L-Leucinamide,D-arginyl-D-prolyl-L-lysyl-L-prolyl-L-glutaminyl-L-glutaminyl-D-tryptophyl-L-phenylalanyl-D-tryptophyl-L-leucyl-

Description:

L-Leucinamide, D-arginyl-D-prolyl-L-lysyl-L-prolyl-L-glutaminyl-L-glutaminyl-D-tryptophyl-L-phenylalanyl-D-tryptophyl-L-leucyl- is a complex peptide composed of various amino acids, characterized by its specific sequence of L- and D-amino acids. This compound is notable for its potential applications in biochemistry and pharmacology, particularly in the study of peptide synthesis and protein interactions. The presence of both L- and D-amino acids in its structure may influence its biological activity and stability, as D-amino acids can confer resistance to enzymatic degradation. The CAS number 84676-91-5 uniquely identifies this substance in chemical databases, facilitating research and regulatory processes. Its properties, such as solubility, melting point, and reactivity, would depend on the specific arrangement of the amino acids and their side chains, which can significantly affect the compound's overall behavior in biological systems. Further studies would be necessary to elucidate its specific functions and potential therapeutic applications.

(D-Arg1,D-Pro2,D-Trp7·9,Leu11)-Substance P

CAS: 84676-91-5

Substance P is a tachykinin that is released from the nerve endings of the parasympathetic nervous system. It binds to receptors in the plasma membrane of cells and causes them to release acetylcholine, which is an inhibitory neurotransmitter. Substance P also has been shown to interact with muscle cells and cause contractions. The incubation of Substance P with muscle cells inhibits the release of calcium ions, which reduces the membrane potential and decreases the contractility of these cells.
