Chemoresistance encountered using conventional chemotherapy demands novel treatment approaches. Asplatin (Asp), a novel platinum (IV) prodrug designed to release cisplatin and aspirin in a reductive environment, has demonstrated high cytotoxicity at reduced drug resistance. Herein, we investigated the ability of green-synthesized nanocarriers to enhance Asp's efficacy.

, has been widely recognized for its medical applications. LC-ESI-TOF-MS identified 22 secondary metabolites including phenolics, flavonoids, and anthocyanidin glycosides among its total extract (LCTE). The study aimed to apply LCTE as a biogenic material for reducing and capping the silver nanoparticles (LC-AgNPs).

Article Synopsis
  • Carboplatin is effective against cancer but has significant side effects, prompting researchers to explore the use of nanoparticle formulations with frankincense extract to enhance its effectiveness.
  • The study developed nanoparticles (Cp@CS/BME NPs) that increased the uptake and cancer cell-killing ability of carboplatin, particularly in acidic tumor environments.
  • In vitro results showed these nanoparticles improve apoptosis in colorectal cancer cell lines by lowering anti-apoptotic genes and promoting pro-apoptotic gene expression, suggesting a more effective and safer chemotherapy approach.

Despite recent advancements in cancer therapies, challenges such as severe toxic effects, non-selective targeting, resistance to chemotherapy and radiotherapy, and recurrence of metastatic tumors persist. Consequently, there has been considerable effort to explore innovative anticancer compounds, particularly in immunotherapy, which offer the potential for enhanced biosafety and efficacy in cancer prevention and treatment. One such avenue of exploration involves the miRNA-34 (miR-34) family, known for its ability to inhibit tumorigenesis across various cancers.

This study presents properties of hydroethanolic extracts prepared from Pinot Noir (PN) grape pomace through conventional, ultrasound-assisted or solvothermal extraction. The components of the extracts were identified by HPLC. The total content of polyphenols, flavonoids, anthocyanins, and condensed tannins, as well as antioxidant activity and α-glucosidase inhibitory activity of extracts were evaluated using UV-vis spectroscopy.
