PTX-HSN是一种高效纳米系统，具有较高耐受剂量，可将PTX递送至卵巢癌并增强主动肿瘤靶向性。此研究中所有体内实验均通过美迪西进行

Paclitaxel-loaded hyaluronan solid nanoemulsions (PTX-HSNs) were successfully fabricated for the delivery of PTX to improve ovarian cancer treatment via active tumor targeting. The in vivo toxicity, in vivo antitumor effects, and pharmacokinetics of PTX-HSNs and Taxol were evaluated in nude mice and rats. PTX-HSN is a highly effective nanosystem with a high maximum tolerated dose (MTD) for delivering PTX to ovarian cancers characterized by CD44 overexpression, enhanced active tumor targeting, and low toxicity. All in vivo experiments were conducted with the approval of the Association for Assessment and Accreditation of Laboratory Animal Care (AAALAC) International (tested at Medicilon/MPI Preclinical Research).
