The Patent Office of the Republic of Poland granted two patents to the University of Gdańsk for inventions applicable in cancer treatment. The subject of the inventions are new active ingredients based on anthraquinone derivatives, their extraction techniques and molecular systems structurally constructed from an anthracene rings. The inventors are prof. dr hab. inż. Tadeusz Piotr Ossowski and dr Paweł Niedziałkowski from the Department of Analytical Chemistry at the Faculty of Chemistry of the University of Gdańsk.

Two new patents were granted to the UG Faculty of Chemistry for the following inventions: PL235255 “New Analogs of  9,10-anthraquinone containing piperazines substituted with various functional groups and their extraction techniques” and PL235483 “Multiparticle molecular systems containing 9,10-anthraquinone rings”.

The subject of inventions are new active ingredients based on anthraquinone derivatives, their extraction techniques and molecular systems structurally constructed from an anthracene rings. The new compounds, obtained by novel extraction methods, have cytostatic properties, they inhibit the growth of cancer cells. Another characteristics of the new compounds is their reduced cardiotoxicity, which allows using smaller therapeutic doses with simultaneously increased cytotoxicity towards cancer cells and slower build-up of resistance. New extraction methods of anthraquinone derivatives allow for their quicker and more efficient manufacturing.

Both inventions could be applied in cancer treatment.
