In the case of chemical mentions of the class MULTIPLE, which cover chemical entities that appear in form of separated or unconnected expressions (discontinuous) they are being annotated together in order to generate integrated forms.
ChEBI acts as a reference for chemical entities across multiple domains and includes in its repertoire a wide range of entities from the subatomic scale to complex polymers.
Table 1 Accuracy of multiple tokenizers when tested on the chemical entities of the test set Word Cosine Similarity.
Hybrid drugs featuring two or more potentially bioactive pharmacophores have been recognized as advanced and superior chemical entities to simultaneously modulate multiple drug targets of multifactorial diseases, thus overcoming the severe side effects associated with a single drug molecule.
The sick building syndrome and multiple chemical sensitivity syndrome have been defined as clinical entities in which exposure to chemical inhalants gives rise to disease.
Each corpus contains 3500 documents, with approximately 29500 annotated chemical entities, divided into several classes: SYSTEMATIC, TRIVIAL, FAMILY, FORMULA, ABBREVIATIONS, IDENTIFIERS, MULTIPLE, and NO CLASS.
Beyond the success in isolating new chemical entities amenable to drugs, such as artemisinin, emerging evidence suggested that multiple compounds from herbals might demonstrate synergism.
The use of multiple screening assays to identify such compounds is a convenient and efficient method for identifying chemical entities with specific effects.
Chemical synthesis of heparin is challenging because it requires repositioning several chemical entities called sulfate groups.
The number of new chemical entities has remained rather constant (averaging 37 per year) in the past decade, despite the multiple-fold increase in the number of compounds that are being made and tested.
Multiple crystal structures of CYP3A4 bound with various substrates or inhibitors have been used as templates for docking of new chemical entities to predict sites of metabolism and molecular interactions for drug design.
