[0027] The inventors of the present invention have surprisingly found that a composition comprising rosmarinic acid, caftaric acid and Schizotenuin A provides a synergistic effect on GABA transaminase inhibition (see example 1 and 2). As demonstrated in the results (example 1 and 2) by increasing the presence of for schizotenuin A it is possible to reduce rosmarinic and caftaric acids concentration to reach similar benefits. Indeed, schizotenuin A will potentiate the GABA transaminase inhibition of both compounds allowing a synergistically benefit of the association and an overall dose reduction to reach the GABA transaminase IC50.
[0028] As shown in example 3 there is a surprising benefit of the inventive composition to activate the GABA receptors compared to a classical water lemon balm extract. Indeed, at similar concentration the inventive composition activates the GABA receptors with an additional 16% at 3nM and an additional 24% at 10 nM compared to the classical extract (see figure 2).
[0029] This result shown the beneficial benefit of the defined active compounds within the inventive composition and the synergetic benefit of this composition comprising rosmarinic acid, schizotenuin A, caftaric acid and hydroxycinnamic to improve GABA release and or GABA transaminase inhibition.
[0030] The inhibition of the GABA transaminase and / or the activation of the GABA receptors leads the inhibition of neural activities. As a result, various positive effects on the mind and body are observed, including improved sleep, reduced mental and physical stress, lowered anxiety, and enhanced mood (Hou et al., 2023; Liwinski et al., 2023).

[0115] EXAMPLES
[0116] The present invention will be further described by reference to the following, non-limiting examples.
[0117] Anxiety and related neurological disorders often result from low levels of the inhibitory neurotransmitter GABA. A mechanism to increase GABA levels in the brain and potentially control anxiety is to inhibit the enzyme GABA- Transaminase: GABA-T. Key element to modulate sleep, anxiety and stress is GABA content.
[0118] The goal of this study is to develop an in vitro assay to determine the inhibitory concentration IC50 (concentration to inhibit 50% of enzymatic activity) of active compounds present in lemon balm extract (Melissa officinalis L. Lamiaceae family) and to identified synergistically benefit of their uses.
[0119] Example 1: Effect of different compositions on GABA transaminase inhibition
[0120] The aim of this study was to evaluate the IC50 on the GABA transaminase of different compositions Blueness (lemon balm water extract) and the composition of the invention with improved conditions to increase the previously defined active compounds such as hydroxycinnamic acids such as, but not limited, schizotenuin A, rosmarinic acid as well as caftaric acid.
[0121] 1.1. Materials and methods
[0122] Reagents and consumables GABase is a mixture of y-aminobutyrate glutamate aminotransferase (GABA-T, EC 2.6.1.19) and succinic semialdehyde dehydrogenase (SSDH, EC 1.2.1.16) from Pseudomonas fluorescens and was purchased from Merck KGaA, Darmstadt (Germany). One unit will convert 1.0 pmole of y-aminobutyric acid (GABA) to succinic semialdehyde and then to succinate per min with a stoichiometric reduction of 1.0 pmole of NADP+ at pH 8.6 at 25 °C.
[0123] The chemicals sodium hydroxide, sodium sulfate, Trizma HCI, Dithio-l,4-threitol (DTT), GABA, sodium salt of cr-ketoglutaric acid, p-nicotinamide adenine dinucleotide phosphate (NADP-RO) disodium salt, vigabatrin were purchased from Merck KGaA, Darmstadt (Germany). Microplate UV-Star 96 wells with flat bottom UV-transparent Bio-One were obtained from Greiner.
