A Practical Synthesis of m-Prostaglandin E Synthase-1 Inhibitor MK-7285
摘要:
A practical, kilogram-scale chromatography-free synthesis of mPGE synthase I inhibitor MK-7285 is described. The route features a convergent assembly of the core phenanthrene unit via amide-directed ortho-metalation and proximity-induced anionic cyclization, followed by imidazole synthesis and late-stage cyanation.

Activated macrophages overexpress the folate receptor β (FR-β) that can be used for targeted delivery of drugs conjugated to folic acid. FR-expressing macrophages contribute to arthritis progression by secreting prostaglandinE2 (PGE2). Non-steroidal anti-inflammatory drugs (NSAIDs) block PGs and thromboxane by inhibiting the cyclooxygenase (COX) enzymes and are used for chronic pain and inflammation
