Ganglioside GD3 diammonium is an acidic sphingolipid that exhibits promising biological activities. It can inhibit the proliferation of cancer cells, influence the opening of mitochondrial permeability transition pores (PTPC), induce cell apoptosis (apoptosis), and activate the caspase enzyme family. This compound is utilized in the research of cancer and neurodegenerative diseases.

Ganglioside GD3 diammonium exhibits higher expression in melanomas compared to melanocytes and is exclusively present during the early developmental stages of the fetal brain. Additionally, it is prominently expressed in activated T lymphocytes and T cell malignant tumor cells. The expression patterns of GD3 suggest its involvement in tumor phenotypes characterized by increased proliferation and frequent metastasis.
