The present invention relates to an amphiphilic block copolymer of a hydrophilic block and a hydrophobic block with a terminal hydroxyl group wherein the terminal hydroxyl group of the hydrophobic bock is substituted with a tocopherol or cholesterol group. It also relates to polymeric compositions capable of forming stable micelles in an aqueous solution, comprising the amphiphilic block copolymer and a polylactic acid derivative wherein one or more ends of the polylactic acid are covalently bound to at least one carboxyl group.

This invention provides novel neuroprotective 4-pyrimidineamine derivatives and neuroprotective pharmaceutical compositions comprising 4-pyrimidinamines. This invention also provides methods of using these compositions to prevent ischemic cell death, particularly neuronal cell death, and reduce the likelihood of neuronal cell death in a subject due to a traumatic event. Finally, this invention provides an apparatus for administering to a subject the instant pharmaceutical compositions.
