Citation | Journal: IUCrJ / Year: 2026Title: Cryo-EM-guided subtractive optimization of a novel VCP/p97 inhibitor. Authors: Jason Crawford / Ravi Munuganti / Charles Leung / Kriti Singh / Ellen Gates / Xing Zhu / Marcel Bally / Nancy Dos Santos / Maryam Sharifiaghdam / Zeynab Nosrati / Peter Axerio-Cilies / ...Authors: Jason Crawford / Ravi Munuganti / Charles Leung / Kriti Singh / Ellen Gates / Xing Zhu / Marcel Bally / Nancy Dos Santos / Maryam Sharifiaghdam / Zeynab Nosrati / Peter Axerio-Cilies / Alison M Berezuk / Spencer Cholak / Alan Merk / Dale R Cameron / Sriram Subramaniam / ![]() Abstract: We report the cryo-EM structure-guided discovery of GND-135, a novel small-molecule inhibitor of the VCP/p97 AAA ATPase that demonstrates efficient inhibition of VCP/p97 in biochemical, cellular, and ...We report the cryo-EM structure-guided discovery of GND-135, a novel small-molecule inhibitor of the VCP/p97 AAA ATPase that demonstrates efficient inhibition of VCP/p97 in biochemical, cellular, and pharmacokinetic assays and in a tumor efficacy mouse model of acute myeloid leukemia. Our approach overcomes the liability in the clinical-stage compound CB-5083 where Phase I studies showed off-target activity of CB-5083 for the enzyme PDE6. From the cryo-EM structural analysis of CB-5083 bound to PDE6 and VCP/p97, we identified critical ligand/protein interactions in both proteins and rationally designed a small molecule that retains key interactions necessary for VCP/p97 inhibition while eliminating PDE6 off-target activity. We refer to this approach as `subtractive optimization' because we are leveraging our ability to determine both on-target and off-target cryo-EM structures to guide the medicinal chemistry campaign to enable more targeted compound design. While this strategy is not possible in all cases, the use of cryo-EM to tune on-site binding while eliminating off-target binding could be a generally applicable strategy for informing molecular design and accelerating small-molecule drug discovery. #1: Journal: Acta Crystallogr D Struct Biol / Year: 2019 Title: Macromolecular structure determination using X-rays, neutrons and electrons: recent developments in Phenix.

The overall structure-solution workflow is similar for these techniques, but nuances exist because the properties of the reduced experimental data are different. Software tools for structure determination should therefore be tailored for each method. Phenix is a comprehensive software package for macromolecular structure determination that handles data from any of these techniques. Tasks performed with Phenix include data-quality assessment, map improvement, model building, the validation/rebuilding/refinement cycle and deposition. Each tool caters to the type of experimental data. The design of Phenix emphasizes the automation of procedures, where possible, to minimize repetitive and time-consuming manual tasks, while default parameters are chosen to encourage best practice. A graphical user interface provides access to many command-line features of Phenix and streamlines the transition between programs, project tracking and re-running of previous tasks. | ||||||||||||||||||||||||
