Abstract

Referido a un compuesto que tiene la estructura de la Formula I, o una sal, solvato, estereoisomero, variante isotopica, o N-oxido farmaceuticamente aceptables de este, en donde R1 es H, halo, o CH3; Ar1 se selecciona del grupo que consiste en: (a) fenilo sustituido con un miembro seleccionado del grupo que consiste en: halo, alquilo C1-6, entre otros; (b) fenilo sustituido con dos o tres miembros cada uno independientemente seleccionado del grupo que consiste en: halo, alquilo C1-6, perhaloalquilo C1-6, entre otros; (c) tienilo sustituido con un miembro seleccionado del grupo que consiste en: halo, alquilo C1-6, y perhaloalquilo C1-6, entre otros. Un compuesto seleccionado es 1-(pirimidin-2-ilmetil)-6-[3-(trifluorometil)fenil]pirazolo[4,3-b]piridina. Estos compuestos pirazolo piridinas heteroaromaticas sustituida son moduladores del receptor GLUN2B. Tambien se refiere procesos para preparar estos compuestos, compuestos intermedios, a una composicion farmaceutica que comprende dicho compuesto, y su uso en el tratamiento de enfermedad mediada por el receptor GluN2B tales como: trastorno bipolar, trastorno depresivo mayor, depresion resistente al tratamiento, entre otros.
