METHODS OF TREATING POXVIRAL INFECTIONS
Provided are methods of treating a disease or condition caused by or associated with a virus belonging to the Poxyiridae family using iminosugars, such as DNJ derivatives.
1 . A method of treating or preventing a disease or condition caused by or associated with a virus belonging to the Poxyiridae family, the method comprising administering to a subject in need thereof an effective amount of a compound of the formula,
or a pharmaceutically acceptable salt thereof,
wherein R is either selected from substituted or unsubstituted alkyl groups, substituted or unsubstituted cycloalkyl groups, substituted or unsubstituted aryl groups, or substituted or unsubstituted oxaalkyl groups; or wherein R is
R 1 is a substituted or unsubstituted alkyl group;
X 1-5 are independently selected from H, NO 2 , N 3 , or NH 2 ;
Y is absent or is a substituted or unsubstituted C 1 -alkyl group, other than carbonyl; and
Z is selected from a bond or NH; provided that when Z is a bond, Y is absent, and provided that when Z is NH, Y is a substituted or unsubstituted C 1 -alkyl group, other than carbonyl; and
wherein W 1-4 are independently selected from hydrogen, substituted or unsubstituted alkyl groups, substituted or unsubstituted haloalkyl groups, substituted or unsubstituted alkanoyl groups, substituted or unsubstituted aroyl groups, or substituted or unsubstituted haloalkanoyl groups.
2 . The method of claim 1 , wherein each of W 1 , W 2 , W 3 and W 4 is hydrogen.
3 . The method of claim 1 , wherein R is selected from substituted or unsubstituted alkyl groups, substituted or unsubstituted cycloalkyl groups, substituted or unsubstituted aryl groups, or substituted or unsubstituted oxaalkyl groups.
4 . The method of claim 1 , wherein R is C6-C12 alkyl or oxaalkyl group.
5 . The method of claim 1 , wherein R is C8-C10 alkyl or oxaalkyl group.
6 . The method of claim 1 , wherein said administering comprises administering N-nonyl deoxynojirimycin or a pharmaceutically acceptable salt thereof.
7 . The method of claim 1 , wherein said administering comprises administering N-(7-oxadecyl)deoxynojirimycin or a pharmaceutically acceptable salt thereof.
8 . The method of claim 1 , wherein said administering comprises administering N-(9-Methoxynonyl)deoxynojirimycin or a pharmaceutically acceptable salt thereof.
9 . The method of claim 1 , wherein R is
10 . The method of claim 9 , wherein X 1 is NO 2 and X 3 is N 3 .
11 . The method of claim 9 , wherein each of X 2 , X 4 and X 5 is hydrogen.
12 . The method of claim 1 , wherein said administering comprises administering is N—(N-{4′-azido-2′-nitrophenyl}-6-aminohexyl)deoxynojirimycin or a pharmaceutically acceptable salt thereof.
13 . The method of claim 1 , wherein the subject is a mammal.
14 . The method of claim 1 , wherein the subject is a human being.
15 . The method of claim 1 , wherein the virus belongs is the Orthopoxvirus family.
16 . The method of claim 15 , wherein the virus is Vaccinia virus.
17 . The method of claim 15 , wherein the virus is a cowpox virus.
18 . The method of claim 17 , wherein said administering comprises administering N-(9-Methoxynonyl)deoxynojirimycin or a pharmaceutically acceptable salt thereof.
19 . A method of infectivity of a cell infected with a virus belonging to the Poxyiridae family, the method comprising
contacting a cell infected with a virus belonging to the Poxyiridae family with an effective amount of a compound of the formula,
or a pharmaceutically acceptable salt thereof,
wherein R is either selected from substituted or unsubstituted alkyl groups, substituted or unsubstituted cycloalkyl groups, substituted or unsubstituted aryl groups, or substituted or unsubstituted oxaalkyl groups: or wherein R is
R 1 is a substituted or unsubstituted alkyl group;
X 1-5 are independently selected from H, NO 2 , N 3 , or NH 2 ;
Y is absent or is a substituted or unsubstituted C 1 -alkyl group, other than carbonyl; and
Z is selected from a bond or NH; provided that when Z is a bond, Y is absent, and provided that when Z is NH, Y is a substituted or unsubstituted C 1 -alkyl group, other than carbonyl; and
wherein W 1-4 are independently selected from hydrogen, substituted or unsubstituted alkyl groups, substituted or unsubstituted haloalkyl groups, substituted or unsubstituted alkanoyl groups, substituted or unsubstituted aroyl groups, or substituted or unsubstituted haloalkanoyl groups.
