State College, PA – March 19, 2007. QuantumBio Inc., headquartered in State College, PA with offices in Gainesville, FL and Lancaster, PA, has released version 4.5 of its DivCon software suite. Based upon technology originally developed at the Pennsylvania State University in the laboratory of Dr. Kenneth Merz Jr., DivCon is the first to target drug discovery teams at pharmaceutical and biotechnology firms with patent pending applications of linear scaling, quantum mechanics methods.

The innovations in version 4.5, built on those of previous versions, allow the user to more easily integrate the tool with his or her computer aided drug discovery workflow through more robust encapsulation of the Company’s patent pending, QMScore technology; better support for standard coordinate file formats; and improved ease-of-use and stability characteristics.

Dr. Lance Westerhoff, General Manager of QuantumBio says: “We think that version 4.5 is the best DivCon version we have released to date with the usability needs of the user in mind. With version 4.5 and its support for standard file formats, better command line options, and significant implementation and stability improvements, the user is able to access the methods much more quickly.”

In support for the new version, QuantumBio’s Support website has also been updated with new documentation. These pages will continue to be updated in the days and weeks to come with additional resources including further examples and publication abstracts pertaining to the technology. Users are also invited to submit their own experiences and publication abstracts to be included on the site. Please visit http://www.quantumbioinc.com/Support/ for more information.

DivCon Version 4.5 (serial) for Linux, Mac OS X, and IRIX will begin shipping this week to all customers with current software license contracts. The parallel (MPI) version, available for Linux and Mac OS X, will ship early next month. New customers are invited to email sales@quantumbioinc.com or visit http://www.quantumbioinc.com/ concerning licensing opportunities.
