Area of Science:

  • Oncology
  • Medicinal Chemistry
  • Biotechnology
  • Polymer Science

Background:

  • Prodrugs are crucial for targeted delivery of cytotoxic agents in cancer therapy.
  • Current prodrug strategies exhibit diversity in targeting, activation, and physicochemical properties.
  • Macromolecular prodrugs, including antibody-drug conjugates and polymer-drug conjugates, are a significant trend.

Purpose of the Study:

  • To provide a unified perspective on cancer-targeted prodrugs.
  • To highlight novel prodrug concepts emerging from recombinant technology.
  • To explore conditional targeting strategies for enhanced specificity in cancer treatment.

Main Methods:

  • Review of existing literature on cancer-targeted prodrugs.
  • Analysis of recombinant technologies, exemplified by engineered anthrax toxin.
  • Exploration of structural complementation for conditional and bispecific targeting.

Main Results:

  • Recombinant 'prodrugs' demonstrate potential for high biological specificity via conditional targeting.
  • Engineered anthrax toxin utilizes structural complementation for conditional targeting of multiple markers.
  • Complementing systems can be adapted for bispecific enzyme activation of low-molecular-weight prodrugs.

Conclusions:

  • Prodrugs, integrating medicinal chemistry, polymer science, and recombinant technology, are key to tailored cancer therapies.
  • Conditional targeting strategies offer precise approaches to attack complex molecular phenotypes in cancer.
  • The future of prodrug development lies in leveraging interdisciplinary strengths for advanced cancer treatment.

Targeted Cancer Therapies02:57

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...

Prodrugs

Prodrugs are a class of pharmaceutical compounds that undergo a biotransformation process within the body to be converted into a pharmacologically active drug. Prodrugs are designed to improve the therapeutic properties of the parent drug, such as enhancing bioavailability, increasing stability, or reducing toxicity. The concept of prodrugs revolves around modifying the chemical structure of the original drug to make it more effective or convenient for administration.

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.

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...

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...
