in-house research programs. In this article, we present the discovery of clinical candidate 26a. Starting from hits plagued with poor solubility or genotoxicity, 26a was identified through thorough multiparameter optimisation. Showing robust in vivo activity in an oxazolone-mediated inflammation model, the compound was selected for development. Following a polymorph screen, the hydrochloride salt was

is a 5- to 7-membered hetero monocyclic group or a fused polycyclic group containing such a hetero monocyclic group and may have an optional substituent, but it represents a group which does not have a hydroxyl group at a position adjacent to the carbon bonded to the azo group; ring X
1
represents a monocyclic hetero ring constituted by six atoms, bonded to the azo group and may have an optional substituent; and each of R
1
and R
2
which are independent of each other, is a hydrogen atom or a monovalent substituent.
