Abstact

We describe two series of Syk inhibitors which potently abrogate Syk kinase function in enzymatic assays, cellular assays and in primary cells in the presence of blood. Introduction of a 7-aminoindole substituent led to derivatives with good kinase selectivity and little or no hERG channel inhibition (3b, 10c).
