Tümokinoon

Tümokinoon on bioaktiivse toimega fütokemikaal, mida sisaldavad aed-mustköömne (Nigella sativa) seemned ja nendest valmistatud aed-mustköömne õlid ja aed-mustköömne ekstraktid.

 NSC 2228;Thymoquinon;THYMOQUINONE;thymolquinone;AURORA KA-6714;Thymoquinone,99%;p-Cymene-2,5-dione;TIMTEC-BB SBB008296;3,6-p-menthadiene-2,5-dione;P-MENTHA-3,6-DIENE-2,5-DIONE.

Farmakoloogilised uuringud 

Tümokinoon toimib antioksüdandina.

Tümokinoon (TQ) toimib immuunsüsteemi – modulleerides põletikumediaatoreid.

Loomkatsetes toimib tümokinoon vähivastase ainena – selle toime täpseid molekulaarseid mehhanisme ei tunta.

Aed-mustköömne õli ja tümokinoon on osade in vitro vähirakuliinide uuringutes efektiivsed vere-, kopsu-, neeru-, maksa-, kõhunäärme-, eesnäärme-, emakakaela, soole- ja nahavähi korral.

In vitro katsed (2008) inimese kõhunäärme vähirakkude liiniga näitasid, et tümokinooni lisamine tappis ligi 80 protsenti vähirakkudest. Tümokinoon kutsus esile nende rakkude programmeeritud raku surma kasutades geene p53, Bax, bcl-2 ja p21.
