A peptidomimetic is a small protein-like chain designed to mimic a peptide. [ 1 ] [ 2 ] They typically arise either from modification of an existing peptide, or by designing similar systems that mimic peptides, such as peptoids and β-peptides .
[7] [8] The largest groups of peptidomimetic consist of β-peptides, γ-peptides and δ-peptides, and the possible monomeric combinations. [8] The amino acids of these peptides only differ by one (β), two (γ), or three (δ) methylene carbons, yet the structural changes were profound. These peptide sequences are highly studied as sequence ...
Prohibitin-targeting peptide 1 (also known as prohibitin-TP01 and TP01; trade name Adipotide) is a peptidomimetic with sequence CKGGRAKDC-GG-D (KLAKLAK) 2.It is an experimental proapoptotic drug [1] that has been shown to cause rapid weight loss in mice [2] and rhesus monkeys. [3]
A stapled peptide is a modified peptide (class A peptidomimetic), typically in an alpha-helical conformation, [2] that is constrained by a synthetic brace ("staple"). [3] The staple is formed by a covalent linkage between two amino acid side-chains, forming a peptide macrocycle. Staples, generally speaking, refer to a covalent linkage of two ...
Peptoids (root from the Greek πεπτός, peptós "digested"; derived from πέσσειν, péssein "to digest" and the Greek-derived suffix -oid meaning "like, like that of, thing like a _____," ), or poly-N-substituted glycines, are a class of biochemicals known as biomimetics that replicate the behavior of biological molecules. [1]
There are a number of different distinct classes of protein mimetics. Antibody mimetic - Molecules that mimic antigen binding activity of antibodies; Peptidomimetic - Small protein-like chains designed to mimic larger peptide.
Murepavadin also known as POL7080 is a Pseudomonas specific peptidomimetic antibiotic. [1] It is a synthetic cyclic beta hairpin peptidomimetic based on the cationic antimicrobial peptide protegrin I (PG-1) and the first example of an outer membrane protein-targeting antibiotic class with a novel, nonlytic mechanism of action, highly active and selective against the protein transporter LptD of ...
Processing of the amyloid precursor protein. BACE1 is the major beta secretase for the generation of amyloid-β peptides in the neurons. [9]Generation of the 40 or 42 amino acid-long amyloid-β peptides that aggregate in the brain of Alzheimer's patients requires two sequential cleavages of the amyloid precursor protein (APP).
