A naphthyridine carbamate dimer (NCD) is a synthetic ligand for DNA containing a CGG/CGG sequence. Although NCD can bind selectively and tightly to a CGG/CGG sequence, the highly cooperative 2:1 binding mode has hampered precise analysis of the binding. We describe herein the synthesis of a series of naphthyridine tetramers consisting of two NCD molecules connected with various linkers to seek ...

Abstract Introduction Sleep spindles are neural oscillations of frequency between 11 to 16 Hz during non rapid eye movement sleep. They coordinated with hippocampal ripples and slow facilitate memory consolidation by modulating synaptic plasticity. Fast spindles, predominant in central parietal derivations EEG Stage 2 NREM sleep, associated overnight visuomotor skills enhancement, especially th...
