Clinical Trials
AI algorithms accelerate the discovery of natural products by integrating microbiome data to identify disease-linked Biosynthetic Gene Clusters (BGCs), purify associated NPs, and validate their therapeutic potential through targeted assays, ultimately leading to clinical trials.
| Method | Strengths | Limitations |
|---|---|---|
| Rule-Based (PRISM, antiSMASH) |
|
|
| ML-Based (DeepBGC, GECCO, SanntiS) |
|

While rule-based techniques like PRISM and antiSMASH are effective for finding unclustered pathways, ML algorithms, including DL and SVM, show advantages in recognizing established BGC classes and discovering novel biosynthesis pathways not captured by canonical rules.
AI in Complex Natural Product Synthesis
Context: Chematica/Synthia, leveraging expert-inspired heuristics and AI, autonomously designed synthesis pathways for complex natural products like callyspongiolide and engelheptanoxide C, achieving human-level performance in a Turing Test. This demonstrates AI's ability to tackle intricate molecular structures.
Impact: This demonstrates the feasibility of automated synthetic planning for intricate NPs, reducing manual effort and accelerating drug development by generating credible and innovative pathways that are largely indistinguishable from human-crafted ones.
AZD-4635
AI-Planned Compound in Clinical Trials
AI tools like ICSYNTH significantly boost R&D productivity by suggesting new synthesis routes. AZD-4635, an adenosine A2A receptor antagonist, exemplifies a compound where AI-assisted planning led to a validated synthesis route, streamlining drug development and demonstrating practical clinical relevance.
