    Article Snippet: 1 SUPPLEMENTARY INFORMATION: Resonance Raman Optical Activity Shows Unusual Structural Sensitivity for Systems in Resonance with Multiple Excited States: Vitamin B12 Case Ewa Machalska,1,2 Grzegorz Zajac,2 Anna Gruca,1,2, Fabio Zobi,3 Malgorzata Baranska,1,2 Agnieszka Kaczor,*1,2 1 Faculty of Chemistry, Jagiellonian University, Gronostajowa 2, Krakow 30-387, Poland 2 Jagiellonian Centre for Experimental Therapeutics (JCET), Jagiellonian University, Bobrzynskiego 14, Krakow 30-348, Poland 3 Department of Chemistry, University of Fribourg, Chemin du Musée 9, 1700 Fribourg, Switzerland EXPERIMENTAL Materials Cyanocobalamin (CNCbl) and hydroxocobalamin (OHCbl) chloride were purchased from Sigma-Aldrich. .. 1,4-diethynylbenzenecobalamin (HC≡C-Ph-C≡CCbl) and a cobalamin ring derivative (CNCbl-Br) were synthesized via reported procedures.1 Studied derivatives are characterized chemically elsewhere.1,2 Spectroscopic measurements (UV-Vis/ECD, Raman/ROA) Raman and ROA spectra of all compounds dissolved in distillated water (c=0.1 mg/mL) were measured using a ChiralRAMAN-2X spectrometer (BioTools Inc.) at a resolution of 7 cm-1 in the range of 2500-250 cm-1 employing the excitation wavelength of 532 nm. ..

    Article Title: Enantiorecognition in a multi-component environment.
    Article Snippet: We demonstrate that enantiopreference in the binding of S,S over R,R astaxanthin (AXT) to albumin manifests itself only for racemic (but not enantiopure) carotenoids.. The observed enantioselectivity is rationalized using chiroptical spectroscopies supported by molecular docking, molecular dynamics and quantum-chemical calculations.. These methods offer a plausible explanation for the observed enantiopreference, as they reveal a unique binding mode of the (3S,30S)-AXT form with the protein in contrast to multiple (random) possibilities for albumin binding with the (3R,30R)-AXT, and also a higher interaction energy of the latter enantiomer with the protein.

    Article Title: Monitoring the Molecular Conformation of Individual Amphotericin B Molecules in an Aggregated State by Raman Optical Activity
    Article Snippet: UV–vis and ECD spectra of AmB solutions were measured on the Jasco J–815 spectropolarimeter in 50, 10, 1, 0.1, or 0.01 mm optical cells with an accumulation of 1–40 scans, a scanning speed of 100 nm min –1 , a step size of 0.1 nm, a bandwidth of 1 nm, and a response time of 1 s. The spectra were background-corrected using the respective solvent measured under the same conditions ( , S1–S6 ). .. Raman (RR) and Raman optical activity (RROA) spectra of AmB solutions in resonance conditions were recorded using ChiralRAMAN-2X spectrometer (BioTools Inc.) equipped with the excitation wavelength of 532 nm, within the 2500–250 cm –1 spectral range, with a resolution of 7 cm –1 and an integration time of 1 s. On the other hand, preresonance Raman (pre-RR) and ROA (pre-RROA) spectra were measured on a home-built ROA spectrometer , at 12.5 cm –1 spectral resolution in the range of 1900–200 cm –1 using the 785 nm laser source. ..
