Neurotrophic Natural Products: Chemistry and Biology [PDF]

Angewandte Chemie International Edition, 2013
AbstractNeurodegenerative diseases and spinal cord injury affect approximately 50 million people worldwide, bringing the total healthcare cost to over 600 billion dollars per year. Nervous system growth factors, that is, neurotrophins, are a potential solution to these disorders, since they could promote nerve regeneration.
