Recently I am researching about ADHESION MOLECULE L1; CELL-ADHESION; INTEGRIN ALPHA(V)BETA(3); CYCLIC RGD; VITRONECTIN-RECEPTOR; MALIGNANT-MELANOMA; DISCOVERY; STRATEGIES; BINDING; DESIGN, Saw an article supported by the National Institute for Medical Research Development (NIMAD) [943185]. Published in ROYAL SOC CHEMISTRY in CAMBRIDGE ,Authors: Hamdan, F; Bigdeli, Z; Balalaie, S; Sewald, N; Michalek, C. The CAS is 98-97-5. Through research, I have a further understanding and discovery of Pyrazine-2-carboxylic acid. Computed Properties of C5H4N2O2
The synthesis of modified RGD peptides and their conjugation to the pyrazine skeleton at their N-terminus are described. To modify and alter the RGD sequence, short bioactive peptides such as FALKF and NGRG were added to the RGD N-terminus. Moreover, the in vitro investigation of these modified peptides, by a cell adhesion assay using the melanoma cell lines M21 expressing alpha(v)beta(3) and M21L lacking alpha(v) expression, was made and interestingly peptide 4 containing the pyrazine moiety with the linear RGDFAKLF sequence gave the best IC50 value with M21 and all the peptides were unable to bind to M21L, demonstrating the selective recognition to alpha(v)beta(3). The results showed pyrazine plays an essential role in the activity of the peptides. From these results, we can suggest that these peptides can affect cancer cells by abrogation of cell adhesion (cell migration).
