Patent ID: 7157078

Claim:
A cellulase inhibitor, comprising in combination: a) a compound of formula wherein R 1 is selected from the group consisting of a bond, a hydrocarbon group, O, and NR 14 R 15 , wherein R 14 and R 15 are each independently selected from the group consisting of a hydrogen atom and a hydrocarbon group; each R 2 is independently selected from the group consisting of CH, a carbon atom, and a heteroatom; R 3 , R 4 , R 5 , and R 6 are each independently selected from the group consisting of hydrogen atoms, hydroxyl groups and methyl groups, and R 7 and R 8 are each independently selected from the group consisting of hydrogen atoms, oxygen atoms, nitrogen atoms, hydroxyl groups and NH 2 groups, wherein (i) when R 7 is II, OH or NH 2 , R 9 is absent; and (ii) when R 8 is II, OH or NH 2 , R 10 is absent; R 9 and R 10 are each independently selected from the group consisting of hydrocarbon groups of 1 to 6 carbon atoms, alkyl esters of 1 to 6 carbon atoms, and amides; and R 11 and R 12 are each independently selected from the group consisting of saturated, unsaturated, and aromatic groups, b) a cellulose containing material, and c) water, wherein said cellulase inhibitor inhibits β-glucosidase, endoglucanase, exoglucanase or combinations thereof.
