Abstract

Insights

Marine bromophenols from algae inhibit tumor cell growth by inducing aneuploidy and cell cycle arrest, not apoptosis. These compounds show potential as anticancer agents.

Area of Science:

  • Marine natural products
  • Pharmacology
  • Cancer biology

Context:

  • Marine algae like Rhodomela confervoides are a source of bioactive compounds.
  • Understanding the cytotoxic mechanisms of marine-derived compounds is crucial for drug discovery.

Purpose:

  • To evaluate the in vitro antitumor effects of two bromophenols from Rhodomela confervoides.
  • To elucidate the mechanism of action against Hela, MGC, and BGC-823 tumor cells.

Summary:

  • Two bromophenols exhibited cytotoxic activity against Hela, MGC, and BGC-823 cells.
  • Bromophenols induced aneuploidy and cell cycle inhibition (G1 phase block), but not apoptosis.
  • Hela cells demonstrated the highest sensitivity to the tested bromophenols.

Impact:

  • Identifies marine bromophenols as potential anticancer agents.
  • Elucidates novel mechanisms of tumor cell growth inhibition involving aneuploidy and cell cycle arrest.
  • Provides a basis for further investigation of these compounds in cancer therapy.

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...

Drugs that Destabilize Microtubules

Microtubules are dynamic structures and can be regulated by microtubule targeting agents (MTAs). Microtubule destabilizing drugs are a class of MTAs that destabilize and prevent microtubules' polymerization. Both natural and synthetic chemicals can be found under this class of drugs. Vincristine and vinblastine, two vinca alkaloids, and colchicine were among the first to be discovered. These drugs can affect cells in various ways, either by inducing a change in cell morphology, preventing...
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...
Antifungal Agents01:15

Antifungal Agents

Amphotericin B is a broad-spectrum antifungal agent that exploits structural differences between fungal and mammalian cell membranes. Its amphipathic structure—featuring a hydrophobic polyene-lactone ring and a hydrophilic region containing mycosamine and carboxylic acid groups—enables selective binding to ergosterol, a sterol predominantly found in fungal plasma membranes. This selective interaction underlies the drug’s antifungal activity, although weak binding to cholesterol contributes to...
