Abstract:
A novel supramolecular hybrid material ZIF-8@DOX@WP6@G constructed from the host-guest complexation between carboxylated pillar[6]arene (WP6) and a galactose derivative (G), and doxorubicin (DOX)-loaded ZIF-8 has been synthesized for targeted drug delivery. The results showed that ZIF-8@DOX@WP6@G not only maintained the pH-sensitive drug release properties of ZIF-8 but also exhibited excellent water dispersibility and selective toxicity for hepatoma cancer cells due to the assembly of WP6 and G. The strategy used in this study opens up a new avenue for constructing multifunctional supramolecular hybrid materials for therapeutic applications in cancer treatment.

Enteral delivery involves administering drugs directly through swallowing, sublingual placement, or buccal application. Orally administered drugs predominantly navigate the...
Drug Delivery: Enteral Route
Drug Delivery: Parenteral Route
There are three primary parenteral routes: intravenous (IV), intramuscular (IM), and subcutaneous (SC). The IV route introduces the drug directly into the bloodstream, ensuring immediate action. The IM route...
Targets for Drug Action: Overview
Receptors are either membrane-spanning or intracellular proteins, which upon binding a ligand, get activated and transmit the signal downstream to elicit a response. Drugs bind receptors, either mimicking the action of endogenous ligands or blocking the receptor activity to bring about a modified response. Nearly 35% of approved drugs target the G...
Drug Delivery: Miscellaneous Routes
Oral inhalation and nasal sprays swiftly transfer drugs across the respiratory epithelium's mucosal layer. Inhaled glucocorticoids and bronchodilators directly target lung conditions such as asthma, while fluticasone nasal spray mitigates allergic rhinitis.
