The present invention encompasses methods of using a 5-phenyl-2-furan esters, amides and ketones and compositions thereof to prevent or limit neuronal death or degeneration in a human or lower animal. These methods comprise systemically administering to such human or other animal a safe and effective amount of a compound of the formula: ##STR1## wherein (1) X is halo or nil; and Y is a substituent selected from the group consisting of unsubstituted or halogen-substituted methyl, halo, nitro, amino, and methoxy; and (2) R is R.sup.1 C(O)OH, R.sup.1 C(O)N(R.sup.3).sub.2, N(R.sup.3).sub.2, OR.sup.1 N(R.sup.3).sub.2, R.sup.1 N(R.sup.3).sub.2, N(R.sup.2)R.sup.1 N(R.sup.3).sub.2, or N(R.sup.2)N(R.sup.3).sub.2 ; where R.sup.1 is C.sub.1 -C.sub.3 alkyl which is unsubstituted or substituted with C.sub.1 -C.sub.2 alkyl; R.sup.2 is hydrogen or lower alkyl; and each R.sup.3 is, independently, hydrogen or lower alkyl; or both R.sup.3 groups are connected to form a saturated 5- or 6-membered heterocycle containing 1 or 2 heteroatoms selected from oxygen and nitrogen, and said heterocycle is unsubstituted or substituted with lower alkyl or hydroxy-substituted lower alkyl; or a pharmaceutically acceptable salt thereof.
本发明涵盖使用5-苯基-2-呋喃酯、酰胺和酮及其组合物的方法,以预防或限制人类或低等动物的神经元死亡或退化。这些方法包括向这样的人类或其他动物系统地注入化合物的安全和有效量的公式:##STR1##其中(1)X为卤素或零;Y为取自以下基团的取代基:未取代或卤素取代的甲基,卤素,硝基,氨基和甲氧基;和(2)R为R.sup.1C(O)OH,R.sup.1C(O)N(R.sup.3).sub.2,N(R.sup.3).sub.2,OR.sup.1N(R.sup.3).sub.2,R.sup.1N(R.sup.3).sub.2,N(R.sup.2)R.sup.1N(R.sup.3).sub.2或N(R.sup.2)N(R.sup.3).sub.2;其中R.sup.1为未取代或取代为C.sub.1-C.sub.2烷基的C.sub.1-C.sub.3烷基;R.sup.2为氢或较低的烷基;每个R.sup.3都是独立的,为氢或较低的烷基;或两个R.sup.3基团连接成为一个饱和的5-或6-元杂环,其中包含1或2个从氧和氮中选择的杂原子,并且该杂环未取代或取代为较低的烷基或羟基取代的较低的烷基;或其药学上可接受的盐。
