FIELD OF THE INVENTION The present invention relates to (IA) generic pyran [3,2-c] pyridine derivatives (IB), quaternary derivatives of the general formula (IB) and unsaturated derivatives of the general formula (IC) and salts thereof, pharmaceutical compositions containing azes, and a process for the preparation of vines and applications. . In the general formulas, n is 3, 4 or 5; A is an inorganic or organic acid anion; R1 is a tubular member of the general formula (A), (B) or (C); R 3 is a hydrogen atom, substituted aralkylcyrofoam or acyl tube; R6 is an amine ring, -CH2COR or -N = CH-NRIVRV; R is an alkyloxyl radical, in the case of a substituted aryl tube coat, or in the case of a substituted amine powder; R 'and R' 'are independently hydrogen, substituted alkyl, cycloalkyl, aralkyl or aryl; R '' represents an acyl tube or substituted carbamoy tube; RIV and RV are independently hydrogen, alkyl, aryl, or aralkyl, or -NRIVRV together form a 5-7 membered, nitrogen-containing heterocycle; in addition, when in the general formula (IA), R1 is a (A) general moiety, it has a meaning other than that of R3. The compounds of the present invention have antihypertensive activity. ŕ |
