Definitions
- the present disclosure relates to compositions with improved stability of recombinant botulinum toxin light chain proteins.
- Botulinum toxin is a polypeptide product of the anaerobic bacterium Clostridium botulinum , and is a kind of neurotoxin.
- the toxin causes muscle paralysis by blocking the presynaptic release of the neurotransmitter acetylcholine at the mammalian neuromuscular junction.
- botulinum toxin is therapeutically used to treat involuntary muscle movement disorders.
- Involuntary muscle movement disorders include strabismus, idiopathic blepharospasm, hemifacial, torticollis, mandibular dystonia, spastic dysphonia, and various types of muscle spasms and seizures.
- Botulinum toxin is recently used to non-surgically reduce wrinkles on the face by paralyzing the muscles that create wrinkles around the eyes, forehead, and forehead. there is.
- Botulinum toxin is classified into eight neurotoxins, and seven of them (A, B, C, D, E, F, G) can cause nerve paralysis.
- the size of botulinum toxin is about 150 kDa, and it is composed of a complex of non-toxin in addition to botulinum toxin protein.
- the size of each complex can be up to 900 kDa depending on the type of toxin.
- the type of action, target, and duration of action vary depending on the botulinum toxin type. Among them, botulinum toxin type A is known as one of the deadly biological agents.
- Botulinum toxin is expressed as a single polypeptide, and is divided into a heavy chain (Heavy chain, H chain) of about 100 kDa and a light chain (Light chain, L chain) of about 50 kDa by a reconstitution process after expression. Again, the H and L chains are linked by disulfide bonds. Although they have different targets depending on the botulinum toxin type, in common, the H chain binds to a receptor of a nerve cell and forms an endosome containing the toxin through endocytosis. This endosome allows the botulinum toxin to enter the interior. After entering the cell, the L chain exits the endosome and cuts the SNARE protein in the cytoplasm to suppress the secretion of acetylcholine, resulting in muscle paralysis.
- H chain heavy chain
- L chain Light chain
- protein preparations tend to have poor stability due to protein denaturation, aggregation, and the like.
- the instability of these protein preparations increases with the lapse of storage time of the protein preparation.
- the main purpose in formulating a protein preparation is to maintain the solubility, stability, bioactivity, etc. of the protein.
- bioactivity of enzymes varies greatly depending on their three-dimensional structure.
- purified botulinum toxin crystals are diluted with physiological saline or water, biological activity and pharmaceutical properties are lost.
- Botulinum toxin distributed for pharmaceutical purposes is usually a toxin complex comprising a non-toxin protein and a botulinum toxin protein molecule.
- the non-toxin protein serves to stabilize the botulinum toxin molecule in the toxin complex and protect it from denaturation, thereby protecting the activity of the botulinum toxin.
- it is necessary to have a toxicity attenuation process and skin permeability. Therefore, there has been a demand for the development of a composition capable of maintaining the activity of a botulinum toxin with only the L chain, rather than in the form of a toxin complex with a non-toxin protein.
- the light chain of botulinum toxin is an endopeptidase that can hydrolyze peptide bonds.
- Botulinum toxin type A cleaves SNAP-25 among the SNARE proteins. Therefore, it can be said that the inhibition of acetylcholine secretion by neurons is possible with the light chain alone. Taking this into consideration, an attempt was made to develop a composition having only a botulinum toxin light chain having a muscle paralysis effect, preferably in a form capable of transdermal delivery.
