Medchem design moves for generating new compounds

This repository contains a python library for exploring the medicinal chemistry design moves, as reported in publication: "The playbook of Medicinal Chemistry Design Moves, xxx-xxx-xxx" The library is adpated from original mmpdb code

Dependency

• python >=3
• rdkit

Dataset

• please download the design moves (transformation) dataset from here. We provide the design moves from ChEMBL database at radius 3.

How to run programm

python mmpdb mmpCompoundGenerator  --tsmiles "O=S(=O)(c3ccc(n1nc(cc1c2ccc(cc2)C)C(F)(F)F)cc3)N" --transformation_db "chemblDB3.sqlitdb" --replaceGroup "*S(=O)(=O)(N)" --tradius 3 --toutput output.txt --tmin-pairs 100

• note that output file contains more columns than shown above. For clearity only main columns are shown.

Input Options

parameter	meaning
--transformation_db	transformation database file
--tsmiles	input query molecule (in smiles format)
--replaceGroup	fragment to be replace in a query molecule (in smiles format). Note that it must contains * or [*] to indicate attachment point. 1) single cut example *N1CCOCC1, 2) double cut example N1CCOC()C1
--tradius	chemical envionment radius for design move. It must equal to radius of the transformation database. So in this case 3.
--toutput	name of output text file
--tmin-pairs	consider design moves that have at-least tmin-pairs examples. This is in other words the freqency of a design move. For instacne if we set tmin-pairs to 5: it say that consider all design moves that are derived from at-least five MMP pairs.

Output Columns Explanation

column	meaning
original_smi	smiles of a query molecule
transformed_smi	a new design molecule
constant_smi	smiles of constant part i.e. part which did not change
original_frag	fragment in a query to replace
new_frag	new suggested fragment
envsmi	chemical environment of replacementi (design move)
rule_freq	frequency of design move (transformation)
ex_lhs_cpd_id	an example of MMP (left hand compound id) from ChEMBL
ex_rhs_cpd_id	an example of MMP (right hand compound id) from ChEMBL
