Description
“SYNERGISTIC HERBAL COMPOSITIONS FOR SARCOPENIA”
Technical field of the invention:
The invention relates to synergistic herbal compositions comprising at least two herbal ingredients selected from the extract(s), fraction(s), phytochemical(s) and mixtures thereof derived from Syzygium cumini, Rubia cordifolia and Mangifera indica for obtaining at least one health benefit selected from treating/alleviating Sarcopenia, preventing muscle loss, improving muscle mass, improving exercise performance, stimulating muscle protein synthesis and improving recovery of muscle functionality after muscle atrophy. The invention also relates to a method of obtaining at least one health benefit selected from treating/alleviating sarcopenia, preventing muscle loss, improving muscle mass, improving exercise performance, stimulating muscle protein synthesis and improving recovery of muscle functionality after muscle atrophy.
Background of the invention
Sarcopenia is age-associated deterioration of muscle mass and function caused by a wide range of physiological and pathological changes ranging from hormonal disorders to loss of subcellular homeostasis. Recent research indicates that mitochondrial dysregulation with advanced age plays a central role in the development of sarcopenia due to the multifactorial functions of this organelle in energy supply, redox regulation, crosstalk with nuclear gene expression and apoptosis (Marzeti, E. et al., Int. J. Biochem. Cell Biol., 2013, 45, 2288-2301). The decline in skeletal muscle mitochondrial capacity with aging has been extensively studied as a contributor to slower walking speed, fatigability, and sarcopenia. Release of pro-apoptotic factors, morphological alterations (fission, swelling), energy stress via reduced ATP, and increased mitochondrial reactive oxygen species (ROS) emission have all been reported during muscle atrophy in preclinical studies (Coen P. M. et al., Front. Physiol., 2019, 9, Article 1883). Treating sarcopenia involves therapeutic interventions to mitigate the loss of
muscle mass via improving mitochondrial function and proteostatic maintenance. These therapies, which include targeting members of the transforming growth factor b (TGF-b) superfamily, testosterone, selective androgen receptor modulators (SARMS), and growth hormone (GH), among others, are currently or have been tested at various clinical trials (Motley, J. E. Calcif. Tissue Int., 2016, 98, 319-333). However, long term use of drug molecules against these targets would result in side effects and this is a major concern. In this regard, there is an urgent need to search for safer alternatives. Herbal products/formulations could be of greater use in this regard as they are known to possess required biological activity with improved safety.
EP 3453398A1 discloses composition containing Vigna angularis var. angularis for increasing muscle mass and enhancing muscular function or exercise performance through an effect of promoting mRNA or protein expression.
KR101919081B1 discloses a composition for improving muscular functions and for preventing or treating muscle diseases containing a human placenta extract as an active ingredient.
Hence, there is a continuous need in the art to provide alternative treatments comprising highly effective herbal compositions for the treatment of Sarcopenia.
Object of the invention:
Therefore, the object of the present invention is to provide synergistic and safe herbal compositions comprising at least two herbal ingredients selected from the extract(s), fraction(s), phytochemical(s) and mixtures thereof derived from Syzygium cumini, Rubia cordifolia and Mangifera indica for obtaining at least one health benefit selected from treating/alleviating sarcopenia, preventing muscle loss, improving muscle mass, improving exercise performance, stimulating muscle protein synthesis and improving recovery of muscle functionality after muscle atrophy.
Another object of the invention is to provide a method of obtaining at least one health benefit selected from treating/alleviating sarcopenia, preventing muscle loss, improving muscle mass, improving exercise performance, stimulating muscle protein synthesis and improving recovery of muscle functionality after muscle atrophy, wherein the method comprises of treating the human with a synergistic and safe herbal compositions comprising at least two herbal ingredients selected from the extract(s), fraction(s), phytochemical(s) and mixtures thereof derived from Syzygium cumini, Rubia cordifolia and Mangifera indica.
Yet another objective of the invention is to provide use of the synergistic herbal compositions of the present inventions for obtaining at least one health benefit selected from treating/alleviating sarcopenia or controlling loss of muscle mass or improving exercise performance or stimulating muscle protein synthesis and/or improving recovery of muscle functionality after muscle atrophy.

Similarly the compositions C-16 to C-36 were also prepared using various solvent extracts of Syzygium cumini, Rubia cordifolia and Mangifera indica as disclosed in experimental section. The compositions (compositions 1-36) were tested in vitro along with the corresponding individual ingredients to evaluate their efficacy in increasing mitochondrial biogenesis activity in comparison with the corresponding individual ingredients. The compositions unexpectedly showed better efficacy compared to the corresponding individual ingredients suggesting synergistic activity between the extracts of Syzygium cumini, Rubia cordifolia and Mangifera indica.
