The present invention relates to natural product extracts that regulate neurotransmitter release.

When the neurotransmitter is discharged, the synaptic vesicle containing the neurotransmitter must be fused with the presynaptic membrane to form a pathway between the two boundaries. The protein that provides the fundamental force of membrane fusion is three protein complexes called SNARE (soluble N- ethylmaleimide-sensitive factor attachment protein receptor).

Membrane fusion between the synaptic vesicles and the presynaptic membrane opens the neurotransmitter exit pathway, involving the t-SNARE complex attached to the target membrane and the v-SNARE attached to the vesicle. t-SNARE is a complex of a protein called Syntaxin 1a and a protein called SNAP-25. These SNARE proteins are twisted like pretzel. The membrane fusion results in rearrangement of lipid bilayers that are well known in the art. Biofilms are strongly pushed against each other, so these membranes are not spontaneously fused and are given a strong force from the outside to overcome the repulsion between the membranes, which is SNARE protein to create a force that is enough to overcome the reaction between the membranes. In other words, the formation of the SNARE complex is a source of force to overcome the intermembrane repulsion, and is a key phenomenon of extracellular excretion including the release of neurotransmitters.

On the other hand, in order to control the relaxation and contraction of muscles, there is a neuromuscular junction (neuromuscular junction) in the upper layer of the muscle, the nerve terminal (nerve terminal) is loaded with synaptic vesicles.

BoNT (Botulinum neurotoxin, abbreviated as Botox) is a protease that cleaves SNARE protein, a key protein involved in neurotransmitter release. Botox cleaves SNARE proteins, blocking neurotransmission and consequently paralyzing the muscle cells that Botox has infiltrated.

Whereas botox blocks neurotransmission by irreversibly cutting the SNARE protein, the so-called "coating botox" is a kind of "competitive inhibitor" that inhibits neurotransmission by inhibiting the formation of the SNARE complex.

The key component of "Bortox" is hexapeptide called Argireline and has the amino acid sequence of EEMQRR (Blanes-Mira et al., International Journal of Cosmetic Science. 24, 303). -310, 2002). This is the site that matches the amino acid sequence of the N-terminal region of SNAP-25. In other words, small hexapeptides are instead inserted at the sites where intact SNAP-25 should bind, thereby preventing intact SNAP-25 from binding to other SNARE proteins, Syntaxin 1a and VAMP2. do.

Argireline, the main ingredient of current Botox products, has a weakness that its effect is uncertain, its price is disadvantageous due to the nature of the synthetic peptide, and it is not consumer friendly. However, the development of neurotransmission suppression using natural product extracts can provide significantly cheaper raw materials than peptide materials, and since it is a natural product, it is more accessible to consumers when developing the final product. It is feed.

The present inventors completed the present invention by using natural product extract to confirm that the inhibition of membrane fusion and the inhibition of SNARE complex formation on SDS-PAGE.

Among the natural products prepared by the method according to Examples 1 to 100, dogwood tree, oyster tree, giraffe, beech, elm tree, urinary tract, ramie, water flower, rock hydrangea, chestnut tree, bodhi tree, bokbunja It was confirmed that the extracts of strawberry, redwood, birch, raspberry, wildberry, redwood and walnut tree inhibit SNARE complex formation involved in neurotransmission pathways.

Experimental Example 1: Membrane Inhibition

In order to search for a membrane fusion inhibitor, the extract obtained in Examples 1 to 100 was tested for the membrane fusion inhibitory effect.

To produce SNARE proteins, SNARE proteins called SNAP25 (NM011428), Syntaxin 1a (AF217197) and VAMP2 (NM012663), respectively, were purified from biologically transformed E. coli Codon (+) RIL, Novagen. First, POPC (62mol%), DOPS (35mole%), NBD-PS (1.5mol%) and the fluorescent substance Rhodamin-PE, 1.5 were used to make liposomes, which are fluorescently labeled microparticles. mol%) was mixed to make 10mM liposomes (v-vesicle), and to make a liposome unlabeled with fluorescent materials, DOPS and POPC were mixed at a molar concentration of 35:65 to 50mM liposomes (t-vesicle) Made. To make a complex composed of purified SNAP25 and Syntaxin 1a, the mixture was mixed at a molar concentration of 1: 1 and reacted at room temperature for 1 hour, followed by mixing at a molar ratio of 100: 1 with a liposomal unlabeled with fluorescent material, and VAMP2. Was bound to a molar ratio of 50: 1 with the liposome containing the fluorescent material. Then, the two types of lyposomes were stirred for 24 hours at 4 ° C. using a 10 KDa dialysis membrane, and then mixed at a ratio of 3: 7 (v-vesicle: t-visicle) to measure the fluorescence intensity (Model name: Fluorescence intensity was measured using SpectraMax M2, manufacturer: Molecular Device. The results are shown in FIG.

