Pairing machine learning and FEP+ enables the discovery of P38-MK2 molecular glues

Speaker:
Gang Wang, Principal Scientist II, Schrödinger

Abstract:
Mitogen activating protein kinases (MAPK)-activated kinase MK2 phosphorylates AU-rich element binding proteins (AUBPs) that modulate the stability of cytokine mRNA. An emerging class of inhibitors create a ternary complex with upstream kinase p38 and MK2. These molecular glues demonstrate superior properties relative to orthosteric inhibitors of either p38 or MK2 but their mechanism of action presents challenges to computationally driven design. Herein we describe our computational design strategy, including the use of FEP+ coupled with Machine Learning (e.g., AutoDesigner and AL-FEP+), to discover multiple structurally diverse, potent, and highly selective molecular glues. Compounds 1 and 2 demonstrate pronounced reduction in TNFα levels after PO dosing in LPS mouse models and represent the validation of our modeling workflow for challenging molecular glues.

Poster: Materials innovation for advanced electronic packaging using digital chemistry

Speaker:
Atif Afzal, Principal Scientist II, Schrödinger

Abstract:
The push for ever-improving characteristics of electronic devices demands packaging materials with superior thermal stability, mechanical strength, water repellency, and interfacial properties. Traditional material selection methods, often reliant on extensive empirical testing, are time-consuming and costly, limiting the ability for researchers to push beyond what they already know. To address these challenges, we propose a new approach that integrates physics-based modeling with machine learning (ML) to accurately model and predict the properties of advanced materials for electronic packaging. Our physics-based modeling, molecular dynamics (MD) simulations, offer detailed atomistic insights into material behavior under various conditions, providing essential data on thermal properties, mechanical resilience, adhesion, and more. To accelerate the material evaluation process and to navigate new chemical domains more efficiently, we integrate ML in our workflows. By training ML models using both experiment and simulation data, we can rapidly predict the properties of new materials, enabling efficient screening and selection. We demonstrate the efficacy of this approach through a case study focused on designing copolymers with targeted properties. Our integrated MD-ML framework allows us to quickly identify polymers that meet specific performance criteria, such as enhanced glass transition and superior dielectric properties, while significantly reducing the time and resources required for material discovery. This work highlights the transformative potential of combining physics-based simulations with machine learning in the field of electronic packaging. By streamlining the material development process, our approach not only accelerates innovation but also enables the creation of materials that meet the stringent demands of next-generation electronic devices.

Talk: Material property simulation for advanced packaging

Speaker:
Seo Young, Samsung; Atif Afzal, Schrödinger

Abstract:
Advanced packaging allows chiplet integration and maximizes device performance with faster product development cycle, lower cost, and higher yield. As the package size becomes bigger and the device is getting more complicated, there is growing motivation to employ manufacturing process simulation, Artificial Intelligence (AI) assisted process optimization, yield and reliability prediction, rather than conventional methods, to ramp the yield and to ensure the reliability of a new product. The key for an accurate process simulation model is to input precise material properties, such as modulus, Coefficient of Thermal Expansion (CTE), dielectric constant, glass transition temperature, etc., which could change non-linearly with temperature, moisture, as well as other environmental factors and process conditions. Molecular modeling and molecular dynamics can provide insights into post chemical reactions or physical transformations via atomic and molecular simulations. Lithography Techniques for Redistribution Layer (RDL) fabrication are the foundation of Advanced Packaging techniques, such as Fan Out Wafer Level Packaging (FOWLP), Fan Out Panel Level Packaging (FOPLP), 2.5D, 3D, and 3.5D packaging with RDL interposers. The continuous scaling-down of critical dimensions (CDs) in advanced packages, including via diameters, routing line and space (L/S), to a few microns, or submicron level, as well as the increasing number of RDL layers at panel scale pose significant challenges in RDL lithography techniques. For example, the Photo Imageable Dielectric (PID) or other build-up dielectric materials used in multilayer RDL fabrication are polymers, having low Young’s modulus, high CTE, and big volume shrinkage after curing. These material properties could cause fabrication process induced warpage and surface topography deformations, such as non-planarity, roughness, contamination, defects, and dimensional variations, which could potentially lead to massive yield loss when forming fine features during the multilayer RDL patterning. This paper presents material simulation methodologies based on quantum mechanics (QM), molecular dynamics (MD), and Machine Learning (ML), which are adopted to predict the material properties of a PID material, including glass transition temperature (Tg), CTE, mechanical properties, dielectric properties, as well as volume shrinkage after curing. Comparison between the simulation results and the experimental data is performed to validate the methodology. Similar methodology could be used to predict material properties of other organic packaging materials, which is crucial for building up accurate process, yield, and reliability simulation or digital twin of advanced packaging.

