“…As shown by Lurkindule and Simkin [22], two adjacent mutually perpendicular transitions have Furuduy B values (the sign of the Furuduy B term is opposite to the one in the MCD spectrum) which are nearly equal in magnitude though opposite in sign.…”

. Can. J. Chem. 60,291 (1982). The first application of magnetic circular dichroism (rncd) spectroscopy to drug-dinucleotide binding is reported. The mcd spectra have been recorded for complexes of the intercalating anthracyclines carrninomycin, marcellomycin, and aclacinomycin with the dinucleotide CpG. Analysis indicates that drugs having OH groups peri to each anthraquinone carbonyl (i.e. carminomycin and marcellomycin) bind with only one drug molecule in the central hydrophilic region of the nucleotide. By contrast, aclacinomycin, in which one of the anthraquinone carbonyls lacks a peri-OH, is found to cooperatively bind, and has two drug molecules present in the dinucleotide cavity. The cooperativity of binding has been elucidated via an optical titration procedure. Chem. 60, 291 (1982). On rapporte la premiere application de la spectroscopie du dichroisme circulaire magnetique (dcm) a la liaison medicarnent-dinucleotide. On a enregistre les spectres de dcm des complexes formes par les intercalants anthracycline, carminomycine, marcellomycine et aclacinomycine, avec le dinucleotide CpG. Les analyses revelent que les medicaments qui ont des groupements OH enpPri par rapport ?+ chaque carbonyle de l'anthraquinone (comme la carminomycine et la marcellomycine) sont lies a une seule molecule de medicament dans la region hydrophile centrale du nucleotide. On trouve au contraire que I'aclacinomycine, dans laquelle il manque un groupement OH peri pour I'un des carbonyles de l'anthraquinone, est liee cooperativement et que deux moltcules de medicament sont presentes dans la cavite du dinucleotide. On a identifie la cooperativite du lien par I'intermedaire d'une methode de titration optique.[Traduit par ie journal]

“…As shown by Larkindale and Simkin [15], two adjacent mutually perpendicular transitions have Faraday B values (the sign of the Faraday B term is opposite to that in the MCD spectrum) that are nearly equal in magnitude but opposite in sign. The Faraday B values extracted from the MCD spectra are À 2.81 Â 10 À3 and 1.47 Â 10 À3 Bohr magneton (Debye) 2 cm À1 .…”

The magnetic circular dichroism (MCD), induced circular dichroism (ICD) spectra, and the absorption spectra of N-bromophthalimide have been measured. The ICD spectrum of the b-cyclodextrin complex with Nbromophthalimide is also reported. The absorption bands of N-bromophthalimide are assigned.Introduction. ± The electronic structure of N-bromophthalimide has not yet been clarified. The magnetic circular dichroism (MCD) technique has been used by several authors for the elucidation of complicated electronic spectra [1 ± 6]. Recently, the ICD of the b-cyclodextrin complex has been shown to be a very simple tool for the assignment of absorption spectra [7 ± 9].Polarization investigations have also proved to be powerful in the determination of the symmetries of excited-state wave functions and in studying electronic interactions such as vibronic and spin-orbit coupling [10] [11]. Therefore, we have investigated the polarization of the absorption bands of N-bromophthalimide by measuring its MCD spectrum and the ICD spectrum of its b-cyclodextrin complex.
