Summary
Researchers investigated the cytostatic activity of plant extracts. Hamelia patens and Lippia alba showed the most promising results in inhibiting cell growth.
Area of Science:
- Phytochemistry and Pharmacology
- Exploration of natural products for biological activity.
Background:
- Superior plants are a rich source of bioactive compounds.
- Cytostatic agents are crucial in cancer research and treatment.
Purpose of the Study:
- To evaluate the cytostatic activity of various plant extracts.
- To identify plant species with significant inhibitory effects on cell proliferation.
Main Methods:
- Microbiologic assay described by Kubas (1972).
- Testing of aqueous, alcoholic, and ketonic extracts.
- Screening of 18 parts from 9 plant species across multiple families.
Main Results:
- Hamelia patens demonstrated significant cytostatic activity.
- Lippia alba, Lepidium virginicum, Cassia ligustrina, Bursera simaruba, and Heliotropium campechianum also exhibited notable activity.
Conclusions:
- Several plant extracts possess promising cytostatic properties.
- Hamelia patens is a potential source for developing new cytostatic agents.

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...
Cell Culture
Most vertebrate cells grow in vitro attached to a substrate as a monolayer, called adherent cultures. The flasks and plates used to grow cells are chemically treated to facilitate cell attachment. However, a few cell types, such as hematopoietic cells, can grow in a suspension. In contrast to adherent cultures, suspension cultures can grow in non-treated cultureware using magnetic stirrers or spinner flasks to agitate the culture media
