Rdkit chemical reaction
Web1. I am trying to create a KNIME workflow that would accept a list of compounds and carry out bioisosteric replacements (we will use the following example here: carboxylic acid to tetrazole) automatically. NOTE: I am using the following workflow as inspiration : RDKit-bioisosteres (myexperiment.org). This uses a text file as SMARTS input. Web4. SMARTS - A Language for Describing Molecular Patterns. Substructure searching, the process of finding a particular pattern (subgraph) in a molecule (graph), is one of the most important tasks for computers in chemistry.It is used in virtually every application that employs a digital representation of a molecule, including depiction (to highlight a …
