ic acid (CP5ES) is synthesized and investigated on peptide nanotube (PNT) formation. When the PNT is formed with the maximum number of intermolecular hydrogen bonds between the cyclic peptides, the sequence enables the alignment of the side chains, naphthyl groups, on one side of the PNT. Microscopic and spectroscopic observations of CP5ES crystals reveal that CP5ES forms rod‐ or needle‐shaped molecular
The first total synthesis of exochelin MN is described along with rationally designed analogues. The required L-threo-beta-hydroxyamino acidcomponents were constructed using either Sharpless asymmetric aminohydroxylation reactions or an aldol reaction of imidazolidinone 19. A newconcise procedure for the preparation of the constituent six-membered cyclic hydroxamate was developed. In addition, a

The present invention provides a target gene transcriptional repression inhibitor that can be designed in a sequence-specific manner, a composition containing the same, and use thereof. More specifically, the present invention provides a composition for use in inhibiting repression of gene expression by DNA methylation in a living subject, comprising pyrrole imidazole polyamide or a conjugate of pyrrole imidazole polyamide and a histone modifying enzyme inhibitor, wherein the pyrrole imidazole polyamide or the conjugate of pyrrole imidazole polyamide and a histone modifying enzyme inhibitor is designed so as to bind in a sequence-specific manner to a minor groove of promoter region DNA of the gene.
