In structure-based drug design, the relative orientation of two competitive ligands A and B in the receptor binding pocket plays a central role in the design of high-affinity drug candidates from weakly bound lead compounds. In this communication we report on the observation of interligand spin-diffusion-mediated transferred-NOE data, which have the(More)
The formation of the Tat-protein/TAR-RNA complex is a crucial step in the regulation of human immunodeficiency virus (HIV)-gene expression. To obtain full-length viral transcripts the Tat/TAR complex has to recruit the positive transcription elongation factor complex (P-EFTb), which interacts with TAR through its cyclin T1 (CycT1) component. Mutational(More)
A practical, integrated and versatile U-4CR-based assembly of 1,4-benzodiazepin-2-ones exhibiting functionally, skeletally, and stereochemically diverse substitution patterns is described. By virtue of its convergence, atom economy, and bond-forming efficiency, the methodology documented herein exemplifies the reconciliation of structural complexity and(More)
