Salvinia Cyctotoxic Compounds for Treatment of Cancer

Tech ID:

Novel plant-derived compounds that have cytotoxic properties against cancer cells and therefore may be potent anticancer therapeutics have been discovered by UT Health San Antonio researchers. These compounds are derived from giant salvinia, one of the most noxious invasive species of plants in the world. The compounds showed selective cytotoxic activity against several human cancer cell lines, including forms of lung cancer, prostate cancer, pancreatic cancer, breast cancer, and leukemia.



Giant salvinia ( Salvinia molesta ) is one of the most widespread and environmentally, economically and socially destructive invasive plant species in the world. The salvinia also provides habitat for snails that are intermediate hosts for Schistosoma sp. which causes the parasitic disease Schistosomiasis, the second most socioeconomically devastating parasitic disease after malaria. However, the plant may prove beneficial for its novel compounds and would provide an additional financial incentive to control this plant by harvesting it for pharmaceutical use.


Commercial Applications & Advantages:

The novel plant compounds have wide-reaching applicability in the field of oncology and provide the following benefits:

  • Several plant-derived molecules have been effective and are highly valued by pharmaceutical companies, including Taxol and Abraxane
  • Plant-derived compounds represent a $4.4 Billion market (33% of the market share)
  • Plant-derived compounds and their analogs offer novel therapeutic alternatives
  • Source of compounds are from a globally-abundant species, and extraction of the compounds would be economically viable globally
