Melittin (MEL) is a 26-amino acid polypeptide with a variety of pharmacological and toxicological effects, which include strong surface activity on cell lipid membranes, hemolytic activity, and potential anti-tumor properties. However, the clinical application of melittin is restricted due to its severe hemolytic activity. Different nanocarrier systems have been developed to achieve stable loading, side effects shielding, and tumor-targeted delivery, such as liposomes, cationic polymers, lipodisks, etc. In addition, MEL can be modified on nano drugs as a non-selective cytolytic peptide to enhance cellular uptake and endosomal/lysosomal escape. In this review, we discuss recent advances in MEL's nano-delivery systems and MEL-modified nano drug carriers for cancer therapy.

Chemotherapy is the primary treatment option for pancreatic cancer, although nanocarrier-based drug delivery systems often struggle with multiple physiological barriers, limiting their therapeutic efficacy. Here, we developed a pH/reactive oxygen species (ROS) dual-sensitive self-adaptive nanocarrier (DAT) encapsulating camptothecin (CPT), an analog of the pancreatic chemotherapeutic drug irinotecan (CPT-11), to enhance chemotherapy outcomes in orthotopic pancreatic cancer by addressing multiple physiological barriers. The nanocarrier features a peripherally positively charged arginine (Arg) residue on DAT and is masked with an acid-labile 2,3-dimethylmaleic anhydride (DA) to improve circulation time.

Poly(butyl cyanoacrylate) (PBCA) nanoparticles have numerous applications, including drug and gene delivery, molecular imaging, and cancer therapy. To uncover the molecular mechanisms underlying their interactions with cell membranes, we utilized a Langmuir monolayer as a model membrane system. This approach enabled us to investigate the processes of penetration and reorganization of PBCA nanoparticles when deposited in a phospholipid monolayer subphase.

CY1-4, 9-nitropyridine [2',3':4,5] pyrimido [1,2-α] indole -5,11- dione, is an indoleamine 2,3-dioxygenase (IDO) inhibitor and a poorly water-soluble substance. It is very important to increase the solubility of CY1-4 to improve its bioavailability and therapeutic effect. In this study, the mesoporous silica nano-skeleton carrier material Sylysia was selected as the carrier to load CY1-4, and then the CY1-4 nano-skeleton drug delivery system (MSNM@CY1-4) was prepared by coating the hydrophilic polymer material Hydroxypropyl methylcellulose (HPMC) and the lipid material Distearoylphosphatidyl-ethanolamine-poly(ethylene glycol) (DSPE-PEG) to improve the anti-tumor effect of CY1-4.

This study aims to assess the neuroprotective effects of the methanolic extract of against oxidative stress and cell death induced by neurotoxins MPP in SH-SY5Y cells. Briefly, the methanolic extract of decreased the cytotoxicity of MPP in SH-SY5Y cells. Treatment with extract at a concentration of 400 µg/ml resulted in a notable decrease in cell death, particularly in MPP -induced cells.

The treatment of tumors continues to be significantly challenging. The presence of multiple modalities, including surgery, radiation, chemotherapy and immunotherapy, the therapeutic outcomes remain limited and are often associated with adverse effects and inconsistent efficacy across cancer types. Recent studies have highlighted the potential of active components from traditional Chinese medicine (TCM) for their anti-cancer properties, which are attributable to multi-targeted mechanisms and broad pharmacological actions.
