Method of treatment with compounds having selective agonist-like activity on RXR retinoid receptors

Claim 1

A process for treating or preventing in a host mammal, one or more of the diseases and conditions selected from the group consisting of dermatoses, malignant hyperproliferative diseases, atherosclerosis and restenosis resulting from neointimal hyperproliferation, non-malignant hyperproliferative diseases autoimmune diseases, immunological disorders, chronic inflammatory diseases, diseases associated with lipid metabolism and transport, dry eye syndrome, for promoting wound healing, and for reversing and preventing the effects of sun damage to skin by administering a pharmaceutical composition containing an effective dose of an active compound wherein the active compound has retinoid-like biological activity and the further biological property that the compound is a selective agonist of RXR retinoid receptor sites in preference over RAR retinoid receptor sites, wherein in an assay conducted to measure the agonist-like binding activity of the active compound to RAR and RXR receptor sites, in which assay binding to RAR receptor sites of the test compound is compared to trans retinoic acid, and the binding to RXR receptor sites of the test compound is compared to 4-(E)-2-(5,6,7,8-tetrahydro-3,5,5,8,8-pentamethylnaphthalen-2-yl)propen-1-yl]benzoic acid, the EC 50 concentration of the active compound in the RXR receptor sites is at least 10 times less than the EC 50 of the active compound in RAR receptor sites, and wherein the active compound is selected from a group consisting of compounds having Formula 1, Formula 2, Formula 3, Formula 4 and Formula 5 ##STR7## where the symbols are defined as follows: R 1 is lower alkyl, Cl, Br, or I; R 2 is H, lower alkyl, Cl, Br, or I; R 3 is lower alkyl, Cl, Br, I, OR 11 , SR 11 , OCOR 11 , SCOR 11 , NH 2 , NHR 11 , N(R 11 ) 2 , NHCOR 11 , or NR 11 --COR 11 ; the R 5 groups independently are H, lower alkyl, Cl, Br, I, lower alkoxy or lower thioalkoxy of 1 to 6 carbons; the R 6 groups independently are H or lower alkyl; A is (CH 2 ) n where n is 0-5, lower branched chain alkyl having 3 to 6 carbons, cycloalkyl having 3 to 6 carbons, alkenyl having 2 to 6 carbons and 1 or 2 double bonds, alkynyl having 2 to 6 carbons and 1 or 2 triple bonds; B is hydrogen, COOH or a pharmaceutically acceptable salt thereof, COOR 8 , CONR 9 R 10 , --CH 2 OH, CH 2 OR 11 , CH 2 OCOR 11 , CHO, CH(OR 12 ) 2 , CHOR 13 O, --COR 7 , CR 7 (OR 12 ) 2 , or CR 7 OR 13 O, where R 7 is an alkyl, cycloalkyl or alkenyl group containing 1 to 5 carbons, R 8 is an alkyl group of 1 to 10 carbons, or a cycloalkyl group of 5 to 10 carbons, or R 8 is phenyl or lower alkylphenyl, R 9 and R 10 independently are hydrogen, an alkyl group of 1 to 10 carbons, or a cycloalkyl group of 5 to 10 carbons, or phenyl or lower alkylphenyl, R 11 is alkyl of 1 to 10 carbons, phenyl or lower alkylphenyl, R 12 is lower alkyl, and R 13 is divalent alkyl radical of 2-5 carbons; the R 14 groups independently are H or lower alkyl.