[0124] Microtiter plate assay for GABA
[0125] The reaction mixture contained Tris-HCI buffer with 750 mM sodium sulfate, 10 mM DTT, 1.4 mM NADP+, 2.0 mM cr-ketoglutaric acid and GABase was added to each well of microplate. The extract or standard solution at different concentrations were added to the reaction mixture and then the microplate was incubated for 15 min at 30°C before the addition of 100 mM GABA solution. Microplate was incubated at 30°C for 60 min. The conversion of NADP+ to NADPH was measured every minute in absorbance at 340 nm with a microplate reader Spark 10M from Tecan (Mannedorf, Switzerland) and the change is proportional to GABA-T activity. Vigabatrin is a known inhibitor of GABA-T and was used as the positive control whereas water as the negative control.
[0126] Tested products
[0127] In this experiment, different compositions were tested: Blueness (lemon balm water extract) obtained from Fytexia uand the composition of the invention with increased hydroxycinnamic compounds (such as rosmarinic acid and schizotenuin A) and caftaric acid within the composition.
[0128] Table 1: composition of the tested extracts
[0129] Analysis:
[0130] Quantitative HPLC analysis
[0131] Quantification of rosmarinic acid, hydroxycinnamic acids, schizotenuin A and caftaric acid compounds was performed on an HPLC Agilent 1260 system equipped with UV detection, using a C18 reverse phase column (Zorbax Eclipse Plus C18 - 4.6 x250mm 5pm) and an external standard calibration.
[0132] The mobile phase consisted of 0.01% phosphoric acid in water (Solvent A) / Acetonitrile (Solvent B) with a flow rate 0.7 mL / min and a gradient elution as follows: 0-10min 95%A, 10- 30min 70%A and 30-35min 0%A.
[0133] Samples were dissolved in 50% methanol to 0.8mg / mL, subjected to sonication and filtered through 0.45pm prior to injection.
[0134] UV monitoring was carried out at 330nm.
[0135] 1.2. Results summary:
[0136] All analyses were done using Excel IC50 formula and presented in Figure 1 to provide comparative data in one support.
[0137] The results presented in the figure 1 shows that the inventive composition has an IC50 on GABA transaminase improved by 1,84 fold compared with classical water lemon balm extract. Interestingly, the inventive composition has a relative improved composition of active compounds such as 7.5 more schizotenuin A, 1.5 more rosmarinic acid, 1.5 more hydroxycinnamic acids and an equivalent amount of caftaric acid compared to the classical water extract (Blueness). However, when considering the improvement in GABA transaminase inhibition (1.84 fold) achieved by the inventive composition, the concentrations of these active compounds within the inventive composition were further enhanced. Schizotenuin A showed a 4.08fold improvement, while the required concentration of rosmarinic acid, hydroxycinnamic acids, and caftaric acid decreased by 0.83, 0.81 and 0.54 (Table 2).
[0138] All together these results highlight that the inventive composition contains more active compounds compared to the classical water extract. Interestingly while the GABA transaminase IC50 is reduced by 1.84 the needed concentration of the active compounds appears to be redistributed within the inventive composition suggesting a synergistic benefit of the schizotenuin A increases, linked with rosmarinic and caftaric acids reduction, for which one could benefits from the others. In other words, the active compounds can potentiate each other's to reduce their overall concentration to reach the targeted IC50. (Figure 1 and Table 2).

[0150] All analyses were done using Excel IC50 formula and presented in a table to provide comparative data in one support.
[0151] 2.2. Results summary:
[0152] Table 4: Correspondence of the respective concentration related to the % of inhibition of the GABA transaminase
[0153] The results in table 5 show that 1.1 mM of rosmarinic acid associated with 2.4 mM of schizotenuin A induces 50% of the GABA transaminase inhibition while, similar concentrations are inhibiting the enzyme at 0.1 % and 32.9 % and the needed concentration to reach 50% of inhibition on their own are 6.9 mM and 3.7 mM respectively. In conclusion, the needed combination is allowing to reduce each concentration by 6.3 and 1.5 of rosmarinic acid and schizotenuin A respectively. Therefore, both active compounds in specific concentrations will allow to reduced their individual concentration to reach a similar benefit which demonstrate a synergistic effect of the combination.
