Using Statistical Learning Theory to Rationalize System Model Identification and Validation Part I: Mathematical Foundations

The invention discloses novel compounds of the general formula: and salts thereof, IN WHICH THE AMINO(ALKYL) MOIETY IS PRESENT AT POSITION 2 OR 3 AND IN WHICH X stands for oxygen, sulphur, the group >NR7 or the group -CR9R9-; R1, R2, R3 and R4 represent hydrogen, hydroxy, halogen, alkyl (1-6 C), alkoxy (1-6 C), alkylthio (1-6 C) or trifluoromethyl; R5 and R6 represent hydrogen, alkyl (1-6 C), aralkyl (7-10 C) or together in combination with the nitrogen atom a heterocyclic five- or six-membered ring; R7 stands for hydrogen or alkyl (1-4 C); R8 and R9 stand for hydrogen or methyl and is the number 0, 1, 2 or 3, HAVING VALUABLE CENTRAL NERVOUS SYSTEM (CNS) activities, especially antidepressant activity.
