Types of anticancer agents isolated from plants

Area of Science:

• Pharmacology
• Natural Products Chemistry
• Oncology

Background:

• The National Cancer Institute's chemotherapy program has historically investigated plant-derived compounds.
• Identifying novel anticancer agents from natural sources is crucial for drug discovery.

Purpose of the Study:

• To list and classify active compounds isolated from plants tested in the National Cancer Institute's chemotherapy program.
• To discuss the antitumor activity of these compounds in experimental tumor systems.
• To explore structure-activity relationships for potential clinical development.

Main Methods:

• Systematic listing and classification of plant-derived compounds.
• Evaluation of compound activity in established and novel experimental tumor models, including B16 melanoma and Lewis lung carcinoma.
• Analysis of structure-antitumor activity relationships.

Main Results:

• A comprehensive list of plant-derived compounds tested is presented.
• Specific compound classes demonstrate significant activity in various experimental tumor systems.
• Structure-activity relationship analyses identify promising candidates for further investigation.

Conclusions:

• Certain plant-derived compounds warrant further investigation for their potential as anticancer drugs.
• The study provides a foundation for prioritizing compounds for preclinical and clinical trials.
• Continued exploration of natural products remains vital for advancing cancer chemotherapy.
