Automated Code Generation
Generate Code
Let us take a simple task in the pharma domain, where we could focus on predicting the solubility of molecules, which is a fundamental property relevant to drug formulation and efficacy. A basic machine learning model can be trained to predict solubility from molecular descriptors or fingerprints, which can be computed from the SMILES representation of the molecules.
Task Description
The task is to predict the solubility of molecules based on their chemical structures encoded as SMILES strings. This will involve:
Data Preparation: Extracting molecular descriptors or fingerprints from SMILES strings.
Model Building: Creating a regression model using a machine learning library like scikit-learn.
Training and Prediction: Training the model on known data and using it to predict solubility for new molecules.
Code Snippet Requirements
To implement this simpler task, you'll need:
RDKit for handling chemical information and generating molecular descriptors.
Scikit-learn for creating and training the regression model.
Example Code Snippet
Here's a straightforward Python code snippet demonstrating how to predict molecular solubility using RDKit and scikit-learn:
from rdkit import Chem
from rdkit.Chem import Descriptors
import pandas as pd
from sklearn.model_selection import train_test_split
from sklearn.linear_model import LinearRegression
from sklearn.metrics import mean_squared_error
# Function to compute molecular descriptors
def compute_descriptors(smiles):
mol = Chem.MolFromSmiles(smiles)
return Descriptors.MolWt(mol), Descriptors.MolLogP(mol), Descriptors.NumHAcceptors(mol), Descriptors.NumHDonors(mol)
# Prepare dataset
data = {
'SMILES': ['CC(=O)OC1=CC=CC=C1C(=O)O', 'CC(C)C(C(=O)COC(=O)C1=CC=CS1)N1CCCC1C(=O)O'], # Example SMILES
'Solubility': [-2.18, -3.10] # Example solubilities
}
df = pd.DataFrame(data)
df[['MolWt', 'LogP', 'HAcceptors', 'HDonors']] = df['SMILES'].apply(lambda x: pd.Series(compute_descriptors(x)))
# Split data into training and testing
X_train, X_test, y_train, y_test = train_test_split(df[['MolWt', 'LogP', 'HAcceptors', 'HDonors']], df['Solubility'], test_size=0.2, random_state=42)
# Create and train a linear regression model
model = LinearRegression()
model.fit(X_train, y_train)
# Make predictions and evaluate the model
y_pred = model.predict(X_test)
mse = mean_squared_error(y_test, y_pred)
print(f'Mean Squared Error: {mse}')
# Predict solubility for a new molecule
new_smiles = 'C1=CC=C(C=C1)C(=O)O' # Example new SMILES
new_features = compute_descriptors(new_smiles)
predicted_solubility = model.predict([new_features])
print(f'Predicted Solubility: {predicted_solubility[0]}')
Notes
This script assumes you have a dataset of molecules with known solubility. In practice, you would need a larger dataset to train a reliable model.
The example uses a linear model for simplicity, but more complex models might provide better accuracy depending on the data.
This task provides an opportunity to learn how molecular properties can be used to predict biologically relevant outcomes in a straightforward, computationally accessible manner.
