UNMET NEED
Specialized pro-resolving mediators (SPMs) derived from long-chain omega-3 fatty acids have pro-resolving and anti-inflammatory effects in many acute and chronic pathologies. Protectins are among the most studied SPM members and protectin DX (PDX) has been shown to (i) improve insulin resistance in diabetes models, (ii) reverse lung fibrosis, (iii) ameliorate osteoarthritis progression, and other benefits with potential therapeutic applications.
A major limitation with PDX has been its exorbitant cost of production ($7500/mg), while achieved by biosynthesis with very low yields. Historically, this precluded more extensive in vitro and in vivo studies toward its development as a therapeutic agent.
