Insights

Targeted drug delivery utilizes unique tumor cell markers to concentrate therapies. Nanoparticles targeting tumor vasculature offer enhanced efficacy and reduced side effects for cancer treatment.

Area of Science:

  • Biomedical Engineering
  • Nanotechnology
  • Oncology

Background:

  • Tumor cells express unique molecular markers absent or low in normal cells.
  • Tumor vasculature markers are accessible targets for circulating therapeutic agents.

Purpose of the Study:

  • To review advances in targeted drug delivery using molecular markers on tumor vasculature.
  • To highlight the use of nanoparticles as a delivery vehicle for cancer therapeutics.

Main Methods:

  • Review of recent scientific literature on targeted drug delivery systems.
  • Focus on nanoparticle-based strategies targeting tumor vasculature markers.

Main Results:

  • Differential expression of molecular markers on tumor cells and vasculature enables targeted accumulation of drugs.
  • Nanoparticles can effectively target tumor-specific vascular markers.

Conclusions:

  • Targeted delivery concentrates drugs at the disease site, improving efficacy and reducing toxicity.
  • Nanoparticles targeting tumor vasculature represent a promising approach for enhanced cancer therapy.

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against specific...

Modified-Release Drug Delivery Systems: Site-Targeted

Site-targeted drug delivery systems enhance therapeutic efficacy while minimizing systemic toxicity and treatment costs. Unlike conventional methods, these systems ensure precise drug delivery, improving bioavailability and reducing side effects. Targeted drug delivery is classified into three levels. First-order targeting directs drugs to the capillary beds of specific organs or tissues. Second-order targets specific cell types, such as tumor cells, using receptor-mediated interactions.

Site-Targeted Drug Delivery Systems: Polymeric Carriers

Polymeric carriers enhance targeted drug delivery by increasing efficacy while minimizing off-target effects. These carriers comprise a biodegradable polymeric backbone integrated with functional elements that enable targeting, improve physicochemical properties, and regulate drug release.Targeting MechanismsThe targeting ability of polymeric carriers is mediated by a homing device, which is a molecular recognition component designed to selectively bind to specific tissues or cells. Monoclonal...
Targets for Drug Action: Overview01:26

Targets for Drug Action: Overview

Drugs target macromolecules to modify ongoing cellular processes. Primary drug targets include receptors, ion channels, transporters, and enzymes.
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...
Combination Therapies and Personalized Medicine02:50

Combination Therapies and Personalized Medicine

Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...
