What problem does it solve?

Structure-Activity Relationship (SAR) analysis helps you understand which parts of a molecule drive activity and what modifications could improve potency or drug-like properties, without relying on guesswork.

Core Features & Use Cases

• Analog-by-analog comparisons: Systematically evaluate matched molecular pairs to connect single structural changes to expected activity and property shifts.
• Pharmacophore extraction: Identify essential hydrogen-bonding, hydrophobic, charged, and aromatic features and their spatial relationships that likely explain activity.
• Scaffold hopping & optimization: Propose bioisosteric changes and structural optimization strategies (including natural-product SAR patterns) while flagging risks like over-optimization, PAINS-like motifs, and synthetic difficulty.
• Use case: For a compound candidate found in the OSPF Ayurveda KG, generate a prioritized set of structural modification hypotheses that preserve key binding features while improving ADMET-relevant properties.

Quick Start

Use the sar-analyst skill to analyze the SAR drivers and propose specific structure changes for the query molecule using the project’s processed CSV datasets containing SMILES and descriptors.
