New condensed di-hydro-pyridines

1. New condensed di-hydro-pyridines with the general formula I IMAGE> where: R1> refers to (C4-C6)-cycloalkyl, (C4-C6)-cycloalkyl-(C1-C5)-alkyl or a radical with the formula IMAGE>. R refers to (C1-C4)-alkyl, N3, a halogen, CF3 or (C1-C4)-alkoxy, u is equal to 1, 2 or 3, R3> and R4> refer independently to hydrogen or a branching or non-branching alkyl with 1 to 12 atoms of carbon, while R3> and R4> do not refer simultaneously to hydrogen, and the alkyl may be substituted with cyclohexyl or phenyl, while the phenyl may be substituted once, twice or three times with (C1-C4)-alkoxy, a halogen, (C1-C4)-alkyl, or trifluoromethyl, or its salts with physiologically-tolerated acids/bases.
