α-Tocopherol-siRNA Conjugate Development

Inquiry

CD Formulation specializes in the development of conjugates that combine α-tocopherol with siRNA. By leveraging the unique properties of α-tocopherol, this service aims to improve the delivery system of siRNA, enhancing its therapeutic impact through increased stability and precise targeting, providing an innovative approach to drug delivery solutions.

Why Does α-Tocopherol Bind to siRNA?

Combining α-tocopherol, a form of vitamin E, with siRNA enhances the delivery mechanism, enabling specific and effective gene suppression. Known for its antioxidant properties, α-tocopherol protects cells from oxidative damage while facilitating membrane penetration due to its fat-solubility. Linking it with siRNA increases stability and absorption, improving gene silencing effectiveness and reducing adverse effects by directing delivery to target cells. This integration of small molecules with nucleic acid technology holds promise for treating diseases, especially cancer and genetic disorders.
