The invention relates to chemical compounds of the formula (I) or pharmaceutically acceptable salts thereof, which possess B-Raf inhibitory activity and are accordingly useful for their anti cancer activity and thus in methods of treatment of the human or animal body. The invention also relates to processes for the manufacture of said chemical compounds, to pharmaceutical compositions containing them and to their use in the manufacture of medicaments of use in the production of an anti-cancer effect in a warm blooded animal such as man.
possessing biphenyltetrazole was discovered to be potent human ChemR23 inhibitors. We initially tried to improve the potency of compound 1, which was found through in-house screening using the human plasmacytoid dendritic cell (pDC)-like cell line CAL-1. The introduction of a chiralmethyl moiety at a benzylic position in a center of compound 1 showed a large impact on the inhibitory activity against calcium
