  • Patent number: 6780853
    Abstract: The invention relates to 3&agr;-hydroxy, 17-(un)substituted derivatives of the androstane series and 3&agr;-hydroxy, 21-substituted derivatives of the pregnane series. These derivatives are capable of acting at a recently identified site on the GRC, thereby modulating brain excitability in a manner that will alleviate stress, anxiety, insomnia, mood disorders that are amenable to GRC-active agents (such as depression) and seizure activity. The steroid derivatives of this invention are those having the general structural Formula: wherein R, R1, R2, R3, R4, R5, R6, R7, R8, R9 and R10 are farther defined herein and the dotted lines are single or double bonds. The structure includes androstanes, pregnanes (R4=methyl), 19-norandrostanes, and norpregnanes (R4=H).

  • Publication number: 20040142983
    Abstract: Disclosed are nitrone compounds and pharmaceutical compositions containing such compounds. The nitrone compounds have one to six additional carbons bridging between the nitrone functionality and the nitrone aryl ring. The disclosed compositions are useful as therapeutics for inflammation-related conditions and analgesia in mammals, such as arthritis, and for neuropathic pain and traumatic injuries such as traumatic brain injury and acute spinal cord injury.

  • Patent number: 5925630
    Abstract: The invention relates to 3.alpha.-hydroxy, 17-(un)substituted derivatives of the androstane series and 3.alpha.-hydroxy, 21-substituted derivatives of the pregnane series. These derivatives are capable of acting at a recently identified site on the GRC, thereby modulating brain excitability in a manner that will alleviate stress, anxiety, insomnia, mood disorders that are amenable to GRC-active agents (such as depression) and seizure activity. The steroid derivatives of this invention are those having the general structural Formula: ##STR1## wherein R, R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5, R.sub.6, R.sub.7, R.sub.8, R.sub.9 and R.sub.10 are further defined herein and the dotted lines are single or double bonds. The structure includes androstanes, pregnanes (R.sub.4 =methyl), 19-norandrostanes, and norpregnanes (R.sub.4 =H).

  • Patent number: 5177248
    Abstract: The present invention is directed toward the preparation of novel polysubstituted fullerenes. The method of forming polysubstituted fullerenes comprises contacting a fullerene with an electrophilic reagent selected from the group consisting of nitronium ion and organic peracid, provided that when the electrophilic reagent is nitronium ion, the fullerene is subsequently contacted with a nucleophilic reagent.
