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.
噻二氢黄色素的双碳基酮类小说物质在口服和注射时具有抗病毒活性。这些化合物由以下公式表示:##SPC1## 其中A是直链或支链烷基链,具有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分别是氢或具有1到约4个碳原子的低烷基;或B.该组##EQU2##其中N是4或5的整数,R.sup.3是氢或具有1到约4个碳原子的低烷基,并且可以连接到杂环基的任何一个碳原子;或C.该组##EQU3##其中X是氧或NR.sup.4,R.sup.4是具有1到约4个碳原子的氢或低烷基;或所述碱的药物可接受的酸加成盐。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。
