Isogomisin O is a plant-derived compound that has been shown to inhibit the proliferation of cells in vitro. This compound is derived from schizandra, which is a type of fruit used in traditional Chinese medicine. Isogomisin O has been shown to be effective against skin cancer and inflammatory skin diseases, as well as for anti-aging purposes. It may also have anticancer properties due to its ability to inhibit the growth of tumor cells, as well as inhibiting blood pressure and lowering cholesterol levels. Isogomisin O’s mechanism of action is not yet known but it may involve inhibition of protein synthesis or deoxyschizandrin, a component that has been shown to inhibit the activity of the enzyme catalysed.
