Expediting FEP+ model optimization for challenging systems with a fully automated, machine learning-driven workflow

Expediting FEP+ model optimization for challenging systems with a fully automated, machine learning-driven workflow

FEP+ is a powerful predictive technology in drug discovery – with applications from hit discovery through lead optimization. A critical first step in deploying FEP+ is to validate and optimize the model for the protein-ligand system of interest. While some systems perform well with out-of-the-box FEP+ settings, others require manual protocol refinement.

In this webinar, we will introduce Schrödinger’s FEP+ Protocol Builder, an automated machine learning workflow for FEP+ model optimization. This workflow is designed for systems with insufficient predictive accuracy using default settings or after initial manual protocol optimization attempts. FEP+ Protocol Builder saves researcher time and increases the chances of successfully enabling FEP+ by efficiently identifying an optimized predictive model for your system of interest.

Join us as we share key features of FEP+ Protocol Builder and highlight case studies that have shown success utilizing the technology to accelerate projects.

Highlights:

  • Overview of FEP+ Protocol Builder technology, which uses an Active Learning workflow to iteratively search the protocol parameter space to develop accurate FEP+ protocols
  • Case studies on effective prospective use of protocols generated by FEP+ Protocol Builder in drug discovery programs
  • Comparison of time efficiency between manual and automated FEP+ optimization
  • Details on requirements and services options to leverage the technology in your own program
  • Overview of the different options to enable FEP+ at almost all levels of structural information for your protein-ligand system of interest

Impacting Drug Discovery Programs with Large-Scale De Novo Design

JAN 25, 2024

Impacting Drug Discovery Programs with Large-Scale De Novo Design

Developing technologies to more comprehensively and effectively enable de novo design of high-quality chemical matter has been a long-standing goal of drug discovery.

To this end, Schrödinger has recently spearheaded the development of workflows that combine large-scale synthetically-aware de novo design methods (AutoDesigner) with rigorous free energy-based scoring methods (Active Learning FEP+) for potency and selectivity optimization of small molecules. Recent developments of this technology move beyond R-group design to core exploration, enabling its expanded application to early stage hit identification efforts and the discovery of back-up series.

In this webinar, we will describe several recent case studies from Schrödinger’s therapeutics group where these de novo design technologies have allowed teams to overcome critical design challenges and accelerate programs.

Highlights

  • Real-life comparison of AutoDesigner versus other common design methods, including an evaluation of chemical space explored, time spent, and ability to meet design goals
  • Design of novel cores during hit identification using AutoDesigner
  • Design of R-groups during hit-to-lead and lead optimization using AutoDesigner
  • Examples of improving potency and selectivity of a molecular glue and using de novo design to strengthen IP
  • Requirements and best practices to apply the technology to your drug discovery programs

LiveDesign

What’s New in 2023-1

  • Project Overview Landing Page: View summarized landing page information
  • Vertical only Kanban: Create a Kanban view using a single picklist Freeform column
  • Forms
    • Use keyboard controls with the Compound Image widget to navigate from one compound to another
    • Define independent column widths for each widget
  • Generic Entity: Store Lot and Experimental data on any chemical, biological, or material matter with any representation
  • New enhancements to existing features, such as:
    • View the regression equation on scatter plots
    • Admins can log out users by removing their assigned Roles, or by specifying a specific username
    • Removing a single enhanced stereochemical AND group with the structure processor now defines the stereocenter as ‘undefined’, and previously would define is as an absolute stereocenter
    • Use advanced atom query features in substructure filtering
  • Performance Improvements
    • SAR analysis tasks are performed asynchronously and take less time to complete
    • The 3D visualizer is more responsive when large proteins are viewed

What’s Been Fixed

  • Models that returned a single value now show the full result unaligned with other columns
  • The 3D visualizer uses the high performance GPU on client computers to avoid crashes
  • Pasting multiple values into ID search will attempt to automatically identify the delimiter, or present an option to select the delimiter, by which to separate values
  • Limited Assay Columns are now included in Matched Molecular Pairs analyses
  • Pasting multiple values into Filters will attempt to automatically identify the delimiter, or present an option to select the delimiter, by which to separate values
  • File import receipts show a scroll bar for errors parsing SD files
  • Pinned plot tooltips in forms update the connecting line when the view is resized
  • The file import receipt now shows IDs from SD file title lines
  • Overlay lines in plots will now extend to the full plot dimensions
  • Automatically generated coloring rules for R-groups, Scaffolds, and String columns that were created through the plot interface will now appear in plots
  • Pinned tooltips now point to the correct data points in box plots
  • The radar chart legend now shows which compound IDs are out of range by hovering over the “Out of Range” entry in the plot legend
  • Multi-parameter optimization column dialogs appeared to allow unauthorized users to edit the definition, however any edits submitted were not saved. The dialog now shows all fields as disabled to unauthorized users.
  • LiveReports set to Read-Only no longer allow users to configure Tile View
  • Line charts no longer show R-groups as SMILES strings in the plot legend, and instead show images
  • Forms with many narrow widgets not longer show errors when editing the Form
  • Dragging to select multiple histogram bars will select all of the compounds within the bin
