Mutagenicity and Carcinogenicity01:25

Mutagenicity and Carcinogenicity

2.2K
Mutagenicity and carcinogenicity refer to the ability of drugs to cause genetic defects and induce cancer, respectively. The International Agency for Research on Cancer (IARC) classifies agents into four groups based on their carcinogenic potential. Group 1 agents are known human carcinogens; group 2A agents are probably carcinogenic to humans; group 3 agents lack data to support their role in carcinogenesis; and group 4 includes agents for which data support that they are not likely to be...

Electron Transport Chain: Complex I and II01:46

Electron Transport Chain: Complex I and II

19.6K
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...

Cancer-Critical Genes I: Proto-oncogenes

12.0K
Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
Such genes that act...

Targeted Cancer Therapies02:57

Targeted Cancer Therapies

9.1K
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...

Area of Science:

  • Natural Products Chemistry
  • Pharmacology
  • Oncology

Background:

  • Acetogenins (ACGs) are a chemically under-investigated family of natural compounds.
  • A comprehensive review of 133 ACGs with documented anti-tumor activity is presented.

Purpose of the Study:

  • To compile and analyze the chemical structures and anticancer biological activities (in vitro and in vivo) of acetogenins.
  • To identify potent acetogenins for potential lead development in cancer therapy.

Main Methods:

  • Literature review and compilation of data on 133 acetogenins.
  • Analysis of chemical structures and in vitro/in vivo anticancer activity (ED50 values).
  • Evaluation of acetogenins against multi-drug resistant cancer cell lines.

Main Results:

  • Potency ranking: adjacent bis-THF ACGs > nonadjacent bis-THF ACGs > mono-THF ACGs > linear-THF ACGs.
  • Highly potent adjacent bis-THF ACGs include asiminocin, asiminecin, asiminacin, and asimin (ED50: 10^-9 to 10^-12 μg/mL).
  • Several ACGs demonstrated significant in vivo activity and suppressed proliferation of multi-drug resistant cells.

Conclusions:

  • Acetogenins represent a promising source of lead compounds for cancer prevention and treatment.
  • Further extensive in vivo studies are necessary for lead development.
  • Certain acetogenins show efficacy against resistant tumor cells, addressing a critical need in oncology.
