Extracts from Camptotheca (the "happy tree" or "cancer tree") were used to develop the chemotherapeutic drug Topotecan. Plant sources of anti-cancer agents are plants, the derivatives of which have been shown to be usable for the treatment or prevention of cancer in humans. [1] [2]
It is the only known source of artemisinin, a drug that has been used to treat fevers due to malaria, exhaustion, or many other causes, since ancient times. [14] Upon further study, scientists have found that Sweet Wormwood inhibits activity of various bacteria, viruses, and parasites and exhibits anti-cancer and anti-inflammatory properties.
In the fields of medicine, biotechnology, and pharmacology, drug discovery is the process by which new candidate medications are discovered. [1]Historically, drugs were discovered by identifying the active ingredient from traditional remedies or by serendipitous discovery, as with penicillin.
Natural products sometimes have pharmacological activity that can be of therapeutic benefit in treating diseases. [96] [97] [98] Moreover, synthetic analogs of natural products with improved potency and safety can be prepared, and therefore, natural products are often used as starting points for drug discovery. Natural product constituents have ...
Pharmacognosy is the study of crude drugs obtained from medicinal plants, animals, fungi, and other natural sources. [1] The American Society of Pharmacognosy defines pharmacognosy as "the study of the physical, chemical, biochemical , and biological properties of drugs, drug substances, or potential drugs or drug substances of natural origin ...
Chaparral (or Larrea tridentata) – a plant used to make a herbal remedy which is sold as cancer treatment. Cancer Research UK state that: "We don't recommend that you take chaparral to treat or prevent any type of cancer." [67] Chlorella – a type of algae promoted for its health-giving properties, including a claimed ability to treat cancer ...
Because of the difference in FAS expression between normal cells and cancer cells, orlistat selectively targets tumor cells. Due to this FAS is a potential drug target in cancer therapy. [34] [37] Orlistat works locally in the intestines as a lipase inhibitor, and therefore suffers from several limitations in its development as a systemic drug.
Polymer-drug conjugates are drug molecules held in polymer molecules, which act as the delivery system for the drug. Polymer drugs have passed multidrug resistance (MDR) testing and hence may become a viable treatment for endocrine-related cancers. A cocktail of pendant drugs could be delivered by water-soluble polymer platforms.
