New Multi-structure SD File Look Up
in the iResearch System

The iResearch System now allows scientists to rapidly search for exact matches to structures contained in an SD file. Using this new tool, scientists can submit an SD file to the iResearch System and look-up the commercially available chemicals in a single analysis. SD files may contain up to 500 structure records. Registered users can click here to log on to their iResearch System account and try this new functionality available under the Search link.


iResearch Library May - 2005 Update
The iResearch Library is ChemNavigator's up-to-date database of commercially accessible screening compounds from international chemistry suppliers. Database licenses include access to regular updates, sourcing information, and ChemNavigator's optional Chemistry Procurement Service. The database may be licensed on CD/DVD ROM or accessed through an on-line iResearch System subscription.

iResearch Library Key Statistics: The iResearch Library tracks chemistry used for drug discovery. Many samples available through the system conform to drug-like molecular weight and cLogP ranges.

More than just screening compounds, the iResearch Library also tracks Building Blocks, Natural Products, and a growing list of Reagents and Fine Chemicals.
The iResearch Library sample count has grown substantially over the past 36 months. Updates to the database are sent to clients on a quarterly basis. These updates provide information on new unique substances added to the database and samples that are no longer available.


Academic Access Program Continues to Grow
The Academic Access Program provides free access to ChemNavigator software and database products to qualifying academic researchers for use in noncommercial research projects. We would like to welcome an additional new member:

East Carolina University
John Whitlow an undergraduate chemistry student under the supervision of Chemistry Professor Dr. Yumin Li, is employing ChemNavigator's iResearch Library and 3DPL as part of a research project to find molecules with an affinity for the active binding site of S100B that is implicated in disrupting p53 function. The iResearch Library database will be docked into the pre-calculated binding pocket of S100B. Additional plans include performing follow up studies to test candidate molecules generated in this study for ADME properties, synthesizability, and energy simulations using Amber.


Supplier Highlight
New Targeted Libraries From LifeChemicals
LifeChemicals now offers carefully designed Target Oriented Libraries (Kinases, GPCRs, Ion Channels, Proteases and Nuclear Receptors). These libraries can be downloaded form their website www.lifechemicals.com or requested to be sent on a CD. http://www.lifechemicals.com
