Thiosemicarbazone metal complexes target cellular mitochondria, inducing apoptosis for novel cancer treatments. This review details their structures and anticancer mechanisms via mitochondrial pathways.

Area of Science:

  • Biochemistry and Molecular Biology
  • Pharmacology and Toxicology
  • Cancer Research

Background:

  • Mitochondria are crucial for cellular energy, apoptosis, and metabolic regulation, making them key targets for cancer therapy.
  • Thiosemicarbazone metal complexes are emerging as promising anticancer agents by targeting mitochondrial function.
  • Disrupting mitochondrial membrane potential initiates apoptosis, leading to cancer cell death.

Purpose of the Study:

  • To review the structural diversity of thiosemicarbazone metal complexes.
  • To explore the anticancer mechanisms of these complexes that target mitochondrial pathways.
  • To highlight their potential as novel therapeutic agents for cancer treatment.

Main Methods:

  • Literature review of thiosemicarbazone metal complexes.
  • Analysis of structural variations in metal complexes (Fe(III), Cu(II), Ni(II), Zn(II), Ga(III), Pb(II), Au(III), Ir(III)).
  • Examination of mechanisms targeting mitochondrial pathways, including membrane potential disruption and apoptosis induction.

Main Results:

  • Thiosemicarbazone metal complexes exhibit significant structural diversity.
  • These complexes effectively target mitochondria, leading to a reduction in mitochondrial membrane potential.
  • The disruption of mitochondrial membrane potential triggers apoptosis in cancer cells.

Conclusions:

  • Thiosemicarbazone metal complexes represent a promising class of anticancer agents.
  • Their efficacy is linked to their ability to target and disrupt mitochondrial function, inducing apoptosis.
  • Further research into these complexes could lead to innovative cancer treatment strategies.

Electron 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...

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...

Cancer Therapies

Cancer therapies are various modes of treatment, such as surgery, radiation therapy, and chemotherapy that are administered to cancer patients.
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...

mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.
The mTOR pathway or the...

Drugs that Stabilize Microtubules

Microtubules are dynamic structures that undergo cycles of catastrophe and rescue. The microtubules play a central role in cell division by forming the spindle apparatus for segregating the chromosomes. This makes them ideal targets for regulating dividing cells in tumors and malignant cancer cells. Microtubule stabilizing drugs help stabilize the microtubule formation and promote its polymerization. Paclitaxel was the first microtubule stabilizing agent used as anticancer drug in chemotherapy...

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...
