Siderophores are low molecular weight iron chelators, produced by virtually all bacteria, fungi and some plants. They serve to deliver the essential element iron, barely soluble under aerobic conditions, into microbial cells. Siderophores are therefore important secondary metabolites which are very often based on amino acids and their derivatives ...

Corticotrophs were long thought to be a static, homogeneous population of cells that respond positively to hypothalamic stimulation, are inhibited by glucocorticoid feedback and secrete a single biologically active peptide, ACTH(1-39). Our current understanding is that this is an oversimplification and corticotrophs are a dynamic and more complex group

Evidence has accumulated that peptides influence behavior by acting on various structures in the brain. Peptides derived from the anterior pituitary (ACTH, growth hormone), the intermediate lobe (α-MSH), and the posterior lobe (vasopressin) of the pituitary have been shown to modulate conditioned behavior (DE WIED, 1969).

Atrial natriuretic peptide and related peptides
Clinical Chemical Laboratory Medicine, 2007AbstractIn recent years, biomarkers have been recognized as important tools for diagnosis, risk stratification, and therapeutic decision-making in cardiovascular diseases. Currently, the clinical potential of several natriuretic peptides is under scientific investigation.

Selection and application of peptide-binding peptides
Nature Biotechnology, 2000Peptide-binding ligands would be useful for directing reagents to particular epitopes in a protein, the detection of peptide hormones, and many other applications. Here we show that peptides of modest size isolated from a library using a simple genetic assay can act as specific receptors for other peptides.

If we include beta-lactam antibiotics on the grounds that they have the same biosynthetic origin, peptides remain commercially the most important group of pharmaceuticals. However, our increasing knowledge of the genetic and enzymic background to biosynthesis, and of the regulation of metabolite production, will eventually bring a more unified approach

Peptides: Locally Active Peptides (“Vasoactive Peptides”)
1982Angiotensin may be considered the prototype of the so-called vasoactive peptides inasmuch as its predominant effect is on vascular smooth muscle, which is constricted by both direct and indirect effects of the peptide. However, angiotensin may affect contractility of much extravascular smooth muscle with a predominantly, if not exclusively, stimulatory

Peptide Vaccines and Peptide Therapeutics [PDF]
, 2012 Peptide vaccines and Peptide therapeutics are increasingly entering into the focus of pharmaceutical companies. This section is intended to give a broad overview of areas of law that are particularly relevant to the patenting of peptide vaccines and therapeutic peptides as products and in compositions.
