A process and pharmaceutical compositions for treating several diseases and conditions which are normally treatable with retinoid like compounds are disclosed where the compound used for the treatment are substantially non-teratogenic and not irritant to the skin. The process is useful for treating female mammals, including humans, who are pregnant or in the child bearing age. An important partial structural feature of the compounds which provides the non-teratogenic effect and lack of irritation of skin is shown by the formula where the partially drawn ring signifies an aromatic ring which may be carbocyclic or heteroaromatic, 6-membered or 5-membered, and may be condensed with another ring. R1 is lower alkyl, Cl, Br, or I, R2 is H, lower alkyl, Cl, Br, or I, and R3 is lower alkyl, Cl, Br, I, or is an ether, thioether, ester, thioester, amine or substituted amine group. |
