Carbimazole (Athyromazole) is an Imidazolium thyroid antagonist, which is rapidly transformed into MMI in vivo and can be converted into methidazole in vitro, and can be used in the study of Graves' disease.

In vitro kinase assays: with purified proteins, recombinant S6 protein and recombinant active P70S6K are incubated in 1x kinase buffer with various amount of HCQ or RAD001 in the presence (25 μM) or absence of ATP for 30 minutes at 30°C. Total and phosphorylated S6 at ser235/236 and ser240/244 are detected by western analysis using phosphospecific antibodies. Note that recombinant GST-tagged S6 (53 kd) is distinguished from endogenous S6 (32 kd) on the western blot.
