The relaxivity of Gd(HP-DO3A) was studied as a function of pH and buffer composition in order to identify the main factors of the observed relaxation enhancement due to the exchange of the coordinated hydroxyl proton. It was established that the para

Direct Observation of Carbohydrate Hydroxyl Protons in Hydrogen Bonds with a Protein

Autor: Taigh Anderson, Gustav Nestor, Stefan Oscarson, Angela M. Gronenborn

Publikováno v: Journal of the American Chemical Society. 140:339-345

Hydroxyl proton resonances of uniformly 13C-labeled Manα(1-2)Manα(1-2)ManαOMe (Man3) bound to cyanovirin-N (CV-N) were detected at ambient temperature in aqueous solution by NMR spectroscopy. The directions of the hydroxyl groups were determined o

Unequivocal 13 C NMR assignment of cyclohexadienyl rings in bromotyrosine-derived metabolites from marine sponges

Autor: Rohan A. Davis, John A. Kalaitzis, Ronald J. Quinn

Publikováno v: Magnetic Resonance in Chemistry. 50:749-754

Bromotyrosine-derived compounds are commonly isolated from Verongida sponges and are a major class of marine natural products. Here we report on the unequivocal 13C NMR assignment of the brominated carbons at positions C-2 and C-4 of the cyclohexadie

Methylated Polysulfotetraphenylcalix[4]resorcinolarene

Autor: N. V. Malyshenko, L. P. Abramova, G. N. Al'tshuler, S. Yu. Lyrshchikov

Publikováno v: Russian Journal of Applied Chemistry. 85:1255-1258

A new polymer was prepared by etherifi cation of phenolic OH groups in polysulfotetraphenylcalix[4]resorcinolarene. It exhibits high ion-exchange capacity and is less hydrophilic than the starting polymer.

Investigation into the conformation of a series of 2-alkyl-1-(o-alkylphenyl)cyclohexanols. Part 3: Synthesis and conformation of some trans-1-(o-alkylphenyl)decahydro-1-naphthols

Autor: Hendrik Timmerman, W. Th. Nauta

Publikováno v: Recueil des Travaux Chimiques des Pays-Bas. 87:1277-1280

Several trans-1-(o-alkylphenyl)decahydro-1-naphthols were synthesised from trans-octahydro-1(2H)-naphthalenone with aryl-lithium. Their conformations were assigned on the ground of the chemical shift of the hydroxyl proton. A comparison was made with

Investigation into the conformation of a series of 2-alkyl-1-(o-alkylphenyl)cyclohexanols. Part 2: Synthesis and NMR spectra of some o-alkylbenzyl alcohols

Autor: W. Th. Nauta, Hendrik Timmerman, J. Zaagsma

Publikováno v: Recueil des Travaux Chimiques des Pays-Bas. 87:1272-1276

A series of o-alkylbenzyl alcohols was synthesised; the NMR spectra were compared with those of correspondingly substituted o-alkylphenyl cyclohexanols in order to ascertain how the o-alkyl substituents in the cyclohexanols investigated affect the sh
