Microlunatus parietis sp. nov., isolated from an indoor wall [PDF]
, 2009 A Gram-positive, coccoid, non-endospore-forming actinobacterium (strain 12-Be-011T) was isolated from indoor wall material. Based on 16S rRNA gene sequence comparisons, strain 12-Be-011T was clearly shown to belong to the genus Microlunatus and was most ...

Chemistry – A European Journal, EarlyView.The convergent synthesis of Lewis‐X‐containing betulinic acid and echinocystic acid saponins (1 and 2) is presented. The synthetic saponins were shown to inhibit, at the low micromolar range, the DC‐SIGN‐ and L‐SIGN‐mediated transfer of HIV‐1 infection to CD4‐positive cells, whereas free Lewis‐X, aglycones, and structurally similar triterpenoid ...

Synthesis of Rhamnose‐Modified Lewis‐X‐Containing Saponins
European Journal of Organic Chemistry, EarlyView.The synthesis of triterpenoid saponins bearing a Lewis‐X trisaccharide analogue, in which the fucose residue is replaced by a rhamnose, is presented. These saponins, designed as negative controls in dendritic cell‐specific intercellular adhesion molecule‐3‐grabbing nonintegrin‐targeted therapeutic applications, are prepared through iterative and ...

A simple and rapid method for measuring α-D-phosphohexomutases activity by using anion-exchange chromatography coupled with an electrochemical detector [PDF]
PeerJ, 2016 The interconversion of hexose-6-phosphate and hexose-1-phosphate can be directly analyzed by high-performance anion-exchange chromatography coupled with an electrochemical detector (HPAEC-PAD). Thus, this method can be used to measure the activities of N-

Brevibacterium sandarakinum sp. nov., isolated from a wall of an indoor environment [PDF]
, 2009 A Gram-stain-positive, rod-shaped, non-endospore-forming, orange-pigmented (coloured) actinobacterium (01-Je-003T) was isolated from the wall of an indoor environment primarily colonized with moulds.

Protein kinase A controls the hexosamine pathway by tuning the feedback inhibition of GFAT-1
Nature Communications, 2021 The glutamine fructose-6-phosphate amidotransferase 1 (GFAT-1) is the rate-limiting enzyme in the hexosamine pathway producing uridine 5’-diphospho-N-acetyl-D-glucosamine (UDP-GlcNAc), an essential glycosylation precursor.

Synthesis Of Benzyl Beta D-Gulopyranosiduronic Acid-(2\u27,3\u27: 4,5)-Oxazolidone-2 [PDF]
, 1966 Although D-glucosamine has been found as a constituent of some antibiotics (28), very little research has been carried out in the area of synthetic preparations.
