¿ SuperGen Inc., of San Ramon, Calif., entered into a Cooperative Research and Development Agreement with the National Cancer Institute for decitabine, the company¿s anticancer compound. SuperGen will provide clinical supplies of decitabine to the NCI, which will launch and support several clinical studies evaluating the potential role of decitabine in a number of solid tumors and hematological malignancies. The studies also will evaluate the role of decitabine¿s unique mechanism of action ¿ the hypomethylation of DNA ¿ in gene regulation and the regulation of growth and redifferentiation of malignant cells. SuperGen intends to start Phase III studies with decitabine for myelodysplastic syndrome and Phase II studies for non-small cell lung cancer.

¿ Symyx Technologies Inc., of Santa Clara, Calif., will collaborate with the Institut fuer Microtechnik Mainz GmbH, of Mainz, Germany, to develop microfluidic and microelectromechanical systems to expand and enhance Symyx¿s platforms for the rapid discovery of new materials. The collaboration aims at creating microreactors on chips that will enable Symyx scientists to evaluate hundreds of catalysts simultaneously under conditions representative of conventional commercial processes. Financial terms were not disclosed.

¿ The Juvenile Diabetes Foundation International awarded a $10 million grant to Children¿s Hospital of Pittsburgh and the University of Pittsburgh to establish the JDF Center for Gene Therapy Approaches to Type I diabetes. Seven research projects will be undertaken, most of which will focus on making islet cell transplants viable for young patients. Islet cells are located in the pancreas and produce insulin. The JDF Center¿s goals are to develop new gene therapy techniques that will increase the supply of islet cells available for transplantation and to protect transplanted islet cells from immune system attack.

¿ University of Washington researchers reported the first direct evidence in mice that protein kinase A (PKA) signaling regulates both alcohol-seeking behavior and sensitivity to some of the effects of alcohol intoxication.
