Nuclear Imaging Agent Measures, Monitoring Cathepsin B Activity
A new imaging agent, Cat B 750 FAST, for measuring and monitoring cathepsin B activity associated with disease progression and therapeutic response in vivo was released at the 2009 American Heart Association meeting.
VisEn Medical Inc. said cathepsin B expression is well known as a key biomarker and therapeutic target in a range of diseases, including atherosclerosis, oncology, and arthritis. The new agent is expected to have a significant impact in cardiovascular disease research.
Cathepsin B proteases play an important role in disease progression and host response in several disease areas, and are key biomarkers in assessing and characterizing disease states. The new Cat B 750 FAST agent is designed to complement in vitro and in vivo protease readouts from cell-based assays and VisEn’s existing in vivo agent product lines, providing earlier imaging time points and narrower specificity profiles of cathepsin B within the cathepsin family of proteases.
The new Cat B 750 FAST agent represents an additional protease-sensing agent developed from VisEn’s new FAST (Fluorescent Activatable Sensor Technology) in vivo agent platform. FAST agents are based on high-performance activatable smaller molecules that combine advanced biomarker specificity with optimized biocompatibility and rapid pharmacokinetics. These benefits allow for precise measurement and monitoring of key disease biomarkers in vivo.
