Abstract

Insights

Drug resistance to anaplastic lymphoma kinase (ALK) inhibitors is a major challenge in cancer treatment. This review explores resistance mechanisms and structural modifications to develop next-generation ALK inhibitors.

Area of Science:

  • Oncology
  • Molecular Biology
  • Pharmacology

Background:

  • Anaplastic lymphoma kinase (ALK) gene rearrangements drive cancers like non-small cell lung cancer (NSCLC) and anaplastic large cell lymphoma (ALCL).
  • While ALK inhibitors like crizotinib have advanced treatment, acquired drug resistance remains a significant clinical challenge.
  • Overcoming resistance is crucial for improving patient outcomes and developing more effective therapies.

Purpose of the Study:

  • To review the mechanisms of drug resistance in anaplastic lymphoma kinase (ALK) inhibitors.
  • To discuss structural modifications and strategies aimed at overcoming ALK inhibitor resistance.
  • To provide insights for the development of next-generation ALK kinase inhibitors.

Main Methods:

  • Literature review using relevant scientific databases.
  • Screening and selection of studies based on content relevance and novelty.
  • Synthesis and analysis of selected literature to summarize findings.

Main Results:

  • ALK kinase composition and its role in cancer were reviewed.
  • Key resistance pathways associated with ALK inhibitors were identified.
  • Structural modifications and therapeutic strategies to overcome resistance were presented.

Conclusions:

  • This review consolidates current understanding of ALK inhibitor resistance pathways.
  • It highlights efforts in structural modification to combat resistance.
  • The findings aim to inspire the development of novel ALK inhibitors for improved cancer therapy.

Treatment Resistant Cancers02:56

Treatment Resistant 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...

Enzyme Inhibition01:30

Enzyme Inhibition

Inhibitors are molecules that reduce enzyme activity by binding to the enzyme. In a normally functioning cell, enzymes are regulated by a variety of inhibitors. Drugs and other toxins can also inhibit enzymes. Some inhibitors bind to the enzyme’s active site, while others inhibit enzymatic activity by binding to other sites on the protein structure.

Effect of Hepatic Disease on Pharmacokinetics: Active Drug, Metabolite and Fraction of Metabolized Drug01:14

Effect of Hepatic Disease on Pharmacokinetics: Active Drug, Metabolite and Fraction of Metabolized Drug

In pharmacotherapy, monitoring drug concentrations is paramount, especially for drugs whose therapeutic effects hinge on both the active compound and its metabolite. Hepatic impairment profoundly influences drug potency by altering liver function. If the drug is more potent than its metabolite, impaired liver function amplifies drug activity due to elevated drug concentration levels. Conversely, if the metabolite holds greater potency, diminished liver function diminishes drug activity by...

Drug Elimination by Renal Route: Tubular Reabsorption01:22

Drug Elimination by Renal Route: Tubular Reabsorption

During the process of renal excretion, as the glomerular filtrate progresses to the distal convoluted tubule (DCT), drugs that are highly permeable, lipophilic, and nonionized undergo passive reabsorption from the tubular fluid into the surrounding peritubular capillaries. This reabsorption process restricts their elimination through the kidneys. However, the majority of drugs are either weak acids or weak bases, and their ionization level is dependent on pH. By altering the pH of urine, the...

Nonlinear Pharmacokinetics: Role of Transporters01:27

Nonlinear Pharmacokinetics: Role of Transporters

A drug's nonlinear kinetics can be influenced by a diverse range of transporter proteins that serve as crucial players in drug distribution. These transporters, found within cells, can enhance or reduce local drug concentrations by facilitating the influx or efflux of drugs. For instance, the expression of xenobiotic transporters can be influenced by factors such as age and gender, potentially impacting the linearity of drug response.
Polymorphisms occurring in drug transporters can alter...

Effect of Hepatic Disease on Pharmacokinetics: Dose Adjustments Due to Hepatic Impairment01:08

Effect of Hepatic Disease on Pharmacokinetics: Dose Adjustments Due to Hepatic Impairment

Hepatic impairment, characterized by decreased liver function, does not uniformly mandate adjustments in drug dosage. Whether dosage modifications are necessary depends on various factors related to the drug's metabolism and elimination pathways. If a drug is primarily excreted via the kidneys and bypasses significant hepatic processing, if it undergoes minimal metabolic transformation in the liver, or if it is volatile and primarily expelled through the lungs, dose adjustments may not be...
