The disclosure provides methods for inhibiting CK1 delta or CK1 epsilon activity, comprising administering an effective amount of the compound of formula I, or a pharmaceutically acceptable salt thereof. Compounds of formula I wherein Ar1 is (un)substituted aryl; X1, X2 and X3 are independently C and N; R7 is absent and CN; ring A is absent, X1:CR2 and R3X1:CR2, 4- to 7-membered cycloalkyl, heterocycloalkyl, etc.; R2 is NH2, CN, carboxy, azido, etc.; R3 is halo and CN; ring B is absent, X2CR5, R6X2CH and R6X2CR5, 4- to 7-membered cycloalkyl, etc.; R5 is CO2-C1-6 alkyl, COR10, azido, amido, etc.; R10 is 4- to 7-membered cycloalkyl, heterocycloalkyl and 5- to 6-membered heteroaryl; R6 is C1-6 alkyl, azido, amido, aryl, etc.; dashed bonds are single and double bonds; and pharmaceutically acceptable salts thereof, are claimed. Example compound II was prepared by a multistep procedure (procedure given). The invention compounds were evaluated for their casein kinase inhibitory activity. From the assay, it was determined that compound II exhibited 7.9 nM towards CK1δ. The experimental process involved the reaction of 4-Bromo-2-isopropylpyridine(cas: 908267-63-0).Product Details of 908267-63-0
