Abstract: Anthralin analogues containing a thio-substituent, especially in one or more of the positions 2-, 7- and 10- of the anthralin ring. They may be made by reacting an anthralin derivative (e.g. 10-bromoanthralin) with a thiol or a compound containing a group convertible to a thio-group. Alternatively, a 1,8-dihydroxy anthraquinone containing a thio-substituent may be reduced. Reactive intermediates may be made by introducing one or more nuclear allylic groups into a 1,8-dihydroxy anthraquinone and then converting them into a reactive form, e.g. by epoxidation or halide addition. The intermediate can then reduced to the oxidation state corresponding to anthralin.Additional products having the 10-carbon atom of the anthralin ring as part of a heterocyclic ring, may be made by anthralins containing various substitutes thioalkyl groups as the 10-substituent.The compounds are useful for treatment of psoriasis, and may be formulated in the conventional vehicles for topical application, for example petrolatum.
