Title:
AGENT FOR INCREASING TRANSLATION INITIATION FACTOR OR TRANSLATION ELONGATION FACTOR, AND USE THEREOF FOR MEDICAL PURPOSES
Document Type and Number:
WIPO Patent Application WO/2012/014993
Kind Code:
A1
Abstract:
[Problem] The purpose of the present invention is to provide a pharmaceutical preparation for preventing and/or treating various diseases, which comprises a compound capable of increasing a translation initiation factor or a transcription elongation factor or a pharmaceutically acceptable salt thereof as an active ingredient. [Solution] The present inventors made extensive studies for the purpose of solving the problem, and it is found for the first time that the increase in a translation initiation factor (e.g., eIF4A1) or a translation elongation factor (e.g., eEF1A1) is involved in the NGF-induced neurite elongation potentiating activity of minocycline or cilostazol, and the invention has been accomplished.