Speaker:

Abstract:
The creation of next-generation display technologies hinges on innovative research strategies and collaborative tools. This presentation highlights how the integration of physics-based simulations, machine learning (ML), and a cloud-enabled platform accelerates the discovery and refinement of advanced optoelectronic materials. We introduce the Schrödinger digital chemistry platform, which facilitates advanced simulations of optoelectronic materials, spanning from individual molecules to thin films developed via vacuum deposition or solution processing. This platform’s automated capabilities predict key material properties such as electronic transitions, hyperfluorescence, charge carrier mobility, refractive index, thermophysics, interfacial mixing, and molecular orientation. We then explore the synergy between physics-based simulations and ML, which significantly streamlines the materials discovery process. By analyzing large datasets and identifying trends, ML allows for faster predictions of material properties. An active learning screening process efficiently pinpoints promising candidates based on multiple properties, all while reducing computational cost. Further, we discuss genetic optimization algorithms that drive the development of new materials for electroluminescent devices. These algorithms emulate natural selection, refining material properties iteratively to uncover high-performance compounds tailored to specific targets. When combined with high-throughput screening, this approach accelerates the exploration of chemical space, leading to rapid material advancement. Lastly, we introduce Schrödinger’s LiveDesign, a web-based collaboration platform that enhances modern R&D by integrating advanced modeling, data management, and ideation. LiveDesign empowers research teams to collaborate effectively, regardless of geographic location, supporting a seamless end-to-end research workflow.

Screening Antioxidant Ingredients Using Machine Learning and Physics-based Modeling 

Speaker:
Haidong Liu, Senior Scientist, Schrödinger

Abstract:
Antioxidants are an important ingredient for cosmetic products to alleviate oxidative stress. While high-throughput screening for new antioxidant candidates still remains challenging experimentally. And the data-driven machine learning models would require the input of a reliable dataset. Here we present an efficient computational approach that combines the physics-based and machine learning tools to address this issue, and this approach only uses molecular structures as inputs.

We used molecular quantum mechanical (QM) calculation and machine learning to predict the antioxidant activity through hydrogen atom transfer (HAT) mechanism. We first constructed a library of flavonoid structures and then calculated the hydrogen dissociation energies of the hydroxyl group in solvents using QM. The machine learning model was trained and validated using the hydrogen dissociation energies from QM calculations. We can easily screen thousands of molecules, and this physics-based and machine learning combined approach can be used for other properties.

Discovering Low-Viscosity Molecules Using an Integrated Physics-Based Modeling, High-Throughput Screening and Active Learning Approach (1)— Screening from the GDB Database

Speaker:
Atif Afzal, Principal Scientist

Abstract:
The discovery of low-viscosity molecules is crucial for the development of next-generation batteries and capacitors. Large molecular libraries available in the literature provide a valuable resource for identifying promising candidates. In this study, we utilized the GDB database1, one of the largest repositories of small molecules, to identify low-viscosity molecules. We employed and benchmarked molecular dynamics methods to accurately compute the dynamic properties without the need for synthesis or empirical testing, validating our calculations against experimental data. However, the number of molecules of interest from the GDB database is too large (several hundreds of thousands), making it impractical to identify promising candidates using purely physics-based models due to computational costs. Therefore, we implemented advanced machine learning (ML) techniques and smart selection approaches to dramatically reduce the number of physics-based calculations needed. Physics-based simulations of viscosity included both Green-Kubo and Einstein-Helfand approaches allowing for robust calculation across the selected molecules. By employing an active learning approach, we optimized the selection of molecules, enhancing the efficiency of the ML model while targeting low-viscosity candidates. Additionally, we computed the boiling points (BP) of the molecules using ML models trained on experimental BP data. As a result, we identified more than 100 molecules with viscosities less than 0.35 cP and BP above 80°C. We demonstrate that by integrating accurate physics-based models with advanced ML techniques, we can effectively identify top molecular candidates while significantly reducing computational costs.

