ChEMBL BLAST Search

ChEMBL BLAST Search performs BLAST searches of input protein sequences against protein targets in the ChEMBL database to identify homologous sequences and support bioactivity- and target-based analyses.

Key Features:

• Extensive Data Sources: The ChEMBL database includes data extracted from medicinal chemistry literature, neglected disease screening datasets, crop protection data, drug metabolism and disposition information, and patent-derived bioactivity data.
• BLAST-based Sequence Alignment: Performs BLAST sequence alignments against ChEMBL protein targets to detect homologs and infer functional similarity.
• Enhanced Data Annotation: Assays and targets in ChEMBL are annotated using ontologies to provide structured metadata for search results.
• Clinical Relevance: Contains data on targets and indications for clinical candidates.
• Metabolic Pathway Integration: Includes metabolic pathway information for drugs to contextualize pharmacokinetics and interactions.
• Structural Alerts Calculation: Calculates structural alerts to flag potentially hazardous chemical structures or properties.

Scientific Applications:

• Drug Discovery and Development: Enables identification of potential therapeutic candidates and analysis of mechanisms of action via searches against protein targets.
• Target Identification and Validation: Supports validation of putative drug targets and repurposing of existing compounds by identifying target homology.
• Toxicology and Safety Assessment: Structural alerts assist evaluation of safety profiles of bioactive compounds in early-stage development.

Methodology:

Employs BLAST algorithms to perform sequence alignment searches against protein targets in the ChEMBL database to identify homologous sequences and predict functional similarities.
