Protein – Protein Interactions In the workshop we worked with in-silico drug discovery and development. In-silico isdrug development through several computer programs. For this we used a structure based-drug design, which is a process that finds new drugs or medications based on knowing thethree-dimensional structure of a biological target. This process involves the design of smallmolecules that complement the shape and charge of the target. There are other techniquesthat can be used for drug discovery such as: Nuclear Magnetic Resonance (NMR) and, X-rayCrystallography. All of these techniques are used for the purpose of finding possible drugtreatments for diseases. These programs help develop ideal environments to find possible drugtreatments; and simultaneously, reduces research time because it works as a filter eliminatingall incompatible drugs. For the workshop we went through the process of drug discovery. Mygroup was in charge of identifying and generating a pharmacophore model using the PyMol andLigand Scouts programs. Our purpose was to identify all the amino acid bonding areas anddevelop a preliminary model for the drug, finding the most efficient path the drug needs tobind properly.