[0154] The results in table 5 show that 1.4 mM of rosmarinic acid associated with 9.8 mM of caftaric acid induces 50% of the GABA transaminase inhibition while, similar concentrations are inhibiting the enzyme at 4.6 % and 29.4% and the needed concentration to reach 50% of inhibition on their own are 6.9 mM and 12.3 mM respectively. In conclusion, the needed combination is allowing to reduce each concentration by 4.9 and 1.2 of rosmarinic acid and caftaric acid respectively. Therefore, both active compounds in specific concentrations will allow to reduced their individual concentration to reach a similar benefit which demonstrate a synergistic effect of the combination. Table 5: Correspondence of the respective concentration related to the % of inhibition of the GABA transaminase
[0155] The results in table 6 show that 3.3 mM of caftaric acid associated with 1.1 mM of schizotenuin A induces 50% of the GABAtransaminase inhibition while, similar concentrations are inhibiting the enzyme at 5.6 % and 23.6 % and the needed concentration to reach 50% of inhibition on their own are 12.3 mM and 3.7 mM respectively. In conclusion, the needed combination is allowing to reduce each concentration by 3.7 and 3.4 of caftaric acid and schizotenuin A respectively. Therefore, both active compounds in specific concentrations will allow to reduced their individual concentration to reach a similar benefit which demonstrate a synergistic effect of the combination. Table 6: Correspondence of the respective concentration related to the % of inhibition of the
[0156] GABA transaminase Overall it appears that there is a synergistic effect of the compounds association to reduce the needed quantities to reach GABA transaminase IC50. Taking together the results are showing that by increasing the presence of for schizotenuin A it is possible to reduce rosmarinic and caftaric acids concentration to reach similar benefits. Indeed, schizotenuin A will potentiate the GABA transaminase inhibition of both compounds allowing a synergistically benefit of the association and an overall dose reduction to reach the GABA transaminase IC50.
[0157] Example 3: Effect of different compositions on GABA receptor activation
[0158] The aim of this study was to evaluate the GABA receptor activation (agonist) of different compositions Blueness (lemon balm water extract) and the composition of the invention with improved conditions to increase the previously defined active compounds such as hydroxycinnamic acids such as, but not limited, schizotenuin A, rosmarinic acid as well as caftaric acid.
[0159] 3.1. Materials and methods
[0160] Two compositions, described in table 1, were tested for agonist activity at the human GABA Bla / B2 (FAST-0102A & FAST-0102G) and GABA Blb / B2 (FAST-0122C) receptors, at three concentrations (10, 3 and 1 nM), in triplicate.
[0161] The Cell lines were established as follow:
[0162] Table ?
[0163] On each day of experimentation, reference compounds were tested at several concentrations in duplicate (n=2) to obtain a dose-response curve and an estimated EC50 / IC50 value. Reference values thus obtained for the test were compared to historical values obtained from the same receptor and used to validate the experimental session. For replicate determinations, the maximum variability tolerated in the test was of + / -20% around the average of the replicates Tested products In this experiment different composition were tested: Blueness (classical lemon balm water extract) and the composition of the invention with increased rosmarinic acid, schizotenuin A and caftaric acid within the composition.Analysis:
[0164] Dose-response data from test compounds were analyzed with XLfit (IDBS) software using nonlinear regression applied to a sigmoidal dose-response model. Agonist activity of test compounds is expressed as a percentage of the activity of the reference agonist at its EC1OO concentration
[0165] 3.2. Results summary:
[0166] The figure 2 highlight a benefit of the inventive composition to activate the GABA receptors compared to a classical water lemon balm extract. Indeed, at similar concentration the inventive composition activates the GABA receptors with an additional 16% at 3nM and an additional 24% at 10 nM compared to the classical extract.
[0167] This result brings complementary data regarding the beneficial benefit of the defined active compounds within the inventive composition and the synergetic benefit of this composition comprising rosmarinic acid, schizotenuin A, caftaric acid and hydroxycinnamic to improve GABA release and or GABA transaminase inhibition.
