Insights

Metal-based anticancer drugs like cisplatin show promise but face challenges such as poor solubility. Current research focuses on advanced drug delivery systems, not new drug synthesis, to improve metallodrug efficacy in cancer therapy.

Area of Science:

  • Medicinal Chemistry
  • Oncology
  • Materials Science

Background:

  • The discovery of cisplatin's antiproliferative activity spurred the development of metal-based drugs for cancer treatment.
  • Numerous metal complexes have undergone preclinical and clinical evaluation, advancing metallodrug chemistry.
  • Despite progress, challenges like poor water solubility and limited pharmacological efficacy hinder clinical application of these metallodrugs.

Purpose of the Study:

  • To address the limitations of existing metal-based anticancer drugs.
  • To explore advanced drug delivery strategies as a solution to enhance metallodrug performance.
  • To shift focus from synthesizing new drugs to optimizing delivery of current metallodrugs.

Main Methods:

  • Review of various drug delivery systems for metallodrugs.
  • Analysis of strategies including prodrug approaches.
  • Evaluation of ligand design modifications.
  • Investigation of nanocarrier-based delivery systems.

Main Results:

  • Drug delivery systems offer a viable solution to overcome metallodrug deficiencies.
  • Prodrugs, ligand design, and nanocarriers can improve solubility and pharmacological profiles.
  • These strategies enhance the overall performance of metal-based anticancer agents.

Conclusions:

  • Optimizing drug delivery is crucial for the clinical success of metallodrugs.
  • Advanced delivery systems represent a promising avenue for improving cancer therapy.
  • Future efforts should prioritize delivery strategies to maximize the potential of metal-based oncology drugs.

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...
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 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.
Drug Delivery: Overview01:16

Drug Delivery: Overview

The selection of a drug's delivery route depends upon its physicochemical properties, including lipid or water solubility and ionization, as well as the therapeutic requirement, such as immediate or sustained effect. These routes can be divided into three primary categories: enteral, parenteral, and topical.
Enteral delivery involves administering drugs directly through swallowing, sublingual placement, or buccal application. Orally administered drugs predominantly navigate the gastrointestinal...
Treatment Resistent Cancers02:56

Treatment Resistent Cancers

Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...
