The beta-diketone 1,1,1,2,2,3,3-heptafluoro-7,7-dimethyloctane-4,6-dione (FOD) translocates calcium from an aqueous medium into an organic phase. FOD is less efficient than but acts synergistically with A23187 in causing calcium translocation. The FOD-mediated process of calcium translocation is inhibited by NaCl, although the

We show that the relatively simple beta-diketone, 1.1.1.2.2.3.3-heptafluoro-7,7-dimethyloctane-4,6-dione, known as "fod", will solvate Ca2+ ions in an organic phase. In consequence it will transport Ca2+ across phospholipid bilayers. It acts as predicted for a Ca2+-transporting ionophore in two biological systems:

Since in the compound class of 2-ureidopyrimidines accessible through condensation of guanidinecarboxamide (1) with beta-diketones, representatives occur possessing hypnotic activity, the range of applicability of this synthesis on the one hand and the properties of the end products as related

This study presents supercritical carbon dioxide (scCO(2)) extraction as an inherently safer and cleaner sample treatment method for identifying trace gallium in urine samples. Extraction is performed in the presence of a fluorinated beta-diketones chelating agent, 2,2-dimethyl-6,6,7,7,8,8,8-heptafluoro-3,5-octanedione (HFOD), by unmodified

Journal of immunological methods, 63(2), 237-246 (1983-10-14)
A method for the production of human gamma interferon (HuIFN-gamma), which is both simple and efficient, has been developed. The 2 co-inducers, A-23187 and mezerein, stimulate human peripheral blood lymphocytes to produce high levels of HuIFN-gamma in both stationary cultures