Prediction of aqueous and non-aqueous solubility using machine learning

Speaker:
Lihua Chen, Senior Scientist

Abstract:
Solubility, the capacity of a solute to dissolve in a solvent, forming a solution, is a crucial design parameter across various materials and life science applications. Due to the high cost of experimental measurements, we have developed quantitative structure-property relationship (QSPR) models to rapidly and accurately predict aqueous solubility in water and non-aqueous solubility in organic solvents. For this purpose, we gathered 14,485 room temperature aqueous solubility data points and 45,313 temperature-dependent non-aqueous solubility data points from literature and open-source databases. Additionally, we incorporated advanced cheminformatics-based, graph-based, and physics-based descriptors computed through classical molecular dynamics to optimize machine learning performance. These models can significantly streamline molecular discovery by providing rapid, accurate solubility predictions, reducing the need for costly experiments, and accelerating the identification and optimization of promising candidates.

    • Set up a LiveReport as Read-Only or Hidden during creation in an updated Create LiveReport dialog
    • The following menu items have been consolidated into an “Edit LiveReport…” menu: Rename, Move to Folder, Make Read Only and Make Editable, Make Hidden and Make Visible
    • Admins can update Read-Only LiveReports to make them editable
    • Unhide a subset of compounds by clicking on a link in the LiveReport footer and selecting the compound IDs in a dialog
  • Documentation
    • The ? button in LiveDesign now directs to online documentation as is done elsewhere in the Schrödinger platform. Users will be directed to log into their Schrödinger web account that will be verified with a code to their email; if they do not have a web account, they will need to sign up for one.
  • Copy values from the Form spreadsheet, table, and ID widgets to the clipboard
  • Search and filter for a column name in the Create MPO dialog when adding a constituent column from the LiveReport
  • Click a link in a 3D cell for a 3D Generic Entity and Explicit Ligand Designer to view the 3D structure in Maestro
  • Entities appear in a LiveReport more quickly after a reaction enumeration, R-group enumeration, file upload, Maestro upload, and LDClient upload
  • LDClient’s API for retrieving FFC columns “get_freefrom_column_by_id” will now include an “updated_at” field containing a long corresponding to the timestamp that the FFC was last updated
  • Landing Page: View recent published experimental data from the Compound’s Page

What’s Been Fixed

  • Adding an entity to an Advanced Search, by searching for its ID, would show an unresponsive dialog, and now shows a dialog that accept an ID.
  • Complex filters would not accept a pasted biologic sequence, and would fail to filter to that sequence, but now accept pasted biologic sequences.
  • Creating a LiveReport from a template in the Landing Page would not open the newly created LiveReport, and now opens the LiveReport in a new browser tab.
  • If an entity is imported to multiple projects, purging the entity from one of the projects will make it disappear from that project only. Only one file entry now appears in the Manage Files Dialog for a multi-entity import through CSV, ZIP, and FASTA.
  • String type of entity relationship metadata is supported in DI by adding a DI mapping for relationship and relationship metadata.
  • The column “Structure Class” has been renamed to “Entity Type” in the Data & Columns tree
  • Pasting aromatic structures into the sketcher would flip chirality on structures containing a pyrrole, and now the chirality is maintained.
  • When entering FFC date values via LDClient, users must now use the YYYY-MM-DD format. If the date is entered in an incorrect format, the system will return a 400 error with the message: ‘Date must be in YYYY-MM-DD format.’
  • Forms kanban widgets would show a pin icon beside the kanban tile, and now pin icon does not appear in kanban widgets.
  • Unpinning a row now works as expected.
  • Model results with multiple values in a cell would show a different order of values if the LiveReport was duplicated, and now show the same order in the duplicated LiveReport as the origin LiveReport.
  • The Guanidine group in Arginine incorrectly displayed a carbon with five bonds in the 3D visualizer, and now accurately represents the chemistry, showing the correct bonding structure for Arginine residues.
  • Reordering of R-group scaffolds will work for newly added or deleted scaffold without page refresh in SAR analysis(R-group decomposition).
  • The deleted docked poses will no longer reappear, ensuring a clean and organized workspace. Each new pose generated after clicking “predict pose” will be sequentially named, allowing for easy tracking (e.g., “docked_ligand_4” following the deletion of “docked_ligand_3”).
  • Changing the model’s name via Admin panel will get correctly reflected in the Ligand Designer.
  • Targets would remain visible in the 3D visualizer after unchecking the display checkbox and then selecting a different entity, and now the Target display checkbox remains unchecked and the Target is not visible.
  • Copying a LiveReport from one project to another would grant the destination project ACLs to any model within the LiveReport, even if the Model’s Protocol did not provide access to the destination project. Now, the model column will be “dummified” and not visible in the destination project if the Protocol does not provide access to that project.
  • Models with dependent parameterized models will not show an error when archived, and all of its dependent parameterized models will also get archived. A dialog box will appear stating the number of dependent parameterized models that will be archived.