For example, Syzygium cumini 50% aqueous ethanol extract (S.C-1) at 75 ng/mL and Rubia cordifolia 50% aqueous ethanol extract (R.C-1) at 25 ng/mL concentration showed 11.58% and 4.22% increase in Mitochondrial biogenesis respectively over the control. The composition-1 containing Syzygium cumini 50%
aqueous ethanol extract (S.C-1) and Rubia cordifolia 50% aqueous ethanol extract (R.C-1) in the ratio of 3:1 at 100 ng/mL showed 26.05% increase in Mitochondrial biogenesis, which is significantly better than the additive effect 15.80% (11.58%+4.22%) calculated from the increase in Mitochondrial biogenesis showed by the corresponding individual ingredients. The compositions-2 & 3, and composition-5 (C-2, C-3 and C-5) containing these two extracts (S.C-1 and R.C-1) at ratios 2:1, 1:1 and 1:3 respectively also exhibited synergism in increasing mitochondrial biogenesis, when compared to the increase shown by each of their corresponding individual ingredient concentrations as summarized in Table 3.

The composition-6 containing Syzygium cumini 50% aqueous ethanol extract (S.C-1) and Mangifera indica 90% aqueous ethanol extract (M.I-1) in the ratio of 3:1 at 100 ng/mL showed 20.27% increase in Mitochondrial biogenesis, which is significantly better than the additive effect 14.95% (11.58%+-3.37%) calculated from the increase in Mitochondrial biogenesis showed by the corresponding individual ingredients. The composition-7 and composition- 10 (C- 7 and C-10) containing these two extracts (S.C-1 and M.I-1) at ratios 2:1 and 1:3 respectively also exhibited synergism in increasing mitochondrial biogenesis, when compared to the increase shown by each of their corresponding individual ingredient concentrations as summarized in Table 4.
Similarly, Rubia cordifolia 50% aq ethanol extract (R.C-1) at 75 ng/mL and Mangifera indica 90% aq ethanol extract (M.I-1) at 25 ng/mL concentration showed 12.67% and 3.37% increase in Mitochondrial biogenesis respectively over the control. The composition- 11 containing Rubia cordifolia 50% aq ethanol extract (R.C-1) and Mangifera indica 90% aq ethanol extract (M.I-1) in the ratio of 3: 1 at 100 ng/mL showed 22.15% increase in Mitochondrial biogenesis, which
is significantly better than the additive effect 16.04% (12.67%+3.37%) calculated from the increase in Mitochondrial biogenesis showed by the corresponding individual ingredients. The compositions-12 & 14 and composition-15 (C-12, C- 14 and C-15) containing these two extracts (R.C-1 and M.I-1) at ratios 2:1, 1:2 and 1:3 respectively also exhibited synergism in increasing mitochondrial biogenesis, when compared to the increase shown by each of their corresponding individual ingredient concentrations as summarized in Table 5.
The other randomly selected compositions among C16 to C36 containing various extracts of Syzygium cumirti, Rubia cordifolia and Mangifira indica also exhibited synergism in increasing mitochondrial biogenesis, when compared to the increase shown by each of their corresponding individual ingredient concentrations as summarized in Tables 6-7.
Hence, the said compositions (composition 1-36) unexpectedly showed better efficacy in increasing mitochondrial biogenesis when compared to their corresponding individual ingredients suggesting that these individual extract(s) and fiaction(s) have the tendency to show synergism when combined together.

Evaluation of herbal compositions in dexamethasone-induced skeletal muscle atrophy (sarcopenia) in rats: Sarcopenia is the degenerative loss of skeletal muscle mass (0.5-1% loss per year after the age of 50), quality, and strength associated with aging. Sarcopenia is primarily characterized first by muscle atrophy (a reduction in muscle mas(s), along with a reduction in muscle tissue quality, characterized by such factors as replacement of muscle fibers with fat, an increase in fibrosis, changes in muscle metabolism, oxidative stress, and degeneration of the neuromuscular junction and leading to progressive loss of muscle function and frailty. The most important causative factors of Sarcopenia arc aging, prolonged chemotherapy, lack of proper nutrition. For example, a prolonged use of corticosteroids such as Dexamethasone in the treatment of
various pathological conditions including rheumatic problems, skin diseases, severe allergies, asthma, chronic obstructive lung disease etc. results in developing Sarcopenia conditions such as severe muscle atrophy and loss of muscle mass. In an in vivo proof-of-concept study, we have evaluated tire herbal compositions for their ability to ameliorate the typical Sarcopenia conditions in a Dexamethasone-induced Sarcopenia model in Sprague Dawley rats. The effectiveness of the inventive formulation to modulate the body weight, body weight change, grip strength, calf muscle thickness, gastrocnemius muscle weight and thickness and gastrocnemius muscle fiber sizes is summarized in figures I to
VI.
