Interaction Details
Imatinib is classified as belonging to the following category: Antineoplastics
American pawpaw (Asimina triloba) contains Annonacin, a natural compound that has been investigated for its potential anticancer effects. Laboratory studies suggest that Annonacin may inhibit or prevent the growth and spread of tumors or malignant cells by disrupting mitochondrial function, leading to cell death (source: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6672878/; https://www.nature.com/articles/s41419-018-0772-x). It is currently unknown how American pawpaw may interact, if at all, with prescription antineoplastic drugs. However, since both Annonacin and antineoplastic drugs can affect cell processes and metabolism, there is a theoretical risk of interactions that could affect treatment efficacy or increase the risk of side effects. Therefore, caution should be exercised when combining pawpaw with prescription antineoplastic drugs, and consulting with a healthcare professional is recommended before making changes to your medication regimen.

American Pawpaw Overview
Asimina triloba, also known as pawpaw, is a deciduous tree native to North America. It is recognized for its large, tropical-like leaves and distinctive oblong fruits resembling a mix of mangoes and bananas. Typically found in moist, fertile soils in forest understories or along riverbanks, the pawpaw tree is of medicinal interest due to its potential anticancer properties attributed to its acetogenin content, including annonacin. Annonacin has shown cytotoxic effects against cancer cells, particularly in laboratory studies, by disrupting mitochondrial function, leading to cell death. Other mechanisms are likely involved as well. While promising, more research is needed to fully understand its mechanisms and therapeutic potential. Other constituents of American pawpaw include epigallocatechin, epicatechin, and p-coumaric acid.
Imatinib Overview
-
Imatinib is used to treat certain types of leukemia (cancer that begins in the white blood cells) and other cancers and disorders of the blood cells. Imatinib is also used to treat certain types of gastrointestinal stromal tumors (GIST; a type of tumor that grows in the walls of the digestive passages and may spread to other parts of the body). Imatinib is also used to treat dermatofibrosarcoma protuberans (a tumor that forms under the top layer of skin) when the tumor cannot be removed surgically, has spread to other parts of the body, or has come back after surgery. Imatinib is in a class of medications called kinase inhibitors. It works by blocking the action of the abnormal protein that signals cancer cells to multiply. This helps stop the spread of cancer cells.
