Ab initio molecular orbital calculations at the Hartree Fock level utilizing 6-31G basis set have been performed on small cyclic peptides and peptidomimetic compounds to explore their utility as carriers of levodopa (L-3,4-dihydroxyphenylalanine) to enhance its brain bioavailability. A cyclic peptidomimetic compound with hydrophobic CH2NH backbone is suggested as possible carrier. This carrier ...
Novel strategies to combat orthopedic device related infections are the need of hour. We have synthesized an antibacterial peptidomimetic and characterized its suitability as a non-covalent coating material for bioceramic hydroxyapatite discs.
Peptides have great potential as therapeutic agents, but their use is often limited by susceptibility to proteolysis and their resulting in vivo fragility. In this review, we focus on peptidomimetic approaches to produce protease-resistant peptides with the potential for greatly improved clinical utility. We focus on the use of mirror-image (D-peptide) and ß-peptides as two leading approaches w...
Functionalization of amino acid C- and N-termini with appropriate olefinic moieties allows for the generation of a peptidomimetic via a stereoselective cross-metathesis.
The title compound, cyclo(Phe(1)-d-Ala(2)-Gly(3)-Phe(4)-APO(5)), C26H32N4O5, is the minor diastereoisomer of a cyclic penta-peptidomimetic analogue containing a novel 2-amino-propyl lactone (APO) motif, which displays the same number of atoms as the native amino acid glycine and has a methyl group in place of the carbonyl O atom. The crystal structure presented here allows the analysis of the s...
Among different types of EGFR dimers, EGFR-HER2 and HER2-HER3 are well known in different types of cancers. Targeting dimerization of EGFR will have a significant impact on cancer therapies. A symmetric peptidomimetic was designed to inhibit the protein-protein interaction of EGFR. The peptidomimetic (Cyclo(1,10)PpR (R) Anapa-FDDF-(R)-Anapa)R, compound 18) was shown to exhibit antiproliferative...
Linear peptides containing the sequence WKTSRTSHY were used as lead compounds to synthesize a novel peptidomimetic antagonist of α2β1 integrin, with platelet aggregation-inhibiting activity, named Vipegitide. Vipegitide is a 13-amino acid, folded peptidomimetic molecule, containing two α-aminoisobutyric acid residues at positions 6 and 8 and not stable in human serum. Substitution of glycine an...
Peptidomimetics are classes of molecules that mimic structural and functional attributes of polypeptides. Peptidomimetic oligomers can frequently be synthesized using efficient solid phase synthesis procedures similar to peptide synthesis. Conformationally ordered peptidomimetic oligomers are finding broad applications for molecular recognition and for inhibiting protein-protein interactions. O...
Antibacterial drugs with novel scaffolds and new mechanisms of action are desperately needed to address the growing problem of antibiotic resistance. The periplasmic oxidative folding system in Gram-negative bacteria represents a possible target for anti-virulence antibacterials. By targeting virulence rather than viability, development of resistance and side effects (through killing host nativ...
This minireview provides a brief outline of the peculiar aspects of the preparation of peptidomimetic and pseudopeptidic structures containing heterocycles. In particular novel tricyclic structures are investigated as potential drugs.
