Chirality Detection Using Nematic Liquid Crystal Droplets on Anisotropic Surfaces
Langmuir 2016 Jun 21;32(24):6140-7.PMID:27244587DOI:10.1021/acs.langmuir.6b00382.
Nematic liquid crystals (NLCs) form helical macroscopic structures through chiral induction when doped with chiral species. We describe a very simple, though highly sensitive method for determination of handedness and pitch of the induced twist in the case of very weak twisting powers of such chiral dopants. A tiny drop-typically less than 10 nL-of the chiral doped NLC is placed on a plate promoting a uniform planar surface anchoring of the liquid crystal director. At the curved NLC-air interface the anchoring is homeotropic and in the sessile droplets we get a locally twisted hybrid director structure with a disclination line extending across the droplet. The configuration of the disclination line (S-like or backwards S-like) reveals the sign of twisting power and extremely large pitch values in the range of 10 mm can easily be measured. We demonstrate the method using the standard NLC 4-cyano-4'-pentylbiphenyl (5CB), weakly doped with the chiral material 2-Hydroxy-2-phenylacetic acid (mandelic acid).
[Biotransformation of zipeprol (Mirsol) in humans. Gas chromatographic/mass spectrometric studies, using ammonia as a selective reactant gas (author's transl)]
J Clin Chem Clin Biochem 1981 Jan;19(1):25-30.PMID:7205156doi
After oral application of Zipeprol (Mirsol) the unchanged drug and nine degradation products were detected in human urine; six of them could be identified. All identified metabolites were detected in the alkaline urine fraction; after acid hydrolysis N-(2-hydroxyethyl)-piperazine was found as an artifact. With respect to the presented results, biotransformation of Zipeprol in man mainly follows three degradation routes: 1. alpha-cleavage leading to metabolite M4; 2. cleavage of the exocyclic N-C-bond of the piperazine ring leading to metabolites M3, M5, M6; 3. benzylic cleavage leading to benzylalcohol (M1); oxidation leading to 2-Hydroxy-2-phenylacetic acid (mandelic acid, M2).
