129 Pharmaceutical compositions and method of use US747995 1976-12-06 US4113879A 1978-09-12 Geraint Jones; David Summers Thomson
Pharmaceutical compositions, containing a 4,4'-dihydroxy-3,3'-triphenylmethanedicarboxylic acid (or an oxidized derivative) as active ingredient, are described and are prepared conventionally in a form suitable for topical administration, e.g., ointment. The compositions are useful for the treatment of inflammatory diseases and inflammatory conditions of the skin. Many of the active ingredients are novel compounds. A representative novel active ingredient is 4"-cyano-4,4'-dihydroxy-5,5'-dimethyl-3,3'-triphenylmethanedicarboxylic acid.

Tanning (hardening) agents in a colloid layer of gelatin or the like are inactive at ordinary temperatures but are activated at temperatures above 70.degree.C. to rapidly tan the colloid in which they are incorporated. Suggested uses are in thermography and photography. Specific examples describe various gelatin layers containing the heat-activated hardeners. The class of useful tanning agents is described by the formula ##SPC1##Wherein the substituents R and R' are selected from hydrogen and halogen atoms and alkyl, carboxyl, alkoxy, formyl, tertiary amino and sulfo radicals. Some specific new compounds of this class are described.

USEFUL PARTIAL OXIDATION PRODUCTS OF DIALKYLNAPHTHALENES, SUCH AS THE NAPHTHALENEDICARBOXALDEHYDE AND THE NAPHTHALENEDICARBOXYLIC ACID ARE PREPARED BY USING MOLECULAR OXYGEN AND A CATALYTIC AMOUNT OF NITRIC OXIDE OR NITROGEN DIOXIDE, THAT IS SUBSTANTIALLY LESS THAN THE STOICHIOMETRIC AMOUNT OF NITROGEN DIOXIDE NECESSARY TO OXIDIZE THE DIALKYLNAPHTHALENES. THE CATALYST IS A COMBINATION OF 0.01 MOLES TO 0.6 MOLE OF THE NITROGEN OXIDE PER MOLE OF DIALKYLNAPHTHALENE AND 0.1 TO 6 WEIGHT PERCENT OF SELENIUM. THE OXIDATIONS ARE CARRIED AT SUPERATMOSPHERIC PRESSURES IN A CLOSED SYSTEM AT TEMPERATURES OF ABOUT 160275* C. OXYGEN IS ADDED IN AT LEAST THE STOICHIOMETRIC AMOUNT NEEDED FOR THE OXIDATIONS. IN THE TEMPERATURE RANGE OF ABOUT 160-225* C. THE DIALDEHYDE IS THE PREDOMINANT PRODUCT; AT ABOUT 225 TO 275* C. THE DIACID PREDOMINATES.
