Pathologically activated therapeutics for neuroprotection.

Abstract

Many drugs that have been developed to treat neurodegenerative diseases fail to gain approval for clinical use because they are not well tolerated in humans. In this article, I describe a series of strategies for the development of neuroprotective therapeutics that are both effective and well tolerated. These strategies are based on the principle that drugs should be activated by the pathological state that they are intended to inhibit. This approach has already met with success, and has led to the development of the potentially neuroprotective drug memantine, an N-methyl-D-aspartate (NMDA)-type and glutamate receptor antagonist.
