Guiding farnesyltransferase inhibitors from an ECLiPS library to the catalytic zinc

Bioorg Med Chem Lett. 2006 Feb;16(3):507-11. doi: 10.1016/j.bmcl.2005.10.070. Epub 2005 Nov 10.

Abstract

Farnesyltransferase inhibitors identified from an ECLiPS library were optimized using solution-phase synthesis. X-ray crystallography of inhibited complexes was used to identify substructures that coordinate to the active site zinc. The X-ray structures were ultimately used to guide the design of second-generation analogs with FTase IC(50)s of less than 1.0 nM.
