Abstract:
This review presents molecular targeting approaches in anticancer drug delivery systems (DDS) and identifies new developments in these systems. Targeting approaches include passive targeting (enhanced permeability and retention effect), targeting specific tumor conditions, topical delivery and active targeting, namely, targeting organs, cells, intracellular organelles and molecules, sandwich targeting, promoter targeting, indirect targeting and targeting by external stimuli. A novel advanced proapoptotic anticancer DDS that utilizes several molecular targets will be considered. Experimental data suggest that this DDS can simultaneously: (1) induce cell death, (2) prevent adverse effects on healthy tissues; (3) suppress and prevent multidrug resistance; and (4) inhibit cellular antiapoptotic defense.
Insights
This review explores advanced molecular targeting strategies for anticancer drug delivery systems (DDS). A novel proapoptotic DDS shows promise in simultaneously inducing cancer cell death and preventing drug resistance.
Area of Science:
- Oncology
- Nanotechnology
- Pharmacology
Background:
- Anticancer drug delivery systems (DDS) are crucial for effective cancer treatment.
- Traditional chemotherapy faces challenges like systemic toxicity and multidrug resistance.
- Molecular targeting offers a strategy to enhance drug efficacy and reduce side effects.
Purpose of the Study:
- To review current molecular targeting approaches in anticancer DDS.
- To identify novel developments and a new proapoptotic DDS.
- To evaluate the potential of advanced DDS in cancer therapy.
Main Methods:
- Comprehensive literature review of molecular targeting strategies in DDS.
- Analysis of passive targeting (e.g., enhanced permeability and retention effect).
- Examination of active targeting methods (organelles, cells, molecules) and novel approaches.
Main Results:
- Various targeting strategies discussed, including passive, active, and stimuli-responsive approaches.
- A novel proapoptotic DDS is presented, utilizing multiple molecular targets.
- Experimental data indicate this DDS can induce apoptosis, minimize healthy tissue damage, overcome multidrug resistance, and inhibit antiapoptotic mechanisms.
Conclusions:
- Molecular targeting significantly enhances the precision and efficacy of anticancer DDS.
- The novel proapoptotic DDS demonstrates multi-pronged therapeutic potential.
- Advanced DDS hold promise for improved cancer treatment outcomes with reduced toxicity.

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...
