      "synthesis_summary": "Best therapeutic candidate among three hypotheses. Target is druggable with structural validation. Existing chemical matter (SR9009, SR9011) demonstrates mechanism but requires medicinal chemistry optimization for CNS penetration and safety. EAE data supports neuroinflammatory modulation but lacks direct neurodegeneration model validation. Requires partnership with nuclear receptor-focused CRO for lead optimization. First-in-class CNS opportunity but significant safety liabilities (hepatotoxicity, anemia) require careful monitoring in clinical development."
