Opis:
Hydrogen bonds and charge-charge interactions, determined by molecular electrostatics, play essential role in biopolymer-ligand associations. Accordingly, electrostatics is crucial in the qualitative and quantitative characterisation of the binding of drugs to their target molecules. In the following, we will give an account on the role of molecular electrostatics in a drug design, laying emphasis on our own work. We will survey the most important computation methods of molecular electrostatic potentials, then outline basic aspects of molecular recognition: steric, electrostatic and hydrophobic complementarity. On the basis of the complementarity, we will also define molecular similarity and discuss various applications of these concepts to the treatment of protein-ligand interactions and a rational drug design. Special attention will be paid to a receptor mapping and to a comparative molecular field analysis, with some our recent applications. A further important point will be the molecular electrostatic field (potential gradient) as a hydrophobicity measure. We will argue that the hydrophobic complementarity and similarity can be treated on the basis of matching regions of the interacting molecules that are characterised by a similar magnitude of the electrostatic field. The concept of the electrostatic complementarity will be extended to enzyme-substrate interactions, providing a firm basis for the quantitative estimation of catalytic rate enhancement.

Opis:
Opioid receptors play the pain control function in the body. Most of the research is carried out to find the most effective analgesic. The earliest analgesic is morphine, however, unfortunately it has many side effects [Mizoguchi H et al. 2003 J. Pharmacol Sci. 93 423]. At a later time dermorphin was discovered as another potent analgesic [Mont ecucchi P C et al. 1981 Int. J. Pept. Protein Res. 17 275]. Unfortunately, this peptide is not resistant to enzymatic metabolism [Kisara K et al. 1986 Br. J. Pharmacol. 87 183; Sasaki Y et al. 1985 Neuropeptides 5 391]. The objective of this study is to search for new opioid analgesics by investigation of interactions between dermorphin analogs and the μ -opioid receptor using molecular modeling methods. MOPR ( μ -Opioid Peptide Receptor) complexes with several ligands (with known biological activity) were modeled to explain how the structure of the complex was related to the biological activity. The investigated dermorphin analogs containing [ DMT1, D -Arg 2 ] (especially tetrapeptides) may become a good alternative for the currently used an algesics.
