Given the vital role of vasculature in solid tumors, the potential of vascular disrupting therapy in the treatment of triple-negative breast cancer (TNBC) is promising. In this study, we prepared the acid-sensitive liposome PPD/CA4P/Lip-Rap loaded with the vascular disrupting agent CA4P and the anti-angiogenic drug rapamycin (Rap) to explore the potential of the vascular disrupting strategy in TNBC. PPD/CA4P/Lip-Rap was characterized by 1H NMR, dynamic light scattering, and transmission electron microscopy. Its drug loading and acid sensitivity were determined. The particle size of PPD/CA4P/Lip-Rap is 161.53 ± 1.89 nm, the zeta potential is -20.03 ± 0.9 mV and it demonstrated good drug release on acidic sensitivity responses. CCK-8 experiments proved that Rap can enhance the ability of CA4P to destroy tumor vascular endothelial cells. Rap can kill marginal residual tumor cells, suppress tumor recurrence. Nanocarriers can further enhance the therapeutic effect. Western blot (WB) showed that Rap decreased the expression of hypoxia-inducible factor-1
