The MAMMAL Drug-Target Interaction API, available at POST /api/v1/mammal/dti, is a powerful tool within the free Cure Cancer With AI public API. This endpoint is designed to predict the binding affinity between drugs and their target proteins using advanced machine learning techniques. By providing a straightforward way to estimate how strongly a compound binds to a given target, this API addresses a critical challenge in the early stages of drug discovery.
Why This Endpoint Matters
Understanding the interaction between drugs and their targets is a fundamental aspect of drug development. The binding affinity, quantified as the negative logarithm of the dissociation constant (−log₁₀ Kd, or pKd), gives valuable insights into how effectively a drug may work against a specific biological target. Higher pKd values indicate stronger predicted binding, which is essential for prioritizing compounds in the drug discovery pipeline.
Before even entering the lab, researchers can use the MAMMAL API to quickly evaluate the potential effectiveness of various compounds through computational predictions. This not only accelerates the research process but also conserves resources by allowing researchers to triage which compounds to advance in the discovery workflow.
How to Use It
Using the MAMMAL Drug-Target Interaction API is straightforward. The API accepts a POST request at the path /api/v1/mammal/dti and requires a JSON body with specific parameters:
- target_seq: The amino acid sequence of the target protein.
- drug_seq: The SMILES representation of the drug compound.
- norm_y_mean (optional): Override for normalization mean.
- norm_y_std (optional): Override for normalization standard deviation.
The API will respond with a JSON object containing the predicted binding affinity:
{
"data": {
"pKd": 7.45 // Example value
}
}
Here’s a sample curl command to demonstrate how to use this endpoint:
curl -X POST https://curecancerwithai.com/api/v1/mammal/dti \
-H "Authorization: Bearer ccw_live_YOUR_KEY" \
-H "Content-Type: application/json" \
-d '{
"target_seq": "MKTAYIAKQRQISFVKSHFSRQD",
"drug_seq": "CC(=O)OC1=CC=CC=C1C(=C(C)O)C(=O)O"
}'
In this example, replace YOUR_KEY with your actual API key. The request includes the protein sequence and drug SMILES notation, and the response will provide the predicted pKd value.
What You Can Build
The MAMMAL Drug-Target Interaction API opens up numerous possibilities for researchers and developers:
- Compound Library Ranking: Use the API to evaluate and rank a library of compounds against a specific target protein, helping to identify the most promising candidates for further study.
- Hit Triage: Quickly assess and filter hits from high-throughput screening assays before committing to more costly and time-consuming experiments.
- Discovery Pipeline Integration: Add binding affinity predictions as a signal in your drug discovery pipeline, enhancing decision-making processes and resource allocation.
- Research Tools: Develop applications or dashboards that provide visualizations of drug-target interactions, facilitating better insights for researchers.
