The invention provides a memantine derivative or a stereoisomer, a solvate or a pharmaceutically acceptable salt thereof, a pharmaceutical composition of the memantine derivative, and application of the memantine derivative in preparation of drugs for preventing and / or treating central nervous diseases, especially Alzheimer's disease, Parkinson's disease or other neurodegenerative diseases. The compound disclosed by the invention is small in water solubility, can be well prepared into a suspension preparation, has a relatively low dissolution speed in a living body, can achieve the effect of lasting the drug effect for several weeks after single administration, reduces the medication frequency of a patient, improves the compliance of the patient, also ensures the curative effect, and has a relatively good application prospect.

This disclosure relates to reagents such as antisense oligonucleotides that bind to nucleic acids encoding cryptic exons, thereby inhibiting or preventing ELAVL3 cryptic splicing, and to their use in the treatment or prevention of TDP-43-related neurodegenerative or neurological diseases or conditions associated therewith. In some embodiments, the antisense oligonucleotide is a nucleobase polymer capable of reducing the level or expression of intracellular ELAVL3 cryptic exon RNA and increasing or restoring the expression of functional ELAVL3 protein without substantially incorporating the cryptic exon RNA peptide sequence.

The invention relates to a ferroptosis / HDAC6 bifunctional inhibitor and a preparation method and application thereof.The structure of the bifunctional inhibitor is shown in the formula I. The bifunctional inhibitor has the high ROS removing capacity and the lipid peroxidation inhibiting effect. Ferroptosis caused by a ferroptosis inducer can be inhibited; cerebral ischemia and nerve injury caused by cerebral ischemia can be relieved, and symptoms of neurological diseases such as Alzheimer's disease and Parkinson's disease can be relieved. Therefore, the ferroptosis / HDAC6 bifunctional ferroptosis inhibitor provided by the invention can play a synergistic effect through multiple effects to treat ferroptosis related diseases, especially nervous system degenerative diseases, and provides a candidate compound for subsequent drug research and development. .

The invention provides application of an SARM1 enzyme activity inhibitor in treating neurodegenerative diseases or neurological diseases or symptoms. The invention particularly provides a compound as an SARM1 enzyme activity inhibitor and a pharmaceutical composition of the compound.

The invention discloses a clostridium botulinum neurotoxin A receptor binding structural domain mutant with high affinity, and compared with a wild type clostridium botulinum neurotoxin A receptor binding structural domain, the clostridium botulinum neurotoxin A receptor binding structural domain mutant has any one of the following amino acid mutation sites: P1139S, L1154A, G1157L, R1140H, I1148N, L1154G, L1154Y, S1153G and Y1165W. The affinity of the botulinum neurotoxin A receptor binding domain mutant and a receptor SV2 is remarkably higher than that of a wild type, and the mutant and recombinant protein have wide application prospects in the fields of drug delivery, neurological disease treatment, biological detection and the like.
