Overview

As drug development continues to evolve, ensuring the safety of potential therapeutic agents is a critical component. hERG plays a key role in this process as it encodes a potassium channel involved in the regulation of the heart's electrical activity. hERG channel dysfunction can lead to severe cardiac arrhythmias and even sudden death. In this context, ligand/structure-based hERG modeling has become an invaluable tool for predicting the potential cardiotoxicity of drug candidates. CD ComputaBio stands at the forefront of this innovative service, providing the pharmaceutical industry with state-of-the-art solutions to improve drug safety.

Our Services

At CD ComputaBio, our ligand/structure-based hERG modeling services include a comprehensive range of solutions designed to assess, predict, and reduce cardiac safety risks associated with drug candidates. Our team of experts utilizes state-of-the-art computational methods to provide the following services:

Ligand-Based hERG Modeling

We utilize the three-dimensional molecular structure and chemical properties of the ligand to predict the interaction of the ligand with the hERG channel, thereby effectively screening for potentially cardiotoxic compounds.

Structure-Based hERG Modeling

We use advanced molecular docking and simulation techniques to analyze the binding patterns and affinities of drug molecules to hERG channels to help identify potential cardiac safety issues.

Quantitative Prediction of hERG Inhibition

Our platform employs QSAR methodology for quantitative prediction of drug activity, which facilitates the decision-making process in the early stages of drug discovery.

Virtual Screening

Our virtual screening service facilitates the discovery of novel therapeutics targeting hERG channels, thereby significantly reducing the time and cost associated with the drug discovery phase.
