Insights

Cisplatin and related anticancer drugs primarily target DNA but also interact with proteins, contributing to both therapeutic effects and side effects. This review examines these platinum-drug protein interactions.

Area of Science:

  • Biochemistry
  • Pharmacology
  • Cancer Research

Background:

  • Cisplatin and its analogs are crucial anticancer agents that exert cytotoxic effects through DNA binding.
  • The adverse side effects of platinum-based chemotherapy are often associated with platinum interactions with cellular proteins and peptides.
  • Protein interactions are the primary mechanism of action for certain other classes of anticancer drugs.

Purpose of the Study:

  • To review known interactions between cisplatin and related platinum compounds with proteins and biologically relevant peptides.
  • To emphasize the structural and reactivity aspects of these platinum-drug-protein interactions.

Main Methods:

  • Literature review of existing studies on cisplatin and related compounds.
  • Analysis of structural data and reactivity profiles of platinum-drug-protein adducts.

Main Results:

  • Cisplatin and its congeners interact with various proteins and peptides, influencing their function.
  • These interactions are implicated in both the therapeutic efficacy and the toxic side effects of platinum-based chemotherapy.
  • Understanding these interactions provides insights into drug mechanisms and potential strategies for mitigating toxicity.

Conclusions:

  • Platinum-drug interactions with proteins are a significant factor in cancer chemotherapy, affecting both efficacy and toxicity.
  • Further investigation into the structural and reactivity aspects of these interactions is crucial for developing improved platinum-based anticancer therapies.

Pharmacokinetics: Drug–Drug Interactions

Drug interactions occur when the pharmacological effect of one drug is altered by another substance, either enhancing or diminishing its activity. The drug whose activity is altered is known as the object drug, and the substance causing the alteration is called the agent drug or the precipitant. The net effects of these interactions are mostly undesirable, leading to decreased effectiveness or increased adverse effects. In rare cases, interactions can be beneficial, such as the enhanced...
Drug toxicity: Drug–Drug Interaction01:30

Drug toxicity: Drug–Drug Interaction

Drug–drug interactions can precipitate toxicity through multiple mechanisms. Absorption interactions alter how drugs enter the body, exemplified when ranitidine increases the absorption of basic drugs, while cholestyramine decreases the levels of propranolol. Protein binding interactions occur when drugs share the same binding sites on plasma proteins. Drugs like aspirin and warfarin, when bound in excess, can lead to increased free drug concentrations, enhancing the potential for...
Factors Affecting Protein-Drug Binding: Drug Interactions01:23

Factors Affecting Protein-Drug Binding: Drug Interactions

Drug interactions are a critical aspect of pharmacology and can occur when two or more drugs compete for the same binding site. This competition can result in one drug displacing another, altering the effect of the displaced drug. Drug interactions are complex processes that rely heavily on how much of the displacer drug is present and how strongly it can bind to the same sites as the displaced drug.
Displacement interactions can have varying outcomes, ranging from toxicity to virtually...
Combination Therapies and Personalized Medicine02:50

Combination Therapies and Personalized Medicine

Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...
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...
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...
