This invention relates to methods of synthesis of amino acid analogs contained within peptide sequences that is adapted for preparation of peptides containing analogs of basic amino acids lysine and arginine.

The present invention describes a system of gene carrier nanoparticles capable of specifically internalize into cancer cells, eg, cancer cells involved in breast cancer, in vitro and in vivo. The system described allows the introduction of therapeutic genes specifically into target cells through NSTR1 receptor-mediated endocytosis of said system, making it possible to provide treatment for this type of conditions, for example by systemic, intravenous, or in situ administration.

The present invention relates to a multimeric molecule having the general formula (A) or (B): and its use in the diagnosis and / or therapy of tumors

Analogs for CLR / RAMP receptor ligands are provided that have agonist, superagonist, antagonist, super-antagonist, or multiple receptor modulating activity. The analogs can be selective for one or more CLR / RAMP receptors, or can be pan-specific for multiple G protein-coupled receptors.

The invention discloses a neuropeptide and a synthesis method and application thereof, wherein the neuropeptide has an amino acid sequence shown by SEQIDNO:1. According to the amino acid sequence represented by the SEQIDNO:1, valine is used as a first amino acid,-NH2 of the valine is exposed, then the-NH2 of the valine is condensed with-COOH of second amino acid-arginine to form an amide bond, other amino acids are sequentially connected, and finally tyrosine is to obtain the neuropeptide. Compared with the prior art, the neuropeptide has the following advantages: 1. the neuropeptide product can effectively improve defects of experimental animal social memory, and no adverse reaction is observed; 2. functional areas of the neuropeptide is a sequence on an endogenous protein, and cell rejection reaction may not be caused; 3. a signaling pathway activated by the neuropeptide is a known nervous system specific signaling pathway; 4. the product can effectively change the activity and state of neurons; and 5. the essence of the product is an amino acid sequence, is easy to degrade, and may not cause bodily organ loads.

A thio-selective radioactive labeling agent has the following general formula:*R-L-VS,wherein said *R is a radioisotope, L is a linking group, and VS is a vinylsulfone functional group.
