TTD

TTD provides a curated database of therapeutic targets, associated drugs, and annotations to support drug discovery and target validation.

Key Features:

• Extensive Data Coverage: Contains data on 348 successful therapeutic targets, 292 clinical-trial targets, 1,254 research targets, 1,514 approved drugs, 1,212 clinical-trial drugs, and 2,302 experimental drugs linked to primary targets, with later releases expanding to 1,894 targets, 560 diseases, and 5,028 drugs from initial figures of 433 targets, 125 diseases, and 809 drugs.
• Drug Information: Includes 3,382 small-molecule drug entries and 649 antisense drug entries with available structural and sequence data.
• Search and Similarity Functions: Provides drug mode-of-action annotations, recursive search functionality, and similarity-searching capabilities for targets and drugs.
• Data Retrieval: Supports customized search queries and full dataset downloads.
• Standardized Target Identification: Employs standardized target identifiers to ensure consistency across records and studies.

Scientific Applications:

• Target Identification and Prioritization: Enable identification and prioritization of candidate therapeutic targets for drug discovery projects.
• Mechanism-of-Action Analysis: Facilitate analysis of drug mechanisms of action through curated drug–target relationships.
• Preclinical and Clinical Research Support: Provide annotated target and drug data to inform decision-making in preclinical and clinical development stages.
• Hypothesis Generation and Validation: Support generation and validation of hypotheses by supplying comprehensive target–drug datasets.

Methodology:

Data are integrated and regularly updated from scientific literature, patents, and other sources; the database implements standardized target identifiers and supports similarity searching and recursive search functionality.
