1. A compound of the formula where R1 is H or alkyl of 1 to 6 carbons, R2 is H, alkyl of 1 to 6 carbons or the R1 and R2 groups together with the nitrogen form a saturated or unsaturated 4, 5, 6 or 7 membered ring that optionally includes one or two heteroatoms independently selected from N, O and S, said 4, 5, 6 or 7 membered ring optionally being substituted with one or two COOH, CH2OH, OH, B(OH)2, halogen groups, cyano groups, or with one or two alkyl groups having 1 to 6 carbons, or one or two carbons of said rings being attached to an oxygen to form keto groups and said 4, 5, 6 or 7 membered ring optionally being condensed with an aromatic or non-aromatic 5 or 6 membered ring that optionally includes 1 or heteroatoms selected from N, O and S;

  • R3 is independently selected from H, alkyl of 1 to 20 carbons, cycloalkyl of 3 to 6 carbons, aryl or heteroaryl, aryl-alkyl where the alkyl moiety has 1 to 4 carbons, aryl-(hydroxy)alkyl where the alkyl moiety has 1 to 4 carbons, heteroaryl-alkyl where the alkyl moiety has 1 to 4 carbons, or hetero-(hydroxy)alkyl where the alkyl moiety has 1 to 4 carbons, said aryl or heteroaryl groups being optionally substituted with 1 to 3 groups independently selected from the group consisting of halogen, alkyl of 1 to 6 carbons, alkoxy of 1 to 6 carbons and thioxy of 1 to 3 carbons, or R3 is CO—

    R7, SO2R7 or CO—

    O—

    R7 where R7 is H, alkyl of 1 to 1 to 20 carbons, alkyl of 1 to 20 carbons substituted with and NH2 group or with an NH—

    COalkyl group where the alkyl group has one to 6 carbons, aryl or heteroaryl, aryl-alkyl where the alkyl moiety has 1 to 4 carbons or heteroaryl-alkyl where the alkyl moiety has 1 to 4 carbons, said aryl or heteroaryl groups being optionally substituted with 1 to 3 groups independently selected from the group consisting of halogen, alkyl of 1 to 6 carbons, alkoxy of 1 to 6 carbons and thioxy of 1 to 3 carbons;

    R4 is H, alkyl of 1 to 6 carbons or CO—

    R8 where R8 is alkyl of 1 to 6 carbons;

    the wavy lines represent bonds connected to carbons having R or S configuration;

    the dashed lines represent a bond or absence of a bond with the proviso that the ring containing the dashed lines is aromatic;

    m, n and q are integers independently selected from 0, 1, 2 or 3 with the proviso that the sum of m, n and q is 2 or 3;

    s is zero (0) or when X is N then s is zero (0) or 1;

    W, X and Y independently represent a CH, CR5, CR6 or a heteroatom selected independently of N, O and S, and R5 and R6 are independently selected from H, halogen, alkyl of 1 to 6 carbons, halogen substituted alkyl of 1 to 6 carbons, alkoxy of 1 to 6 carbons and thioxy of 1 to 3 carbons, phenyl, or R5 and R6 together with the atoms to which they are attached jointly form a carbocyclic or a heterocyclic ring, the carbocyclic ring having 5 or 6 atoms in the ring, the heterocyclic ring having 5 or 6 atoms in the ring and 1 to 3 heteroatoms independently selected from N, O and S;

    said carbocyclic or heterocyclic ring jointly formed by R5 and R6 being optionally substituted with 1 to 6 R9 groups where R9 is independently selected from halogen, alkyl of 1 to 6 carbons, alkoxy of 1 to 6 carbons and thioxy of 1 to 3 carbons or a pharmaceutically acceptable salt of said compound with the proviso that Formula 1 does not cover compounds where R4 is H, R1 and R2 jointly with the nitrogen form a pyrrolidino or morpholino ring, the sum of m, n and q is 3, and where none of W, X and Y represent a heteroatom with the further proviso that the formula does not cover the compounds of the formula below
