Ovarian cancer, a highly lethal form of gynecological cancer globally, has witnessed notable advancements in its treatment through the integration of nanotechnology and immunotherapy. Here, we designed a novel astragalus polysaccharide vector (PDA), encapsulating podophyllotoxin (PPT), and modifying methotrexate (DSPE-PEG-MTX) on its surface for targeting ovarian cancer cells with high folate receptor expression. We prepared novel MTX-modified PPT-loaded astragalus polysaccharide micelles (MTX-PPT-micelles) by dialysis method and evaluated their characterization, stability, safety and targeting ability.

Hence, herein, an LGZG oral solution was developed for alleviating MASLD. Additionally, the potential mechanisms underlying LGZG-mediated MASLD mitigation were explored.

In this work, a liposome drug delivery system (HA/P/BAI-lip) incorporated with baicalein and modified by PHMG and HA was prepared. Several characterizations were conducted to examine the physical properties of liposome.

Resveratrol, a star molecule in natural polyphenols, has been widely reported to have physiological activities such as anti-aging, anti-inflammatory, antioxidant, and neuroprotection. However, its poor water solubility, rapid metabolism, low bioavailability and poor targeting ability, which limits its application.

Several studies and clinical trials have demonstrated that resveratrol (Res) and salidroside (Sal) are not only biologically safe but also influence AD biomarker trajectories. However, their clinical applications have been quite limited due to poor specificity, low solubility, and insufficient blood-brain barrier (BBB) penetration.

In recent years, the treatment of tumor with nano-targeted agents has become a potential research focus. In this study, a new type of short cell-penetrating peptide RPV-modified paclitaxel plus schisandrin B liposomes were constructed to disrupt VM channels, angiogenesis, proliferation and migration for the treatment of ovarian cancer.
