Abstract

Insights

Molecular targeted anticancer drugs offer promise but cause organ damage and side effects like hand-foot syndrome. Pharmaceutical toxicology research is crucial to understand and prevent these toxicities for better cancer treatment.

Area of Science:

  • Oncology
  • Pharmacology
  • Toxicology

Background:

  • Traditional chemotherapy has limitations in effectiveness and high adverse reactions.
  • Molecular targeted anticancer drugs represent a rapidly developing area in cancer treatment.
  • Current targeted therapies can cause significant organ damage (heart, liver, lung) and side effects (e.g., hand-foot syndrome).

Purpose of the Study:

  • To highlight the critical need for pharmaceutical toxicology research in evaluating molecular targeted anticancer drugs.
  • To investigate the toxicity profiles of novel targeted anticancer agents.
  • To explore mechanisms underlying drug-induced organ damage and adverse effects.

Main Methods:

  • Review of current literature on targeted anticancer drug toxicities.
  • Analysis of preclinical and clinical data on adverse events.
  • Identification of key toxicological pathways and biomarkers.

Main Results:

  • Molecular targeted drugs, while effective, exhibit specific organ toxicities.
  • Adverse effects such as hand-foot syndrome are common and limit clinical use.
  • Understanding toxicity mechanisms is essential for therapeutic development.

Conclusions:

  • Targeted anticancer drug development necessitates thorough toxicological evaluation.
  • Further research into toxicity mechanisms and prevention strategies is critical.
  • Mitigating adverse effects will enhance the clinical application of targeted cancer therapies.

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...

Drug Toxicity: Dose-Dependent Reactions

Drug toxicities can be stratified into pharmacological, pathological, or genotoxic based on their mechanisms. The incidence and severity of these toxicities generally increase with the drug's concentration in the body and exposure time.Pharmacological toxicity is evident when the therapeutic effects of drugs overshoot into adverse reactions in a predictable, dose-dependent manner. Central nervous system (CNS) depression from barbiturates is a classic example, with effects escalating from...

Pharmacogenetics of Drug Targets: β₂-Adrenergic Receptors, Apo E, Thymidylate Synthase

Genetic polymorphisms in drug targets have emerged as critical determinants of interindividual variability in drug response and toxicity. Pharmacogenomic investigations increasingly focus on identifying these variations to personalize and optimize therapeutic interventions. A drug target may be a receptor, enzyme, or signaling protein involved in pharmacologic responses or disease-related pathways. While early pharmacogenetic studies focused primarily on drug metabolism, current research...

Toxic Reactions: Overview01:26

Toxic Reactions: Overview

When toxic substances penetrate the human body, they disseminate to various tissues, undergoing metabolic changes. This process yields reactive metabolites that may covalently bind with specific target molecules, resulting in toxicity.
Toxicity falls into two primary categories: local and systemic.
Local toxicity appears at the exposure site, such as protein denaturation caused by caustic substances.
In contrast, systemic toxicity requires the toxic agent's absorption and distribution,...

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...
