Insights

Carpesium rosulatum plant extracts show cytotoxic activity against human cancer cells. The isolated compound CT-2 demonstrated potent antiproliferative effects, particularly against the SK-MEL-2 cell line.

Area of Science:

  • Phytochemistry
  • Pharmacology
  • Natural Products Chemistry

Background:

  • Natural products are a rich source of potential anticancer agents.
  • Carpesium rosulatum (Compositae) is a plant species with potential medicinal properties.

Purpose of the Study:

  • To investigate the antiproliferative activity of Carpesium rosulatum extracts against human cancer cell lines.
  • To isolate and identify active compounds responsible for the observed cytotoxicity.

Main Methods:

  • Extraction of the whole plant using chloroform.
  • Chromatographic isolation of compounds.
  • Cytotoxicity assays against A549, SK-OV-3, SK-MEL-2, XF498, and HCT15 cancer cell lines.
  • Chemical characterization of isolated compounds (CT-1 and CT-2).

Main Results:

  • Chloroform extracts of Carpesium rosulatum exhibited significant cytotoxic activity.
  • Two sesquiterpene lactones, CT-1 and CT-2, were isolated.
  • CT-2 displayed the most potent cytotoxicity with an IC50 value of 7.88 microM against SK-MEL-2 cells.

Conclusions:

  • Carpesium rosulatum is a source of cytotoxic sesquiterpene lactones.
  • CT-2 is a promising lead compound for developing new anticancer therapies.
  • Further research into CT-2's mechanism of action is warranted.

Inhibition of Cdk Activity02:34

Inhibition of Cdk Activity

The orderly progression of the cell cycle depends on the activation of Cdk protein by binding to its cyclin partner. However, the cell cycle must be restricted when undergoing abnormal changes. Most cancers correlate to the deregulated cell cycle, and since Cdks are a central component of the cell cycle, Cdk inhibitors are extensively studied to develop anticancer agents. For instance, cyclin D associates with several Cdks, such as Cdk 4/6, to form an active complex. The cyclin D-Cdk4/6 complex...

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...
Drugs that Stabilize Microtubules01:15

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...
Cancer02:18

Cancer

Cancers arise due to mutations in genes involved in the regulation of cell division, which leads to unrestricted cell proliferation. Modern science and medicine have made great strides in the understanding and treatment of cancer, including eradicating cancer in some patients. However, there is still no cure for cancer. This is largely due to the fact that cancer is a large group of many diseases.
