A parameter-efficient molecular featuriser that generalises well to biological tasks thanks to the effective pre-training on biological and quantum mechnical datasets.

The model has been introduced in the paper 𝙼𝚒𝚗𝚒𝙼𝚘𝚕: A Parameter-Efficient Foundation Model for Molecular Learning, published in the ICML workshop on Accessible and Efficient Foundation Models for Biological Discovery in 2024.

Usage

Embeddings can be generated in four lines of code:

from minimol import Minimol
model = Minimol()
smiles = [
    'COc1ccc2cc(C(=O)NC3(C(=O)N[C@H](Cc4ccccc4)C(=O)NCC4CCN(CC5CCOCC5)CC4)CCCC3)sc2c1',
    'Nc1nc(=O)c2c([nH]1)NCC(CNc1ccc(C(=O)NC(CCC(=O)O)C(=O)O)cc1)N2C=O',
    'O=C1CCCN1CCCCN1CCN(c2cc(C(F)(F)F)ccn2)CC1',
    'c1ccc(-c2cccnc2)cc1',
]
model(smiles)
>> A list of 4 tensors of (512,) shape

Installation

Pip

When used with cuda, use nvcc --version to see which version of the driver is installed on your machine, to select the wheel (cuXXX):

pip install torch-sparse torch-cluster torch-scatter -f https://pytorch-geometric.com/whl/torch-2.3.0+cu124.html
pip install minimol

Local

git clone git@github.com:graphcore-research/minimol.git 
cd minimol
mamba env create -f env.yml -n minimol_venv
mamba activate minimol

To install mamba see the official documentation.

Performance

The model has been evaluated on 22 benchmarks from the ADMET group of Therapeutics Data Commons (TDC). These are the results when comparing to MolE and TOP5 models from the TDC leaderboard (as of June 2024):
