State Dependence of Mobilities for Kr⁺⁺in Kr at 88 K

Chemistry and biology of non-tetramic γ-hydroxy-γ-lactams and γ-alkylidene-γ-lactams from natural sources

“…The same is the case with the antitumor compound GKK1032A2 41 isolated from the Penicillium strain GKK1032. 37 Biosynthetic studies undertaken with this compound have suggested that it results from the ''head-totail'' cationic cascade of the polyene precursor 42, rather than from a Diels-Alder reaction. 38 Other compounds in the series that have been isolated include the antibiotic pyrrocidines A (43) and B (44) from the endophytic fungi Cyclindrocarpon sp.…”

Purification and characterization of nuclear alkaline phospholipase A2 in rat ascites hepatoma cells

“…Phospholipase A2 (PLA~) catalyzes the hydrolysis of the sn-2-ester bond of phospholipids and produces the precursors of potent lipid mediators, such as leukotrienes, prostaglandins and platelet activating factor. In mammalian cells, PLA2 has been found in various subcellular fractions, plasma membrane [1,2], Golgi membrane [3], microsome [4], mitochondria [5], lysosome [6], and cytosol [7,8]. To date, little information concerning nuclei is available, even inclusive of our previous report [9].…”

Variable-Temperature Ion Mobility Time-of-Flight Mass Spectrometry Studies of Electronic Isomers of Kr2+ and CH3OH+• Radical Cations

“…26,28,29 Also, Kr 2+ and Xe 2+ ions are reported, but only partially separated on the basis of mobility at 300 K, which does not afford baseline separation of the different electronic and spin states ( 3 P 0 , 3 P 1 , 3 P 2 , 1 D 2 , and 1 S 0 ). [30][31][32] A liquid nitrogen-cooled drifttube experiment was designed by Koizumi et al for highresolution separation and analysis of the doubly-charged symmetric electron transfer reaction of Kr 2+ and Xe 2+ . 31 They showed that, at temperatures of 88 K, the resolving power is sufficient to separate the different electronic states.…”
