Abstract

A heptapeptide, a product of thymopentin and pidotimod, and a synthesis method thereof, belong to the technical field of chemical pharmacy, and the synthesis method is as follows: connecting thymopentin and pidotimod through an amide bond to synthesize heptapeptide through a solid-phase synthesis method. peptide. The beneficial effect is that: pidotimod is an artificially synthesized high-purity dipeptide, which can not only promote non-specific immune response, but also promote specific response. It is a multiphase broad-spectrum immune booster. The carboxyl group of pidotimod and the amino group of thymopentin arginine form an amide bond to connect the two together to form a new compound, because thymopentin starts from the amino terminal of arginine in the metabolic process Therefore, after connecting pidotimod, it is equivalent to protecting the amino terminus, and changing the traditional thymopentin dosage form will have good clinical value.

Description

technical field

[0001] The invention belongs to the technical field of chemical pharmacy. Background technique

[0002] 1. Overview of Thymopentin

[0003] The synthetic thymopentin (TP5 for short) is a fragment of amino acid residues at positions 32-36 of thymopoietin, but it has all the same physiological functions and pharmacological effects as "thymopoietin". Novel immunomodulators with modulating effects. It mainly induces T cells and binds to T cell-specific receptors to increase the level of intracellular cAMP, thereby inducing a series of intracellular responses to regulate immune function. It also has a good anti-aging effect, which mainly works by enhancing the activity of superoxide dismutase in serum. This product is used for the treatment of tumors, immunocompromised and autoimmune diseases.

[0004] 1) Pharmacological effects of thymopentin

[0005] TP5 can normalize the imbalanced immune function of the body and promote the growth and differentiation of t...
