# synspace

**This is early-stage code that is in progress. It is in flux**

This package generates a local chemical space around a given molecule using retro and forward synthesis rules. The reactions used are the 50 robust medchem reactions proposed by [Hartenfeller et al.](https://pubs.acs.org/doi/10.1021/ci200379p). The retrosynthesis is done either via [PostEra Mannifold](https://postera.ai/) if you have an API key, or by reversing the 50 robust reactions. The purchasable building blocks come from the [Purchasable Mcule supplier building block catalogs](https://mcule.com/database/). All of these things can be customized though.

## Installation

```sh
pip install synspace
```

## Usage

Generate local chemical space given a SMILES string
```py
mols, props = synspace.chemical_space('CCC=O')
```
`props` contains information like the synthesis route for the molecules. Note that all synthesis routes are relative to the given molecule (it is assumed to be synthetically feasible).

TODO

Also, this idea is similar to [Dolfus et al.](https://pubs.acs.org/doi/10.1021/acs.jcim.2c00246)