In FIG. 1, since the fluorescence intensity means a membrane fusion phenomenon between SNARE proteins, the low fluorescence intensity indicates that the membrane fusion inhibitory effect is excellent.

The red circle is the path through which the control reaction proceeds, and when only methanol is added instead of the extract, the red circle proceeds to about 60% of the maximum fluorescence intensity, and most of the extracts follow a reaction path similar to that of the control.

Figure 1 shows the results of experiments on some natural product extracts in order to search for membrane fusion inhibitors by natural product extracts. Experimental oyster tree (13), giraffe (15), scab (36), pee (42), chestnut flower (53), raspberry (65), cornel (67), walnut tree (95) The effect of reducing membrane fusion was recognized. In addition, extracts of Acacia, Beech, Elm, Ramie, Lilac, Rock Hydrangea, Bodhi tree, Bokbunja Strawberry, Rhododendron, Untree, Raspberry and Acacia extracts inhibited membrane fusion.

The membrane fusion inhibitory effects of various extracts are summarized in Table 2 below. About 43% of the control response was expressed as a reference, and the extracts showing 30-60% were considered to be ineffective when the locust tree, oyster tree, giraffe, beech, elm, scab, and urine, Ramie grass, hydrangea flower, rock hydrangea, chestnut, linden tree, bokbunja strawberry, red tree, birch tree, wild strawberry, cornel, locust tree, walnut tree extract (19 species) were effective.

Experimental Example 2: SDS-PAGE

SNARE complexes form complexes that are strong enough to not be released by SDS. Using this property, SDS-PAGE was performed to confirm the formation of SNARE complex.

Natural product extract complexes formed by mixing SNAP25, syntaxin 1a and VAMP2 proteins, which are purified from E. coli transformed in the same manner as in Experimental Example 1, at a molar concentration (40 μM) of 1: 1: 1, respectively. It was confirmed whether it was suppressed by the addition of. 10 ul of each protein was instilled in a 1 ml tube at regular intervals, 2 ul of natural product extracts were added, mixed quickly using a vortex, and reacted at room temperature for 30 minutes. Upon completion of the reaction, electrophoresis on 12% SDS-PAGE confirmed the formation of SNARE complex. The results are shown in FIG.

The upper number of Figure 2 is the serial number of Table 2, the lower number is presented for easy comparison with the results of the fusion assay.

As a result (see FIG. 2), some of the results were inconsistent with the experimental results of FIG. 1, but oyster trees (13), giraffes (15), beech trees (17), scabs (36), and urinary tract (42) Chestnut (53), wild berries (67), walnut (95), bokbunja strawberry (59) and the like inhibited the formation of SNARE complex.

Figure 3 measured the inhibitory effect of SNARE complexes by concentration in the Kirincho (15), chestnut flower (53), raspberry (65) extract inhibited SNARE complex formation in the results of FIG. These extracts were found to effectively inhibit the SNARE complex in a concentration dependent manner.

Figure 4 was applied in the same manner as the natural product extraction method was measured the effect of inhibiting the formation of SNARE complexes on the extract extracted from each of the giraffe herb using water, ethanol or hexane. As a result, it was confirmed that water and ethanol extract of giraffe grass effectively inhibited SNARE complex. In addition to creeper tree, oyster tree, beech, elm, scab, peeing, ramie, hydrangea, rock hydrangea, chestnut, linden tree, bokbunja strawberry, red tree, birch tree, wild strawberry, cornel and locust tree The water and ethanol extracts of the walnut tree were found to inhibit the formation of SNARE complex involved in the neurotransmitter pathway.

Experimental Example 3: Wrinkle improvement effect

Experimental Example 3 was a wrinkle relaxation measurement experiment. For each production example, after applying 20 mg to 20 people twice a day Comparative Comparative Example 2 and Preparation Example 3 around the eye, the area around the eye was measured. Replica was made using silicone rubber (Silflo) and image analysis was performed using Skin Visiometer (C + K) on the day of 0, 30 and 60 days. The evaluation method was based on three wrinkle measurements: wrinkle improvement (1), slight wrinkle improvement (2), and no wrinkle improvement (3). Table 3 shows the results of the Kirincho methanol extract of natural products. In addition, Figure 5 is a result of confirming the degree of wrinkle relief in the area around the eye.
