(R,R)-Disynephrine ether bis(hydrogen sulfate)
THE ASYMMETRIC UNIT OF THE TITLE COMPOUND [SYSTEMATIC NAME: (R,R)-2,4-bis-(4-hydroxy-phen-yl)-N,N'-dimethyl-3-oxapentane-1,5-diammonium bis-(hydrogen sulfate)], C(18)H(26)N(2)O(3) (2+)·2HSO(4) (-), contains one half-cation and one hydrogen sulfate anion. The cation has crystallographically imposed twofold symmetry with the rotation axis passing through the central ether O atom. Hydrogen bonds b...
متن کاملSynthesis of sulfate esters of phosphatidylglycerol (diphytanyl ether analog).
Synthesis of 1-sn-phosphatidyl-3'-sn-glycero-1'-sulfate (phosphatidylglycero-1-sulfate) was achieved by monosulfation of 1-sn-phosphatidyl-3'-sn-glycerol (diphytanyl ether analog) with an equimolar amount of SO(3)-pyridine complex at room temperature; with excess sulfation reagent at 60 degrees C, the 1',2'-disulfate ester was obtained. The phosphatidyl-glycero-2-sulfate isomer was synthesized ...
متن کاملInteractions between selected bile salts and Triton X-100 or sodium lauryl ether sulfate
BACKGROUND In order to develop colloidal drug carriers with desired properties, it is important to determine physico-chemical characteristics of these systems. Bile salt mixed micelles are extensively studied as novel drug delivery systems. The objective of the present investigation is to develop and characterize mixed micelles of nonionic (Triton X-100) or anionic (sodium lauryl ether sulfate)...
متن کاملIn vitro metabolism of testosterone sulfate and testosterone tetrahydropyranyl ether in male rat liver.
In vitro metabolism of 3H-testosterone 17-sulfate(3H-TS)and 14C-testosterone 17-tetrahydropyranyl ether(14C-TP)was studied by incubation with 20000•~g or 105000•~g supernatant and microsomal fractions of male rat liver homogenate under carbon monoxide atmosphere or in air.The results demonstrated that the steroidal ring A of 3H-TS was readily metabolized by microsomal ƒ¢4-5ƒ¿-hydrogenase,while ...
متن کاملTemperature-Dependent Alkyl Glycerol Ether Lipid Composition of Mesophilic and Thermophilic Sulfate-Reducing Bacteria
The occurrence of non-isoprenoid alkyl glycerol ether lipids in Bacteria and natural environments is increasingly being reported and the specificity and diagenetic stability of these lipids make them powerful biomarkers for biogeochemical and environmental studies. Yet the environmental controls on the biosynthesis of these peculiar membrane lipids remain poorly documented. Here, the lipid cont...
