Abstract:
The invention relates, among other things, a preparation comprising Alzheimer's disease antigen (A68), as well as methods of obtaining this purified antigen, and methods of using this purified antigen, for instance, for diagnosing Alzheimer's disease and for detecting human autoantibodies to the Alzheimer disease antigen. The antigen preparation according to the invention is purified in that it is substantially free of immunoglobulin G. The invention further relates to methods of making Alzheimer disease antigens that can be used instead of or along with the A68 antigen preparation (e.g., for diagnosing AD), such as recombinant human tau, tau isolated from various species including human, and phosphorylated recombinant human tau or isolated tau, as well as A68 anti-idiotypic antibodies.
Abstract:
Compounds of the structure ##STR1## where p and q are zero or one, but cannot both be the same, M is a pharmaceutically acceptable cation or a metabolically cleavable group, B is a valence bond or a straight or branched alkylene group, R is alkyl, cycloalkyl or --NR.sup.1 R.sup.2, where R.sup.1 and R.sup.2 are hydrogen, alkyl, cycloalkyl or alkanoyl, and A is optionally substituted carbocyclic aryl, furyl, benzo[b]furyl, thienyl, or benzo[b]thienyl are potent inhibitors of lipoxygenase enzymes and thus inhibit the biosynthesis of leukotrienes. These compounds are useful in the treatment or amelioration of allergic and inflammatory disease states.

Abstract:
Substituted phenyl, naphthyl, and thienyl N-hydroxy urea compounds form a class of potent inhibitors of 5- and 12-lipoxygenase and are thus useful compounds in the treatment of inflammatory disease states where leukotrienes and other products of lipoxygenase enzyme activity are implicated.
