Target-homing drug delivery systems offer promising cancer therapy by exploiting tumor-specific recognition sites. Further research into novel sites and targeting moieties will enhance chemotherapeutics.
Area of Science:
- Oncology
- Nanotechnology
- Pharmacology
Background:
- Target-homing drug delivery systems are crucial for advanced cancer therapy.
- These systems enhance anticancer drug efficacy by improving solubility and site-specific distribution.
- Targeting strategies leverage differences between cancerous and normal tissues, such as low pH and receptor overexpression.
Purpose of the Study:
- To identify and review tumor-specific recognition sites for developing targeted drug delivery systems.
- To optimize the design of drug delivery systems for enhanced antitumor effects.
Main Methods:
- Literature review of cancer-specific recognition sites and abnormal tumor characteristics.
- Compilation of data on tumor microenvironment (pH, glutathione) and cell surface receptors.
- Analysis of tumor cell organelle dysregulation (nuclear, endoplasmic reticulum).
Main Results:
- Identified various recognition sites in tumor tissues, cells, and organelles.
- Highlighted the design of drug delivery systems that home in on these sites.
- Demonstrated the potential of targeted systems to improve drug delivery for cancer treatment.
Conclusions:
- Targeted drug delivery systems represent a significant advancement in tumor chemotherapy.
- Continued research on novel recognition sites and targeting moieties is essential.
- This will facilitate the clinical application of improved chemotherapeutics.

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...
