Deriving factual information from WHO COVI... (1)

 WHO has posted a CSV that's frequently updated with COVID abstracts. A simple PubMed search reveals thousands of abstracts too. So here's an NLP pipeline to mine these and extract meaningful sentences/facts using Stanford Open Information Extractor and Biological entity tagging. #knime #naturallanguageprocessing #textanalytics #textmining #covid19 #nlp #datascience #WHO

Antiviral activity multiclass Predictor (1)

• Download

A simple multi-class antiviral activity predictor based on expanded Pubchem fingerprints and random forest algorithm. Seems to work well to perform quick screens for antiviral molecules.Download training data from CTD (http://ctdbase.org/downloads/) or  use this preprocessed version https://www.myexperiment.org/files/2285.html. Write to me at rajeev.gangal@gmail.com regarding any queries.I make no claim that the predictive model is accurate for clinical hypotheses or that it will find mo...

Genetic Algorithms for BIOISOSTERIC Struct... (1)

• Download

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.

SAR by Rgroup decomposition (1)

• Download

This workflow showcases a simple way to use Rgroup decomposition for SAR analysis.Once R-groups are obtained for several sites on the Scaffold, molecular properties like logP, TPSA, number of heavy/hetero-atoms, various kinds of ring counts are calculated.While medicinal chemistry purists may decry calculating properties for fragments/R-groups, correlating these at each site with Ki (or activity) shows up interesting trends.It's immediately apparent if increasing logP at a given site incr...
