ChEMBL 20 incorporates the Pistoia Alliance’s HELM annotation by Richard Holland.
From the post:
The European Bioinformatics Institute (EMBL-EBI) has released version 20 of ChEMBL, the database of compound bioactivity data and drug targets. ChEMBL now incorporates the Hierarchical Editing Language for Macromolecules (HELM), the macromolecular representation standard recently released by the Pistoia Alliance.
HELM can be used to represent simple macromolecules (e.g. oligonucleotides, peptides and antibodies) complex entities (e.g. those with unnatural amino acids) or conjugated species (e.g. antibody-drug conjugates). Including the HELM notation for ChEMBL’s peptide-derived drugs and compounds will, in future, enable researchers to query that content in new ways, for example in sequence- and chemistry-based searches.
Initially created at Pfizer, HELM was released as an open standard with an accompanying toolkit through a Pistoia Alliance initiative, funded and supported by its member organisations. EMBL-EBI joins the growing list of HELM adopters and contributors, which include Biovia, ACD Labs, Arxspan, Biomax, BMS, ChemAxon, eMolecules, GSK, Lundbeck, Merck, NextMove, Novartis, Pfizer, Roche, and Scilligence. All of these organisations have either built HELM-based infrastructure, enabled HELM import/export in their tools, initiated projects for the incorporation of HELM into their workflows, published content in HELM format, or supplied funding or in-kind contributions to the HELM project.
