Discovery of the S1P2 Antagonist GLPG2938 (1-[2-Ethoxy-6-(trifluoromethyl)-4-pyridyl]-3-[[5-methyl-6-[1-methyl-3-(trifluoromethyl)pyrazol-4-yl]pyridazin-3-yl]methyl]urea), a Preclinical Candidate for the Treatment of Idiopathic Pulmonary Fibrosis
that blocking S1P2 receptor (S1PR2) signaling could be effective for the treatment of idiopathicpulmonaryfibrosis (IPF). However, only a few antagonists have been so far disclosed. A chemical enablement strategy led to the discovery of a pyridine series with good antagonist activity. A pyridazine series with improved lipophilic efficiency and with no CYP inhibition liability was identified by scaffold
Compounds for the inhibition of mammalian Ste20-like kinase 1 (MST1) are disclosed, along with compositions comprising them and methods of their use in the treatment, management or prevention of an inflammatory or autoimmune diseases or disorders. Particular compounds are of the formula:
