The novel bis-basic ketones of thioxanthene have antiviral activity when administered orally and parenterally. These compounds are represented by the following formula: ##SPC1## Wherein A is a straight or branched alkylene chain having from 1 to about 6 carbon atoms; and each Y is A. the group ##EQU1## wherein R.sup.1 and R.sup.2 are individually hydrogen or lower alkyl having from 1 to about 4 carbon atoms; or B. the group ##EQU2## WHEREIN N IS A WHOLE INTEGER OF 4 OR 5, AND R.sup.3 is hydrogen or lower alkyl having from 1 to about 4 carbon atoms and can be linked to any one of the carbon atoms of the heterocyclic group; or C. the group ##EQU3## wherein X is oxygen or NR.sup.4, and R.sup.4 is hydrogen or lower alkyl of from 1 to about 4 carbon atoms; or pharmaceutically acceptable acid addition salts of said base. These new compounds can be prepared by several different methods which are described.
噻二硫代黄色素的双碱基酮具有抗病毒活性,口服和注射时均有效。这些化合物由以下公式表示:其中A是直链或支链烷基链,含有1到约6个碳原子;每个Y都是A。该组##EQU1##其中R.sup.1和R.sup.2分别是氢或1到约4个碳原子的较低烷基;或B。该组##EQU2##其中N是4或5的整数,R.sup.3是氢或1到约4个碳原子的较低烷基,可以连接到杂环基的任一碳原子;或C。该组##EQU3##其中X是氧或NR.sup.4,R.sup.4是氢或1到约4个碳原子的较低烷基;或所述碱的药学上可接受的酸盐。这些新化合物可以通过几种不同的方法制备,这些方法已经描述。
