Abstract
Abstract A use in human therapy (viz as an active ingredient for inhibiting tooth decay, for reducing acidogenesis by mouth flora, and for reducing adhesion to dental surfaces of mouth flora and reducing plaque formation on dental surfaces) has been found for chlorodeoxysucrose derivatives of the general formula ##STR1## (wherein: R 4 α is a hydroxy group and R 4 β is a hydrogen atom, or, one of R 4 α and R 4 β is a hydrogen atom and the other is a chlorine atom; R 6 is a hydroxy group or, if at least one of R 4 α, R 4 β or R 1 is a chlorine atom, then it is a hydroxy group or a chlorine atom; R 1' is a hydroxy group or a chlorine atom; and R 6' is a hydroxy group, or if at least one of R 4 α, R 4 β or R 1 is a chlorine atom, then it is a hydroxy group or a chlorine atom).

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
143 words
A method of preventing or limiting dental caries by administering to the subject an anticariogenic-effective amount of a chlorodeoxysucrose derivative of the general formula ##STR4## wherein: R 4 α is a hydroxy group and R 4 β is a hydrogen atom, or, one of R 4 α and R 4 β is a hydrogen atom and the other is a chlorine atom; R 6 is a hydroxy group or, if at least one of R 4 α, R 4 β or R 1' is a chlorine atom, then it is a hydroxy group or a chlorine atom; R 1' is a hydroxy group or a chlorine atom; and R 6' is a hydroxy group, or if at least one of R 4 α, R 4 β or R 1' is a chlorine atom, then it is a hydroxy group or a chlorine atom.
Claim 2
Independent Claim
143 words
A method of preventing or limiting dental caries by administering to the subject an anticariogenic-effective amount of a chlorodeoxysucrose derivative of the general formula ##STR4## wherein: R 4 α is a hydroxy group and R 4 β is a hydrogen atom, or, one of R 4 α and R 4 β is a hydrogen atom and the other is a chlorine atom; R 6 is a hydroxy group or, if at least one of R 4 α, R 4 β or R 1' is a chlorine atom, then it is a hydroxy group or a chlorine atom; R 1' is a hydroxy group or a chlorine atom; and R 6' is a hydroxy group, or if at least one of R 4 α, R 4 β or R 1' is a chlorine atom, then it is a hydroxy group or a chlorine atom.
Claim 3
Dependent Claim
35 words
A method of reducing acidogenesis by mouth flora in the presence of a carbohydrate, comprising contacting the flora in the mouth with a chlorodeoxysucrose derivative of the general formula (II) as defined in claim 1.
Claim 4
Dependent Claim
38 words
A method of reducing the adhesion of cells of mouth flora to dental surfaces and of reducing plaque formation thereon, comprising contacting the teeth with a chlorodeoxysucrose derivative of the general formula (II) as defined in claim 1.
Claim 5
Dependent Claim
14 words
The method of claim 1, 2 or 3, wherein the chlorodeoxysucrose derivative is 4,1',6'-trichloro-4,1',6'-trideoxygalactosucrose.
Claim 6
Dependent Claim
16 words
The method of claim 1, 2 or 3, wherein the chlorodeoxysucrose derivative is 1'-chloro-1'-deoxysucrose or 6,1',6'-trichloro-6,1',6'-trideoxysucrose.
Claim 7
Dependent Claim
34 words
The method of claim 1, 2 or 3, wherein the amount of the chlorodeoxysucrose derivative is less than 15.(x) -1 weight percent where x is the sweetening power relative to a 10% sucrose solution.
Claim 8
Dependent Claim
16 words
The method of claim 1, 2 or 3, wherein the chlorosucrose derivative is 1',6'-dichloro-1',6'-dideoxysucrose or 4-chloro-4-deoxy-α-D-galactopyranosyl-1-chloro-1-deoxy-β-D-fructofuranoside.
Claim 9
Dependent Claim
25 words
The method of claim 1 wherein said derivative is administered in the form of a dental composition containing less than 0.1 wt.% of said derivative.
