Structure Activity Relationship (SAR) Study

Structure activity relationship (SAR) study is a crucial aspect of drug discovery and development. It is a systematic approach used to investigate the relationships between the chemical structure of a molecule and its biological activity (such as solubility, potency, selectivity, metabolic stability, permeability, toxicity, pharmacokinetics, tissue distribution, in vivo efficacy). By studying the effects of structural modifications on a compound's activity, researchers can identify key structural features that are essential for its biological function. This information is invaluable for the rational design of new drugs with improved potency, selectivity, and pharmacokinetic properties. At our company, we offer comprehensive SAR services to support drug discovery projects. Our team of experienced computational and medicinal chemists and biologists collaborates closely to evaluate the biological activity of each compound systematically by using state-of-the-art analytical techniques and high-throughput screening assays.

Applications of SAR Study

SAR studies are used in various stages of drug discovery and development, including:

• Hit-to-lead: SAR study helps to optimize the chemical structure of compounds to improve their biological activity and reduce toxicity, ultimately guiding the selection of lead compounds for further development.
• Lead Optimization: SAR data is used to guide the modification of lead compounds to improve potency, selectivity, and pharmacokinetic properties.
• Scaffold Hopping: SAR findings can help identify new chemical scaffolds with similar biological activity, allowing for the development of novel drug candidates.
• Mechanism of Action Studies: By understanding how changes in a compound's structure affect its activity, researchers can gain insights into the molecular mechanisms underlying its biological effects.

Our SAR Study Methodology

At our company, we employ both experimental or computational methods to perform SAR study.

Experimental SAR Techniques

Experimental SAR studies involve synthesizing and testing a series of compounds related to a known active compound. These compounds are then evaluated by experimental techniques for their biological activity, and the data is used to uncover which structural features contribute to the compound's effectiveness. Here are some common experimental SAR techniques:

• Biological Assays: These assays measure how well a compound interacts with a specific biological target, such as an enzyme or receptor. By evaluating the compound's effect on the target, researchers can determine potential therapeutic value of the specific compound structure.
• Pharmacokinetic Studies: These studies focus on understanding how a compound is absorbed, distributed, metabolized, and excreted in the body. By studying the compound's pharmacokinetics, researchers can evaluate bioavailability of the specific compound structure.
• Toxicological Studies: Toxicological studies examine the compound's impact on different organs and systems to evaluate safety of the specific compound structure for human use.

Computational SAR Methods

Computational SAR methods leverage Machine Learning models to predict the biological activity of new compounds based on their chemical structure. These models are trained on data obtained from experimental SAR studies and can be used to guide the design of novel drug candidates. The following computational SAR techniques are commonly utilized at our company:

• Molecular Modeling: This technique involves using advanced computer software to create three-dimensional models of molecules. By simulating the interactions between molecules and their biological targets, researchers can gain insights into how the compounds function.
• Quantitative Structure-activity Relationship (QSAR) Modeling: QSAR models utilize Artificial Intelligence to establish relationships between a compound's chemical structure and its biological activity. By analyzing these relationships, researchers can predict the activity of new compounds and optimize their structure for enhanced efficacy.
