Compounds for the selective treatment of the intestinal immuno-inflammatory component of the celiac disease
The present invention relates to amino-salicylic-aminophenyl compounds for use in the treatment of the inflammatory component of celiac disease. These compounds act by blocking the cytokines released in celiac disease and are specifically useful in the treatment of refractory cases.
1. A method of treatment of the immune-inflammatory component of celiac disease comprising,
administering to a patient in need thereof, a therapeutically effective amount of a composition comprising a compound of formula (I) or pharmaceutically acceptable salts or esters thereof
wherein
R 1 and R 2 , equal or different from each other, are selected from the group comprising —H or a linear or branched alkyl group having 1 to 6 carbons,
Y and Z, equal or different from each other, are selected from the group comprising —H, —OH, —COOH, OR 3 , —CH(OR 3 )COOH, and
wherein R 3 is selected from H, a linear or branched alkyl group having 1 to 6 carbons, wherein administration of the composition treats the disease, and wherein said compound is selected from the group consisting of:
-(±) 3-(3′-aminophenyl)-2-hydroxy-propionic acid of formula
2-(4-aminophenyl)-2-methoxyacetic acid,
2-(3-aminophenyl)-2-ethoxyacetic acid,
2-(4-aminophenyl)-2-ethoxyacetic acid,
3-(4′-aminophenyl)-2-methoxypropionic acid of formula
3-(4′-aminophenyl)-2-ethoxypropionic acid of formula
3-(3′-aminophenyl)-2-methoxypropionic acid of formula
and
3-(3′ aminophenyl)-2-ethoxypropionic acid of formula
2. A method of treatment of the immune-inflammatory component of celiac disease comprising,
Administering to a patient in need thereof, a therapeutically effective amount of a composition comprising derivatives of 5-aminosalicylic acid selected from the group consisting of:
and their pharmaceutically acceptable salts or esters.
