can be digested by elastase to yield highly fluorescent fragments and in the presence of inhibitor, the fluorescence intensity is quenched. The fluorescence intensity was measured in a microplate reader (emission at 485 nm and excitation at 520 nm.) Materials Equipment—BMG FLUOstar Optima (fluorescent Microplate reader)
The assay was performed in a 96 well black microtitre plate. Elastase enzyme from pig pancreas and DQ Elastin as substrate was used for the assay. Different concentrations of LACTOSPORIN® (50 μl) were pre incubated with 50 μl of elastin substrate (25 μg/ml). 100 μl of the Elastase enzyme solution (final concentration—0.1 U/ml) was added and the fluorescence intensity was measured at Em: 485 nm and Ex: 520 nm after 30 minutes. Enzyme activity of control (buffer) was recorded The percentage inhibition is calculated as follows:— B—Fluorescence in the presence of enzyme
Conclusion The extracellular metabolite exhibited a dose dependent anti elastase activity with an IC50at 1.8% (50% inhibition of enzyme activity) ( Isolation of Extracellular Metabolite The extracellular metabolite from Materials and Methods Advanced glycation end products (AGEs) are generated by the non enzymatic adduct formation between amino groups of proteins (predominantly lysine and arginine) and carbonyl groups of reducing sugar, also known as Maillard reaction. In the early stages, reducing sugars react with free amino groups to form an unstable aldimine compound which undergoes molecular rearrangement to form a stable early glycation product known as Amadori product. In the later stages, glycation process through oxidation, dehydration and cyclization reactions forms the advanced glycation end products also known as AGE. Various structures of AGEs such as Nε-(carboxymethyl)-lysine (CML), pyrraline, pentosidine, are known to be associated with degenerative disorders, including aging, diabetes, atherosclerosis Alzheimer's disease, and renal failure. AGEs also implicated in skin aging, accumulate a result of UV irradiation in both senescent and photoaged skin. AGE can be fluorescent as well as non fluorescent in nature. Typically the vesperlysine type of AGE with typical structure as shown below have an excitation at 370-nm and emission at 440 nm, while pentosidine like AGE have an excitation at 335 nm and emission at 385 nm. The principle is based on the fact that ribose sugar and bovine serum albumin are mixed in specific ratio and incubated for 24 hours. Vesperlysine like AGE formed by the reaction was estimated by the increase in fluorescence detected at Ex/Em at 390/460 nm and pentosidines were detected at Ex/Em at 320/405 nm Materials Ribose, Bovine serum albumin, 96 well black microtitre plates Ribose—BSA method: 10 μl of various concentrations of samples were added to 40 μl of BSA (bovine serum albumin, 25 mg/ml stock) and 50 μl of D-Ribose (150 mg/ml stock) was added per well of black 96-well microplate and incubated for 24 h at 37° C. Sample with only BSA is taken as the control. The AGE (advanced glycation end product) formed were detected by the fluorescence at Ex/Em at 390/460 nm for vesperlysine and Ex/Em at 320/405 nm for pentosidine AGE. Results The inhibition of the AGEs vesperlysine and Pentosidine by the extracellular metabolite preparation from Results The extracellular metabolite preparation from Isolation of Extracellular Metabolite The extracellular metabolite from Materials and Methods Dermal fibroblasts are crucial cellular components for the structural integrity of the skin. The extracellular matrix contains collagen, elastin and hyaluron which determine the integrity of skin. Hyaluronan (HA) synthesized by hyaluronan synthases which add UDP-glucosamine and UDP-glucuronic acid residues to a growing HA polymer chain. Transforming growth factor (TGF)-β plays a central role in ECM biosynthesis and controls collagen homeostasis by regulation of both collagen synthesis and degradation. Epidermal growth factor stimulates cell growth and induces collagen synthesis.

Extracted RNA was treated with DNAse I to remove any contaminating DNA and again extracted using phenol:chloroform:isoamyl alcohol extraction (24:25:1). Quality of RNA was determined by checking the absorbance at 260/280 nm using a Nanodrop (Thermo) Quantitative Real Time PCR 2 μg of total RNA was taken for cDNA synthesis using SuperScript III First-Strand Synthesis System (Life Technologies). Quantitative RT-PCR analysis was performed to determine the expression of brown fat specific genes in Roche Light cycler 96 using SYBR Green master mix (Thermo Scientific). β actin was used as a house keeping gene The relative RNA abundance of the genes was normalized to the housekeeping β actin gene and expressed as delta delta CT (equivalent to fold change transformed by Log2).
