Description:
These dipeptide building blocks containing Ser- or Thr-derived oxazolidines (pseudoprolines) proved to be versatile tools for overcoming some intrinsic problems in the field of peptide chemistry. The presence of pseudoprolines within a peptide sequence results in the disruption of β-sheet structures considered as a source of intermolecular aggregation during chain elongation, thus increasing solvation and coupling kinetics in peptide assembly. Therefore, use of pseudoprolines offer new possibilities for accessing large peptides by convergent strategies and chemoselective ligation techniques. Moreover, incorporation of a pseudoproline unit facilitates cyclization of peptides.

Description:
PG 99-465 is a high affinity, selective VPAC2 receptor antagonist. It exhibited a 100-fold preference for the VPAC2 over the VPAC1 receptor. The compound showed partial agonistic activity on the VPAC1 receptor and was inactive on the VPAC2 receptor transfected in CHO cells, as well as on naturally expressed human VPAC2 receptors in the SUP T1 cell line. Dickson et al. observed an agonistic effect of PG99-465 on the human VPAC1 and PAC1 receptors. When applied singly, PG99-465 increased [cAMP](i) at all three hVPAC/PAC receptor subtypes.

Description:
The sequence APRTPGGRR contains a native sequence derived from bovine myelin basic protein amino acids 95-98 (PRTP). The rest of the sequence is not derived from a native sequence, but is a synthetic construct. This substrate is specific for MAP kinases: p44MAPK [extracellular signal-regulated kinase 1 (ERK1)] and p42MAPK (ERK2). It contains the consensus sequence Pro-X-(Ser/Thr)-Pro that is recognized by MAP kinase. This peptide is the most efficient substrate for phosphorylation reaction by ERK. The substrate is phosphorylated by kinases on threonine 97 and can also be phosphorylated by MAPK p38.

Description:
Proctolin, RYLPT, the first insect neuropeptide, was isolated from the cockroach Periplaneta americana. This peptide is synthesized in the central nervous system of several insect species and arthropods and it was originally considered as a visceral muscle neurotransmitter. It later became apparent that proctolin also acts as a neuromodulator affecting myogenic muscle activity or neurally evoked contractions on visceral and skeletal muscles.

Description:
Hepcidin-25 (hepatic bactericidal protein), also referred to as LEAP-1 (liver-expressed antimicrobial peptide) has been independently discovered by two groups in human blood ultrafiltrate and urine. The peptide which is predominantly expressed in the liver, belongs to a new vertebrate family of small antimicrobial peptides that contain 8 cysteine residues and show significant antibacterial and antifungal activity. Further investigations revealed that hepicidin is the principal iron-regulatory hormone in humans. It acts by binding to the iron exporter ferroportin, inducing its internalization and degradation, thereby blocking cellular iron efflux. Nemeth et al. demonstrated that the N-terminal part of the peptide hormone is essential for its activity.
