Company Press Release Boston Life Sciences Broadens Prominent Position in Development of Diagnostic Agents for Parkinson's Disease BOSTON--(BUSINESS WIRE)--Dec. 2, 1998--Boston Life Sciences Inc. (NASDAQ: BLSI - news) whose compound, Altropane (TM) is the only diagnostic agent for Parkinson's Disease currently in active advanced human clinical trials, announced that it has initiated a preclinical development program for a newly-synthesized ``second generation'' technetium-based compound (designated O-1506). This compound differs from Altropane in structure and in the advantageous substitution of technetium for I123 as the radio-ligand. ``In both in vitro and in vivo studies, O-1506 appears to demonstrate selectivity, binding characteristics, and brain striatal localization that look outstanding relative to all other reported technetium-based compounds in this class,'' stated Dr. Marc Lanser, Chief Scientific Officer of BLSI. ``Even as Altropane continues to perform exceedingly well in our clinical trials, we believe that the subsequent introduction of a user-friendly, technetium-based Parkinson's diagnostic product has the potential to substantially increase the market for these agents, particularly in early detection of the disease. The ability to eventually follow Altropane to market, if approved, with a second-generation technetium product would, in our view, give BLSI a long-term competitive advantage in this rapidly emerging diagnostic area. While our priority is to continue to focus on commercialization of Altropane in the U.S., we plan to develop O-1506 worldwide because of potentially simpler manufacturing and distribution considerations,'' added Dr. Lanser.
