Pharmaprojects lets researchers track the progress of drugs from bench to patient by exploring drug development by global and country development status, and therapeutic class status.

This database covers the progress of new drug candidates as they enter commercial pharmaceutical research and development programs, and tracks their progress from early preclinical development up to market launch, or to discontinuation if a drug fails at any stage.

Researchers can search drugs by chemical structure and other chemical attributes such as molecular weight or logP, or search by biological targets of the drugs.  Besides searching the database, users can export data and set up alerts.

TRANSFAC is a knowledge-base containing published data on eukaryotic transcription factors (and miRNAs), their experimentally-proven binding sites, and regulated genes. The same data also forms the basis of derived positional weight matrices which can be used with the included tools (Match/FMatch/CMsearch) to search DNA sequences for putative transcription factor binding sites. Transcription factor ChIP-Seq, DNase hypersensitivity and histone methylated intervals from the ENCODE project have been mapped to promoter sequences and complement the binding site data curated from the literature.

Key Capabilities

  • Predict TF binding sites or composite elements within single DNA sequences with Match and CMsearch, using matrices (PWMs) from TRANSFAC or your own
  • Analyze microarray, ChIP-seq and RNA-seq data for over-represented TF-binding sites (FMatch/Step-by-step analysis)
  • Find de novo motifs in sequence sets with the DECOD algorithm and compare them against TRANSFAC matrices
  • Analyze gene sets for the presence of shared miRNA target sites
  • Build custom transcription regulatory networks from experimentally demonstrated factor-DNA and factor-factor interactions
  • Explore detailed reports for transcription factors, their experimentally-characterized binding sites, regulated genes and promoters with mapped regulatory features
  • Download binding fragments and best scoring sites from individual ChIP experiments in FASTA or BED format, or lists of nearest genes, for analysis
