Abstract: Disclosed herein are several methods for promoting nerve regeneration. The methods include administering at least one tyrphostin, or a pharmaceutically acceptable salt thereof. In one non-limiting example, the tyrphostin is tyrphostin A9. These methods can be used to promote nerve growth in the central or peripheral nervous system. The methods are of use in treating neurodegenerative diseases, such as Parkinson's disease, or in treating the transaction of a partial or complete transaction of a nerve in the peripheral or central nervous system.