Effect on body weight change: Figure I depicts the mean body weight of the experimental groups at day 12 and the Figure II demonstrates the percent body weight changes at day 12 (from the day 1) in the treatment groups supplemented with herbal compositions. Dexamethasone treatment (G2) significantly reduced the mean body weight (p<0.001) in comparison with normal control (Gl) rats (figure 1); and the change in body weight in G2 is also significant (compared with Gl) at day 12 from beginning of the experiment (day 1). The composition-37, composition-38 and composition-39 supplemented groups showed improvements in their body weight, when compared with the Dexamethasone induced group (G2).
Efficacy of herbal compositions to improve Grip strength: Figure IP demonstrates that supplementation of the herbal compositions improves grip strengths in dexamethasone treated rats. The rats in G2 showed significant reduction (p<0.05) in grip strength, compared with the vehicle control group (Gl). The rats supplemented with composition-37 (G3) and composition-38 (G4) showed significant improvements (p<0.05) in grip strength, compared with the G2 rats, while composition-39 (G5) exhibited moderate increase in grip strength.
Efficacy of herbal compositions supplementation in increasing calf muscle thickness: Figure IV demonstrates that a 12-days supplementation of the herbal compositions enhanced the calf thickness of the dexamethasone treated rats. Dexamethasone treatment (G2) caused significant reduction in calf size (p<0.05), when compared with the vehicle control rats (Gl). The animals in the treatment groups G3, G4 and G5 supplemented with the herbal compositions-37, 38 and 39 respectively showed significantly increased calf sizes in comparison with G2.
The efficacy of the herbal compositions in increasing the gastrocnemius muscle weight and thickness: The results summarized in Figure 5A demonstrates that at the end of the study, the rats supplemented with the compositions had increased gastrocnemius (GAS) weight and improved muscle sizes in comparison with the Dexamethasone treated rats (G2). Dexamethasone treatment significantly (p<0.05) reduced the GAS muscle weight and size in G2 rats. Figure 5A and 5B demonstrate the improvements in muscle weight and size, respectively, in herbal composition supplemented rats, at the end of the study. In comparison with G2, Composition-39 supplementation (G5) significantly improved GAS weight and size, and composition-38 supplemented rats (G4) showed significant improvement (p<0.05) in size and moderate increase in GAS weight. Composition-37 supplemented (G3) rats showed moderate improvements in GAS weight and size at the end of the study.
The efficacy of the herbal formulations supplementation in increasing the gastrocnemius muscle fiber sizes: Figure 6A depicts the representative photomicrographs of the Sirius red stained cross-sections of the gastrocnemius muscle tissues of the rats in groups Gl to G6. Further, the morphometric analysis revealed that the average cross-sectional area (CSA) of G2 was reduced to 87.7% from 100%, the arbitrary value assigned to CSA of the muscle fibers in Gl animals. In comparison with the G2 rats (87.7%), the muscle fiber CSA in G3, G4 and G5 were increased to 89.4%, 107.3%, and 117.1% (p<0.05), respectively. These observations clearly suggest that supplementation of the herbal
formulations increased gastrocnemius muscle fiber sizes in the Dexamethasone induced Sarcopenia rats. Together, these observations strongly indicate that the foimulations alleviated the muscle atrophy and other conditions associated with Sarcopenia in the in vivo preclinical model.

