A compound having the structure of Formula: or a pharmaceutically acceptable salt thereof, wherein: X and Y are independently selected from the group consisting of CH and N, with the proviso that when X is CH, Y is N, and when X is N, Y is CH; R 1 is selected from the group consisting of C 1 -C 6 -alkyl, halo and -H; R 2 is selected from the group consisting of alkyl and alkoxy; wherein the alkyl or alkoxy is optionally substituted with one or more substituents independently selected from heterocyclyl; and wherein the heterocyclyl is optionally substituted with one or more substituents independently selected from the group consisting of alkyl, alkoxy and cyano; R 3 and R 4 are independently selected from the group consisting of alkyl, halo and-H; and R 5 is selected from the group consisting of cycloalkyl and heteroaryl; wherein cycloalkyl means a hydrocarbyl group containing at least one saturated or partially unsaturated ring structure and attached via a ring carbon, and heteroaryl means a monocyclic, bicyclic or tricyclic ring having up to 6 atoms in each ring wherein at least one ring is aromatic and contains from 1 to 4 heteroatoms in the ring selected from the group consisting of N, O and S, "heteroaryl" including the N-oxide derivative of any nitrogen containing heteroaryl; wherein the cycloalkyl is optionally substituted with one or more substituents independently selected from the group consisting of halo, cyano, alkyl, hydroxyalkyl, alkoxyalkyl and aminoalkyl; and wherein the heteroaryl is substituted with one or more substituents independently selected from the group consisting of cyano, alkyl, hydroxyalkyl, alkoxyalkyl and aminoalkyl. X and Y are independently selected from the group consisting of CH and N, with the proviso that when X is CH, Y is N, and when X is N, Y is CH; R 1 is selected from the group consisting of C 1 -C 6 -alkyl, halo and -H; R 2 is selected from the group consisting of alkyl and alkoxy; wherein the alkyl or alkoxy is optionally substituted with one or more substituents independently selected from heterocyclyl; and wherein the heterocyclyl is optionally substituted with one or more substituents independently selected from the group consisting of alkyl, alkoxy and cyano; R 3 and R 4 are independently selected from the group consisting of alkyl, halo and-H; and R 5 is selected from the group consisting of cycloalkyl and heteroaryl; wherein cycloalkyl means a hydrocarbyl group containing at least one saturated or partially unsaturated ring structure and attached via a ring carbon, and heteroaryl means a monocyclic, bicyclic or tricyclic ring having up to 6 atoms in each ring wherein at least one ring is aromatic and contains from 1 to 4 heteroatoms in the ring selected from the group consisting of N, O and S, "heteroaryl" including the N-oxide derivative of any nitrogen containing heteroaryl; wherein the cycloalkyl is optionally substituted with one or more substituents independently selected from the group consisting of halo, cyano, alkyl, hydroxyalkyl, alkoxyalkyl and aminoalkyl; and wherein the heteroaryl is substituted with one or more substituents independently selected from the group consisting of cyano, alkyl, hydroxyalkyl, alkoxyalkyl and aminoalkyl.
