  • 3,4-disubstituted phenols-immunomodulating agents
    Patent number: 5258407
    Abstract: Certain 3,4-disubstituted phenols and pharmaceutically acceptable salts thereof are provided which mimic IL-1 activity by inducing IL-2 synthesis and subsequent IL-2 receptor expression. Specifically, the invention provides compounds of Formula I and acid addition salts thereof: ##STR1## wherein Y is ##STR2## NHSO.sub.2 or SO.sub.2 NH where R.sup.4 is H; Z is --O--, --NH--, --NR--, --S--, or other heteroatoms capable of hydrogen bonding with R.sup.4 to give a preferred conformation;R is alkyl;R.sup.1 is --OH;R.sup.2 is H, alkyl, cycloalkyl, aralkyl, substituted or unsubstituted aryl, or a substituted or unsubstituted nitrogen heterocyclic group having 4 to 5 nuclear carbon atoms; andR.sup.3 is a lipophilic moiety.

  • Non-precipitating quinone diazide polymer containing photoresist composition with o-quinone diazide trisester as dissolution inhibitor
    Patent number: 4684597
    Abstract: There is disclosed a photoresist composition comprising a light-sensitive, quinone diazide polymer, a binder and a benzene monomer trisubstituted with a diazo-naphthoquinone-sulfonyloxy group. The composition is improved in that the diazo-naphthoquinone-sulfonyloxy group occupies the 1,2,4-positions on the benzene ring, whereby improved solubility is achieved.

  • Halftone imaging silver halide emulsions, photographic elements, and processes which employ novel arylhydrazides
    Patent number: 4560638
    Abstract: An unballasted arylhydrazide is disclosed the aryl moiety of which is substituted with a group of the formula ##STR1## where one of X and X' represents --NH--, the other represents a divalent chalcogen, and R represents an aliphatic or aromatic residue. The arylhydrazides, when applied to halftone imaging in conjunction with silver halide emulsions, photographic elements, and imaging processes, produce images of improved dot quality and low levels of pepper fog.
