Abstract
Abstract Dextransucrase synthesis of dextran from sucrose is inhibited by substituted sucrose compounds which have an inhibiting group bonded to the 5-position ring carbon. Oral compositions containing such substituted sucrose compounds can be used to control dextran formation in the mouth, and dextran comprises the principal component of dental plaque.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
78 words
The method of inhibiting dextransucrase synthesis of dextran from sucrose, comprising introducing into an aqueous substrate containing sucrose and dextransucrase an inhibitory amount of a substituted sucrose compound, said substituted sucrose compound having bonded to the 5-position ring carbon a group selected from the class consisting of --CH 2 X, ═CH 2 , --CHO, and --H, wherein X is selected from the class consisting of --Br, --I, --N 3 , --NH 2 , --OCH 3 , and --H.
Claim 2
Independent Claim
78 words
The method of inhibiting dextransucrase synthesis of dextran from sucrose, comprising introducing into an aqueous substrate containing sucrose and dextransucrase an inhibitory amount of a substituted sucrose compound, said substituted sucrose compound having bonded to the 5-position ring carbon a group selected from the class consisting of --CH 2 X, ═CH 2 , --CHO, and --H, wherein X is selected from the class consisting of --Br, --I, --N 3 , --NH 2 , --OCH 3 , and --H.
Claim 3
Dependent Claim
19 words
The method of claim 1 in which said group bonded to the 5-position ring carbon is --CH 2 I.
Claim 4
Dependent Claim
19 words
The method of claim 1 in which said group bonded on the 5-position ring carbon is --CH 2 Br.
Claim 5
Dependent Claim
28 words
The methods of claim 1 in which said substituted sucrose also has bonded to the 5'-position ring carbon the same group as bonded to the 5-position ring carbon.
Claim 6
Dependent Claim
20 words
The method of claim 1 in which said substituted sucrose is selected from the class consisting of 6,6'-dideoxy-6,6'-dibromosucrose, and 6,6'-dideoxy-6,6'-diiodosucrose.
Claim 7
Dependent Claim
79 words
An oral composition comprising a carrier suitable for use in the oral cavity containing an amount of a substituted sucrose compound effective for inhibiting the dextransucrase synthesis of dextran, said substituted sucrose compound having bonded to the 5-position ring carbon a group selected from the class consisting of --CH 2 X, ═CH 2 , --CHO, and --H, wherein X is selected from the class consisting of --Br, --I, --N 3 , --NH 2 , --OCH 3 , and --H.
Claim 8
Dependent Claim
79 words
An oral composition comprising a carrier suitable for use in the oral cavity containing an amount of a substituted sucrose compound effective for inhibiting the dextransucrase synthesis of dextran, said substituted sucrose compound having bonded to the 5-position ring carbon a group selected from the class consisting of --CH 2 X, ═CH 2 , --CHO, and --H, wherein X is selected from the class consisting of --Br, --I, --N 3 , --NH 2 , --OCH 3 , and --H.
Claim 9
Dependent Claim

Claim 10
Dependent Claim
20 words
The oral composition of claim 6 in which said group bonded to the 5-position ring carbon is --CH 2 Br.
Claim 11
Dependent Claim
29 words
The oral composition of claim 5 in which said substituted sucrose also has bonded to the 5'-position ring carbon the same group as bonded to the 5-position ring carbon.
Claim 12
Dependent Claim
21 words

Claim 13
Dependent Claim
18 words
The oral composition of claims 6, 7, 8, 9 or 10 in which said carrier is a toothpaste.
Claim 14
Dependent Claim
18 words
