Insights

Drug-metabolising enzymes (DMEs) in tumors can affect cancer drug efficacy. Understanding tumor drug metabolism is key for improving cancer therapy and developing new treatments.

Area of Science:

  • Pharmacology
  • Oncology
  • Biochemistry

Background:

  • Drug-metabolising enzymes (DMEs) are found in tumors and can alter anticancer drugs.
  • Tumor drug metabolism presents a dual role: it can cause resistance or enable effective therapy.

Purpose of the Study:

  • To review the classes of DMEs, their substrates, and distribution in various cancers.
  • To discuss the limitations of current research and the potential of DMEs in cancer treatment.

Main Methods:

  • Literature review of preclinical and clinical studies on tumor drug metabolism.
  • Analysis of DME roles in drug resistance, prodrug activation, and therapeutic response prediction.

Main Results:

  • DMEs significantly influence the efficacy and toxicity of antineoplastic agents within tumors.
  • Current studies have limitations in fully elucidating the clinical impact of tumoral DMEs.

Conclusions:

  • Tumor DMEs are critical for cancer therapy, impacting drug response and resistance.
  • Further large-scale prospective studies and technological advancements are needed to harness DMEs for optimized cancer treatment strategies.

Pharmacogenetics of Drug Metabolism: Overview

Genetic polymorphism in drug metabolism is crucial to the inter-individual variability observed in drug responses. Drug metabolism primarily involves the chemical modification of drugs and other xenobiotics to enhance their elimination by increasing their polarity. Two main classes of enzymes mediate this biotransformation process: Phase I enzymes, primarily cytochrome P450s, catalyze oxidation and reduction reactions, while other enzymes, such as esterases, mediate hydrolysis, and Phase II...

Therapeutic Drug Monitoring: Affecting Factors

Therapeutic Drug Monitoring (TDM) is the clinical practice of measuring specific drug levels in a patient's blood or body tissues to manage and optimize therapy. TDM is crucial for drugs with narrow therapeutic windows, like warfarin and phenytoin, where incorrect doses can lead to treatment failure or severe side effects. This monitoring ensures the dosage administered is within a safe and effective range. The factors affecting therapeutic drug monitoring include:Patient-Specific Factors:a.
Drug Biotransformation: Overview01:28

Drug Biotransformation: Overview

Biotransformation, also known as drug metabolism, is a vital physiological process that chemically alters drugs, facilitating their elimination from the body and terminating their action. This process involves two main phases: phase I and phase II reactions. Phase I reactions, including oxidation, reduction, and hydrolysis, introduce or unmask polar functional groups on the drug molecule, thereby increasing its water solubility. By enhancing water solubility, the drug becomes more hydrophilic...

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...

Factors Affecting Drug Biotransformation: Biological

Biological factors significantly impact drug metabolism, influencing drug clearance, efficacy, and potential toxicity.
Species differences: Variations in enzyme systems across species can cause disparities in drug metabolism. For instance, humans may metabolize certain drugs faster than rodents, altering therapeutic effects.
Strain differences: Genetic variations within a species can result in differing enzyme activity, impacting drug response and toxicity. For example, some mouse strains may...

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...
