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.
含有硫代基团,特别是在蒽环的 2-、7-和 10-位中的一个或多个位置上的硫代基团的蒽林类似物。它们可以通过蒽林衍生物(如 10-溴蒽林)与硫醇或含有可转化为硫代基团的化合物反应制成。另外,还可以还原含有硫代基团的 1,8-二羟基蒽醌。在 1,8-二羟基蒽醌中引入一个或多个核烯丙基,然后通过环氧化或卤化物加成等方法将其转化为活性形式,即可制成反应中间体。然后,中间体可还原成与蒽林相对应的氧化态。
蒽环的 10 个碳原子作为杂环的一部分,可以通过含有各种取代硫代烷基作为 10-取代基的蒽制成其他产品。
这些化合物可用于治疗牛皮癣,并可配制成传统的外用载体,例如凡士林。
