摘要:
A method and compositions for reducing neuronal damage related to an ischemic condition in a mammalian subject are described. The method includes administration of a voltage-gated calcium channel-blocking compound to the subject, 4-24 hours after the onset of the ischemic condition. Such a calcium channel blocking compound is effective to block norepinephrine release in mammalian CNS neuronal cells and is characterized by specific, high affinity binding to omega-conotoxin MVIIA binding sites. Also disclosed are novel peptide structures useful in the treatment method of the invention.

Compounds of formula I are useful for suppressing appetite, for altering macronutrient preferences, for suppressing obsessive-compulsive behavior, and for inhibiting cravings and substance abuse: ##STR1## wherein R.sub.1 and R.sub.3 are each independently H, hydroxy-alkyl, alpha-cyanoalkyl, SO.sub.3 H, SO.sub.2 NH.sub.2, or C(O)R, where R is OH, NH.sub.2, lower alkoxy, benzyloxy, or aliphatic amino acyl;R.sub.2 and R.sub.9 are each independently H, lower alkyl, benzyl, succinyl, or C(O)R.sub.4, where R.sub.4 is H, lower alkyl, hydrocarboxy-lower alkylene, or lower alkoxycarboxy-lower alkylene; andR.sub.5, R.sub.6, R.sub.7, and R.sub.8 are each independently H, halo, lower alkyl, hydroxy, lower alkoxy, or two adjacent radicals form methylenedioxy or ethylenedioxy;with the proviso that R.sub.1, R.sub.2, R.sub.3, R.sub.5, R.sub.6, R.sub.7, R.sub.8, and R.sub.9 are not simultaneously H.

Compounds of formula I are useful for suppressing appetite, and for altering macronutrient preferences, ##STR1## where the R.sub.2 -R.sub.9 substituents are so selected as to meet a defined quantitative structure activity relationship (QSAR) quantity relating to the partition coefficient of the compound, the net charge on the ring nitrogen, and the radical superfdelocalizability at the position-8 ring carbon.

摘要:
Compositions comprising a compound of formula 1, and optionally a mild stimulant, are effective anorectics, where formula 1 is: ##STR1## and its pharmaceutically acceptable acid-addition salts, wherein X and Y are each independently hydrogen, hydroxy, methyl, ethyl, propyl, methoxy, ethoxy, propoxy, fluoro, chloro, or bromo.These compounds are effective for reducing appetite globally, or at lower dosage, for altering macronutrient preferences and decreasing substance dependence.
