A method for positron emission tomography (PET) imaging of LRRK2 in tissue of a subject, the method comprising: administering a compound of formula I, formula II or formula III, or a pharmaceutically acceptable salt thereof to the subject, wherein the compound includes at least one C¹¹ or F¹⁸ label thereon; allowing the compound to penetrate into the tissue of the subject; and collecting a PET image of the CNS or brain tissue of the subject

he present invention relates to novel compounds that inhibit LRRK2 kinase activity, processes for their preparation, to compositions containing them and to their use in the treatment of or prevention of diseases characterized by LRRK2 kinase activity, for example Parkinson's disease, Alzheimer's disease and amyotrophic lateral sclerosis (ALS).

The invention discloses a targeted capturing and sequencing kit for parkinsoncs disease gene mutation detection and application of the targeted capturing and sequencing kit. The target capturing and sequencing kit comprises probes, capable of specifically capturing the parkinsoncs disease in a targeted manner, of 19 pathogenic gene coding regions, ie SNCA, PRKN, UCHL1, PINK1, PARK 7, LRRK2, ATP13A2, GIGYF2, HTRA 2, PLA2G6, FBXO7, VPS35, EIF4G1, DNAJC6, SYNJ1, TMEM230, CHCHD2, VPS13C and RIC3. The probes are applied to targeted capture of sequences of 19 gene coding regions related to the parkinsoncs disease, then high-throughput sequencing and analysis are performed on the captured sequences, rapid screening is achieved, and gene mutation related to the parkinsoncs disease can be effectively detected at one time. When being applied to clinical gene diagnosis, the targeted capturing and sequencing kit has the advantages of rapidness and convenience in detection, high sensitivity, good specificity and the like.

The invention discloses a non-treatment-oriented method for constructing a zebrafish model used for sifting drugs for treating Parkinson's diseases. The method is characterized in that LRRK2 mutationzebrafish is put in 1-5 mM of a hydrogen peroxide solution, and it takes only 3-6 days to construct the zebrafish model. By means of the method, the model for the Parkinson's diseases is constructed in the zebrafish by combining multiple factors such as genes, environments and ageing, and the Parkinson's diseases are simulated in animals with high fidelity; by using the animal model as a medium, relevant micromolecule compounds and genetic engineering recombinant proteins are sifted, and the drugs which are made from the micromolecule compounds and the genetic engineering recombinant proteinsand can obviously avoid deficiency of dopaminergic neurons and lowering of the behavior activeness are obtained. The sifting method is simple, the cost is low, and the stability and reliability are high.
