Brain natriuretic peptide-32 (BNP-32), a fragment of the proBNP cardiovascular hormone precursor, exhibits affinity for natriuretic peptide receptors in rat vascular smooth muscle cells (IC50 = 7.3 nM) and promotes cGMP accumulation within these cells (EC50 = 170 nM). Additionally, BNP-32 effectively mediates the relaxation of norepinephrine-precontracted isolated rat aortic strips (EC50 = 6.7 nM). Upon administration at a dosage of 3 µg/kg, it elevates urine and urinary electrolyte outputs and induces hypotension in rats.

Bulevirtide (Myrcludex B) acetate is a virion entry inhibitor which blocks the virion's hepatocyte pathway of entry, the hepatic sodium/taurocholate cotransporting polypeptide (NTCP) receptor. Bulevirtide (Myrcludex B) acetate can be used in HBV and HDV infection studies.

Proinsulin C-peptide human acetate (Proinsulin C-peptide human acetate (33017-11-7 Free base)) is a polypeptide of 31 amino acid residues that links the A and B chains of proinsulin to ensure proper folding, has biological activity and regulates cellular functions.

A group of peptide antibiotics from BACILLUS brevis. Gramicidin (Gramicidine) C or S is a cyclic, ten-amino acid polypeptide and gramicidins A, B, D are linear. Gramicidin is one of the two principal components of TYROTHRICIN.

Bulevirtide (Myrcludex B) is a useful organic compound for research related to life sciences. The catalog number is T35373 and the CAS number is 2012558-47-1.

Colistin A is an antibiotic generated by certain strains of the bacteria Paenibacillus polymyxa. Colistin is a mixture of the cyclic polypeptides colistin A and B and belongs to the class of polypeptide antibiotics known as polymyxins. Colistin is effecti

Fibrinopeptide A, human is a 16-residue short polypeptide cleaved from fibrinogen by thrombin. Fibrinopeptide A, human locates at the NH2-termini of the Aα chain.The conversion of monomeric fibrinogen into polymeric fibrin is mediated by thrombin, which b

Brain Natriuretic Peptide (BNP) (1-32), rat is a 32 amino acid polypeptide secreted by the ventricles of the heart in response to excessive stretching of heart muscle cells (cardiomyocytes).Brain natriuretic peptide (type B natriuretic peptide) was origin

Amylin, a 37-amino acid polypeptide that is structurally related to calcitonin, is secreted from the B cells of the pancreas. Amylin has anoretic effects in rats. Amylin may be responsible for the etiology of insulin resistance of type II diabetes mellitu

PapRIV, a quorum-sensing heptapeptide derived from B. cereus, undergoes synthesis as a 48-amino acid polypeptide. This compound is secreted and then extracellularly processed by NprB proteases into its active form. At concentrations ranging from 1-25 µM, PapRIV triggers the production of IL-6 and TNF-α, as well as NF-κB translocation, specifically in BV-2 microglia cells.

Pentagastrin (ICI-50123) is a synthetic polypeptide that has effects like gastrin when given parenterally, which can cause the secretion and synthesis of salivary proteins.
