Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
53 words
A method for prophylaxis or therapeutic treatment of retrovirus infections of mammals which comprises administering to a mammal requiring said prophylaxis or treatment a polymeric carbohydrate containing sulfate groups but no carboxyl (--COOH) or amino (--NH 2 ) groups in an amount sufficient to provide efficient prophylactic or therapeutic effects against retrovirus infections.
Claim 2
Independent Claim
53 words
A method for prophylaxis or therapeutic treatment of retrovirus infections of mammals which comprises administering to a mammal requiring said prophylaxis or treatment a polymeric carbohydrate containing sulfate groups but no carboxyl (--COOH) or amino (--NH 2 ) groups in an amount sufficient to provide efficient prophylactic or therapeutic effects against retrovirus infections.
Claim 3
Dependent Claim
15 words
The method according to claim 1, wherein the polymeric carbohydrate is composed of monomeric pentoses.
Claim 4
Dependent Claim
15 words
The method according to claim 1, wherein the polymeric carbohydrate is composed of monomeric hexoses.
Claim 5
Dependent Claim
23 words
The method according to claim 2 or 3, wherein the polymeric carbohydrate is composed of pyranose units having 5 or 6 carbon atoms.
Claim 6
Dependent Claim
13 words
The method according to claim 4, wherein the pyranose units are xylopyranose groups.
Claim 7
Dependent Claim
13 words
The method according to claim 4, wherein the pyranose units are glucopyranose groups.
Claim 8
Dependent Claim
14 words
The method according to claim 5, wherein the polymeric carbohydrate is a pentosane polysulfate.
Claim 9
Dependent Claim
15 words
The method according to claim 7, wherein the polymeric carbohydrate is pentosane polysulfate MW 5,000.
Claim 10
Dependent Claim
22 words
The method according to claim 6, wherein the polymeric carbohydrate is a dextran sulfate with a molecular weight of at least 6,000.
Claim 11
Dependent Claim
15 words
The method according to claim 9, wherein the polymeric carbohydrate is dextran sulfate MW 8,000.
