Workflow Integrative data mining of chemical compou... (1)

Thumb
This workflow downloads ligand data for hepatic Organic Anion Transporting Polypeptides (OATPs) from five different open sources (CHEMBL, Metrabase, USFC-FDA Transportal, IUPHAR, and Drugbank) in an semi-automatized fashion. This workflow can be adopted to any other ligand data showing an (in)activity against membrane transporter. If missing, structural file format is mapped via PubChem webservices. Pre-curated compounds are subjected to standardization procedure (Atkinson standardization scr...

Workflow Genetic Algorithms for BIOISOSTERIC Struct... (1)

Thumb
Genetic algorithm workflow to generate novel structures by recombination and mutation and that uses an ML model as a fitness function. Both the fitness function and the fingerprints modified in the model should be the same. ML model cannot have any descriptors other than given fingerprint.Reverse molecular mapping/generation is not part of this workflow and can be done by creating a large Structure-FP database.

Workflow Substructure querying | R-group decomposit... (1)

Thumb
This workflow creates maximum common substructure (MCS) out of the provided structures and then substructure mining using MCS as a structural query is performed. Obtained hits are then subjected to R-group decomposition to explore their functional groups. Optionally, physicochemical descriptors for individual functional groups can be calculated.

Workflow Scaffold Analysis | Statistical analysis o... (1)

Thumb
This workflow performs an extraction and statistical analysis of Murcko scaffolds for compounds being active against (a) different target(s). Specifically, target-wise detection of Murcko Scaffolds in active versus inactive compounds, filtering steps by removing too generic scaffold (i.e., number of rings equals to one OR number of heteroatoms in a ring is zero or one), calculating the frequency of a particular scaffold which appears frequently in the active over inactive class, applying Fish...

This workflow first conducts a search and downloads the PMIDs for all publications in PubMed and PMC that match a particular query using the Europe PMC Articles API. In a second phase, the workflow fetches the ChEBI annotations for all these publications using the Europe PMC Annotations API.