[0168] Example 4. Clinical benefit of the Inventive composition
[0169] A randomized, placebo-controlled, double-blind, single-centre trial was done to determinate the benefit of the inventive solution to reduce stress related impairment (i.e. calmness, alertness, cognitive abilities such as memories and attention) of a healthy population in a stressful situation defined by a highly demanding cognitive tasks occurring 4 times during the days: baseline and then lh, 3h and 5h after the intervention.
[0170] 4.1. Materials and methods
[0171] Participants, healthy men and women aged 18-40 years, completed an online PSS to determine their perceived stress, participants with scores between 14 to 26 indicating moderate stress were invited to take part in the study. If eligible, participants came to an in- person site where they were provided written informed consent before completing a detailed in-person screening to assess medical and health history, habitual diet and lifestyle, and they practiced the cognitive task battery. On the test day (acute) participants attended the laboratory in a fasted state (overnight fast of at least 8 hours) where they received a standard breakfast (2 croissants with butter and a glass of water), followed by a battery of cognitive and mood tasks. Subjects were then being given one capsule of 300 mg of innovative composition or 300 mg of placebo (maltodextrine) with water, and were re-tested on the task battery lh, 3h and 5h later before being allowed to return home. Lunch (a ham or cheese sandwich with a small packet of crisps and a piece of fruit) was be provided after the 3h assessment.
[0172] Subject satisfaction using a 4-point Likert scale, calmness and fatigue ratings using a 9-point Likert scale was given after baseline cognitive overload and at the end of the day after 5h cognitive overload, while other mood assessments (Bond Ladder-VAS and Stress-VAS) were given before and after 1, 3 and 5h cognitive overload time points. Participants were free to consume water as they wished throughout the day, and were free to operate their time as they wished in between test sessions in the available waiting room at the nutrition laboratory.
[0173] A summary of visits including screening are presented in Table 8 below.
[0174] Table 8: Study Design and Number of Required Visits by Each Subject
[0175] Outcomes (Mood)
[0176] Calmness rating will be measured using a 9-point Likert scale
[0177] Various clusters of subjective transient mood will be measured to support the primary outcome of 9-point calmness anchor ratings (CAR). Stress changes will be assessed using a stress visual analogue scale (S-VAS) which measures transient changes in levels of stress, anxiety, calmness and relaxation between ratings 'not at all' to 'extremely.' These scores are then combined into two scores 'stress / anxiety' and 'calm / relaxed' where a higher score (average % along the line) represents more of the respective descriptor.
[0178] Assessment of three mood factors alertness, calmness and contentedness will be captured using a 16 Bond-Lader Visual Analog Scale (BL-VAS) where 100mm scales anchored by various antonyms (e.g. Alert-Drowsy, Lethargic-Energetic) are then clustered into these respective mood factors.
[0179] Changes in Fatigue will be measured via Fatigue Anchor Points (FAP) on a 9-point Likert Scale between '1. Not at all mentally fatigued' and '9. Extremely mentally fatigued'.
[0180] To measure levels of tiredness, mental overload and relaxation scores a subject satisfaction 4-category rate questionnaire from not satisfied at all (score 1) to entirely satisfied (score 4) will capture these satisfaction domains.
[0181] Outcomes (Cognition)
[0182] Several memory and executive function tasks will be presented at baseline, lh, 3h and 5h to determine changes in cognitive ability.
