Antibody structure prediction / Conformational ensembles / Descriptor calculations / Property prediction / Developability / Cloud computing

Predicting potential liabilities such as aggregation or viscosity is a key step in monoclonal antibody development. Computational property prediction methods are routinely used in the selection and optimization of candidate antibodies. High-quality property prediction involves prediction of ensembles of 3D structures at specified pH to reduce sensitivity to single conformational states. We will present 3dpredict/Ab, a solution that enables ensemble-based predictions of antibody developability descriptors and putative liabilities. 3dpredict/Ab allows for out-of-the-box SaaS automation and integration of such complex simulations of hundreds or thousands of sequences, making them accessible and efficient.

Virtual screening compound libraries / Descriptors / Molecular Fingerprints / QSPR modeling / Database filtering / Pharmacophore modeling / Pharmacophore-guided docking / Template-based docking / Compound design

This workshop explores the suite of MOE applications for small-molecule virtual screening. Participants will learn to prepare small-molecule databases for screening, filter databases using substructure matching and property values, and build QSAR/QSPR models and fingerprint similarity models as screening filters. The session will cover creating and searching pharmacophore queries and performing small-molecule docking. A complete virtual screening workflow will be presented, including the creation of de novo structures using MOE’s Scaffold Replacement and Medchem transformation tools.

Important milestones will be recorded through Capture for review and to allow for sharing the design session with colleagues. The docking module and its application to assess ligand flexibility will be discussed. A protocol for aligning and superposing protein complexes in the context of protein selectivity will be studied.

PSILO / Central macromolecular repository / 3D Query searching / Pocket similarity / MOE-project / Project search / Organizing and centralizing project data / Protein family modeling

This workshop covers the searching and analysis of structural data in PSILO®, as well as the organization and mining of structural families using MOE-Project. Participants will learn to consolidate macromolecular and protein-ligand structural data, generate and navigate advanced queries, and streamline analysis with 3D contact and protein pocket similarity searches. The session also covers organizing structure-based drug design projects, aligning protein families, configuring MOE-Project databases, and using Protein-Ligand Interaction Fingerprints (PLIF) analysis to compare ligand binding modes. Attendees will gain practical skills for efficient structural data mining and project management.

Protein Engineering / Protein Properties / Protein Contacts / Developability / Molecular surfaces / Hot spot analysis / Antibody modeling

This workshop covers approaches for structure-based antibody design and includes protein-protein interactions analysis, in silico protein engineering, affinity modeling and antibody homology modeling. The interaction of a co-crystallized antibody-antigen complex will be studied by generating and examining molecular surfaces and visualizing protein-protein contacts in 3D. Antibody properties will be evaluated using specialized calculated protein property descriptors and analyzing protein patches. The application of protein engineering tools for affinity and property optimization of antibodies in the context of developability will be studied. Antibody homology modeling optimization examples will include identifying glycosylation sites and their selective modification using a specialized MOE Project antibody database. All the steps necessary for high throughput antibody homology modeling workflow from sequence to structure to property calculations for developability analysis will be described.
