Dataset description
As a membrane separating circulating blood and brain extracellular fluid, the blood-brain barrier (BBB) is the protective layer that blocks most foreign drugs. Thus the ability of a drug to penetrate the barrier to deliver to the site of action forms a crucial challenge in developing drugs for central nervous system.
Task description
Binary classification. Given a drug SMILES string, predict the activity of BBB.

Dataset split
Random split on 70% training, 10% validation, and 20% testing
To load the dataset in TDC, type
from tdc.single_pred import ADME
data = ADME(name = 'BBB_Martins')
Model description
Morgan chemical fingerprint with an MLP decoder. The model is tuned with 100 runs using the Ax platform.
from tdc import tdc_hf_interface
tdc_hf = tdc_hf_interface("BBB_Martins-Morgan")
# load deeppurpose model from this repo
dp_model = tdc_hf.load_deeppurpose('./data')
tdc_hf.predict_deeppurpose(dp_model, ['YOUR SMILES STRING'])
