Summary
Mitochondria are vital cell centers, and their interaction with drugs is crucial for both toxicity and therapy. Understanding drug effects on mitochondria opens new therapeutic avenues.
Area of Science:
- Mitochondrial biology
- Pharmacology
- Toxicology
Background:
- Mitochondria are central to cellular energy metabolism, homeostasis, and signaling pathways.
- Drug interactions with mitochondria are often overlooked in toxicology and therapeutic development.
- Mitochondrial functions are increasingly recognized as targets for therapeutic intervention.
Purpose of the Study:
- To highlight the critical role of mitochondria in pharmacology and toxicology.
- To explore the therapeutic potential of modulating mitochondrial activity.
- To review drug targets within mitochondria and their clinical relevance.
Main Methods:
- Review of existing literature on drug-mitochondria interactions.
- Analysis of mechanisms underlying mitochondrial toxicity.
- Examination of therapeutic strategies targeting mitochondria.
Main Results:
- Several drug classes exhibit mitochondrial toxicity via diverse mechanisms, including DNA polymerase-gamma inhibition and electron transport chain disruption.
- Drugs can disrupt mitochondrial ion homeostasis and the permeability transition pore.

01:46Electron Transport Chain: Complex I and II
The mitochondrial electron transport chain (ETC) is the main energy generation system in the eukaryotic cells. However, mitochondria also produce cytotoxic reactive oxygen species (ROS) due to the large electron flow during oxidative phosphorylation. While Complex I is one of the primary sources of superoxide radicals, ROS production by Complex II is uncommon and may only be observed in cancer cells with mutated complexes.
ROS generation is regulated and maintained at moderate levels necessary...

01:37Mitochondria
Mitochondria are eukaryotic cellular organelles that are known to produce energy through a process called oxidative phosphorylation. Besides their primary function, mitochondria are involved in various cellular processes, including cell growth, differentiation, signaling, metabolism, and senescence. Age-related changes cause a decline in mitochondrial quality and integrity due to increased mitochondrial mutations and oxidative damage. Thus, aging can severely impact mitochondrial functions,...
01:19Translocation of Proteins into the Mitochondria
Mitochondrial precursors are translocated to the internal subcompartments via independent mechanisms involving distinct protein machineries called translocases.
Sorting of outer membrane proteins:
Mitochondrial outer membrane proteins are of two types: the transmembrane, beta-barrel porins, and the membrane-anchored, alpha-helical proteins. Beta-barrel porin precursors are translocated by the TOM complex and inserted into the outer mitochondrial membrane by the SAM complex. In contrast,...

01:30Peroxisomes and Mitochondria
Peroxisomes and mitochondria are two important oxygen-utilizing organelles in eukaryotic cells. Mitochondria carry out cellular respiration—the process that converts energy from food into ATP. Peroxisomes carry out a variety of functions, primarily breaking down different substances, such as fatty acids.
The peroxisome is a single membrane-bound cellular organelle that can perform several different functions, including lipid metabolism and chemical detoxification. The enzymes within peroxisomes...

01:16Drug 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...
01:28Drug 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...
