Abstract:
The vast majority of anticancer drugs in clinical use are limited by systemic host toxicity due to their non-specific side effects. These shortcomings have led to the development of tumour specific drugs which target a single-deregulated pathway or over expressed receptor in cancer cells. Whilst this approach has achieved clinical success, we have also learnt that targeting a single entity in cancer is rarely curative due to the large number of deregulated pathways, receptors and kinases which are also present, in addition to the target. An attractive alternative to improve targeting would be to harness the already established activity of known anticancer drugs by attaching them to a molecule that is transported into cancer cells via a selective transport system. One possibility for this approach is the polyamine pathway. This review provides a brief overview of the polyamine pathway and how, over the years, it has proved an exciting target for the development of novel anticancer agents. However, the focus of this article will be on the properties of the polyamine transport system and how these features could potentially be exploited to develop a novel and selective anticancer drug delivery system.
Insights
Targeting cancer cells specifically is challenging due to drug toxicity and tumor complexity. This review explores using the polyamine pathway for selective anticancer drug delivery, offering a promising alternative.
Area of Science:
- Oncology
- Pharmacology
- Molecular Biology
Background:
- Current anticancer drugs often cause systemic toxicity due to non-specific side effects.
- Targeting single pathways in cancer is insufficient for a cure due to pathway redundancy.
- The polyamine pathway presents a potential target for novel anticancer strategies.
Purpose of the Study:
- To review the polyamine pathway as a target for anticancer drug development.
- To explore the exploitation of the polyamine transport system for selective cancer drug delivery.
Main Methods:
- Literature review of the polyamine pathway and its role in cancer.
- Analysis of the polyamine transport system's properties.
- Discussion of potential applications in drug delivery systems.
Main Results:
- The polyamine pathway has historically been a target for anticancer agent development.
- The polyamine transport system exhibits characteristics amenable to targeted drug delivery.
- Exploiting this system could lead to novel, selective anticancer therapies.
Conclusions:
- The polyamine pathway offers a viable target for developing new anticancer drugs.
- The polyamine transport system's selectivity can be leveraged for targeted drug delivery.
- This approach holds promise for improving the efficacy and reducing the toxicity of cancer treatments.

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...
