DrugCLIP: Contrastive Protein-Molecule Representation Learning for Virtual Screening

Official code for the paper "DrugCLIP: Contrastive Protein-Molecule Representation Learning for Virtual Screening", accepted at Neural Information Processing Systems, 2023. Currently the code is a raw version, will be updated ASAP. If you have any inquiries, feel free to contact billgao0111@gmail.com

Requirements

same as Uni-Mol

rdkit version should be 2022.9.5

Data and checkpoints

https://drive.google.com/drive/folders/1zW1MGpgunynFxTKXC2Q4RgWxZmg6CInV?usp=sharing

It currently includes the train data, the trained checkpoint and the test data for DUD-E

Training data

The dataset for training is included in google drive: train_no_test_af.zip. It contains several files:


dick_pkt.txt: dictionary for pocket atom types

dict_mol.txt: dictionary for molecule atom types

train.lmdb: train dataset

valid.lmdb: validation dataset

Use py_scripts/lmdb_utils.py to read the lmdb file. The keys in the lmdb files and corresponding descriptions are shown below:


"atoms": "atom types for each atom in the ligand" 

"coordinates": "3D coordinates for each atom in the ligand generated by RDKit. Max number of conformations is 10"

"pocket_atoms": "atom types for each atom in the pocket"

"pocket_coordinates": "3D coordinates for each atom in the pocket"

"mol": "RDKit molecule object for the ligand"

"smi": "SMILES string for the ligand"

"pocket": "pdbid of the pocket",

The dataset is compiled from the PBDBind dataset, containing a combination of authentic protein-ligand complexes and those generated through HomoAug, a technique for augmenting data with homology-based transformations.
