Zuercher TI - Development of Narrow Spectrum ATP-competitive Kinase Inhibitors as Probes for BIKE and AAK1 AID - 10.1101/094631 DP - 2017 Jan 01 TA - bioRxiv PG - 094631 4099 - http://biorxiv.org/content/early/2017/03/02/094631.short 4100 - http://biorxiv.org/content/early/2017/03/02/094631.full AB - Understanding the structural determinants of inhibitor selectivity would facilitate the design and preparation of kinase probes. We describe a pair of matched compounds differing only by one degree of saturation but showing dramatic differential activities at select kinases. We utilized x-ray crystallography and computational analysis to rationalize the basis of the differential activity.
