[Screening of substances and extracts of plant origin in Walker carcinosarcoma 256]
Anais Da Academia Brasileira De Ciencias
|January 1, 1975
Abstract:
The authors realized a series of tests with extracts or plants or substances of plant origin in the experimental tumor Walker 256 to determine whether the extracts show anticancer activity. The samples tested were obtained in the authors laboratory or came from other centers. Thirty extracts, 26 of which were inactive and 4 active, were tested. The results shown in the tables are primary screens.
Insights
Researchers screened plant extracts for anticancer activity against the Walker 256 tumor model. Four out of thirty extracts demonstrated significant anticancer effects, warranting further investigation.
Area of Science:
- Pharmacology
- Oncology
- Natural Products Chemistry
Background:
- Plant-derived compounds have historically been a rich source of anticancer agents.
- The need for novel chemotherapeutic agents remains high due to cancer prevalence and resistance.
- Investigating natural products offers a promising avenue for discovering new anticancer drugs.
Purpose of the Study:
- To evaluate the in vivo anticancer potential of various plant extracts.
- To identify specific plant-derived substances exhibiting activity against the Walker 256 experimental tumor model.
- To conduct preliminary screening of natural product extracts for cytotoxic effects.
Main Methods:
- Preparation and acquisition of plant extracts from internal and external sources.
- Administration of thirty distinct plant extracts to subjects with experimental Walker 256 tumors.
- In vivo screening assay to assess tumor growth inhibition or regression.
Main Results:
- Out of thirty tested extracts, twenty-six showed no significant anticancer activity.
- Four plant extracts exhibited notable anticancer activity in the Walker 256 tumor model.
- These results represent primary screening data, indicating potential leads for further research.
Conclusions:
- Certain plant extracts possess demonstrable anticancer activity against the Walker 256 tumor.
- The identified active extracts serve as promising candidates for further preclinical development.
- This study highlights the potential of natural products in cancer therapy research.
