Abstract: A method for therapeutically treating an animal, including a human, for psychosomatic, depressive and neuropsychiatric diseases, such as anxiety, depression, insomnia, schizophrenia, epilepsy, spasm and chronic pain. Administration of a suitable DP IV inhibitor causes the reduction of activity in the enzyme dipeptidyl peptidase (DP IV or CD 26) or of DP IV-like enzyme activity in the brain of mammals and leads as a causal consequence to a reduced degradation of the neuropeptide Y (NPY) and similar substrates by DP IV and DP IV-like enzymes. Such treatment will result in a reduction or delay in the decrease of the concentration of functionally active neuronal NPY (1-36). As a consequence of the resulting enhanced stability of the endogenous NPY (1-36) caused by the inhibition of DP IV activity, NPY activity is prolonged thereby resulting among other things in functionally active NPY Y1 receptor activity thereby facilitating antidepressive, anxiolytic, analgesic, antihypertension and other neurological effects.

Abstract: The present invention discloses a method for therapeutically treating an animal, including a human, for psychosomatic, depressive and neuropsychiatric diseases, such as anxiety, depression, insomnia, schizophrenia, epilepsy, spasm and chronic pain. Administration of a suitable DP IV inhibitor causes the reduction of activity in the enzyme dipeptidyl peptidase (DP IV or CD 26) or of DP IV—like enzyme activity in the brain of mammals and leads as a causal consequence to a reduced degradation of the neuropeptide Y (NPY) and similar substrates by DP IV and DP IV-like enzymes. Such treatment will result in a reduction or delay in the decrease of the concentration of functionally active neuronal NPY (1-36).

Abstract: Dipeptide compounds and compounds analogous to dipeptide compounds that are formed from an amino acid and a thiazolidine or pyrrolidine group, and salts thereof used in the treatment of impaired glucose tolerance, glycosuria, hyperlipidaemia, metabolic acidoses, diabetes mellitus, diabetic neuropathy and nephropathy and also of sequelae of diabetes mellitus in mammals.

Abstract: The invention relates to a simple and industrially readily executable method of producing thiazolidine base and salts thereof. In particular, the invention relates to a process for the production of thiazolidine base and salts thereof which is characterized in that hexamethylenetetramine of formula (I) is caused to react with cysteamine or salts thereof of formula (II) in which X(−) represents an acid residue, X(−) being preferably a halide or sulfate.
