Disclosed are a novel rebamipide prodrug, a method for preparing the same, and use thereof. Also, a pharmaceutical composition comprising the novel rebamipide prodrug as an active ingredient is provided. The rebamipide prodrug is increased 25-fold in absorption rate compared to rebamipide itself, and can be applied to the prophylaxis or therapy of gastric ulcer, acute gastritis, chronic gastritis, xerophthalmia, cancer, osteoarthritis, rheumatoid arthritis, or obesity.

are defined as set forth in the specification. The invention is also directed to the use of compounds of Formula (I) to treat a disorder responsive to the blockade of sodium channels. Compounds of the present invention are especially useful for treating pain.
This invention relates to an anti-dementia agent which uses a BEC 1 potassium channel inhibitor as the active ingredient.
It was proved that the BEC 1 potassium channel inhibitor has an action to improve learning disorder and is useful as a preventive or therapeutic agent for diseases, preferably dementia, in which the BEC 1 potassium channel is considered to be concerned.
Illustratively, it was confirmed by an in vivo test that the BEC 1 potassium channel inhibitor has an action to improve learning disorder.
Also, it was found that a compound having 2,4,6-triamino-1,3,5-triazine has a BEC 1 potassium channel inhibitory action.
3-Indolepropionic acid (IPA)-related compounds having a benzo[b]thiophene or an indazole ring and derivatives having various substituents in the propionic acid moieties were tested for their antibacterial activity against Ralstonia solanacearum. Substitution of the indole ring for other aromatic rings resulted in lowered activity, whereas addition of a methyl or a trifluoromethyl group to the propionic acid moiety had little effect. Of the derivatives, 3-(3-indolyl)butanoic acid (3-IBA) was as active as IPA, exhibiting a 10-fold higher activity with the S configuration than with the R configuration. In contrast with the strong phytotoxicity of IPA, 3-IBA was able to suppress bacterial wilt without affecting the growth of tomato plants.
