Drugs targeting the central nervous system must meet stringent criteria for both efficacy and safety, including their ability to penetrate the blood-brain barrier (BBB). 
This model predicts the likelihood of small-molecule drugs crossing the BBB, a critical factor in CNS drug development. 
The molecules are represented using SMILES (Simplified Molecular Input Line Entry System) strings.

The model is a fine-tuned version of IBM's biomedical foundation model, ibm/biomed.omics.bl.sm.ma-ted-458m [1], which was trained on over 2 billion biological samples 
across multiple modalities, including proteins, small molecules, and single-cell gene expression data.

The fine-tuning was performed using the MoleculeNet BBBP dataset [2]. For benchmarking, we employed predefined training, validation, and testing splits 
provided by MolFormer [3], sourced from the dataset referenced in [4].

A simple example for using `ibm/omics.bl.sm.ma-ted-458m.moleculenet_bbbp`:

```python
from mammal.examples.molnet.molnet_infer import load_model, task_infer

smiles_seq = "C(Cl)Cl"

task_dict = load_model(task_name="BBBP", device="cpu")
result = task_infer(task_dict=task_dict, smiles_seq=smiles_seq)
print(f"The prediction for {smiles_seq=} is {result}")
```
