There are disclosed novel substituted and bridged pyridines having the formula
wherein:
R is hydrogen;
C1-C8 straight chain or branched alkyl; benzyl;
R1 and R4 are, e.g., hydrogen or hydrocarbon having up to 8 carbon atoms;
R2 and R3 are, e.g., hydrocarbon having up to 8 carbon atoms;
C3-Ce cycloalkyl;
C2-C8 alkyl interrupted by 1 to 2 oxygen atoms or substituted with NR5R6 wherein R5 and R6 can independently by hydrogen, C1-C8 alkyl, aralkyl wherein the alkyl groups has up to 8 carbon atoms and the aryl has 6 carbon atoms, or R5 and R6 together with the N atom can be joined to form a 5-or 6-membered ring wherein the 6-membered ring can contain an 0 or N hetereoatom and the N heteroatom can be substituted with C1-C6 alkyl;
X, W, Z and U can independently by, e.g., hydrogen;
phenyl;
halo or
NO2; provided that two of X, W, Z and U are hydrogen; or,
X and W, W and Z, or Z and U, together with the phenyl ring form naphthyl or benzooxadiazole rings;
Y is O; S; SO;
n is 0 or 1; and, the pharmaceutically acceptable acid addition salts thereof. Those compounds are useful as calcium entry blockers.
