A tetrahydroisoquinoline-monoterpene glucoside and an iridoid glucoside from Alangium kurzii.
From the leaves of Alangium kurzii, a new tetrahydroisoquinoline-monoterpene glucoside, 6-O-methyl-N-deacetylipecosidic acid and a new iridoid glucoside, 10-O-benzoyladoxosidic acid, were isolated along with alangiside, demethylalangiside, 6''-O-beta-D-glucosylhenryoside, uridine and four known flavonoid glycosides. The structures of new glucosides were determined on the basis of spectroscopic ...
متن کاملRotational vertebral artery occlusion at C1-C2.
Compromise of blood flow in the vertebral arteries associated with head rotation is generally considered an uncommon cause of vertebrobasilar insufficiency. It can occur at virtually any level of the cervical spine. We present two cases of transient total occlusion of the left vertebral artery at the atlantoaxial joint during head rotation to the right. In one case, the contralateral vertebral ...
متن کاملχ_{c1} and χ_{c2} Resonance Parameters with the Decays χ_{c1,c2}→J/ψμ^{+}μ^{-}.
The decays χ_{c1}→J/ψμ^{+}μ^{-} and χ_{c2}→J/ψμ^{+}μ^{-} are observed and used to study the resonance parameters of the χ_{c1} and χ_{c2} mesons. The masses of these states are measured to be m(χ_{c1})=3510.71±0.04(stat)±0.09(syst) MeV and m(χ_{c2})=3556.10±0.06(stat)±0.11(syst) MeV, where the knowledge of the momentum scale for charged particles dominates the systematic uncertainty. The mome...
متن کاملIdentification of hnRNP C1/C2 as an Autoantigen in Patients with Behcet’s Disease
Background: Ribonucleoproteins particles that form the spliceosomes are among the most frequently targeted molecules of the autoimmune response. In the last few years, autoantibodies against all A/B hnRNP proteins have been found in the sera of patients with rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), mixed connective tissue disease (MCTD), and serve as diagnostic markers for...
متن کاملSynthesis of Phthalocyanines with a Pentafluorosulfanyl Substituent at Peripheral Positions
The pentafluorosulfanyl (SF5) group is more electronegative, lipophilic and sterically bulky relative to the well-explored trifluoromethyl (CF3) group. As such, the SF5 group could offer access to pharmaceuticals, agrochemicals and optoelectronic materials with novel properties. Here, the first synthesis of phthalocyanines (Pcs), a class of compounds used as dyes and with potential as photodyna...
