Fundamentals of Cheminformatics and Chemical Database Search

Finding specific molecular patterns and substructures across vast chemical databases is an essential skill in modern computational chemistry and early-stage drug discovery. This course introduces the core concepts and techniques required to manage, query, and analyze chemical information effectively. You will begin by understanding how chemical structures are represented digitally, including molecular graphs, SMILES strings, and fingerprints. From there, you will learn how to search molecular databases, perform exact and substructure queries, and filter compounds by chemical properties. What you will learn: - Understand fundamental chemical representation formats, including SMILES and chemical graphs - Learn how chemical databases index and organize molecular properties and research metadata - Apply substructure and similarity search algorithms to identify target compounds - Practice generating and interpreting molecular fingerprints for computational screening - Understand property calculation and basic molecular descriptor generation using standard open-source tools - Explore modern computational workflows connecting database retrieval with virtual screening The course starts with essential terminology and structural representations before progressing through query methods, database architectures, and computational analysis techniques. Written explanations and structured exercises help reinforce every concept step by step. This course is designed for beginners in cheminformatics, bioinformatics, and chemistry who want to learn digital chemical data management without prior computational experience.
