Pack Workflows for scaffold trend analyses


Created: 2017-06-22 13:01:47 | Last updated: 2018-06-14 09:37:37

These two KNIME workflows were used to process the raw data (retrieved via sql query from ChEMBL) in order to retrieve the final data for scaffold trend analyses as described in the paper: "The rise and fall of a scaffold: A trend analysis of scaffolds in the medicinal chemistry literature" by B. Zdrazil and R. Guha, Journal of Medicinal Chemistry, 2018, 61 (11), pp 4688-4703.

Included are 2 KNIME workflows for data retrieval and processing:1) a KNIME workflow called "Transporter_Profiling_SERT_DAT_HERGlabel" with HERG labels included2) a KNIME workflow called "Transporter_Profiling_SERT_DAT_Ki_IC50_tailored_TH" without HERG labels

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.

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...

Thumb
First part of the workflow for paper "The rise and fall of a scaffold: A trend analysis of scaffolds in the medicinal chemistry literature" by B. Zdrazil and R.

Thumb
KNIME workflow used to retrieve and process data from Open PHACTS for three targets of interest (hSERT, hDAT, hERG). Further, Murcko scaffolds are computed and selectivity trends towards hSERT and hDAT can be studied. Cutt off's for separating actives/inactives are tailored to the specific target and endpoint.Requirements:- Knime v2.11- Open PHACTS Knime nodes version 1.1.0: https://github.com/openphacts/OPS-Knime- KNIME additional community nodes: 'Trusted Community Contributions (2....
