•Xanthan gum-based omega-3 PUFA-containing hydrogels and microspheres were prepared.•The materials were characterized for size, swelling degree and loading efficiency.•The xanthan gum-based materials showed antioxidant efficacy in vitro.•Omega-3 PUFAs inhibited more efficiently colorectal cancer cell growth when enclosed.•Enclosed omega-3 PUFAs powerfully inhibited colorectal cancer cell proliferation.
Xanthan gum-based microspheres and hydrogels, useful for targeted colorectal release of omega-3 polyunsaturated fatty acids (PUFAs), were successfully prepared and characterized. In particular, the microsphere size, as well as the high hydrogel swelling degree at pH 7.4, and the omega-3 PUFA loading efficiency of both the materials suggested their suitability for colorectal delivery. Moreover, the antioxidant efficiency of the xanthan gum based materials suggests their ability to protect the omega-PUFA cargo. We demonstrated that α-linolenic acid (ALA 18:3ω-3) carried by the materials increased significantly its ability to reduce colorectal cancer cell growth in vitro. On the contrary, docosahexaenoic acid (DHA, 22:6ω-3) enclosed in the hydrogel formulation did not enhance its already high anti-neoplastic potential. The improved anti-neoplastic efficacy of ALA enclosed in both the xanthan gum-based formulations further supports the hypothesis of a potential use of this omega-3 PUFA as a suitable and more sustainable alternative to the fish-derived DHA. |
