Compound Similarity Analysis
The identification of small molecules with similar chemical properties plays a crucial role in drug discovery. Compound similarity analysis involves comparing molecular structures to uncover compounds that exhibit similarity in key physicochemical properties, pharmacophores, and biological activities. This analysis is instrumental in identifying lead compounds, predicting biological activities, and exploring structure-activity relationships (SAR) in drug design.

Introduction of Compound Similarity Analysis
Compound Similarity Analysis is a key approach in Computer-Aided Drug Design (CADD) that involves comparing chemical structures of compounds to assess their similarity or likeness. It can be classified into two main categories: Ligand-based and Structure-based similarity analysis. Ligand-based similarity analysis relies on comparing the chemical properties or fingerprints of compounds, while structure-based similarity analysis involves the comparison of three-dimensional structures or pharmacophores.
Our Service
Structure-Based Compound Similarity Analysis
We use state-of-the-art software for assessing the similarity between different chemical compounds based on their structural attributes. This evaluation offers a deeper understanding of physicochemical properties.
Property-Based Compound Similarity Analysis
This involves analyzing numerous properties of compounds, such as size, shape, charge, hydrophobicity, and polarity. By comparing these properties, we provide crucial insights into the behavior of compounds.
Fingerprint-Based Similarity Analysis
We create unique fingerprints for each compound, indicating their specific attributes. This technique allows us to classify compounds, predict their activity spectra, and link similar compounds. It is an efficient method to manage vast compound databases.
Pharmaco-kinetic and toxicological profile analysis
Our team provides a comprehensive pharmacokinetic (PK) and toxicity profile of candidate compounds. This involves a detailed study of absorption, distribution, metabolism, excretion, and toxicity (ADME/T) properties, paving the way for efficacious and safe drugs.
