Stereochemical effects during [M-H]- dissociations of epimeric 11-OH-17beta-estradiols and distant electronic effects of substituents at C(11) position on gas phase acidity. JOURNAL OF THE AMERICAN SOCIETY FOR MASS SPECTROMETRY 2009; 20:2318-2333. [PMID: 19818644 DOI: 10.1016/j.jasms.2009.08.017] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/19/2009] [Revised: 08/21/2009] [Accepted: 08/21/2009] [Indexed: 05/28/2023]
Abstract
The affinity of estradiol derivatives for the estrogen receptor (ER) depends strongly on nature and stereochemistry of substituents in C(11) position of the 17beta-estradiol (I). In this work, the stereochemistry effects of the 11alpha-OH-17beta-estradiol (III(alpha)) and 11beta-OH-17beta-estradiol (III(beta)) were investigated using CID experiments and gas-phase acidity (DeltaH degrees (acid)) determination. The CID experiments showed that the steroids decompose via different pathways involving competitive dissociations with rate constants depending upon the alpha/beta C(11) stereochemistry. It was shown that the fragmentations of both deprotonated [III(alpha)-H]- and [III(beta)-H]- epimers were initiated by the deprotonation of the most acidic site, i.e. the phenolic hydroxyl at C(3). This view was confirmed by H/D exchange and double resonance experiments. Furthermore, the DeltaH degrees (acid) of both epimers (III(alpha) and III(beta)), 17beta-estradiol (I), and 17-desoxyestradiol (II) was determined using the extended Cooks' kinetic method. The resulting values allowed us to classify steroids as a function of their gas-phase acidity as follows: (III(beta)) >> (II) > (I) > (III(alpha)). Interestingly, the alpha/beta C(11) stereochemistry appeared to influence strongly the gas-phase acidity. This phenomenon could be explained through stereospecific proton interaction with pi-orbital cloud of A ring, which was confirmed by theoretical calculation.

Abstract
Two Rhodococcus erythropolis strains, HL 24-1 and HL 24-2, were isolated from soil and river water by their abilities to utilize 2,4-dinitrophenol (0.5 mM) as the sole source of nitrogen. Although succinate was supplied as a carbon and energy source during selection, both isolates could utilize 2,4-dinitrophenol also as the sole source of carbon. Both strains metabolized 2,4-dinitrophenol under concomitant liberation of stoichiometric amounts of nitrite and 4,6-dinitrohexanoate as a minor dead-end metabolite.

Abstract
The chemical structure of the K14-antigenic polysaccharide (K14 antigen) of Escherichia coli 06:K14:H31 was elucidated by determination of the composition, 1H- and 13C-n.m.r. spectroscopy, periodate oxidation, and study of the oligosaccharides obtained by partial hydrolysis. The polysaccharide consists of [O-(2-acetamido-2-deoxy-beta-D-galactopyranosyl)-(1 leads to 5)-O-(3-deoxy-beta-D-manno-octulopyranosylonic acid)-(2 leads to 6)] repeating units, approximately 60% of the octonic acid units being O-acetylated and approximately 10% O-propionylated at O-8. The sequence of acetylated and propionylated residues is not known. The serologically-specific part of the K14 antigen residues in the polysaccharide part.
