An acidic polysaccharide was obtained from Psychrobacter maritimus 3pS isolated from a Siberian cryopeg sample (Kolyma lowland). The following structure of the tetrasaccharide repeating unit of the polysaccharide was established by sugar analysis along with (1)H and (13)C NMR spectroscopy: →2)-α-L-Rhap-(1→4)-α-D-GalpNAcA-(1→3)-α-D-QuipNAc4NHb-(1→3)-β-D-QuipNAc4NHb-(1→ where D-GalNAcA indicates ...

Phenylboronic acid esters are formed by the three common 2-deoxy aldoses: 2-deoxy-d-erythro-pentose ('2-deoxy-d-ribose'), 2-deoxy-d-lyxo-hexose ('2-deoxy-d-galactose'), and 2-deoxy-d-arabino-hexose ('2-deoxy-d-glucose'). The major species that was formed from equimolar quantities of boronic acid and the aldose, was the 3,4-monoester of the pentopyranose in a skew-boat conformation, and the 4,6-...

The title compound is a co-crystal of the cis and trans isomers, namely cis-bis-[1,1,1,5,5,5-hexa-fluoro-pentane-2,4-dionato(1-)-κ(2)O,O']bis-(4-phenyl-pyridine N-oxide-κO)copper(II)-trans-bis-[1,1,1,5,5,5-hexa-fluoro-pentane-2,4-dionato(1-)-κ(2)O,O']bis(4-phenyl-pyridine N-oxide-κO)copper(II) (2/1), [Cu(C(5)HF(6)O(2))(2)(C(11)H(9)NO)(2)]. In both isomers, the coordination geometry of the Cu(2+...

The 2-deoxy-D-glucose method was used to study asymmetries in cerebral metabolic activity in neonatal rats. Left-right asymmetries in 2-deoxy-D-glucose uptake were observed in hippocampus, diencephalon, cortex, and medulla-pons: 2-deoxy-D-glucose incorporation was greater in right hippocampus, right diencephalon, left cortex, and left medulla-pons. These asymmetries occurred only in females. We...

Synopsis The present werlc has been undertaken to assess the effects of a small dose of 2-deoxy-D-glucose on proliferation of fibrob]asts in culture by morphological criteria. Fibroblasts in culture medium with 2-deoxy-D-glucose proliferated only to a slight clegree, but eell confluence was not achieved, They became swollen and the cytoplasm was increasingly occupied by lucent area. These chang...
