This report reviews the discovery, design and development of small- and large-molecule drugs that can efficiently cross the BBB. This includes more traditional, medicinal chemistry-based methods, as well as approaches that exploit carrier-mediated transport (CMT) and receptor-mediated transport (RMT). Also covered in the report is use of nanoparticle technology to enable BBB penetration. Further, the report presents in vitro and in vivo assays as well as imaging methods to ascertain a drug’s ability to cross the BBB and reach its target.
The report includes results of a survey of researchers and executives—from corporate and academic organizations—who are active in the CNS drug development area. The survey explores their involvement in BBB-related technologies and programs. The survey results are discussed in terms of what they reveal about the current state of BBB research and the future potential for developing drugs that are able to cross it.
