C2-symmetric bisamidines: Chiral Brønsted bases catalysing the Diels-Alder reaction of anthrones

open access: yesBeilstein Journal of Organic Chemistry, 2008
C2-symmetric bisamidines 8 have been tested as chiral Brønsted bases in the Diels-Alder reaction of anthrones and N-substituted maleimides. High yields of cycloadducts and significant asymmetric inductions up to 76% ee are accessible.

Reversible Lichtinduzierte Oligomerisierung von Arabidopsis‑Cryptochrom 1 und Antagonismus durch BIC1: Einblicke durch Zeitaufgelöste Native Massenspektrometrie

open access: yesAngewandte Chemie, EarlyView.
Mittels zeitaufgelöster nativer Massenspektrometrie wird der blaulichtabhängige kinetische Mechanismus der Oligomerisierung von Arabidopsis CRY1 aufgedeckt. Die Oligomerisierung verläuft sequenziell von Monomeren über Dimere zu Tetrameren. Während ATP die Assemblierung fördert, inhibiert BIC1 die Tetramerbildung und dissoziiert diese unabhängig von ...

Time‐Resolved Native Mass Spectrometry Reveals Reversible Light‐Driven Oligomerization of Arabidopsis Cryptochrome 1 and Its Antagonism by BIC1

open access: yesAngewandte Chemie International Edition, EarlyView.
Time‐resolved native mass spectrometry uncovers the blue‐light‐dependent kinetic mechanism of Arabidopsis CRY1 oligomerization, proceeding sequentially from monomers to dimers and tetramers. ATP promotes assembly, whereas BIC1 actively blocks and disassembles tetramers independent of light, providing mechanistic insight into the regulation of ...

Early stages of tooth development in the harbor porpoise Phocoena phocoena

open access: yesThe Anatomical Record, EarlyView.
Abstract Here we describe the stages of tooth development in toothed whales on the basis of the harbor porpoise (Phocoena phocoena). The aim of the study was to find out whether these stages are identical to those of other mammals analyzed so far although toothed whales are homodont and monophyodont.
