Dna-modified active small molecule (Synthetic method)

Small molecule active peptide is a kind of biochemical substance between amino acid and protein, smaller than protein content, larger than amino acid content, is a fragment of protein.

Peptides RGD, cRGD,Angiopep vascular peptide, TAT transmembrane peptide, CPP,RVG29

Peptides Octreotide, SP94, CTT2, CCK8, GEII

A “amino acid chain” or “amino acid string” formed by a peptide bond connecting multiple amino acids is called a peptide. Among them, peptides composed of more than 10 to 15 amino acids are called peptides, peptides composed of 2 to 9 amino acids are called oligopeptides, and peptides composed of 2 to 15 amino acids are called small molecule peptides or small peptides.

Molecular peptides have the following characteristics:

(1) Small molecular peptides have simple structure and small content, which can be rapidly absorbed through the small intestine mucosa without redigestion or energy consumption, and have the characteristics of 100% absorption. Thus, the absorption, transformation, and application of small molecule active peptides are efficient and complete.

(2) The direct entry of small molecule active peptides into cells is an important manifestation of biological activity. Small molecular peptides can enter cells directly through the skin barrier, blood-brain barrier, placental barrier, and gastrointestinal mucosal barrier.

(3) Small molecule peptides are highly active, and usually very small amounts can play a large role.

(4) Small molecular peptides have important physiological functions, involving hormones, nerves, cell growth and reproduction. It can regulate the structure of the body system and the physiological role of cells, and maintain the normal physiological activities of human nerves, digestion, reproduction, growth, movement metabolism, circulation and other functions.

(5) Small molecular peptides can not only provide the nutrition required for body growth and development, but also have special biological functions, such as preventing thrombosis, hyperlipidemia, hypertension, delaying aging, anti-fatigue, and improving human immunity.
