Anti-Inflammatory Effects and Photo- and Neuro-Protective Properties of BIO203, a New Amide Conjugate of Norbixin, in Development for the Treatment of Age-Related Macular Degeneration (AMD)

9'-cis-norbixin (norbixin/BIO201) protects RPE cells against phototoxicity induced by blue light and N-retinylidene-N-retinylethanolamine (A2E) in vitro and preserves visual functions in animal models of age-related macular degeneration (AMD) in vivo. The purpose of this study was to examine the mode of action and the in vitro and in vivo effects of BIO203, a novel norbixin amide conjugate. Compared to norbixin, BIO203 displays improved stability at all temperatures tested for up to 18 months. In vitro, BIO203 and norbixin share a similar mode of action involving the inhibition of PPARs, NF-κB, and AP-1 transactivations. The two compounds also reduce IL-6, IL-8, and VEGF expression induced by A2E. In vivo, ocular maximal concentration and BIO203 plasma exposure are increased compared to those of norbixin. Moreover, BIO203 administered systemically protects visual functions and retinal structure in albino rats subjected to blue-light illumination and in the retinal degeneration model of Abca4-/- Rdh8-/- double knock-out mice following 6 months of oral complementation. In conclusion, we report here that BIO203 and norbixin share similar modes of action and protective effects in vitro and in vivo. BIO203, with its improved pharmacokinetic and stability properties, could be developed for the treatment of retinal degenerative diseases such as AMD.
