Scaffold Hopping / Fragment Linking / Ligand Growing / R-Group Screening / Medicinal Chemistry Transformations / Pharmacophores / Fragment Databases

The course will focus on fragment-based drug design tools in MOE. Combinatorial fragment design and scaffold replacement in the receptor active site will be covered in detail, along with approaches for fragment linking and growing. A method for generating a series of closely related derivatives through medicinal chemistry transformations will also be presented. Finally, the use of pharmacophores and 2D/3D descriptors to guide drug design processes will be discussed.

Protein Engineering / Protein Properties / Developability / Hot Spot Analysis / Antibody Modeling / Humanization / Molecular Surfaces

The course 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 identification of 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.
