Switching opioid-dependent patients in substitution treatment from racemic methadone, levomethadone and buprenorphine to slow-release oral morphine: Analysis of the switching process in routine care

open access: yesJournal of Pharmacological Sciences, 2020
Since 2015 slow-release oral morphine (SROM) is approved for opioid substitution treatment (OST) in Germany. The SROMOS study (efficacy and tolerability of slow-release oral morphine in opioid substitution treatment) evaluates the efficacy and safety of ...

Positron lifetime measurements in chiral nematic liquid crystals [PDF]

open access: yes
Positron lifetimes in the isotropic phases of chiral nematic liquid crystal formulations and their mixtures up to the racemic level were measured. The lifetime spectra for all liquid crystal systems were analyzed into three components.

Microwave – assisted reduction of racemic intermediates potential immunosuppressant

open access: yesOrbital: The Electronic Journal of Chemistry, 2012
Immunosuppressant are drugs that reduce the immune response, as important in the treatment of autoimmune diseases and rejection attenuators in organ transplants, the structural point of view generally have a high complexity.

Complete transfer of chirality in an intramolecular, thermal [2 + 2] cycloaddition of allene-ynes to form non-racemic spirooxindoles

open access: yesBeilstein Journal of Organic Chemistry, 2011
A thermal [2 + 2] cycloaddition reaction of allene-ynes has been used to transform chiral non-racemic allenyl oxindoles into chiral non-racemic spirooxindoles containing an alkylidene cyclobutene moiety.

Synthesis of racemic 1,2-diolein

open access: yesJournal of Lipid Research, 1965
1,2-Diolein has been synthesized by protecting the 3-position of glycerol during acylation by means of the pyranyl ether linkage. This linkage is easily broken under conditions leading to very limited isomerization of the diglyceride.

X-ray Crystallography at 170 K of Racemic 2,2'-Dimethoxy-9,9'-biacridine and 1H NMR Study of 2,2'-Diacetoxy-9,9'-biacridine

open access: yesMolecules, 1999
Three derivatives of 9,9'-biacridine, 2,2'-dihydroxy, 2,2'-dimethoxy and 2,2'-diacetoxy have been prepared. The crystal structure of racemic 2,2'-dimethoxy-9,9'-biacridine CHCl3 1:1 complex has been determined and shows an almost perpendicular ...