[0183] Attention Network Task (ANT) will be performed to measure executive function and attention. In this task participants respond to the direction of a centrally presented arrowhead by pressing the corresponding left and right arrow keys. Across multiple trials, the target stimulus was either flanked by arrows pointing in the same direction (congruent), or the opposite direction (incongruent). The number of flanking arrows also varies between trials (load). The task will be completed in two blocks. During the second block, participants will be distracted by noise through headphones. The dependent variables will be reaction time and accuracy by changes in congruency, load and noise. In addition, during two blocks of the ANT an oral serial 3 (S3) task will also be performed as a further measure to assess attention and working memory function. In this S3 task participants subtract backwards starting with the number 50 until they can go no further. The S3 performance will be in place as a distractor and the dependent variable will be ANT performance on congruency and load. Immediate word recall (IWR) will be undertaken to measure episodic memory. Participants are visually presented with a sequential list of fifteen words where they are then given 1 minute to type as many words as they can remember. At each sitting of the task, a different word list will be presented which will be matched for linguistic familiarity, concreteness and frequency. The dependent variable will be the number of correctly recalled words.
[0184] A sustained attention task called the Rapid Visual Information Processing (RVIP) task involves presenting a series of digits on a screen in quick succession. The participant will then be required to monitor the digits for sequences of three consecutive even or three consecutive odd digits. To indicate the end of a target sequence, participants will press the space bar as quickly as possible. The dependent variables are reaction time, correct responses and commission errors.
[0185] A Switching task (SWT) will be undertaken to assess executive function. In this task participants are presented with a computerised visual circle with 8 equally spaced radii that form 8 segments, 4 above and 4 below a bold line. A stimulus digit appears sequentially in each segment in a clockwise direction. If the digit was located above the bold line, participants then indicate whether the digit was odd or even using labelled arrow keys (left for odd, right for even). When the digit is below the bold line, participants again use the arrow keys to indicate whether the digit is higher or lower than 5 (left for higher, right for lower). The dependent variables are accuracy and reaction time.
[0186] Delayed Word Recall (DWR) will be completed to assess the level of delayed episodic memory. Participants will be required to type as many words as they can remember from the immediate word recall presentation here the task takes place approximately 30 minutes after the initial presentation. The dependent variable will be the number of correctly recalled words.
[0187] Statistical analysis
[0188] Repeated measures data will be analysed in RStudio v4.0 using linear mixed-effects models (LMMs). This technique can be used to model variance relating to both fixed parameters such as experimental doses and random parameters such as individual differences between subjects, within multiple layers of the same model. The model was adjusted for severity of baseline stress complaints (PSS score). Post-hoc Bonferroni corrected parametric tests such as independent t-tests will be performed to estimate differences between placebo and intervention groups where appropriate.
[0189] 4.2. Results:
[0190] Mood assessment:
[0191] Bond Lader calmness after cognitive demanding tasks:
[0192] The results presented in figure 3 shows that participants who received the placebo tend to reduce their calmness rating score over time (0 hr session / baseline vs 5 hr session: p=0.06) which is not the case for the participants who received the inventive composition.
[0193] Overall, the results highlight the benefits of the inventive composition in maintaining participants' calmness over time during a highly demanding cognitive and stressful journey, where participants need a high level of attention.
[0194] Bond Lader change from baseline expressed as pre-assessment versus after cognitive demanding task:
[0195] The results from figure 4 show a statistically significant difference of calmness between groups at the 5 hr time point (p=0.04) and a statically non-significant trend at the 1 hr time point (p=0.09).
[0196] This result supports the previous outcome and confirms the benefit of the inventive composition in maintaining calmness over time during a highly demanding cognitive and stressful journey, where participants need a high level of attention. In other words, unlike participants who received the placebo, those who received the inventive composition did not demonstrate a decrease of their calmness level during the day.
[0197] Responders assessment expressed as participants who improved their calmness during the day
[0198] Table 9 below represents the percentage of responders from Figure 4. Responders are defined as participants who improved their calmness rating score on the Bond Lader scale during the day compared to baseline (0 hr). While in the placebo group there is a drop of around 10% of responders between the beginning of the tasks (after 1 hr) and the end of the task (after 5 hr), in the inventive composition group, the level of responders over time remains stable at around 60%, compared to around 50% in the placebo group. These results highlight a difference in the percentage of responders between the two groups, reaching a maximum after 5 hr (end of the day), where the inventive composition group has 16% more calmer participants (responders) compared to the placebo group.
