Fluorescence was recorded for 15 min (0.7 s per well, 20 repeats) at 30 °C with an excitation filter at 340 nm and an emission filter of 486 nm. Each measurement was reproduced in duplicate. The kinetic experiments were realized under the same conditions, either with FPP as varied substrate with a constant concentration of Dns-GCVLS of 2.5 μM, or with Dns-GCVLS as varied substrate with a constant concentration of FPP of 10 μM. Non linear regressions were performed with KaleidaGraph 4.03 software. Coudray, L.; de Figueiredo, R. M.; Duez, S.; Cortial, S.; Dubois, J. J. Enz. Inh. Med. Chem. 2009, 24, 972.

    • Molecular modelling: Based on previous studies, 1LD7 (Bell, I. M.; Gallicchio, S. N.; Abrams, M.; Beese, L. S.; Beshore, D. C.; Bhimnathwala, H.; Bogusky, M. J.; Buser, C. A.; Culberson, J. C.; Davide, J.; Ellis-Hutchings, M.; Fernandes, C.; Gibbs, J. B.; Graham, S. L.; Hamilton, K. A.; Hartman, G. D.; Heimbrook, D. C.; Homnick, C. F.; Huber, H. E.; Huff, J. R.; Kassahun, K.; Koblan, K.

The reference ligand and water molecules were removed, then the cocrystallized inhibitor was repositioned into the binding site defined as a 10 Å sphere around its position in the crystal, needing a distance constraint to maintain proximity to the zinc. This constraint was later withdrawn as metal atoms were directly taken into account by newer versions docking software and the studied compounds became more remote from the cocrystallized inhibitor. The protonation state of the protein and ligands was found to be compatible with a pH of 7.5 and the geometry of the ligands optimized using Gasteiger-Hückel partial charges, with a formal charge of +2 applied to iron atoms and a dielectric constant set to 4. After applying a formal charge of +2 on the farnesyltransferase zinc, metal atoms were handled by GOLD with the default geometry corresponding to their coordination. The 30 docking solutions were ranked based on a consensus scoring by GoldScore and X Score, then, visually inspected to assess the consistency of the best ranking conformation and select the most inhibitory clusters or conformation, when several were found.
