Objective: we work on the designed synthesis of a tumor-responsive nanoformulated triptolide (Nf-Trip)for HCC targeted therapy, which is delivered specifically to tumor cells.Methods: Nf-Trip is composed of natural triptolide and two polymers synthesized from generally recognized as safe (GRAS) materials;One polymer is pluronic F127 esterified with folic acid and the other is a synthetic 10-mer of aspartic acid with an octadecylamine tail and ionizable imidazole side chains for pH sensitivity.
