Biography:

Alessandro Dessì is co-author of 59 articles on national and international peer-reviewed reviews, is also co-author of 95 communications to national and international congresses. From 1982 to date, works in the field of chemical research. Up to 2000, the research sector was the transition metal ions (copper, vanadium, cobalt, nickel) and their interactions with ligands of low molecular weight, investigated through spectroscopic and chromatographic techniques. He is currently part of the calculation team, established from 2000 to date, in partnership with Roberto Dallocchio (research technician of Institute of Biomolecular Chemistry of Sassari and in collaboration with Mario Sechi Department of Chemistry and Pharmacy). The specialist knowledge are molecular modeling, virtual screening, docking and molecular dynamics which support the various research groups belonging to the Institute of Biomolecular Chemistry, and different, national and international, research groups. Participation to the Department of Chemical Sciences and Materials Technologies; He was involved in the generation and adaptation of graphical interfaces for the use of different processing programs. Expertise:

  • Calculation models of biologically and pharmacologically active molecules
  • Design and simulation of new bioactive molecules with similar mechanism of action (structure-based drug design)
  • Analysis of the data calculated and pharmacological activities

SCIENTIFIC ACTIVITIES


Interests

The research interest is focused mainly on the calculation of models, by computer facilities. This models can be applied to chemical-biological and pharmaceutical system, adaptation-generation graphical user interfaces for the use of the various processing programs, the design and simulation of new bioactive molecules with similar mechanism of action (structure-based drug design) and finally the analysis of calculated data and pharmacological activities. The calculation concerns the molecular dynamics, quantum mechanics, ab-initio calculation, docking and virtual screening of ligands and macromolecules of biological interest. He deals in particular:

  1. the interface between chemistry, biology and computational sciences, whose aim is to improve understanding of the dynamics of the association of molecules, molecular transitions of proteins and nucleic acids and their interactions with organic molecules of low molecular weight,
  2. design and simulation of new bioactive molecules with similar mechanism of action (structure-based drug design) through methods of molecular dynamics which lead compound pharmacological, conformational analysis of organic ligands with molecular mechanics methods and ab-initio calculation of structures synthesis,
  3. studies of virtual screening and docking relating to possible models antiviral HIV-1 Integrase, Endonuclease, Carbonic Anhydrase, Tyrosinase and Laccase,
