Filed:

Feb 20, 1973

Appl. No.:

5/334075

Inventors:

Robert W. Fleming - Ann Arbor MI
Arthur D. Sill - Greenhills OH

Assignee:

Richardson-Merrell Inc. - Wilton CT

International Classification:

A01N 900

US Classification:

424248

Abstract:

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.

Assignee:

Richardson-Merrell Inc. - Wilton CT

International Classification:

A01N 900

US Classification:

424248

Abstract:

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.

Appl. No.:

5/677094

Inventors:

Robert Willerton Fleming - Ann Arbor MI

Assignee:

Parke, Davis & Company - Detroit MI

International Classification:

C07D21132

US Classification:

26029384

Abstract:

cis-2,6-Dimethyl-. alpha. ,. alpha. -diphenyl-1-piperidinebutanol; and acid-addition salts. The compounds are pharmacological agents, especially antiarrythmic agents. The compounds can be produced by reacting phenyl lithium or phenylmagnesium halide with cis-. gamma. -(2,6-dimethylpiperidino)butyrophenone or a lower alkyl ester of cis-2,6-dimethyl-1-piperidinebutyric acid; by reacting. alpha. -(3-halopropyl)-. alpha. -phenylbenzyl alcohol with cis-2,6-dimethylpiperidine, or by reacting cis-1- (3-lithiopropyl)-2,6-dimethylpiperidine with benzophenone.
