Abstract: A method of treating inner ear hardness of hearing and restoring hearing of humans and animals after damage and loss of sensory hair cells in an organ of Corti based on regeneration biology includes administering a therapeutically effective amount of a compound including aminoalkyloxazole and aminoalkylthiazole carboxylic acid amides, or a pharmaceutically acceptable salt, a stereoisomer, a stereoisomer mixture, a tautomer or a prodrug compound thereof, directly or indirectly to damaged tissue structures in a cochlea, optionally, by transtympanal injection into a middle ear, by application to a round or oval window of an inner ear or by injection into the inner ear.

Abstract: Aminoalkyloxazole and aminoalkylthiazolecarboxylic acid amides of formulae (1) and (2) where X represents O or S, Y represents C or N, where the two atoms must be different from one another, R2 represents hydrogen or acyl and R1 and R3, which may be identical or different, represent a substituent selected from the group consisting of branched or straight-chain, substituted or unsubstituted alkyl groups, alkylcycloalkyl groups, alkylaryl groups, cycloalkyl groups, cycloalkylaryl groups, aryl groups and arylcycloalkyl groups which optionally contain heteroatoms, a pharmaceutically acceptable salt, a stereoisomer, a stereoisomer mixture, a tautomer or a prodrug compound, preferably a prodrug ester and a prodrug peptide, thereof.
