Peptide analogues of disease-associated epitopes were studied for inhibition of experimental allergic encephalomyelitis (EAE) and adjuvant arthritis (AA) in Lewis rats. EAE- and AA-associated analogues were selected as competitors because of their in vitro inhibitory activity on proliferation of encephalitogenic and arthritogenic T cells. Although the EAE-associated competitor had a superior ma...
In our model system, we generated T cell clones specific for the HLA-DR4 (DRB1*0405)-index peptide (YWALEAAAD) complex. Based on response patterns of the T cell clones, analogue peptides containing single amino acid substitutions of the index peptide were classified into three types, agonists, antagonists or null peptides (non-agonistic and non-antagonistic peptides). Subtle structural changes ...
Photodynamic antimicrobial chemotherapy is an attractive and novel therapeutic approach to treat microbial infections. Antimicrobial peptides (AMPs) have the potential specifically target kill microorganism while showing no effect toward mammalian cells. In current study, peptide (GGG(RW)3), analogue of MP-196, was conjugated a zinc phthalocyanine (ZnPc) photosensitizer (PS) for photoinactivati...
abstract background antibiotic resistance makes antimicrobial peptides (amps) agents an alternative for treatment of pathogenic diseases. they are isolated from various animals invertebrates, vertebrates and plants. the present study shows the electrophoretic pattern of protein and peptides from vicia faba seed and reports our first attempt to study the antibacterial activity of vicia faba seed...
OBJECTIVE Prostate cancer cells secrete the unique protease human glandular kallikrein 2 (hK2) that represents a target for proteolytic activation of cytotoxic prodrugs. The objective of this study was to identify hK2-selective peptide substrates that could be coupled to a cytotoxic analogue of thapsigargin, a potent inhibitor of the sarcoplasmic/endoplasmic reticulum calcium ATPase pump that i...
The widespread distribution of cationic antimicrobial peptides capable of membrane fragmentation in nature underlines their importance to living organisms. In the present work, we determined the impact of the electrostatic interactions associated with the cationic C-terminal segment of melittin, a 26-amino acid peptide from bee venom (net charge +6), on its binding to model membranes and on the...
The design of peptide mimetic compounds is greatly facilitated by the identification of functionalities that can act as peptide replacements. The fluoroalkene moiety has recently been employed for that purpose. The purpose of this work is to examine the conformational ramifications of replacing peptide bonds with fluoroalkene moieties, thus generating peptidomimetics. The alanine dipeptide anal...
