Fig. 1. BPH-1222 and zoledronate bind to the same site of FPPS.
(A) Zoledronate. (B) A library of zoledronate analogs, side-chain length n= 0–15, X= H or OH. (C) BPH-1222. (D) Structure of BPH-1222 binding to FPPS was determined by single crystal X-ray crystallography. Zoledronate binding is shown superimposed with BPH-1222 (zoledronate in yellow and BPH-1222 in cyan).
