Maximally Bridging Rings
This repository contains code to compute one or more maximally bridging rings (MBR) as described in Marth et al, Nature, 2015. These are used as part of a retrosynthetic strategy. The original work described the method and provide an online tool to run the computation on a submitted SDF/MOL file. However no source code was provided. Hence this tool.
The code here can be used to identify the MBR(s) in an input molecule. Currently the output is an SVG depiction of the molecule with the first MBR highlighted in red. The code allows you to access the subset of bridgehead atoms that are maximally bridging.
Note this was a quick hack and hasn't been extensively tested but seems to work on the first few examples in the SI provided by the authors.
The code depends on CDK (1.5.12) and a self-containd JAR file can be built using
mvn clean package
The tool can then be run by specifying a molecule in SMILES format and the molecule title.
java -jar target/MaximallyBridgingRings-1.0-jar-with-dependencies.jar "CC(C)C1CCC2(C3C1C2CC=C3C)C" Copaene
The depiction will be in a file called
