    摘要: This invention relates to a novel class of substituted dihydroimidazo [1,2-α] quinoxaline derivatives of the formula
    wherein
    R' is C 1 -C 6 alkyl, benzyl, phenyl, a
    group, a
    group or a
    group wherein R 4 is C 1 -C 6 alkyl, and R 6 is C 1 -C 8 alkyl, ami- nome-
    thyl, pyridinyl, phenyl, halophenyl or a
    group wherein R 8 is C 1 -C 6 alkyl; R 2 is phenyl or substituted phenyl having 1 or 2 substituents selected from the class consisting of halo or C 1 -C 6 alkoxy; R 3 is hydrogen or halogen; and
    and to pharmaceutical compositions containing such compounds. The compounds and compositions are effective as anti-anaerobic agents.

    摘要: There is disclosed a photographic element comprising a support having thereon a layer containing an anilino-type magenta coupler, wherein said layer comprises an organic solvent having a dielectric constant of not greater than 6.5 and a metallic complex having the following formula (1), (11) or (III) :
    wherein M is nickel, copper, cobalt, palladium or platinum; X, and X 2 each is hydrogen, sulfur or -NR 5 , wherein R 5 is hydrogen or an alkyl, aryl or hydroxyl radical; X 3 is a hydroxyl or mercapto radical; Y is oxygen or sulfur; R 1 , R 2 , R 3 and R 4 each is hydrogen atom, a halogen, a cyano radical, or an alkyl, aryl cycloalkyl or heterocyclic radical which each is bonded directly or through a divalent combining radical to a carbon atom, provided at least one of the R 1 -R 2 and R 3 -R 4 combinations is allowed to form a 5- or 6-member cyclic ring by combining with the carbon atoms which are bonded with each other; and z is a compound coordinatable to M. By incorporating of such a metallic complex compound there can be improved the light resistance of a dye image formed with said photographic element.
