DESCRIPTION:

BRIEF SUMMARY
The present invention relates to the use of certain dibenzothiazepinones as antiviral agents.
A group of dibenzothiazepinone derivatives has now been found which show activity as antiviral agents. Thus, according to one aspect, the present invention provides the use of compounds of formula (I) ##STR2## wherein: n is 0, 1 or 2; and or more ring substituent(s) selected from: cycloalkyl or C.sub.1-6 alkoxy (where the alkyl or cycloalkyl moiety may be optionally substituted by one or more substituents selected from halogen atoms and hydroxyl groups); different, each represent hydrogen or C.sub.1-6 alkyl; hydrogen, C.sub.1-6 alkyl or C.sub.3-6 cycloalkyl; above; group may be optionally substituted by one or more substituents independently selected from C.sub.1-6 alkyl, C.sub.1-6 alkoxy, hydroxy, nitro, halogen and amino; and cycloalkyl;
According to one embodiment, the invention provides the use of compounds of formula (I) as defined above in which R.sup.3 represents hydrogen for the manufacture of a medicament for the treatment of a virus disease.
As used herein the term "alkyl" as a group or part of a group means a straight or branched chain alkyl group. Such alkyl groups preferably have 1 to 3 carbon atoms and are more preferably methyl or ethyl, most preferably methyl.
The present invention also provides compounds of formula (I) wherein: or R.sup.1 is hydrogen; and substituent(s) selected from: selected from halogen atoms and hydroxyl groups, or C.sub.1-6 alkoxy substituted by one or more substituents selected from halogen atoms and hydroxyl groups; different, each represent hydrogen or C.sub.1-6 alkyl; hydrogen, C.sub.1-6 alkyl or C.sub.3-6 cycloalkyl; or different, each represent C.sub.1-6 alkyl or one of R.sup.4 and R.sup.5 represents C.sub.1-6 alkyl and the other represents hydrogen; group may be optionally substituted by one or more substituents independently selected from C.sub.1-6 alkyl, C.sub.1-6 alkoxy, hydroxy, nitro, halogen and amino; and substituents selected from halogen atoms and hydroxyl groups, or C.sub.1-6 alkoxy substituted by one or more substituents selected from halogen atoms and hydroxyl groups; different, each represent C.sub.1-6 alkyl or one of R.sup.4 and R.sup.5 represents C.sub.1-6 alkyl and the other represents hydrogen; hydrogen, C.sub.1-6 alkyl or C.sub.3-6 cycloalkyl; C.sub.1-6 alkyl or one of R.sup.4 and R.sup.5 represents C.sub.1-6 alkyl and the other represents hydrogen; group may be optionally substituted by one or more substituents independently selected from C.sub.1-6 alkyl, C.sub.1-6 alkoxy, hydroxy, nitro, halogen and amino; and from: cycloalkyl or C.sub.1-6 alkoxy (where the alkyl or cycloalkyl moiety may be optionally substituted by one or more substituents selected from halogen atoms and hydroxyl groups); different, each represent hydrogen or C.sub.1-6 alkyl; hydrogen, C.sub.1-6 alkyl or C.sub.3-6 cycloalkyl; above; group may be optionally substituted by one or more substituents independently selected from C.sub.1-6 alkyl, C.sub.1-6 alkoxy, hydroxy, nitro, halogen and amino; and cycloalkyl; and that R.sup.2 does not represent methyl when R.sup.1 represents methoxy; or or more ring substituent(s) selected from: cycloalkyl or C.sub.1-6 alkoxy (where the alkyl or cycloalkyl moiety may be optionally substituted by one or more substituents selected from halogen atoms and hydroxyl groups); different, each represent hydrogen or C.sub.1-6 alkyl; hydrogen, C.sub.1-6 alkyl or C.sub.3-6 cycloalkyl; above; group may be optionally substituted by one or more substituents independently selected from C.sub.1-6 alkyl, C.sub.1-6 alkoxy, hydroxy, nitro, halogen and amino; and cycloalkyl; or more ring substituent(s) selected from: cycloalkyl or C.sub.1-6 alkoxy (where the alkyl or cycloalkyl moiety may be optionally substituted by one or more substituents selected from halogen atoms and hydroxyl groups); different, each represent hydrogen or C.sub.1-6 alkyl; hydrogen, C.sub.1-6 alkyl or C.sub.3-6 cycloalkyl; above; group may be optionally substituted by one or more substituents indepe
