Novel bis-basic ketones of xanthene and xanthen-9-one have antiviral activity when administered orally and parenterally. The compounds are represented by the following formula: ##SPC1## Wherein Z is oxygen or H.sub.2 ; each 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, lower alkyl having from 1 to about 6 carbon atoms, cycloalkyl having from 3 to 6 carbon atoms, alkenyl of from 3 to 6 carbon atoms and having the vinyl unsaturation in other than the 1-position of the alkenyl group; or B. the group ##EQU2## WHEREIN N IS A WHOLE INTEGER FROM 4 TO 6, AND R.sup.3 is hydrogen, lower alkyl of 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 a pharmaceutically acceptable acid addition salt thereof. These compounds can be prepared by several different methods.
