Abstract

Insights

Liver-targeted prodrugs enhance treatment efficacy and reduce side effects for liver diseases by utilizing passive and active targeting strategies. Future research should optimize drug design and targeting efficiency for clinical success.

Area of Science:

  • Pharmacology
  • Drug Delivery Systems
  • Hepatology

Background:

  • The liver is a primary drug target, but liver diseases like NAFLD and HCC pose global health challenges.
  • Current treatments lack specificity, leading to suboptimal efficacy and increased side effects.
  • Non-alcoholic fatty liver disease (NAFLD) and hepatocellular carcinoma (HCC) are significant health concerns.

Purpose of the Study:

  • To review advancements in liver-targeted prodrug design.
  • To focus on passive and active targeting strategies for improved therapeutic outcomes.
  • To offer insights into developing effective liver-targeted therapies.

Main Methods:

  • Systematic literature search across major scientific databases (PubMed, Web of Science, etc.).
  • Focus on targeting mechanisms including the Enhanced Permeability and Retention (EPR) effect and tumor microenvironment.
  • Inclusion of active targeting via specific transporters and receptors.

Main Results:

  • Passive targeting leverages the EPR effect and tumor characteristics for drug enrichment.
  • Active targeting utilizes specific ligands to bind liver surface receptors for precise delivery.
  • Successful examples include small molecules, peptides, antibodies, and nanoparticles as carriers.

Conclusions:

  • Liver-targeted prodrugs significantly improve treatment efficacy and reduce side effects.
  • Future work requires balancing targeting strategies and optimizing drug design for clinical use.
  • Developing novel targeting molecules and understanding liver-specific receptors are key.

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.

Drug Biotransformation: Overview01:16

Drug Biotransformation: Overview

Pharmaceutical substances known as xenobiotics are predominantly lipophilic and nonionized. This enables them to permeate lipid bilayers, such as cell membranes, and interact with intracellular target receptors. Lipophilic drugs have an advantage in crossing biological barriers and reaching their intended sites of action. However, lipophilic drugs often have a restricted capacity for renal expulsion or elimination from the body. When these drugs enter the kidneys and undergo glomerular...

Physiological Pharmacokinetic Models: Incorporating Hepatic Transporter-Mediated Clearance

Drug transporters are critical in drug absorption, distribution, and excretion processes. They should be included in physiological-based pharmacokinetic (PBPK) models, which help predict human drug disposition. However, predicting this is challenging during drug development, especially when liver transport is involved. However, with a realistic representation of body transport processes, an accurate model may be possible.

Carrier-Mediated Transport01:06

Carrier-Mediated Transport

Carrier-mediated transport is a pivotal process in drug absorption, particularly for lipid-insoluble drugs, and encompasses facilitated diffusion and active transport. Facilitated diffusion allows drugs to move along their concentration gradient without energy expenditure, while active transport utilizes ATP to drive drug movement against this gradient.
Active transport involves two types of membrane-spanning transporters: uptake and efflux. Uptake transporters are expressed in the small...

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...

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...
