제목 Synergistic anti-tumor activity of paclitaxel-incorporated conjugated linoleic acid-coupled poloxamer thermosensitive hydrogel in vitro and in vivo
초록 Local delivery of anti-tumor drugs provides a high local concentration and decreases the incidence of side effects commonly observed with systemic therapy. In this study, we prepared a novel thermosensitive conjugated linoleic acid-coupled poloxamer hydrogel for local delivery of paclitaxel. To evaluate the anti-tumor activity of the PTX-incorporated CLA-coupled poloxamer hydrogel in vivo, formulations were injected subcutaneously into tumor-bearing mice. The PTX-incorporated CLA-coupled poloxamer hydrogel showed excellent anti-tumor activity in vivo inducing stronger cell cycle arrest and apoptosis. These results were attributed to the synergistic effect of the anti-tumor property of PTX with released CLA from the CLA-coupled poloxamer and the enhanced solubility of PTX resulting from the micellar property of the CLA-coupled poloxamer. The CLA-coupled poloxamer designed in this study has great potential as an effective injectable carrier of PTX.
