The invention concerns pharmaceutically useful peptide derivatives of the formula (I): P--R.sup.1 --R.sup.2 --R.sup.3 --R.sup.4, in which P, R.sup.1, R.sup.2, R.sup.3, and R.sup.4 have the various meanings defined herein, and their pharmaceutically acceptable salts, and pharmaceutical compositions containing them. The novel peptide derivatives are of value in treating MHC class II dependent T-cell mediated autoimmune or inflammatory diseases, such as rheumatoid arthritis. The invention further concerns processes for the manufacture of the novel peptide derivatives and the use of the compounds in medical treatment.
The present invention provides a method for promoting plant growth, which comprises treating a plant with at least one compound selected from a group consisting of a compound represented by the following Formula (1):
and an agriculturally acceptable salt thereof, provided that a method for promoting plant growth which comprises treating plants with a compound corresponding to any one of the following (1) to (5) and an agriculturally acceptable salt thereof is excluded: (1) 4-(Trifluoromethyl)benzo[b]thiophene-2-carboxylic acid, (2) 5-(Trifluoromethyl)benzo[b]thiophene-2-carboxylic acid, (3) 6-(Trifluoromethyl)benzo[b]thiophene-2-carboxylic acid, (4) 7-(Trifluoromethyl)benzo[b]thiophene-2-carboxylic acid, and (5) Benzo[b]thiophene-2-carboxylic acid.
