In vitro	Rottlerin is extracted from the plasma and tissues using protein precipitation-extraction and analyzed by reverse-phase HPLC-DAD method. Significant levels of this compound are detected in cell lysates from rottlerin-treated HPAF-II cells. These data indicate that it is efficiently absorbed in cells in vitro.^[2]
In vivo	A xenograft model of pancreatic cancer is prepared by injection of 2×10⁶ HPAF-II cells subcutaneously into nude mice. A substantial amount of this compound is detected in tumor and plasma in mice fed this compound diet. These data indicate that this compound is efficiently absorbed in vivo and suggest a strong potential for this compound as a preventive or adjuvant supplement for pancreatic cancer.^[2]
