Abstract: Disclosed are compounds having the structure: wherein, R1 is H, NH2, NH—(C1-C4)alkyl, or N—[(C1-C4)alkyl]2; R2 and R3 are each independently H, (C1-C4)alkyl, or wherein R4 is H, (C1-C4)alkyl, halogen, hydroxy, (C1-C10)alkoxy, cyano, nitro, —NR5R6, or —OCONR7R8; wherein R5 and R6 are each independently H, or a substituted or unsubstituted (C1-C4)alkyl; and wherein R7 and R8 are each independently H, or substituted or unsubstituted (C1-C4)alkyl, or (C1-C10)aryl; and wherein only one of R2 and R3 is H, enantiomers, tautomers, and pharmaceutically acceptable salts of the compounds, pharmaceutical compositions containing such compounds or salts, and processes for their preparation. The subject invention also provides methods of alleviating symptoms of neurologic and inflammatory disorders, methods of preventing oxidation of lipids, proteins, or deoxyribonucleic acids on a cellular level, and methods of protecting human red blood cells from lysis by O2 radicals.

Abstract: Disclosed are compounds having the structure: wherein Z is —OH or —O•; and A is: wherein X and Y are independently NR1 or O, where R1 is H or C1-C4 alkyl; and R2 is H, C1-C4 alkyl or t-butoxycarbonyl, wherein W is C3-C4 alkynyl; and R1 is H or C1-C4 alkyl, or wherein R1 is H, C1-C4 alkyl, or C3-C4 alkynyl; and R3 is H, OH, O(C1-C4 alkyl), or a halogen, optically active enantiomers, pharmaceutically acceptable salts of the compounds, pharmaceutical compositions containing such compounds or salts, and processes for their preparation. The subject invention also provides methods of alleviating symptoms of neurologic, autoimmune, and inflammatory disorders caused by the presence of reactive oxygen species, methods of preventing oxidation of lipids, proteins, or deoxyribonucleic acids on a cellular level, and methods of protecting human red blood cells from lysis by O2 radicals.

Abstract: The present invention provides novel aminoindenes having the structure: wherein n is 1 or 2, R1 is hydrogen, linear or branched chain C1-C8 alkyl or linear or branched chain C1-C8 alkoxy and R2 is hydrogen or a halogen. Such compounds may be used to treat neurodegenerative conditions such as Alzheimer's disease, head trauma, stroke, hypoxia, anoxia, epilepsy, convulsions, seizures.

Abstract: Novel derivatives of 1-aminoindan and their salts are described. Optically active 1-aminoindan derivatives are prepared by reacting a N-benzyl analog of the desired compound with an enantiomer of mandelic acid.
