| Abstract: |
The modeling of interaction process between the new rhodamine derivatives - photoactive fluorescent dye (PFD) with lipid bilayer – analog of native membrane based on palmitoyl-2-oleoyl-sn-glycero-3-phosphatidylcholine (POPC) is studied by the molecular dynamic method with the visualization analysis tools of the obtained results. The supramolecular system containing two PFD molecules (situated on the both sides of the bilayer), 128 POPC and 5258 water molecules. Active binding PFD with POPC begins at about 350 ps and both PFD molecules gravitate to the bilayer center. During the study of the interaction parameters PFD with POPC the radial function of these dye molecules distribution against water has been calculated. The specific features of the dye’s behavior during their movement through the lipid membrane are revealed that is important for cell samples staining in human and animal medicine. |
