In recent years, xanthine oxidase has emerged as an important target not only for gout but also for cardiovascular and metabolic disorders involving hyperuricemia. Contrary to popular belief, recent clinical trials with uricosurics have demonstrated that enhanced excretion of uric

The formation of a DNA "paper-clip" type triple helix (triplex) with a common sequence 5'-d-(TC)(3)T(a)()(CT)(3)C(b)()(AG)(3) (a and b = 0-4) was studied by UV thermal melting experiments and CD spectra. These DNA oligomers form triplexes and duplexes under slightly acidic

Results of a search for correlations between typical group mode frequencies and conformation of -OH and =NH substituents is reported. The study is based on quantum chemical data (HF/6-31G (d, p) and MP2 (full)/6-31G (d, p) approximations) of 13 isomers

Fragment-based lead generation was applied to find novel small-molecule inhibitors of beta-secretase (BACE-1), a key target for the treatment of Alzheimer's disease. Fragment hits coming from a 1D NMR screen were characterized by BIAcore, and the most promising compounds were

Fragment-based lead generation has led to the discovery of a novel series of cyclic amidine-based inhibitors of beta-secretase (BACE-1). Initial fragment hits with an isocytosine core having millimolar potency were identified via NMR affinity screening. Structure-guided evolution of these fragments