[0199] Table 9: Percentage of responders defined as participants who improved their calmness level compared to baseline / pre-assessment level by group and over time.
[0200] Bond Lader contentedness after cognitive demanding tasks:
[0201] The results presented in Figure 5 show that participants who received the placebo experienced a statistically significant reduction in their contentedness rating score over time (0 hr session / baseline vs. 5 hr session: p=0.002), which is not the case for participants who received the inventive composition. Overall, the results highlight the benefits of the inventive composition in maintaining participants' contentedness over time during a highly demanding cognitive and stressful journey, where participants need a high level of attention.
[0202] Bond Lader alertness after cognitive demanding tasks
[0203] The results presented in Figure 6 show that participants who received the inventive solution, unlike those under placebo, were more alert after treatment. Indeed, there was a statistically significant increase in alertness at 1 hr (p=0.003) and 3 hr (p=0.0007) after treatment in the inventive composition group, but not in the placebo group.
[0204] Overall, the results highlight the benefits of the inventive composition in improving participants' alertness over time during a highly demanding cognitive and stressful journey, where participants need a high level of attention.
[0205] Calmness recovery after a cognitive demanding tasks:
[0206] Calmness recovery is expressed as the participants' capability to improve their calmness level before starting a new cognitively demanding task. This is measured as the difference between calmness before a new session versus calmness score after the previous session. The results in Figure 7 demonstrate a statistically significant treatment effect (p=0.047) between the groups, with an overall higher calmness recovery score for participants under the inventive composition compared to those under placebo.
[0207] In summary, the inventive composition improves fast-acting calmness recovery (less than 2 hr between sessions) between two cognitively and stressful demanding sessions.
[0208] - Attention Networking Task performances:
[0209] In this particularly demanding task, participants must focus on the direction of arrows while counting backward by threes, all while being distracted by noise through headphones.
[0210] The results from Figure 8 show a statistically significant difference between groups in the accuracy score at 5 hr after treatment (p < 0.05).
[0211] In summary, during a stressful and cognitively demanding exercise, the inventive composition group demonstrates a higher level of attention compared to the placebo group. Responders assessment expressed as participants who improved their attention in the ANT during the day
[0212] Table 10 below represents the percentage of responders from Figure 8. Responders are defined as participants who improved their attention level compared to baseline (0 hr) during the ANT.
[0213] In the inventive composition group, there is an increase of 12% of responders over time, showing an improvement in attention, reaching a level of 60% of the participants, which is around twice the percentage of responders within the placebo group (33%, 5 hr after consumption). Table 10: Percentage of responders defined as participants who improved their attention compared to baseline by group and over time.
[0214] - Task Switching Task performances:
[0215] During the Task Switching Task, participants need to remember different rules that apply in different situations. This extremely demanding task requires a lot of attention and memory, which are key components of executive function.
[0216] The results from Figure 9 show a statistically significant difference between groups in the accuracy score at 5 hr after treatment (p < 0.05).
[0217] In summary, during a stressful and cognitively demanding exercise, the inventive composition group demonstrates a higher level of attention, memory, and executive function compared to the placebo group.
[0218] 4.3. Summary:
[0219] The study found that in participants who received the inventive composition exhibited significant benefits in mood (calmness, attention, contentedness) and cognitive performance ('attention, memory, executive function) compared to those who received a placebo.
[0220] Specifically, the inventive composition helped maintain calmness and contentedness over time, while the placebo group experienced declines in these areas. Additionally, participants in the inventive group demonstrated improved alertness and calmness recovery between demanding tasks, as well as enhanced performance in attention, memory and executive function.
[0221] Overall, the inventive composition proved effective in supporting participants' emotional stability and cognitive function during stressful situations.
