Computer-Aided Drug Design Services


 
p53 - MDM2 oncoprotein drug leads derived from virtual high-throughput screens
 
The Bioinformatics Center provides computational resources and staff expertise in Computer-Aided Drug Design. CADD in used in drug discovery, design, and development research. CADD services are available for CSU researchers and PI's in the Rocky Mountain Regional Center of Excellence in Biodefense.
   
The benefits of CADD include:
  -- Quickly identify novel drug compounds and drug leads
  -- Identify new drug analogues
  -- Expand existing lead series compounds
  -- Complement experimental high-throughput screening efforts
  -- Purchase lead compounds directly from fine chemical vendors
   
CADD screening methods include:
  -- Structure-based screens (drug-receptor and protein-ligand docking)
  -- Ligand-based screens (pharmacophore and similarity searches)
  -- Physicochemical based screens (Lipinski's rules)
  -- 3D-shape and 3D-electrostatics based screens
   
The Center maintains numerous small-molecule compound libraries for CADD screens:
  -- Multi-million compound small-molecule libraries;
currently 13M+ compounds
  -- Drug-like, lead-like, and fragment based compounds
  -- Natural products and synthetic compounds
  -- Diversity-oriented and focused sublibraries
  -- Conformers, enantiomers, rotamers, and tautomers for many compounds
   
CADDSoftware
  Currently, the Center utilizes CADD software from OpenEye Scientific Software Inc. OpenEye's software suite is used extensively in academic, government, and commercial drug research. In addition, Mesa Analytics software is used for clustering compound hitlists from virtual screening results. The Center will regularly evaluate other CADD applications, and will consider requests for specific applications from the research community.
   
CADD Hardware
  The Center utilizes its 64-CPU Apple G5 cluster for screening runs, storage of small-molecule compound libraries, bioinformatics analysis, and molecular modeling.