Example 14: Mitochondrial Biogenesis Assay
Mitochondrial biogenesis assay was performed by using an in-cell ELISA kit obtained from Abeam (Cambridge, UK; Cat# abl 10217) following manufacturer’s protocol. The levels of two mitochondrial proteins were measured simultaneously in each well. The two proteins are each subunits of a different oxidative phosphorylation enzyme complex, one protein being subunit I of Complex IV (COX-I), which is mitochondrial-DNA (mtDNA)-encoded, and the other being the 70 kDa subunit of Complex P (SDH-A), which is nuclear DNA (nDNA)-encoded. For the assay, rat skeletal (L6) cells (ATCC, Manassas, VA; Cat# CRL-1458) in DMEM medium (Sigma Cat# D7777) supplemented with 10%FBS were seeded (10000 cells/well) in a 96 well poly L-lysine coated plate and incubated overnight at 37°C in a C02 incubator. Next day, the medium was removed and cells were treated with respective samples at different concentrations. The treatment was repeated every day up to 3rd day. The culture wells receiving 0.2% DMSO were considered as vehicle control. After the treatment period, cells were fixed with 4% paraformaldehyde and probed with primary antibodies (COX-1 and SDH-A). Alkaline phosphatase (AP) and horse radish peroxidase (HRP)- labeled secondary antibodies were used for SDH-A and COX-1 respectively. Finally, AP/HRP development solution was added and measured the absorbance at 405nm and 600nm in a multi-mode spectrophotometer (Spectramax 2e). (COX-I) to (SDH-A) signal ratio was
calculated for all the treatments for analysis of the effect of treatments. The percent increase of mitochondrial biogenesis over control was calculated using the following formula:

Example 16: Evaluation of efficacy of the herbal compositions-37, 38 and 39 to improve the parameters associated sarcopenia in Dexamethasone(DEXA) induced muscle atrophy in Sprague Dawley rats
Induction: Healthy male Sprague-Dawley rats were randomly assigned to five groups (n=7) viz. G1 (control), G2 (Dexa), G3 (Dexa + composition-37;
250mg/kg), G4 (Dexa + composition-38; 250mg/kg) and G5 (Dexa + composition-39; 250mg/kg). From day 1 to day 4, the rats in G3 to G5 received respective supplements; in parallel, the G1 and G2 rats received carboxymethyl cellulose (CMC, 0.5% in water) supplements. The rats in all groups received the supplements through oral gavage. From day 5 to day 12 of the study, the rats in G2 to G5 received 0.1 mg/kg dexamethasone through i.p. route, while the G1 animals received the equivalent volume of sterile normal saline (i.p.). The rats in G1 to G5 received CMC or respective supplements throughout the study. Rats’ body weight was measured on days 1, 5 and 12; grip strength and calf thickness were measured on day 12. The animals were euthanized by CO2 asphyxiation; their gastrocnemius muscles were collected and weighed. Thickness of the gastrocnemius muscle at the mid-central region was measured, and small pieces of the muscle tissues were preserved in 10% buffered formalin for tissue morphometric analysis.
Estimation of percent body weight change: Animal weighing balance (Mettler Toledo, USA) was used to assess their body weights. Body weights were measured on the days 1, 5 and 12. The percent body weight change of the rats was estimated using the following formula:
Percent change in body wt. on day 12 (from day 1) = [(body weight on day 12- body weight on day 1) x 100] / (body weight on day 1). The composition-37 (G3), composition-38 (G4) and composition-39 (G5) showed improvements in their body weight, when compared with the dexamethasone induced group (G2) as summarized in figures I & II.
Estimation of Grip strength: At the end of study, the grip strength of individual animals was measured using a Grip strength meter (Laboratory enterprises; Mumbai; INDIA). Rats were allowed to grasp the grasping bar and pulled back gently in a horizontal plane by the tail with gradually increasing force till the pulling force overcomes the grip strength of the animal. The force applied at the moment the rat leaves its grasp on the grasping bar while pulling by the tail was
recorded as grip strength in Newtons (N). Three trials were conducted and their average was recorded for each animal. The composition-37 (G3) and composition- 38 (G4) showed significant improvements in grip strength, compared with the G2 rats, while the composition-39 (G5) demonstrated increase in grip strength as depicted in figure IP.
Calf and gastrocnemius muscle thickness measurements: The calf and the isolated gastrocnemius muscles from each animal were measured using a Vernier Caliper (Fisher Scientifics, USA), on day 12. Each measurement was repeated thrice and their average value was recorded. The results showed that all the three compositions improved calf thickness as summarized in figure IV and improved in muscle weight (A) and size (B) as shown in figure V.
Histopathological investigation: The mid-central portions of the gastrocnemius muscles were fixed in 10% buffered-formalin, embedded in paraffin. The fixed tissues were sectioned at 5mm thickness in a microtome. The tissue sections were stained with sirius red and examined under a light microscope as summarized in figure VIA. Pixel sizes of the muscle fibers were estimated using Axiovision 4.8 software (Carl Zeiss GmbH, Jena, Germany). A conversion scale of 0.1694 mm per pixel was used to estimate the area of each fiber and represented in mm2. As depicted in figure VIB, these compositions increased gastrocnemius muscle fiber sizes in the Dexamethasone induced sarcopenic rats.
Statistical analysis: The intergroup difference analyses were performed using One-way analysis of variance (ANOVA), and Dunnett’s test was performed to identify the significance using GraphPad Prism Software. P<0.05 was considered as significant.
