3,3',5'-Triiodo-L-thyronine, also known as reverse T3 (rT3), is a thyroid hormone generated by deiodination of the prohormone thyroxine. It is about 1,000-fold less active at the thyroid hormone receptors TRalpha and TRbeta than 3,3',5-triiodo-L-thyronine (Cay-16028) and commonly described as inactive. However, high...

Angiotensin II is a peptide hormone known best as a vasoconstrictor with central roles in chronic hypertension, heart failure, and stroke. It is an octapeptide typically generated by the removal of two residues from angiotensin I by angiotensin-converting enzyme (ACE). Angiotensin II is a ligand for at least two...

Glucagon is a peptide hormone produced from proglucagon in pancreatic alpha cells that has a role in the regulation of glucose metabolism. Pulsatile application of glucagon to rat hepatocytes stimulates glucose production ex vivo. It also stimulates glucose output from perfused rat livers via increases in...

Tentoxin is a cyclic tetrapeptide first isolated from the plant pathogen A. alternata. It is an herbicide that inhibits chloroplast development, resulting in chlorotic tissue. Tentoxin is selectively phytotoxic, as it kills a number of important weeds at concentrations that have no effects on several important...

L-Leucyl-L-Leucine methyl ester (LLME) is a lysosomal condensation product that has been reported to be cytotoxic towards natural killer cells and CD4+ and CD8+ T lymphocytes without affecting helper T cells and B cells. It has also been shown to induce death of monocytes, polymorphonuclear leukocytes, and myeloid...

alpha-MSH (11-13) is a peptide fragment of alpha-melanocyte-stimulating hormone (alpha-MSH, Item No. 29923), a neuropeptide with anti-inflammatory and immunomodulatory activity. It is bactericidal against methicillin-resistant S. aureus (MRSA) with ~10% survival when used at a concentration of 1 µM. alpha-MSH...

Xenin-25 is an endogenous peptide and a neurotensin (NTS) receptor ligand. It binds to NTS receptors in HEK293 cell membranes expressing the mouse receptor. It is expressed in K cells in the small intestine and co-secreted with glucose-dependent insulinotropic polypeptide (GIP). Xenin-25 (1 µM) stimulates the...
