    Abstract: The invention relates to 3-substituted 3,4,5,6,7,8-hexahydropyrido[3',4':4,5]thieno[2,3]pyrimidine derivatives with the formula where R1 is hydrogen, C1-C4-alkyl group, acetyl group, phenylalkyl-C1-C4-residue where the aromatic residue is optionally substituted with halogen, C1-C4-alkyl, trifluromethyl, hydroxy, C1-C4-alkoxy-, amino, cyano or nitrogroups or means phenylalkane resdue where the phenyl group can be substituted with halogen, R2 optionallly is mono- or disubstituted with halogen atoms, C1-C4-alkyl, trifluoromethyl, trifluoromethoxy, hydroxy, C1-C4-alkoxy, amino, monomethylamino, dimethylamino, cyano or nitrogroup, phenyl, pyridyl, pyrimidinyl or pyrazinyl residue which can optionally be annelated with one benzene ring which can optionally be mono- or disubstituted with halogen atoms, C1-C4-alkyl, hydroxy, trifluoromethyl, C1-C4-alkoxy, amino, cyano or nitrogroup, and optionally can contain 1 nitrogen atom or be annelated with 5- or 6-member ring which can contain from 1 to 2 oxygen atoms, A is NH or oxygen atom, Y is the group CH2, CH2-CH2, CH2-CH2-CH2 or CH2-CH, Z is nitrogen atom,carbon atom or CH where the bond bdtween Y and Z can be double, and n is the integer 2, 3 & 4. The invention also relates to physiologically acceptable salts of 3-substituted pyrido[3',4':4,5]-thieno[2,3-d]pyrimidine derivatives. The compounds show a high degree of affinity to the serotonin receptors 5-HT1B-, 5-HT1D- and 5-HT1A-. The affinity to these receptors is approximately the same or at least of the same order. Some of the compounds have good capacity for inhibiting the repeated binding of serotonin which is used in most of the antidepressants. 6 claims
