31, 95% CI = 3.09, 3.55). Among AUD patients, mortality risk was elevated in the low SES category (HR = 1.23, 95% CI = 1.04, 1.45). Relative mortality risk from AUD was significantly higher in the high SES (HR = 8.65, 95% CI = 6.16, 12.14) compared with the low SES categories (HR = 3.29, 95% CI = 2.61, 4.15). CONCLUSION Admission to treatment for alcohol use disorders in Norway appears to decrease with increasing socio-economic status, and relative mortality risk from alcohol use disorder appears to increase with increasing socio-economic status. © 2020 Society for the Study of Addiction.A direct and highly enantioselective reaction of N -azidoacetyl-1,3-thiazolidine-2-thione with trimethyl orthoformate catalyzed by Tol-BINAPNiCl 2 in the presence of TESOTf and 2,6-lutidine is reported. The heterocyclic scaffold can be easily removed by addition of a wide array of amines to give the corresponding enantiomerically pure 2-azido-3,3-dimethoxypropanamides in high yields. Appropriate manipulation of the N -benzyl amide derivative provides a quick and efficient access to the antiepileptic agent lacosamide through a new enantioselective C-C bond-forming process. DFT-Computational studies uncover clues for the understanding of the remarkable stereocontrol of the addition of a nickel(II) enolate to a putative oxocarbenium intermediate from trimethyl orthoformate. © 2020 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.The nitridophosphates AE P 8 N 14 ( AE = Ca, Sr, Ba) were synthesized at 4-5 GPa and 1050-1150 °C applying a 1000 t press with multianvil apparatus, following the azide route. The crystal structures of CaP 8 N 14 and SrP 8 N 14 are isotypic. The space group Cmcm was confirmed by powder X-ray diffraction. The structure of BaP 8 N 14 (space group Amm 2) was elucidated by a combination of transmission electron microscopy and diffraction of microfocused synchrotron radiation. Phase purity was confirmed by Rietveld refinement. CDK inhibitor IR spectra are consistent with the structure models and the chemical compositions were confirmed by X-ray spectroscopy. Luminescence properties of Eu 2+ doped samples were investigated upon excitation with UV to blue light. CaP 8 N 14 ( λ em = 470 nm; fwhm = 1380 cm -1 ) and SrP 8 N 14 ( λ em = 440 nm; fwhm = 1350 cm -1 ) can be classified as the first ultra-narrow-band blue-emitting Eu 2+ doped nitridophosphates. BaP 8 N 14 shows a notable broader blue emission ( λ em = 417/457 nm; fwhm = 2075/3550 cm -1 ). © 2020 WILEY-VCH Verlag GmbH & Co.

To gain quantitative information on fluorination at the 6-position of steroids, we conducted kinetics studies on enol ester derivatives of progesterone, testosterone, cholestenone and hydrocortisone with a series of electrophilic N-F reagents. We explored the stereoselectivities of fluorination reactions of progesterone enol acetate and the kinetic effects of additives, including methanol and water. The kinetics of epimerisation of 6β-fluoroprogesterone to the more pharmacologically active 6α-fluoroprogesterone isomer in HCl/acetic acid solutions are detailed. © 2020 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.Bifunctional unsaturated reagents designed to undergo palladium-catalyzed cross-coupling reactions with complementary polyenyl connective fragments are highly useful for the undoubtedly challenging synthesis of polyenes. The current toolkit of building blocks for the bidirectional formation of Csp 2 -Csp 2 single bonds of polyenes includes homo-bisfunctionalized reagents with equal or unequal reactivity (due to steric and/or electronic factors), and heterobisfunctionalized counterparts containing either two different nucleophiles, two electrophiles or one of these functionalities and a latent nucleophile that can be unmasked when desired. The combination of these bifunctional linchpin reagents using tactics that modulate the reactivity of each terminus in order to achieve the required connection have streamlined the synthesis of polyenes of great complexity using (iterative) cross-coupling methods for Csp 2 -Csp 2 bond formation. Reaction conditions for the Pd-catalyzed cross-coupling reactions are mild and functional group-tolerant, and therefore these protocols allow to construct the polyene structures using shorter unsaturated reactants with the desired geometries, since in general the products preserve the stereochemical information of the connected cross-coupling partners. © 2020 WILEY-VCH Verlag GmbH & Co.

METHODS CYP2C19 extensive metabolizers (EMs), intermediate metabolizers (IMs), and poor metabolizers (PMs) (18 subjects/group) participated in a randomized, open-label, two-period cross-over study. Each study period lasted 7 days, with a loading dose of 24 mg of vicagrel or 300 mg of clopidogrel on day 1, and maintenance doses of 6 mg of vicagrel or 75 mg of clopidogrel daily from day 2 to day 7. The pharmacokinetics and pharmacodynamics were assessed on day 1 and day 7. RESULTS After a loading dose, the AUC0-t of the active metabolite H4 by vicagrel was slightly lower in IMs and PMs (decreased by 21% and 27%, respectively) compared to EMs. Similar results were found after maintenance doses. In EMs, the AUC0-t of H4 by vicagrel was somewhat higher than clopidogrel after the loading dose, and comparable with clopidogrel (90% CI 0.94, 1.21) after the maintenance doses. However, it was much higher than clopidogrel in PMs, with a 1.28-fold (loading dose) and a 73% (maintenance doses) increases compared to clopidogrel (P less then 0.001). Consequently, the IPA by vicagrel was greater than clopidogrel after both loading dose (28.2% vs. 12.4% at 4 h, P less then 0.01) and maintenance doses (42.8% vs. 24.6% at 4 h, P less then 0.001) in PMs. CONCLUSIONS CYP2C19 polymorphisms have less impact on vicagrel as compared to clopidogrel. Drug exposure and response to vicagrel in PMs were even higher than to clopidogrel in IMs. This article is protected by copyright. All rights reserved.
